Treatment of Young MTF Transsexuals


Media interest in young transsexuals is high, leading to an uncomfortable feeling of possible exploitation in some cases. (UK)

This article discusses the treatment of transsexual boy-to-girl children.  It occurs when an individual is physically born of one sex but is convinced that they are of the opposite gender.   Symptoms usually occur early on in childhood, when the individual will play with toys and wear clothes traditionally used by the opposite sex. [Apologies for this gross simplification to the roughly 0.06% of the population who have a genetic intersex condition]

When allowed to, such children are almost always able to rapidly and successfully assimilate themselves into society as a female, this alone is enough to differentiate them from the experience of most transsexual women who transition when an adult.

It is also perhaps necessary to distinguish between intersex infants, who in some cases are assigned a gender contrary to their genetic sex, and children with a Gender Identity Disorder (GID, aka transgender), also often termed Gender Dysphoria.  While very young intersex infants have no say in their sex assignment or reassignment (which is usually done before they are 24 months old), transsexual children consciously reject the gender in which they are being brought up at some point between two years old and puberty.

Since the 1960's - when Dr John Money, a physician at Johns Hopkins University, made the medical community at last recognise transsexuality - there has been an ever-increasing incidence of Male-to-Female (MFT) of reported GID cases and requests for treatment across all age groups. 

Meaningful statistics on the prevalence of transgender children only began to be collected in the late 1990's. Textbooks published before then commonly state that about 1 in 10,000 children have GID, this number seems be based on a single study made in the 1970's.  

In 1997 Press for Change reported that in the UK there were 600 transitioned transgender children.  This was less than 1 in 20,000 children.

Note:  The figure of 600 excludes the very small proportion of "XY" intersex children born in the UK with ambiguous or malformed genitals who are assigned to the female gender by doctors while still a baby, perhaps 20-40 each year deriving from USA figures.  There are also many children with "male" genes who are identified at birth as female and then brought up as girls, for example there are perhaps 3000 "XY" women in the UK who were born with Androgen Insensitivity Syndrome. 

However, since 1997 the recorded number of transgender children has exploded.  New sources of information such as the internet and TV documentaries mean that children and parents are no longer accepting as gospel the advice of an experienced and over-loaded doctor or psychiatrist.  The growth in reported GID cases among teenagers has been extraordinary.  For example in 1999 alone, the number of transgendered people under 22 in the "gender reassignment" program at New York's Michael Callen-Audre Lorde Community Health Center tripled! 

By the early 2000's the UK's NHS was suggesting that 1 in 4000 children was transgender, the Netherlands and Belgium 1 in a 2000, whilst the number in some Asian countries was reaching 1 in 500 (almost all Male-To-Female). 

A UK study published in November 2005 said that there were 2,000 young transsexuals in the country age 15-19, about 1 in 2,500 of that age group.

The newly launched UK Charity Gires had a sceptical reaction when it claimed in 2010 that there were now 26,000 "young people" in the UK with gender identify problems, and that the number would soon reach 100,000, i.e. about 1 in 130 of the UK's population under age 18.  However, in 2016 the UK's NHS website was suggesting that 1 child in a 100 had gender problems.  A study of 8000 students in New Zealand also arrived at a figure of less than 1 in a 100. 

The growth in the number of transgender children in the UK can be illustrated by the exponential growth in referrals to the Tavistock and Portman NHS Foundation Trust in London - the primary UK centre for children and adolescents with GID:

Gender Assigned at Birth 2009-10 2010-11 2011-12 2012-13 2013-14 2014-15 2015-16 2016-17
Male 56 72 88 121 188 270 490 616
Female 40 65 118 188 278 427 939 1400
Child of transsexual parent 1 2 2 5 2 0 0 0
Total 97 139 208 314 468 697 1419 2016
Percentage AFAB 41% 47% 57% 60% 60% 61% 66% 69%

The UK's NHS reported that the average (mean) age of patients being referred to its gender identity clinics in 2013 was 42.  In 2015 it was just 30 after repeated huge annual rises in the number of teenagers with gender disorders - the Sun newspaper suggested 1000%

The balance has also changed from female-to-male (FTM) children greatly outnumbering female-to-male (FTM), to the exact opposite - the Tavistock clinic now has more than two FTM referrals for every MTF.  The referral of young people assigned female at birth (AFAB) to NHS gender clinics now outnumber male at birth by more than two to one, although among adults the opposite is still true.  One study estimates that "just" 2-6% of natal boys exhibit cross-gender characteristics, compared to 5-12% of girls.

individuals suffering from GID when when they first realised that their gender did not match that assigned at birth.
Undoubtedly the overall growth in numbers is largely the result of increased access to information.  A child today with 'gender dysphoria' - the catch-all term for disconnect between body and gender identity, will almost certainly have heard about transsexuals and transgender long before they reach the critical point of puberty.  Many children with GID problems learn about transgender from TV shows and documentaries and then go on-line, looking up anything and everything they can find out about transsexuality, and start to chat and email with other transsexuals.  For example, the 2014 American reality TV series I am Jazz starred a 14-year old transgender girl, Jazz Jennings, whilst UK television had the series My Transgender Kid. 

With the increasing awareness and more favourable publicity given to transgender, MTF children who in the past would have suppressed their female gender, or at least defer dealing with it openly until reaching adulthood, are now coming forward while still a child.   In most cases their families respond very positively and supportively, but occasions of outraged parents and internal family battles about how to deal with a would-be daughter will never cease completely.  Perhaps a good indicator of the changed situation is that by 2016 about 90% of UK primary and secondary schools had policies to support transgender students.

There continues to be a reluctance by the general medical profession to pro-actively treat gender identity disordered children.  In the UK a referral to the few specialist NHS clinics is the best outcome, although these are being overwhelmed by numbers that are roughly doubling every year.  It is also worth noting that young transsexuals (i.e. under age 20) seeking and obtaining medical help and treatment at these clinics are still vastly outnumbered by their older counterparts - most of whom bitterly regret their years of delay.  But a major problem is that the NHS's waiting list for GID treatment is two years, and additional resources are desperately needed.  There is strong case that younger transgender patients should be prioritised over older patients - unfair though this may seem to the later.

Young transgirls tend to immediately and successfully go stealth after transition, unlike their older counterparts.  The girls pictured on this page are thus exceptionally brave about their transsexuality - or had little choice as they were out'ed by the media.

Sex Re-Assignment

A person's sex can be determined or judged by many factors, including:

  1. Legal Sex:  In the UK the infamous ruling by Lord Justice Ormrod, irreversibly determined that this was the sex stated on the original birth certificate - although since 2004 the Gender Recognition Bill has overturned many aspects of this ruling.
  2. Hormonal Sex:  Based largely upon male type testosterone plasma levels, or female type oestrogen and progesterone plasma levels.
  3. Chromosomal Sex:  Male "XY" or female "XX" genes as determined by a karyotypic study (in rare cases there are other combinations.
  4. Internal Sexual and Accessory Organs:  The presence of male (testes) or female (ovaries) gonads, and male (e.g. vasa deferens, ejaculatory ducts and prostate gland) or female (e.g. uterus, vagina, fallopian tubes) accessory organs.
  5. External Sexual Characteristics:  Male (e.g. penis, scrotum) or female (e.g. clitoris, labia majora) appearing external genitalia, and other male (e.g. beard) or female (e.g. breasts) appearing secondary sexual characteristics.
  6. Gender Role:  The sexual role a person lives in, and the sex they are perceived as being.  A reasonable definition is "A social status usually based on the convincing performance of femininity or masculinity".
  7. Sexual Identity:  The physical sex a person considers themselves to be when fantasising romantically, or when sexually attracted to someone.
  8. Gender Identity:  Despite the increasingly widespread use of this term since 2000 it's never been satisfactorily defined.  A successful merging of gender role and sexual identity is perhaps the ideal outcome.

Maxine (born Maksim) transitioned at age 14, had a "nose job" at 16, started hormones at 17, had SRS at 20 and is shown age 21 in the main picture. (Moldavia / Germany).

It is quite possible for these factors to disagree and contradict, e.g. a post-operative transsexual person may have a male birth certificate, a male karyoptype (XY genes), no internal female sex organs, female appearing genitalia and secondary sexual characteristics, live and identify as a woman,  but be sexually attracted only to other women and in a lesbian relationship.

Factors 6, 7 and 8 are commonly and unfortunately combined under the term "gender-role", but I prefer to keep them separate when possible.  A particularly confusing but frequent use of the word gender is in the phrase "Gender Re-Assignment Surgery"  (GRS).  It's essential to differentiate between a person's physiological sex (factors 4 and 5), and a person's social & mental gender (factors 6 and 7), surgery can't ever change the later and phrase "Sex Re-Assignment Surgery" (SRS) is a better, although still seriously exaggerating, description of what surgery can achieve.  


For most children their legal, chromosomal and physical sex agree with their mental gender and preferred gender role.... but not always.  As already mentioned, children with gender identity problems are described as having gender dysphoria.

Establishing a gender identity is a process that most people take for granted, but that no one completely understands.   

Three theories of gender development (click to enlarge)

Scientists and sociologists agree that traditional gender roles are in many ways socially constructed, e.g. girls learn to wear dresses and boys learn to wear trousers.  But no one seems to understand what makes a transsexual child raised in a male gender role embrace the female role as her own and vice versa.  Nor can anyone explain why many intersex children raised as one sex eventually migrate back to the gender that their genetics or their prenatal hormonal environment would have predicted.

John/Joan (David Reimer) - may he RIP.(USA)

Bill Summers, a professor of medical history at Yale who has studied the science behind gender and sexuality says "You have to learn somehow what it means to be a boy or a girl.  You don't come born with this idea.  But enough people say, 'I always knew I was a boy but I was raised as a girl' that I can't doubt they have these feelings."

Summers points to the work of Dr John Money who became famous in the 1960s for recommending and surgically facilitating the transition of a young boy with a botched circumcision into living as a girl - the so called "John/Joan" case.  Money initially declared the gender re-assignment to be a success, but his work was later undermined when the girl grew up with a masculine gender identity anyway.  Summers notes that "the whole idea [was] that given hormone treatment and the right social environment, you can determine gender identity.  It's not really quite so simple."

The bottom line seems to be that sociologists and psychologists still don't know where gender identity comes from or why - but it is unlikely that either biology or society operates totally independently from the other.  The only current certainty seems to be that when a young child decides that they are a boy or a girl and this decision contradicts their supposed physiological sex, the result is much anguish and cost to the child, the parents and the medical profession.  

Sexual Identification of Transsexual Children
It is important to note that many boy-to-girl "transsexual's" do not consider themselves to be transsexual - indeed they often actively dislike being called such - they just consider themselves to be girls and in a medical context suffer from Gender Identity Disorder (GID) The reality is that young transgirls often associate the word "transsexual" with TV documentaries featuring strange balding middle-aged men, married with children, who at the end of the programme still look, sound and behave like men wearing wigs, dresses and too much makeup to their very discriminating eyes and standards.  Young transgirls simply cannot relate themselves with these examples of transsexuality - their problems are totally different, and even passing is rarely one of them.

Zach Avery, age 5 (UK)

Whilst there is no such thing as the typical young child with GID, perhaps a good example is Zach Avery.  At first, he seemed to be a 'normal boy' but when age 3 he turned around and told his mother, Theresa, "Mummy, I'm a girl".  She assumed that he was just going through a phase and just left it at that, but Zach started to insist on wearing his sister's clothes and would become upset if anyone referred to him as a boy.  Theresa notes that "He used to cry and try to cut off his willy out of frustration".  His parents became increasingly worried by Zach's behaviour and took him to the doctors.  After numerous consultations and observations, he was officially diagnosed by NHS specialists as having GID, and transitioned age 4.

A key, if obvious, differentiator between transsexuality emerging in children and the far more numerous instances of it emerging in an adult is the pre-puberty age at which noticeable cross-gender behaviour appears in the former group.  This has been confirmed by numerous studies...

The results of an old study analysing the age at which transsexuals first sought medical treatment in Germany.  The exclusion of 18 and under is very notable.  It's very likely that a more recent study would show a dramatic shift towards 24 and younger. 

In one study, two thirds of transsexual boys were aware that they belonged to the opposite sex and exhibited such behaviour by age 5, and 77% by age 10. 

Another study of 137 MTF transsexuals, 70% exhibited cross-gender behaviour before age 10, and another 20% before age 15. 

A third study of 121 transgender individuals between age 18 and 65+ gives a modal average of 5 years for the age when the participants began to question their assigned gender, and a mean average of 7.9 years.   Just 4% first had doubts about their gender after age 18.  Over 80% of the participants in the study were assigned male at birth.

Riley (formerly Richard) "Grant", age ten, she never doubted that she was a girl and transitioned when age 7. (USA)  Source: Heidi Gutman/ABC

It seems that until the 2010's most young transsexuals suppressed their doubts about their assigned gender, as one later said "my overriding need was to a keep it quiet and not come out and seek acceptance that 'God has made a mistake'".

But there were brave exceptions.  For example Richard ('Richie') always wanted to wear dresses like his sister, when age two and a half his mother caught him trying to cut his penis off with nail clippers, saying "this doesn't go here".  At age 7 he was finally diagnosed as having Gender Identity Disorder, his parents changed her name to Riley Elizabeth and let her go to school as a girl - where she blossomed from a "sad confused little boy into a happy young girl".  The financial burden of Riley's medical care had been crippling, but her parents had no doubts - "seeing Riley's happy face now, it's worth every penny".

It seems that at least three-quarters of gender dysphoric children will eventually have sex re-assignment surgery (SRS).

If clinical testing finds that the following conditions apply:

  1. onset of a desire to belong to the opposite sex before puberty

  2. cross gender behaviour and social role without sexual arousal

  3. dislike for one's own secondary sexual characteristics

then core transsexuality, commonly known as "true" or "primary" transsexuality, is likely to be confirmed and appropriate sex-reassignment treatment should be started. 

Nicole Roukema
Nicole Roukema (Netherlands) was born Neils but knew that she was a girl by age 3.  She  transitioned age 13 and plans to have SRS surgery when 18.

However there still remains considerable reluctance by the medical profession to supportively treat a physically normal boy with gender identity problems - a boy who's adamantly insistent that he's really a girl.  The sex re-assignment of babies and very young boys became medically acceptable in the 1970's and 1980's (indeed, perhaps too common) - but has since become discredited and unfortunately there has been a carry-over affecting young transsexuals.  It seems too often require courageous and forceful parents before doctors will medically facilitate the transition of a minor.

Another interesting (aka confusing) development since 2010 is that several studies suggest that more than two thirds of boys diagnosed with gender dysphoria when pre-puberty, accept that they are actually male when post-puberty.  This however opens a host of questions about the amount of medical support that they received, their access (or lack of) to puberty blockers and hormones, an inability to transition, social and family pressures, sexual orientation, and the long term physical and mental consequences - particularly on those girls still diagnosed with gender dysphoria.

An understandable reluctance to "come out" to one's parents remains probably the greatest single obstacle to the early and successful treatment of many transgirls.  On the other hand, things do seem to be improving and television and the Internet is playing a key role in this - these days most transsexual children first learn about "transsexuality" from TV programmes, relating to this condition they - and often their parents - seek further information via the Internet (now an extraordinarily valuable resource) and from books.

Danielle (formally Daniel) Gomez (Mexico/USA) had SRS at age 17, while still at High school.  Her supportive mother has written a book about Danielle's journey to womanhood.

It is impossible to underestimate how important the understanding and support of parents is for a young transsexual her eventual success in life.  It is also difficult to underestimate how much emotional strain having a transsexual child can impose on his/her parents.

Many parents become a pillar of support and understanding, indeed there are many instances of parents going to extraordinary lengths and expense to aid their new daughter - for example moving house so they can go to a different school and avoid anyone who knew them as a boy. 

In another positive example, Jamie never felt herself to be a boy, and when at age 11 she finally told her parents "You think that I am a boy, but I am a little girl!", they accepted her choice and she is now living very happily and confidently as their daughter.

20 year old Rachel transitioned when 17, but still visits her parents as their son Daniel. (UK)

On the other hand, there are also instances where the child tells the parents and the result is a nightmare of arguments and pressure.  Rachel (formerly Daniel) describes how when she told her parents at age 17: "They didn't shout at me but the conversation was very heated.  Mum got upset - although she said she'd guessed a while ago - and Dad was annoyed.  They both said they didn't want me to dress up in the house and that I'd always be Daniel to them.  ...  My parents have been good to me, but they'll always see me as their son."

For many years Amy (shown age 19) received psychiatric treatment to "cure" her gender dysphoria.

Rachel is actually luckier than many girls.  Enforced visits to a suitable psychiatrist (suitable for the parents at least) to treat the child's gender disorder are common.  Perhaps in a few cases a "cure" is achieved, but more commonly the child suppresses his/her transsexuality, and if he persists then an eventual total rejection by one (usually the father) or even both parents may well occur.  For example, Brazilian Roberta Close was disowned by her father, and only reconciled years later.  While now a successful model and actress, for several years in her teens Roberta descended in to the seedier side of life that all too many transsexual women go through in order to earn a living.

Katie shown
age 16 and while still in High School.  She transitioned when age 10 and her parents fought for her right to attend school as a girl.  Although on female hormones for many years, she was still waiting for her SRS in early 2003, age 19. (USA)

Often transsexual children feel unable to tell their parents about their feelings and needs.  This usually means that a public admission of their transsexuality is deferred to adulthood - and the delay is always much regretted.  But also the resourcefulness of children should not be underestimated.  For example, one textbook (Man and Woman, Boy and Girl) describes how a woman secretly obtained and took hormones while still a young teenage boy.  Her concerned parents eventually took her to hospital for tests to help determine the cause of the resulting physical changes, but she had had enough warning to stop and let her system clear.  The doctors concluded that the changes were spontaneous and natural (some degree of gynaecomastia - male breast development - is quite normal in mid-puberty boys), and told the parents not to worry.  

Young transsexuals such as Kelly benefit enormously from blockers and early use of female hormones, but some fundamental physical aspects remain. (UK) 

Medical Guidelines for the Treatment of Transsexual Children
The widely followed HBIGDA Standards of Care of Gender Identity Disorders, a document which has previously (and increasingly controversially) been against the treatment against the hormonal treatment of under 16's, has relaxed its rules somewhat in the latest (2001) Version 6.  It now states that:

"Adolescents may be eligible for puberty-delaying hormones as soon as pubertal changes have begun. In order for the adolescent and his or her parents to make an informed decision about pubertal delay, it is recommended that the adolescent experience the onset of puberty in his or her biologic sex, at least to Tanner Stage Two."  [on average this means about age 11 for biologic females, age 12 for biologic males]  .....

"Adolescents may be eligible to begin masculinizing or feminizing hormone therapy as early as age 16, preferably with parental consent. In many countries 16-year olds are legal adults for medical decision making, and do not require parental consent. ....

"Any surgical intervention should not be carried out prior to adulthood, or prior to a real-life experience of at least two years in the gender role of the sex with which the adolescent identifies. The threshold of 18 should be seen as an eligibility criterion and not an indication in itself for active intervention."

Maité (formerly Alexandre) Schneider started hormones age 18, Shown age 21 before SRS
. (Brazil)

Although still not coming out in favour of starting feminizing hormone treatment at a normal puberty age and delaying any sex change surgery until at least age 18, the standards do at least now allow the treatment of very young adolescents with puberty-delaying hormones and thus help prevent the socially and mentally disastrous development of normal male [secondary] sexual characteristics and appearance in an under-16 MTF school girl.  In a best case this now allows age critical medical treatment to stop male characteristics developing, but female sexual characteristics optimised by early hormone treatment are still banned.

In its defence, the "Standards of Care" is clearly and understandably concerned about some instances of unsuccessful boy-to-girl gender re-assignment of intersex babies, such as the highly publicised failure of the gender re-assignment David Reimer (aka the "John/Joan" case), and wants to avoid any future repetition.


Puberty can be defined as the biological developments which change boys and girls from physical immaturity to biological maturity.  For a transsexual child an inappropriate puberty sets a mountain that can never be full conquered, while an appropriate puberty offers a greatly eased path to a gender reassignment, both physically and psychologically.

Puberty is often a nightmare for 'gender dysphoria' children according to Cohen Kettenis, Professor of Psychology at the Medical Centre of the Free University in Amsterdam, "They develop an enormous dislike for their body."  Most children seen by Professor Cohen react with horror to the changes that occur in their bodies at puberty.  It appears that their so-called "transsexual" feelings become much stronger and they do not feel at home in the body that they now developing.  Margaret Griffiths of the Mermaids support group says very similar things, "Some girls and boys go through Hell at puberty, they have few friends, they are bad in the school, because they can concentrate on nothing, and some have suicidal thoughts."

Lauren Foster, nee Shipton.  She had SRS at age 18 and became a successful model (South Africa / USA)

When - at age 10 - Riley (who had been living as a girl since age 7) was warned by her mother that nature would soon start turning her in a man, her reaction was a horrified "Please don't let that happen ... please!". 

Although the child may not admit to his transsexual desires at this stage, the parents will often start to have some concerns about their son.  The onset of puberty is a critical point as the child is faced with his own undesired physical masculinisation, often combined with a great jealously of girls and their physical changes, by age 15 some 90% are exhibiting feminine behaviour.  This is the point where many transsexual children finally admit to their wish to be a girl and they, or their parents, seek help. 

Kelly at the start of her transition. (UK)

One now happily post-SRS girl described how she felt at puberty: "That was the hardest.  My own body was staging a mutiny, even."  At 16 she finally confessed to her secret to her parents who took her to several doctors but they wouldn't help, "I knew I couldn't be happy letting my body masculinize on and on.  And so at 17 I graduated from high school and found hormones on the street."

Zoe, age 21, concurs about puberty: "When puberty arrived I was repulsed by my erections and deepening voice.  At times I felt suicidal." 

 Jamie Cooper was 12 when she wrote her mother a letter saying that she should have been born a girl, they sought medical advice and were told that it could just be puberty, the feelings deepened but she had to wait until she was 16 before receiving hormone treatment - she transitioned on her 16th birthday.

How hormones affect a girls body during puberty (click graphic for large version)

A lot more information about puberty and its effects is given in the separate article here.
Body shape is controlled by oestrogen and testosterone.  During puberty, while boys are amassing bone and muscle thanks to their developed testes pumping out androgens (particularly testosterone), a high concentration of oestrogen in the female body results in the typical girl gaining nearly 35 pounds (15kg) of so-called reproductive fat deposited on the hips and thighs rather than on the waist.  Another female hormone, progesterone, also plays a significant and complementary role, most particularly in the development of breast tissue. 

Oestrogen levels in Women

Testosterone levels in Men

The changes in hormone levels at puberty are dramatically different between boys
and girls, unsurprisingly this results in dramatically different physical changes.

Professor Cohen's policy is that if it appears that the gender dysphoria feelings are becoming stronger, then they should be prescribed puberty blockers to temporarily halt puberty until they are 16.  When they are 16 and quite certain that they have the wrong body, they can be prescribed hormones as well as to begin to change their outward appearance to more closely match their chosen sex, "After that comes the actual sex-change operation".

The Importance of Early Treatment
Unfortunately, because of the John/Joan case, and mistakes made in the past when dealing with intersex children, recent medical studies have tended to emphasise the minority (about one quarter) of gender disordered children who don't eventually have SRS, and the disadvantages of early gender and sex-role re-assignment.  In particular, many advise against early genital surgery or irreversible feminising hormonal treatment.  But they neglect to consider why so many young transsexuals eventually have SRS despite the immense "corrective" pressures often exerted on them, nor do they consider whether those that don't have SRS would have perhaps enjoyed their lives more as a woman than they now are as a man.

Kristel (born Jeremy) age 11.

Nevertheless, many gender clinics seem to be moving the earliest age for the prescription of hormones rather than puberty blockers to transgender children from age 18 to age 16. All the accumulating evidence is that the earliest possible hormonal treatment has significant physical and mental advantages - even compared to puberty blockers.  

There are two key problems with puberty blockers for a boy to girl:

1. Boys tend to start puberty later than girls.  It is very unusual for a boy to be prescribed puberty blockers until age 11 or 12, by which time most girls are several years in to their puberty.

2. Puberty blockers stop the development of male secondary characteristics but they don't stop the clock. The human body seems to be fundamentally geared for dramatic sexual development between ages 10 and 15.  Stopping blockers and beginning female hormones when age 16 is simply too late, the frequently disappointing breast development of many such girls who start taking oestrogen in their late teens is strong evidence of this.

 If a boy is diagnosed as a transsexual then a failure to immediately start treatment is not only deferring the inevitable in the vast majority of cases but is doing so at a considerable cost to the child's future as a girl and woman.  It's indisputable that the earliest possible transition and pre-puberty hormonal and surgical treatment will offer most boy-to-girl's massive psychological and physical benefits.  

Ariel Nicholson posted on social media these photos of herself.  Clockwise from left: age c.4, age c.9, age 15, age 18.  (USA)

An example of this is Ariel Nicholson Murtagh.  He knew from a very young age that he was actually a girl.  Her mother, Kerry, was very supportive and battled for his right to transition and receive medical support. [Sadly her father was far less supportive, and this was a major factor in the marriage ending.]  When age 10, his mother let her transition and change her name to Ariel, she also began injections of Lupren to suppress her puberty and prevent her voice from breaking.  In 2015, age 14, she appeared in the PBS documentary “Growing Up Trans”, talking with a therapist from the Ackerman Institute about wanting to take oestrogen.  She finally started taking hormones age 15.  The PBS documentary resulted in her being discovered as a model, her first catwalk was for Calvin Klein in September 2017, in 2018 the influential models.com website added her to their "Hot List". 

Jonas and Nicole Wyatt (USA)

Another example of the results of early medical treatment is Wyatt and Jonas Maines.  They were born identical twins, but from a early age Wyatt rejected being a boy.  His parents were very supportive, and at age 11 the twins became brother and sister when Wyatt transitioned  and changed her name to Nicole.  The family sought medical help from the Children’s Hospital Gender Management Services Clinic in Boston, USA.  The clinic prescribed Nicole with puberty blockers and female hormone injections.  The dramatic effect of this treatment is shown by the fact that at age 14 Jonas (in mid-male puberty) was 167 cm tall (5ft 6 inches) and weighed a 52 kg (115 pounds), whilst Nicole was still a petite 155cm (5ft 1inch) and weighed only 45kg (100 pounds).

Teddy Quinlivan (USA).

Supermodel Teddy Quinlivan, risked her career when in 2017, age 24, she decided to tell a CNN reporter that she was transgender.  She emphasised that her success as a female model was due to transitioning and beginning hormones at a young age:

Since I transitioned when I was 16, I’ve been living as a cis female.  I was very lucky, because I won the genetic lottery – I looked a certain way and my voice hadn’t dropped.  That privilege gave me a lot of confidence to walk down the street, date, and (work) in the fashion industry, where people would presume I was a “normal” girl.’ 

I actually started taking hormones when I was 17. But transitioning isn’t just a matter of growing out your hair, wearing heels, and piercing your ears. Taking hormones affects your mood; it’s like being born again. It changes not only the way you look but the way you see the world. While my career was taking off—I was signed when I was 22—I was going through a lot emotionally. All of a sudden, I was acting like a prepubescent girl. And since I was concealing my identity, no one understood.

Young boy-to-girl transsexuals have no doubts about their female gender - and early medical treatment can help them easily pass as a girl.

Early transition and commencement of treatment will permit the transsexual boy-to-girl a female childhood, a normal puberty (excludinoman.   It's an absolutely priceless experience if a transsexual girl goes through her adolescence and growing-up as a female, with a circle of same-sex girlfriends.  It's a period of time when her personality, identity and attitudes are forming, and the stage for the rest of her life is being set.  She will have irreplaceable girlish memories and social adjustments that a transition later in life can never give her.  Her life experience will be much more like that of other women, she will be able to talk more easily about parts of her past, her school days, and even have photos to show her future boyfriends.  For many girls, denying these experiences to her and enforcing an unwanted male gender is simply a disaster.


, age "mid-20's"

One successful transsexual woman 'Anna Taylor' describes her early experiences: "It never occurred to me that I was a boy. I just wondered why I had something extra. I had sessions with a child psychologist and my parents were told to bring me up neutrally.  My mother tried, but my dad would slap me if he caught me playing with dolls.  My mother says that if it had been up to her she would have banged on every door to let me become a girl, but my dad wouldn't stand for it."

Monica was born a boy named Morten, but always rejected being assigned as male.  By her teens, her parents were worried that she was becoming suicidal and supported her transition.  She finally had full SRS at age 22. 

Shown age 45, Anna Taylor transitioned at 11 and began hormones at 13 after her parents found a Dutch doctor willing to prescribe them.  Surgeons refused to perform her SRS until she was 18, she had surgery three days after her 18th birthday. (UK)

Anna ran away from home several times until, aged 8, she went to live with her grandparents who were prepared to bring her up as a girl.  At age 11, started at a new school where the headmaster was very sympathetic and agreed to let her register as a girl.  "For the first time no one was laughing at me. From being very withdrawn, I became very bubbly and outgoing.  The only allowance they made was that I had to change in a separate cubicle for games and use the teachers' toilets.  The school was afraid of another girl seeing something they shouldn't.  [But] I got very depressed when the other girls started wearing bras.  My own doctor wouldn't prescribe hormones for me at 13, so my grandmother took me to Amsterdam to find a doctor who would.  Within a few months I'd grown very small breasts.  Doctors agreed that I should have had gender reassignment surgery when I was younger but now that I was an adolescent, I would have to wait until I was 18."

A recent follow-up study of sex-reassignment in 22 adolescent transsexuals (ten started hormones under age 16, twelve under 18) found that post-operatively in all cases all signs of gender dysphoria had disappeared, they scored normally in psychological tests and they were socially functioning well.  Not a single girl/boy expressed feelings of regret concerning their decision to undergo sex reassignment.  The study concluded that with careful preliminary screening, starting sex reassignment procedures before adulthood results in favourable post-operative functioning.

Effects of Early Hormonal Treatment
A doctor now treating transwomen says: "I began working with transgendered people in their 20s. The people in their 20s were socially in good shape. But they were having trouble getting their physique to conform to their identity. I knew the twenty-somethings could have better chances of passing if they were treated earlier."

Early hormone use (i.e. during puberty) in a trans-girl allows a typically normal female body shape to develop, with significantly more fat and less muscle than otherwise, the girls post-puberty body shape and "figure" will become far closer to female than male norms in its proportions. 

Amanda Lear may have started hormones at 15 - depending what birth date you accept.  (Born in Vietnam, lives in France,

In general, increased levels in the blood plasma of oestrogen and progesterone will stimulate and promote the growth of female secondary sexual characteristics (breasts, fat distribution, pubic hair pattern, ...) while the reduction in the levels of androgens such as testosterone will, if early enough, completely prevent the development of male ones (deepening of voice, facial hair, muscular development, ...).

Female hormonal treatment has a dramatically greater effect if begun before a male puberty has started (on average age 12, but plus or minus 2 years) than after a male puberty has completed (on average 17, plus or minus).  This is a severe problem given the great reluctance to doctors to assist transsexual patients under age 18.  Incidentally, the anticipated and achievable benefits from starting female hormones decline rapidly in the decade after puberty ends.

Maximum possible feminisation occurs if hormonal treatment begins before a male puberty would have start started.  Very conveniently, girls tend to start puberty two years earlier than their male peers, so high dose hormone therapy intended to initiate a full female type can be safely started by age 11, although it in practice it is often deferred to 12 or even later, particularly if the individuals physical development allows that.  If her testes were removed in infancy or childhood, then for health reasons low level hormone therapy should be begun by age 9 - an age at which many girls begin to notice some initial puberty changes, in particular the development of breast buds. 

As indicated already, surgeons have become very reluctant in recent years to perform a bilateral orchiectomy on even young intersex patients, let alone gender dysphoric boys; however failure to do so does accept the slight risk that even suppressed testes might still produce enough androgens for a very sensitive body to react to them.  The nightmare scenario is a confused body going through a double male and female puberty - the girls hips broaden, and her breasts swell under the influence of oestrogen therapy, but simultaneously her voice deepens and facial hair appears due to the testosterone being produced by her testes.

After legal debate Johanna (formally Johannes) Bulow was allowed puberty blocking drugs at age 12 and female hormones at 13.  She's shown age 14, and (inset) age 15 holding her new identity papers. (Germany)

Surprisingly there seems to have been no serious medical studies examining how pubertal development differs between genetically 'XX' cis-girls with estrogen producing ovaries and young 'XY' girls (commonly intersex rather than transsexual) on hormone replacement therapy (HRT) following early orchiectomy.

The Skeleton
Anecdotal evidence is that reduction in levels of "male" androgen hormones caused by oestrogen treatment has a slight effect on the skeleton - reducing male type rugged'isation and enhancing female type features, for example slightly broadening the pelvis and helping reduce the girls adult height (by perhaps an inch or two) compared with if she had experienced a male puberty.  However, while hormones play an important role in post-pubertal body shape, it seems that the male "Y" chromosome is dominates skeletal growth in a transgirl, she will thus still experience some a degree of skeletal masculinisation, even if she commences female hormone treatment at 11 or 12.  In general, her physical characteristics as determined by her skeleton (height, skull, hand & feet size) will lie between the male and female norms post-puberty - although more towards the former than the later.  This not necessarily bad as the western idea of feminine beauty is for tall and leggy women.  As an adult, the woman will typically be both tall compared to the average woman (67½" vs. 64¼") and have long legs - both absolutely (32½" vs. 30") and relative for her height, ideal for those girls with ambitions as a model!  [For more information about average male and female body sizes, see the article on this site]

 Lucy (formerly Richard) transitioned at 16 and a BBC documentary followed her having breast augmentation just days after her 18th birthday allowed this. (UK)

In a genetic girl, her increasing production of oestrogen during puberty causes her skeleton to mature so that growth eventually stops.  Oestrogen treatment can speed up this bone maturation by accelerating the completion of growth in the growth plates (the zones of growing cartilage near the ends of children’s bones) and thus suppresses growth somewhat, by up to two inches.  Paediatric endocrinologists sometimes prescribe large doses of oestrogen (usually Ethinyl Estradiol) for a period of several years to deliberately restrict growth in excessively tall girls, and the same technique can be used to help induce in young transsexuals a final height in the typical female range of 61 - 67". 

However, obtaining supervised treatment for a transsexual boy-to-girl is difficult, arguing that height is not a disease; endocrinologists are becoming increasingly reluctant to treat even a genetically female "XX" adolescent unless bone growth X-rays show that excessive adult height for a female (over 71") appears likely. 

The Brain
During puberty the human brain undergoes its final stage of growth and development.  Despite decades of speculation there is very little evidence for significant differentiation based on genetics (XY vs XX).  It's even less clear if there are gender related differences - perhaps stimulated by hormones.  The study of transgirl's and transboy's may lead to some important results.

Hormone Treatment for Young Transsexual Girls 
A treatment model developed for intersex children with male testes but assigned as female has occasionally been applied to young transgender children.  In order to maximise physical feminisation, low level oestrogen treatment of the young transsexual boy-to-girl often begins at age 8-9 years.  Before the onset of a natural puberty (at about age 11, but it can vary ±2 years) a bilateral orchiectomy (castration) is performed to remove the testes and hormonal treatment is then increased (additional oestrogen, later supplemented with progesterone) to initiate a female type puberty.  

Nina (formerly Guido) transitioned at age 11.  She's is pictured nearly 3 years later, age 13. (Netherlands)

When an orchiectomy is performed before puberty, the results in terms of increased physical feminisation and decreased masculinisation are much more dramatic than when it is done after puberty.  However, many Western doctors are very reluctant to perform any irreversible surgery, or even prescribe feminising hormones, for a transgender child under age 16.  Instead, they often prescribe GnRH analogues (commonly known as 'puberty blockers') such as Zoladex (Goserelin Acetate) and Lupron (Leuprolide Acetate).  These prevent or dramatically reduce gonadal hormone production, including testosterone, thus preventing the onset of the masculinising changes of adolescence.  The drug is administered with a nasal spray, or via a weekly or monthly subcutaneous injection into the abdomen.  While the treatment does nothing to promote female physical characteristics in the girl, it does prevent or greatly slow male type puberty with its physical effects, and several Dutch studies have confirmed the effectiveness of such treatment. 

Puberty blockers have the important advantage of gaining time whilst the transgender child considers and reconfirms their choice of gender.  The 2010's have seen a huge increase in the number of apparently transgender children, but anecdotal reports indicate that up to a third change their mind within a year of transitioning.  Another big advantage of blockers for a boy-to-girl is that they don't have to start taking a high dose of oestrogen whilst pre-teen.  An 11 or 12 year old boy is actually shorter than the average girl of the same age, and starting oestrogen therapy at that age may restrict their height to under 5ft (about 151 cm) - very short even for a girl.  Obviously every transgirl is different but delaying oestrogen treatment until age 13 or 14 is likely to result in an average female height, whilst 15 may result in an above average height for woman, but not excessively so (i.e. ideal for a model).

Unfortunately GnRH analogues are expensive drugs, but they are to be much preferred in adolescents over the cheaper anti-androgens such as Aldactone (Spironolactone) and Proscar (Finasteride) which are commonly prescribed to post-puberty transsexual women, but which are increasingly suspected of having unwanted side effects, including reduced breast growth.

The UK's NHS has become one of the most progressive medical organisations in regards to the  treatment of transgender children.  They will now - if appropriate - prescribe hormones from age 12, and puberty blockers before that.

Even if it not possible to begin female hormonal  treatment before a male puberty has commenced, the results can still be remarkable results if started whilst the body is still at its most receptive age - the critical puberty years between about 11 and 17 (depending on the individual), but the earlier the better.  It is no coincidence that so many transsexual women who famed for their looks had begun taking hormones by 17 - Jenny Hiloudaki, Tula, Hari-su, Roberta Close, Dana International, etc.

Riley, age 9

A typical example is Nicole Vicky Eriksson, born in 1995 in the small village of Stråtjära, in Hälsingland, Sweden. She was christened Victor, but always knew that she was a girl trapped in the body of a boy - when asked age 3 what he wanted to be when grown up, she responded "A woman!".  Her family and the people of her home village accepted her transgenderism, and she began taking hormones at the age of 16 years, with her sex change operation planned for 2013, when she reached 18.  She moved to Stockholm to study fashion and dreams of a career as a model, and her ImVicky blog already has a huge following.

Doctors certainly seem to agree that giving - for example - a 13-year-old transsexual boy-to-girl doses of oestrogen will make her physically far more attractive as an adult woman.  However they also agonise about the possible negative consequences - and perhaps their potential legal liabilities from prescribing female hormone to "boys".

Young transsexuals often struggle to understand the medical "best practice" guidelines that affect their life.  Riley (pictured right, age 9) was when 12 diagnosed both oestrogen and testosterone blockers.  It was explained to her that this would make her body more feminine, her voice won't deepen and that she could eventually develop breasts - but that she would be infertile.  Her reaction was "But I can adopt babies ... why can't the doctors take my testicles off now?"

A rare example of the medical community responding to the needs of young transsexual may have achieved in Germany when it was revealed in 2007 that doctors had prescribed puberty blocking and later female hormones to a 12 year old 'Kim', formerly Tim.  At age two, Tim was trying on his older sister's clothes, playing with Barbie dolls and saying "I'm a girl."  By age four Tim was refusing to get to his hair cut and wanted to cut of his "thing", for the sake of a normal life his parents increasingly accepted their son Tim as being their daughter Kim.

Kim Petras age 13.  Born in August 1992, in 2008 she became famous as the world's youngest post-SRS transsexual at age 16. (Germany)

The situation reached a crisis when Kim grew increasingly distressed at becoming like other adult transsexuals with big hands and deep voices, whom she thought looked ridiculous when they dress like women.  Her father said "We saw Kim as a girl ... not as a problem. ... [she] reacted badly to the first signs of puberty... At that stage we realised that she was terrified of growing facial hair and her voice breaking".

Kim’s parents decided to help her get a sex change and consulted psychiatrists across Germany.  Some condemned their support of their child’s desire to undergo a sex change, or suggested that she be kept under observation in a closed psychiatric ward.  But Dr Bern Meyenburg, the head of a clinic for children and adolescents with identity disturbances at Frankfurt University, concluded that the child was serious. He wrote in his diagnosis: "Kim is a mentally well-developed child who appears happy and balanced. ‘There is no doubt of the determined wish, which was already detectable since early childhood. It would have been very wrong to let Kim grow up to be a man." 

A transgender group meeting at a university - in recent years "Transgendered" has finally been added to Gay, Lesbian & Bisexual.

Dr Meyenburg had once strongly opposed hormone treatment for children but changed his mind when one of his patients refused to listen and ordered hormones over the internet, then went abroad at 17 and had a sex change operation for a few thousand euros.  Dr Meyenburg admits that he was angry at the time, but said that today the woman is a law student and one of his happiest patients.  He now allows young patients to enter hormone treatment early, before puberty complicates a sex change. "They simply suffer less," he said, "it would have been a crime to let Kim grow up as a man".

Kim Petras, age 21

Dr Achim Wuesthof, who is now treating Kim at a clinic in Hamburg, said: "Imagine a man who suddenly starts growing breasts or a woman who starts growing a beard against their will – that is how Kim and people like her experience puberty."  Kim was thus prescribed female hormone therapy when just 12, and by age 14 was fully transitioned and living as a girl - with her identity and medical insurance cards changed to her new name and female sex.  German law only permits sex-assignment surgery (SRS) at age 18, but Kim apparently had this in November 2008 - just two months after her 16th birthday.  This created headlines around the world that proclaimed her to be the youngest person to ever have had SRS, although that claim is false - even excluding XY intersex children.  Just two examples are the sad case of David Reimer (age 22 months), and Victoria Beltran whose parents managed to get her surgery when just 15.  Also, hundreds of SRS procedures are performed every year on under-18's in Asia and South America, and it seems very likely that some are under 16.

Kim handled the intense media interests surrounding her surgery with great honesty and confidence, for example she told one interviewer "I was asked if I feel like a woman now - but the truth is I have always felt like a woman - I just ended up in the wrong body." Since age 18, Kim has concentrated on developing her a career as a singer.

The "Age 16 Passability Advantage"

Whilst the exact age can vary slightly, there does some to be huge divide in the ability of transgirls who began oestrogen treatment by age 16 to pass as female, compared to transwomen who started age 17 or later.  

The following table compares the effects of beginning female hormone treatment before a male puberty starts (which is typically age 12), with beginning treatment after male puberty has completed (i.e. after about age 17).  Extensive experience with intersex but "XY" female individuals indicates that for the very best results, low-level oestrogen treatment should be started at age 9, and stepped up to "puberty" levels at 12.

Commencing treatment during puberty will produce mixed results between the two poles - e.g. the voice may have already deepened irreversibly but facial hair growth is prevented or greatly reduced. 

Desired Characteristic

Pre-Puberty Hormone Treatment

Post-Puberty Hormone Treatment (Note 1)

Prevent skeletal masculinisation, e.g. large hands & feet; square jaw

Some benefit
(e.g. growth may terminate earlier, less heavy bones)


Modest height, e.g. less than 70 inches, 180 cm

Yes (note 4)


Broad female type pelvis 

Probably some benefit


Soft clear skin

Yes.  Also little or no acne during puberty.

Substantial improvement

Prevent facial beard hair


Little effect

Thick female type scalp hair and forehead hairline


Hair loss ceases, slight reversal of balding 

Female pubic hair pattern.  Hairless trunk and limbs. 


Substantial improvement after prolonged treatment 

Feminine type voice 

Yes for most children
(Prevents the dropping of the larynx, also known as the breaking of the voice)


No "Adams Apple"

Yes - little to none

No, surgery required.

Slim neck

Possibly a slight benefit due to skeletal changes

No effect that's not ascribable to dieting or surgery.

Minimise muscular development 
(Note 2)


Some reduction

Female type subcutaneous fat deposits and body contours (Note 2)


Variable redistribution. Increased fat deposits most significant on hips, buttocks & thighs after prolonged treatment

Reduced weight  (Note 2) No

May actually increase unless supported by dieting and exercise.

Small waist

Some benefit

May actually increase unless supported by dieting and exercise.

Full and mature "Tanner V" breast development  
(Note 3)

Substantial benefit
Breast development 1 or 2 cup sizes less than mother / sisters

Variable from slight to substantial breast development, Tanner V very unlikely. 

1.  Effects of hormone treatment vary considerably by individual and can take 2 to 5 years to fully achieve.  The longer after male puberty that female hormone therapy is started the less effective it will be - and the effects decline rapidly rather than on a linear scale.  E.g. results are considerably more dramatic with an 18 year old than a 28 year old, but not usually very different between a 38 year old and a 48 year old.  Other treatments can help feminise some characteristics in adult transsexuals.

2. Oestrogen hormones tend to deposit fat.  Sensible dieting and suitable exercising (e.g. aerobics, not power lifting!) will greatly assist and magnify the effects of hormones in developing a female type figure and body shape.  The objective should be a nicely rounded waist-hip ratio (WHR) of 0.7-0.8, a range which is a key visual "female indicator". 

3.  Breast development will vary considerably depending on the individual's genetic make-up and the time from puberty.  From hormones alone, a typical "natural" result in young transsexuals is one bra-cup size less than the girl's mother and sisters.

4.  Dr Stoker of the Boston Children's Hospital suggests that without hormone treatment one transgendered girl in the UK would have become 6ft 4in tall, rather than an acceptable 5ft 10in.  However excessive early oestrogen intake can also result in stunted growth and below average female height.

In June 2018, 17-year old reality television star Jazz Jennings celebrated her SRS by posting this photo with the caption "I have a vagina".  (USA)

Overall, the physical results of early hormonal treatment tend to be extremely successful, the girl developing a well feminised physique with full breasts (although rarely as large as the girl would like), no beard, plentiful scalp hair, and an unbroken female type voice.  It's less clear how much impact early treatment has on skeletal characteristics such as foot size and pelvic width.  For example pre-puberty, the  pelvis of boys and girls are indistinguishable, but post-puberty the female pelvis widens substantially.  This change is thought to be caused by estrogen, and studies of FTM  transboy's shows that hormone treatment suppressing estrogen and raising testosterone treatment can prevent this differentiation in transboys.  Oddly, there are no studies showing that conversely young transgirls taking estrogen, plus anti-androgens to suppress their testosterone levels, are likely to develop a wide, female-type pelvis.  Whilst this seems likely, the evidence is just anecdotal and medical studies are needed to prove significant skeletal changes rather than just fat redistribution.

Hormone Regimen's in Transsexual Girls
There seems to have been little published research with regard to the dosage for hormones in young transsexual patients, however research which relates primarily to Androgen Insensitivity Syndrome (AIS) patients is also probably applicable to transsexual girls.  Zachmann et al cite one AIS patient who had undergone orchiectomy in whom oestrogen administration was started at the earliest estimated pubertal age of 10.3 years in the form of Premarin 0.625 mg three times weekly.  It was found, however, that this stopped growth of the girl prematurely and the authors felt that it would have been better to have given the patient 0.005 - 0.01 mg ethinyloestradiol daily, instead.  From studies of patients with Turner syndrome it has been suggested that to ensure normal pubertal growth, physiologic oestrogen replacement should be started at the appropriate bone age of about 11 years and should not be delayed in the hope of achieving a greater mature height.  Batch et al suggest a regime of 5 micrograms of ethinyloestradiol daily for the first 6 months, increasing to 20 micrograms daily by the end of puberty.

Early hormone treatment is not a miracle, but the benefits such as female hair pattern, no beard growth, no Adams Apple, no broken (deep) voice, breast development are immense.
Soule et al. suggest that the best course of action may be to perform a orchiectomy just before puberty (at 11 years in a case quoted) followed by oestrogen therapy (ethinyloestradiol 2 micrograms daily, gradually increasing to 20 micrograms over 2 years, in the case quoted) with regular bone density measurements. This policy, it is suggested, reduces any slight risk of malignant transformation of the gonads and ensures adequate oestrogen activity throughout the critical years of bone accretion. 

Emma Ellingsen (born Tobias in September 2001) realised that she was transgender age 8 and began puberty blockers age 10.  In 2014 she appeared in the Norwegian TV show «Født i feil kropp»
(Born in the Wrong Body. Pictured age 17, she had SRS age 18. (Norway)

However, oestrogen levels are higher in XX girls than in XY boys, even in childhood.  XX girls start producing oestrogen at 8 or 9 (i.e. a year or two before breast development) so several clinicians therefore recommend early oestrogen supplements in XY girls, irrespective of whether or not the gonads are in place.  Dr. Stanhope suggests 1 microgram ethinyloestradiol per day from age 8-9, with an increase at about 11-12 years.

Females Hormones and Attractiveness
A very awkward problem for psychologists advocating delayed hormonal treatment for young transgirls is that as result they will be physically less attractive as a woman to men.

There is a strong and direct correlation between a girl's oestrogen levels during puberty and how attractive and feminine she is perceived as a woman.  For example, the hormone has lasting effects on bone growth and tissue formation as well as the skin’s appearance during the average seven-year-long puberty.  Miriam Law Smith of the University of St Andrews states the hormone has a hormone has a crucial role in determining facial appearance, giving 13-year-olds doses of oestrogen will "certainly may make them more attractive [to men]" although she adds "who knows what other effects the hormone may have?" As regards the last comment, pubertal girls who have been prescribed oestrogen to prevent excessive height (over 6 feet) may according to one study subsequently suffer from lower fertility. 

A contemporary of Emma is Siri Lehland.  He was born in February 2001 and identified as transgender by age 10.
She must have started female hormones by age 16 in order to explain the breast development evident by age 17.

Since the 1960's the medical professional has been puzzled why one child may determinedly transgender, whilst his/her brothers and sisters are equally determinedly cis-gender.  If as some leading medical practitioners were suggesting (most notably Dr John Money) external factors during childhood played a critical role in determining gender, it seemed reasonable to predict that if one child is transgender, there was a good probability that their siblings were as well.

The theory got some support when in 1970 two American half-sisters - Lauraine and Lenette - were outed as having been born Cary and Burt.  They transitioned together and Lorraine had SRS age 26, the younger Lenette had to wait another six months as the clinic refused to perform her surgery until she was 21.  They not only appeared in newspaper stories at the time, but were mentioned in many medical textbooks published the 1970's.

Unfortunately for some members of the medical profession, few - if any - transgender siblings appeared (at least publicly) during the 1970's and 1980's.

In 1993 French newspapers briefly covered the story of supposedly transgender sisters Dominique and Alix, born brothers Patrick and Yannick.  Patrick had  shocked his parents by announcing on his 18th birthday that she was a girl and wanted to be called Dominique, and allegedly had SRS.  A few years later her younger brother Yannick made a similar announcement and asked to now be called Alix.  But the newspapers fed the story were unable to obtain a picture that showed Alix as anything other than a rather effeminate looking 18-19 year old teenage boy.  Also, Alix's claimed boyfriend turned out to be a divorced 41 year-old who had two sons of similar age to Alix.  It all seemed decidedly dubious and the newspapers soon gave up on the story.

In 1996, two 20-something sisters Mi and Ana (right) featured on an American television talk show about close sisters. The twist eventually revealed to the audience was that they were born brothers, and were male-to-female transsexuals.  [I've tried to track down more details, but I've been unable to confirm anything.]

In the 21st century the transgender population has soared, and perhaps inevitably there has a emerged in to the public domain a few instances of two brothers becoming sisters.  For example, in February 2016, a 23 year-old barmaid working at The George pub in Cork - Jamie O’Herlihy - came out via a YouTube video as being transgender.  For several years she had worked as a drag queen at a gay bar but had transitioned to female and begun taking female hormones the previous November - retaining her androgynous first name.  The news attracted only mild interest until Closer magazine discovered that Jamie's younger 20-year old sister Chloe had been born Daniel. 

After a difficult final year at school as a boy, Chloe had quietly transitioned to female in the summer of 2015, before starting a college course to train as a hairdresser.  The story of the two transgender Irish sisters went viral, and they appeared in newspapers around the world, as well as on Irish television programmes such as This Morning and the Ray Darcy Show - often accompanied by their mother Sarah.  The money earned hopefully helped to pay for Jamie's facial feminisation surgery, and Chloe's SRS in 2019.

Almost simultaneously, another story concerning two American transgender sisters was unfolding.  In 2016 14-year old Matthew Whitley transitioned and became Madelyn ("Maddie") Whitley.  Her twin brother followed just a few months later, transitioning as Margo in January 2017.  Both Madelyn and Margo have since been signed by model agencies and now work with great success as female models.

In 2020, headlines were made when identical twins Mayla Rezende and Sofia Albuquerck (right) both had SRS/GRS.  Although they grew up as boys in the small town of Tapira in southwestern Brazil, they’ve always known they were girls.  Malya says “I would blow dandelion seeds into the air and wish for God to turn me into a girl, I always loved my body but I didn’t like my genitalia.”

On  11 and 12 February 2020 the 23 year old sisters received surgeries to affirm their gender identity. Dr. Jose Carlos Martins of the Transgender Center Brazil performed five-hour surgeries on the sisters one day apart. “This is the only reported case in the world of twins who were presumed to be male at birth undergoing female gender confirmation surgery together” the doctor claimed.

The global transgender community now numbers in the millions - compared to hundreds in the 1950's, thousands in the 1960's, and tens of thousands in the 1970's.   If the theories of Dr John Money et al are correct then there should now be a very large population of transgender siblings.  But there aren't, so their theories are incorrect.  Unfortunately this doesn't help us understand a situation where in the UK the ratio of children with gender identity disorders has in just two decades changed from 1 in 10,000's, to 1 in 100.

Passing and Sexual Orientation
There seem to have been no formal clinical studies, but it seems certain that young male-to-female women are far more likely to complete their transition and settle well into their new lives than those who transition at a later age. 

About 95% of natal "XX" women consider themselves as being heterosexual.  In comparison, studies of the sexual orientation of post-SRS transsexual women indicate that only half are heterosexual and exclusively select males as sexual partners; nearly one-fifth are lesbian and sexually attracted only to females; and about one-third are bisexual.  However these studies cover all age groups (with an average age in the 30's or even 40's), and are almost certainly not representative of the relatively few young transsexuals who transition before the completion their male puberty.  It is very likely that when compared to older transwomen, a far higher percentage of young transsexual women identify themselves as heterosexual and attracted to men.  Indeed, for under 21's, I would suggest that there are very few girls who do not consider themselves to be heterosexual, and have or would like to have, a boyfriend.

14 year old Jamie (left) and 15 year old Danique are unambiguously girls after their transition. (Netherlands)

Roberta Close (shown age 17) had numerous liaisons with male 'A list' celebrities after her SRS.

Unlike older transsexual women, young transsexual girls rarely have had any sexual activity before they transition, and if they do it's likely to be of a homosexual nature, generally playing a female role during intercourse.  Mentally they are often only erotically stimulated by men, although overall their sexual urges may be very low because of puberty suppressants.  When released from such drugs and placed on hormone therapy, they become just as interested in boys and men and sex as other girls of their age - if not more so.  "G", a nearly 16-year old transgirl undergoing an intense female puberty thanks to being on hormones illicitly obtained by her parents, may be quite typical when she writes:  "I can't stop thinking about my [neo-vagina] ... I want to be ['screwed'] by any guy in sight.  I was even thinking about my teachers and my best friend's dad."  But this girl does not expect to undergo SRS for years yet.

Hopefully G will be able to emulate Veronique Renard, who has happily led a very active love life as a woman since her teens.  She may have the youngest patient in Europe when she had SRS in 1984, but the resulting advantage was immense:

"I always felt part of a group called Females, my female penis [was] a birth defect ... I was only 17 when I started hormones. I had the big operation at 18. I never got to know what I would have been like as an adult male. As I was so young, I could experience life like my girlfriends. I got my first boyfriend at age 18 as a girl. I [have] experienced my entire adult life as a female."

Alina - in red - was born the brother of her cis-sister.  (Russia).

Unlike older transsexual women - young transsexual girls rarely have any problems passing easily and naturally as female, readily assimilate themselves as women.  For example, in one survey (Sex Reassignment of Adolescent Transsexuals: A Follow-up Study, Cohen, 1997) of young transsexuals, all the male-to-females were satisfied with their appearance after hormone therapy, and it was the interviewer's observation that it was difficult to discern any signs of their [genetic] sex.  Most of the girls had been approached in a flirtatious manner, and not one had been approached by strangers as if they were still of the male sex, 60% expressed satisfaction with their vaginoplasty, and had experienced sexual intercourse without problems.  The author of the study suggested that part of the adolescents' success was due to the fact that they more easily pass in the desired gender role because of their convincing appearance.  With one exception the voices of the girls were not male sounding, and early anti-androgen treatment apparently had acted in a timely way to block facial hair growth and the lowering of the voice.

Somewhat disputably, the study also stated: "Another aspect of this relatively positive outcome may be attributable to the criteria for treatment eligibility. ... [The] patients selected for early treatment not only are among the best-functioning applicants, but probably they also belong to the subtype of so-called "homosexual transsexuals" (that is, individuals who are, before SRS, sexually attracted to same-sex partners) .... They are also referred to as "primary" or "early-onset" transsexuals."

Nevertheless, success in passing may well be an important factor in young trans-girls being far more likely to have a heterosexual sexual orientation than transsexuals who transition as adults.  It's clear that trans-women who transition at a young age are almost always physically able to go stealth, they typically do as soon as possible, and often quickly begin to have boyfriends and eventually a husband.  The desire for a normal relationship with a man tends to pull the stealth transwoman away from any open acknowledgement of her transsexuality and male past, she believes (unfortunately often correctly) that the relationship may not survive this becoming known to him.   In the balance between personal happiness and revealing "the whole truth and nothing but the truth", most people choose happiness.  Based on anecdotal experience, when a young transwoman out's herself, most (but not all) soon regret.

These young transsexual women featured in the July 2002 edition of the UK magazine Marie Claire. 
Nina (second from left) was 22, Jamie (back, fourth from left) was 16, and Zoe (first from right) was 21.

Jenny Hiloudaki was born Yiannis in 1981.  He began secretly taking female hormones when just 13, and had Sex Reassignment Surgery age 20.  She was 'outed' at age 29, but two years later was voted 'Greek Woman of the Year'.

In the early 1990's
Deborah Davis had sex reassignment surgery at age 17.  Twenty years later it is still very rare for teenager's to be able to have such surgery.

Sex Re-assignment Surgery
After hormones and transition, the next and final step is sex-reassignment surgery.  Extra-ordinarily, only about 1% of SRS operations performed by western surgeons are on girls under age 20 (almost all of whom are 18 or 19).  The reasons seem to be a combination of the Standards of Care guidelines, the need for a two year real life test when a hormone supported transition can only begin no earlier than age 16, money, the requirement for parental permissions in some countries, the reluctance of surgeons to operate on very young transsexuals, and the extreme rarity of under-20 (or indeed under 25) surgery candidates compared with older candidates - the median average age of European transwomen at the time of their SRS is mid-to-late 30's, with a mean average age of around 40. 

Angel Paris-Jordan (formally Oliver Whedan) had SRS and breast implants when just age 17. (UK) 

By interesting contrast, one study of 195 Thai male-to-female transsexuals found that "many participants had transitioned very early in life, beginning to feel different to other males, and identifying as non-male by middle childhood. By adolescence many were living a transgendered life. Many took hormones, beginning to do so by a mean age of 16.3 years, and several from as early as 10 years. Many underwent surgeries of various kinds, on average in the twenties, with one undergoing SRS as early as 15 years".

Clair (formerly Alex) Farley told her parents that she was gay in when 13.  After a suicide attempt age 15 she told a councillor "I feel that I should be a girl".  She finally transitioned at age 18 and began hormones, over the next year: "My hips widened, my thighs thickened and tiny breasts started to appear".  She finally had her SRS at age 23, "a few days later I pulled out a hand mirror and got a first glimpse of my new vagina ... it was badly bruised but I couldn't have been more excited, I was all woman".

Another extraordinary tale of determination is Lucille.  Born in 1986 as Lucien, he knew even at pre-school that he was a girl, not a boy.  By secondary school his long hair and wearing of girl’s cloths led to teasing and worst.  He sought medical help but faced three year waiting lists.  After leaving school he obtained a job as a female hair dresser but lost it after being out'ed.  In desperation he persuaded a private medical clinic that he was from a noble family and had well-to-do parents.  In June 2006 - age 20 – the clinic performed sex reassignment surgery and breast augmentation on her.  Unfortunately Lucille couldn’t pay the clinic's  €18,000 bill and the subsequent court case made headlines in Austria and Germany.  Although sentenced to six months in jail, she had no regrets, saying “My suffering was enormous… I had finally become a woman because I am a woman.  I am a real woman.  I have a vagina, can experience orgasm.  [My breasts are also very important and] now I have 345 millilitres of silicone per breast.”  Happily the sentence was suspended and she eventually paid the bill.  Lucille married soon after her SRS and is now a successful artist.

Céline Van Den Bossche

Finally, whilst at primary school, Van Den Bossche knew that she was different from the other boys.  She began wearing make-up and dressing as a girl. When age 15 she transitioned with the name Celine and began a long process of change, involving psychologist appointments and hormone pills. Age just 18, she underwent a sex change operation and was legally a woman.  Four years later, whilst working as a hair dresser she entered and won a local beauty contest. As a result she qualified for the Miss Belgium contest.  As a favourite, she was interviewed by a reporter from Laatste Nieuw who had done some research, she said "Yes, I'm transgender, so what?"

If a transgirl has been determined in her identification as female from a very young age, then (as described above) there are many advantages in the prescription of puberty blockers and even female hormones by age 12.  One advantage would seem to be that the penis remains tiny (maybe an inch in length) and the testicles do not drop.  But this suppression of developing a male body actually creates a serious problem as most SRS procedures use scrotal and penile skin to create the neo-vagina, and there maybe simply not enough skin to do this. 

Another photo of Jazz Jennings age 18, note the scars from her surgeries.  She has exceptionally good breast development from only female hormone treatment.

A high profile example of this is the experience of American TV reality star Jazz Jennings, who grew up as a girl from age 5.  Going into her SRS age 17, her doctors were worried there wouldn't be enough tissue to reconstruct her genitalia because she had a puberty blocker inserted in her arm before puberty. As feared the procedure did not go well and she had serious complications (basically her shallow neo-vagina split open) which required another procedure a week later, with further surgery required.  She said in a video posted on her YouTube channel:

"I didn't have growth in that region and because there was a lack of tissue, they didn't have enough material to construct the vagina. So they're using a special procedure where they extract my peritoneum lining through my belly button and they use that and they harvest it and they use it to create a vaginal canal."

This surgery went quite well, but yet another corrective procedure was required to improve the external appearance of her clitoris and vulva area.

The Belgium model Maxim Magnus has had very similar problems to those experienced by Jazz.  She began female hormones at age 14 and had SRS in 2016 when age 18 but soon had major complications:

"One night, I was in the middle of dilating when I felt the most excruciating pain, and I began screaming and crying. By the next morning, I was back in for another surgery. The wound had basically ripped itself open"

She had recently been discovered as a model and was being hailed by the likes of Vogue as "Fashions next big star".  Instead she was forced to retire from modelling for a year.  In 2019 she posted "I’m about to have my fifth surgery in two and a half years to correct more issues related to my SRS [but] in spite of everything, I’m glad that I had SRS"

[Note: Articles and interviews about Maxim give her confusingly different ages, but the concensus seems to be that she was born on 15 April 1998.]

Parental Support - Changing the Rules
A positive reaction from their parents when a child comes out as out as trans is a huge support and the impact can’t be underestimated.  A supportive family can make huge difference to a  transperson’s mental well-being in the long-term, and their relationship with the rest of the family will be much more positive, in particular with the parents.  One supportive mother of a young transgirl said:

“When your kid presents to you exactly how they are, there’s no changing it, you just need to follow their lead on it.  And it doesn’t necessarily mean having of all the medical intervention that people are now so scared of with their kids for some reason – I think it’s just about letting your kid experiment and play around with who they are, and if they change their mind that’s fine but they just need to know that you love and support them.”

The active  support of their parents is also essential for transgirls when trying to find help at school or from the health system.  Considering all the advantages of the early treatment of the young transgender children, it's unsurprising that this is now increasingly demanded by  knowledgeable parents increasingly informed via the Internet.

The stories of young transsexuals are often very news worth.  Melanie McPryce (formerlyTom McGlone) transitioned at 16, started hormones at 17 and spent €22,000 to have sex-reassignment and breast augmentation surgery in Thailand the day after her 18th birthday. The 
News of the World newspaper gave her story a centre page spread and hopefully suitably recompensed Mel and her mum.

Parents are undoubtedly influencing a 'system' and medical profession that was in the 1990's retreating rapidly from early treatment and accommodation of young transsexuals.  After a decade long reaction to the tragic David Reimer affair, it has become recognised that it is necessary to separate and differentiate between the voluntary and non-voluntary gender reassignment of children.  While numbers are still small, there is nevertheless an increasingly willingness by doctors and the "system" to support and aid the early reassignment of children.  The revised guidelines in the current version 6 of the "Standards of Care" issued in 2001 makes it slightly easier for young transsexuals to officially obtain treatment - including puberty-delaying drugs but not female hormone therapy for those reaching their teens. 

But doctors still face circumstances where a failure to support young transsexuals in order to comply with guidelines can seem at best totally unreasonable.  For example, in 2006 a 5-year boy was allowed to enrol in kindergarten as a girl with a "gender-neutral name" in Florida, USA, having been diagnosed with gender identity dysphoria (GID) two years ago earlier.  The parents said the child refused to wear boy's clothing and repeatedly said she hated having a penis - often trying to hide it between her legs.  Officials said that were already a number of trans-students in the school system but none as young as kindergarten age, they expected that the youngster would go unnoticed as a girl.  Can she be denied female hormones at age 11-12?

Meanwhile, in Japan a 7 year old boy with GID, Ryoko Kanda, has been allowed to enrol as a girl at a school is in the prefecture of Hyogo, about 270 miles west of Tokyo after being diagnosed with gender identity disorder at age 6.  The school has not told other parents about the switch, and a spokesman for the local school board said there had not been any complaints from other students or from the boy's parents since his enrolment.  He stated that the boy's name is listed with girl students, she uses the girls' bathroom, attends a girls' gym class and wears a girl's swimsuit at the school pool.  The official also said "At this point, we are relieved that the child was accepted into [second] grade and is being raised in a healthy manner", he added that the school district would watch his case closely and reassess the decision as the boy reaches puberty.  Katsuki Harima, a psychiatrist specializing in gender identity disorder at Tokyo Musashino Hospital, said the decision to allow the boy to enrol as a girl seemed appropriate, but would get complicated as he grew older. Harima said the boy is not old enough to determine whether he really has the disorder. A boy who behaves like a girl does not necessarily have gender identity disorder and he could discover as he grows older that he wants to be male.

Although identified at birth as boy, Norwegian Siri Lehland always wanted to wear girls cloths and by age 10 she was adamant that she was female.  Her mother, Katja says:

"As parents we soon realized that this was not a phase that would pass. This is why we have always said that Siri was not born as a boy, but in a male body. As a mother I was always worried about how Siri would be treated as she grew up. We have had good people with us all the way. They have shown us respect"

With the strong support of her mother, Siri transitioned by age 12 and began to aspire to be a model.  Four years later she appeared on the front cover of the Norwegian edition of Elle magazine in 2018, still just 17, much to the delight of her proud mum! 

Progress since 2001
This article was first written in 2001, revisiting it a decade later there has been some progress in the treatment of young transsexuals.  There can be almost no doubt that a series of highly publicised transgender success stories - basically young boy-to-girls who thanks very substantially to early medical treatment look and sound like teenage girls - have helped this immensely. Another generally very positive development has been the appearance on social media such as YouTube, Facebook, Instagram and Twitter of openly transgender girls who then act as an inspiration and source of information for other girls

Openly transgender teenagers on social media include:-

Little by little an increasing number of clinics are now willing to help young transsexuals with medication and even surgery at an early age.  Two examples:

In 2017 the advocacy group Transilient selected this image of Carmen for "17 Photos Reveal The Realities Of The American Transgender Experience".  Although born in Mexico, she was
studying in Arkansas to become a Water Engineer.

USA: In 2007 the pediatric endocrinologist at the Children's Hospital Boston, Dr. Norman Spack, set up a clinic for pre-adolescent transgender children. Dr Spack uses drugs to delay the first stirrings of a youngsters' puberty, typically age 12 to 14 for a boy. The effects of these puberty-blocking drugs are reversible but is not the case with hormones. Dr Spack is flexible about the age he prescribes estrogen - i.e. he's not rigid that the child has to be age 16+, but will only do so after months of consultation with the patient and her parents.  He says "When kids take this step, they are rewriting their own future: The hormones have a powerful, pervasive effect, changing their height, breast development, and the pitch of their voices ... You have to explain to the patients that if they go ahead, they may not be able to have children. When you're talking to a 12-year-old, that's a heavy-duty conversation".

Matti, age 15 (UK)

UK: The Portman and Tavistock Clinic was established in North London to provide treatment to transgender children under the age of 16.  It was initially deemed controversial due to the patients' ages - with critics arguing that the youngsters lacked the ability to consent to the therapies.  However in the two years 2011 and 2012 the clinic received 142 referrals of children in the age group 11 to 15 from parents and carers.  Dr Polly Carmichael, director of the service, said it was "better for children not to have gone through puberty before transitioning". But she added: "You are asking someone aged as young as 11 to make big decisions about their adult life and identity. We have to be very careful to keep options open".

Perhaps the most important recent development is that the famous/notorious "Standards of Care for the Health of Transsexual, Transgender, and Gender-Nonconforming People" (which very few medical professionals will dare not to conform to) has now advanced a tiny bit as regards young transsexuals in its seventh edition, published in 2011.  It now allows the use of puberty-suppressing hormones - but only when puberty has already begun!  It also says that "Adolescents may be eligible to begin feminizing/masculinizing hormone therapy", essentially from age 16

Huge progress has undoubtedly been made in recent years in the treatment of transgender children.  Further the increasingly positive image presented about gender dysphasia in social media, in television programmes such as I am Jazz, Transparent and films's such as the Danish Girl has resulted in young children identifying themselves as being transgender in unprecedented numbers.  For example the number of under-18 children being referred to the Portman and Tavistock Clinic as having gender identity problems has been nearly doubling annually - in 2009/10 there were 97 referrals, by 2015/16 this had reached 1398.  Interestingly, the clinic now had twice as many girl-to-boy than boy-to-girl referrals.

Transgirls in the UK Media

Perhaps a sign of the progress that has been made in recent years in the United Kingdom are the stories of Campbell Kenneford and Maxine Heron.

Maxine Heron was born a born 1996, but she “always knew that I was a girl".  She came out age six to her mum when she refused to have her hair cut.  "I think it came as no surprise because as soon as I could start to express myself I would always do so in a way that was really female ...  I just was always kind of her daughter".  Her parents accepted her choice and with their support she had the courage to transition full time when she went to a College of Higher Education, age 16. 

Maxine, ages 12 to 22 (UK)

After she left college she had a variety of jobs, from receptionist to booking agent.  After having SRS (perhaps age 19) she began to work as model.  She was completely passable with a very feminine voice, an acceptable height of 171cm / 5´7" and slight weight 63 kg / 138 lbs, but in late 2018 she "decided to come out on social media and tell everybody about my history".  The response was very positive, e.g. one photographer who had booked her a few months earlier posted:

"As a straight, cis-male man, I am not often called to question my gender or sexuality. ... It was a privilege for me to be able to learn more about Maxine's experiences and share a brief creative moment with her.  Our conversation [made] me think about identity generally, and the secrets each of us keep: we all carry the burden of things unsaid."

Shortly afterwards the BBC booked Maxine for the reality TV series Heartbreak Holiday, where "Ten 20-somethings travel around Europe, attempt to get over their heartbreak and  get pretty loose and wild along the way".  The tagline for Maxine was that "After a string of bad, short-term relationships since she and her serious boyfriend broke up on New Year’s Eve in 2017, Maxine is looking to have her faith restored in men and her heart healed."

The series was shown in August 2019, in episode four Maxine unexpectedly stood up during a meal and revealed that she is transgender to her apparently genuinely shocked table mates.

First Day (Australia)

Another significant development in 2020 was the Children's BBC showing the Australian made First Day.  A short film was made in 2017 that followed the traumatic first day at High School of 12-year old Hannah Bradford, a boy who had transitioned to school girl.  Importantly, it starred 11/12-year old transgirl Evie MacDonald.  The film received so much critical success that a further 4 episode TV series was commissioned in 2019, following Hannah through the rest of her first year.  Evie again starred, although her two-year age difference from the original short is obvious.


A Warning

In 2018 the British media reported that one school had 19 children (2% of its roll) listed as transgender.  Subsequent reports claimed that about 1% of all school children were now identifying themselves as transgender.  These percentages were plausible given that about 40 times more children were being treated by the NHS for gender identity disorder (GID) than a decade earlier, the  Portman and Tavistock Clinic (mentioned above) had 2,590 children referred to it in 2018, compared with just 77 in 2008.

It seems that for good or bad a critical point has been reached where children (particularly in their early teens) are beginning to consciously choose their gender.  It is attention gaining and potentially even trendy for a 12-14 year old to proclaim that they are androgynous, transgender, non-binary, etc., with children encouraging each other to transition and request medical treatment such as puberty blockers (available on NHS from age 11 since 2011) and hormones (available from age 16, but increasingly prescribed at 15). 

In 2013 a controversial Dutch study was published, it followed 127 adolescents (79 boys, 48 girls) who were identified as having GID in childhood (<12 years of age). The researchers found that 80 (63%) of the children no longer considered themselves transgender by the ages of 15 and 16 - significantly higher percentage than other studies. However critics of the study note the researchers lost contact with 28 children and assumed that they were in the "no" column, an alternative possibility was that they had transitioned and gone stealth, which would nearly reverse the percentage!  

Young transgender actress Josie Talah posted on social media many photos of her 20th birthday with prominent LGBTQ+ friends.  This one shows her (right) with Harley Wittmer (left) and Landrey Bender (center).

Despite the diverse results of studies, its VERY important to note that many children who test their gender identify at a young age (3 - 10) will actually revert to their physical sex by puberty - VERY great care thus needs to be exercised by both parents and medical professionals to avoid irreversible decisions and medical actions at too young an age.  Although the incidence of GID referrals in young children below age 12  is exploding in number, the percentage that eventually have sex-reassignment surgery is actually declining - down to just 10% in the UK in 2015.  After therapy, transition and perhaps hormones, many decide that they have made a mistake, whilst others decide that whilst they wish to live as a woman, they don't want surgery.

19 year old Juliet Evancho was developing her career as a model when her sister - Jackie - sang the national anthem at the inauguration of Donald Trump as President in 2017.  She was out'ed in national media as  being Jackie's transgender brother/sister.

Conversely, children who begin questioning their gender at an older age seem far less likely to change their mind.  As puberty begins. it seems that almost every child who age 12+ begins blockers or hormones will eventually have surgery, and nearly zero later regrets.  For example, Jack Green started to show signs of GID as young as 3.  By age 9 his mother Susie was letting him dress as Jackie but by age 13 she was veryoncerned about both the resulting bulling and the onset of male puberty.  Puberty blockers were obtained from an American clinic and Jackie also referred to the Tavistock Clinic. 

In the UK transchildren under 18 are able to have gender confirmation surgery with their parents consent.  However the process by which young, trans people access such medical interventions is subject to additional safeguards and its unofficially estimated that in 2018 just 35 such procedures were performed privately or via the NHS - a tiny proportion of the children being identified as having GID. 

When it became clear that Jackie was unlikely to have surgery via the NHS for many years due to the long waiting list, Jackie's parents for arranged for her gender confirmation surgery to be performed in Thailand on her 16th birthday.  Her mother later saying: "Medical intervention is very important, especially for teenagers who are already in puberty.  It's absolutely vital. [Particularly] if you’ve got a child who's suicidal and self-harming because their body is changing against their will,"

From left to right: Jackie Green (born Jack) shown age 3; age 9; immediately after her SRS age 16; participating in the Miss England beauty contest age 18; a social media post age 20; and finally 25 year old Jackie with her mother Susie.

Susie's high-profile campaigning for the medical treatment of children suffering from GID extraordinarily led in 2019 to a journalist reporting her to the police for having "castrated her child".  No legal proceedings resulted.

Son, we need to talk ...

The NHS’s statistics show that the rate of regret around gender affirmation surgeries is very low but a small number of young patients do subsequently de-transitioned as an adult, and they then bitterly regretted having had irreversible 'bottom surgery' as a child.  [Unfortunately I have been unable to find even one quotable example of this.]  As a result, in April 2020 the UK government announced plans to ban all gender confirmation surgery on under 18's.  Dr Jane Hamlin, President of the Beaumont Society, a transgender support group, generally supported the decision, stating:

“It is important that those young people who identify as trans should have puberty blockers available to them if they are able to make an informed decision, have the appropriate medical support and there are no underlying health issues that would make this intervention unwise.  This would mean that decisions about irreversible surgery would not need to be considered until the individual has reached adulthood.”

In practice, most of those 35 operations will now happen outside the UK, predominantly in Thailand - as a far large number already do.

It's difficult to over-exaggerate just how great the advantages of early medical treatment are for the pubescent transgender girl whose body will otherwise rapidly turn in to that of a man, and how much of a disaster each month of delay is.  The end of puberty is a fundamental and irreversible physical marker, from which the plausible effects of feminizing hormonal treatments on the body of a transgirl/woman decline with depressingly rapid speed.  For any transsexual woman starting treatment when already physically mature (and this merely means age 20 onwards), a muscular and robust stature; a deep and masculine sounding voice; obvious facial beard growth; and a receding hairline, are just four of the immediate challenges that may seriously threaten her ability to pass convincingly as a woman.  She also faces the high cost of electrolysis, breast augmentation, facial feminisation, and other risky procedures such as voice feminisation surgery that could have been avoided

There is no longer any debate that for the best possible final outcome, the medical treatment of a male-to-female boy/girl with GID should be started as early as possible - ideally before puberty.  Decades of slowly accumulated empirical evidence seems to indicate that age 12 or 13 (depending on the individual) is the optimum age for a successfully transitioned transgirl to commence high dose hormonal treatment.

Puberty blockers are a poor second choice, but still far better than nothing.  When compared with the experiences of older transsexuals, the results of early hormonal treatment are dramatically positive.  It is however important that the girl has already successfully transitioned - this is a key point at which some young boys realise that are making a terrible mistake. 

Gender Clinics are reporting a near 100% success rate for children who transition, begin hormones and have SRS surgery in the age 16-18 window. Almost all successfully these teenage transgirls identify totally with their female gender and appearance, passing well both psychologically, socially and physically; they are far happier as a female and have no regrets.  They still face long term problems as being infertile as a woman, and how to tell this to a fiancée ... but these are a totally different set of problems from that which delaying medical treatment would have imposed upon her - such as an inability to pass due her beard, deep voice, and bald patch. 

The Cohen study mentioned above concluded: "Even adolescent applicants who are functioning well will need a lot of guidance through the process of sex reassignment. However, provided they manage to pass SRS without problems, they have a lot to gain.  They can catch up with their peers and devote their attention to friendships, partnership, and career."

It is unfortunate that the medical profession is advancing so very slowly, partially due to a lack of facilities and specialists.  In the UK only one NHS Gender Identity Clinic, the Portman and Tavistock Clinic in London, is able to offer specialist psychiatric and endocrinology services for transsexual children - and this for a population of over 60 million people!  

There is a valid argument that if medical treatment was not provided to transgirls, some would successfully revert to a male gender.  But it equally seems that many would resort to extreme measures, even suicide.

Finally, we appear to be heading to a world where a substantial proportion of the population will live most of their life in a gender that does not align to their genetic sex.  In the UK less than 1 in 10,000 children under age 18 were identified as transgender in 2000, twenty year later we seem to be in the situation where about 1 in a 100 children consider themselves as being transgender, increasing to 3 in 100 if we include those who identify as asexual, pansexual or gender fluid.

This has huge implications in terms of reproduction, and the normalisation families where one or both of the parents is transgender.  In 2019 nearly 10% of British babies are born using the IVF procedures pioneered over 40 years ago in 1978.  In another 40 years it possible to envisage that a similar proportion of children will have a transgender mother or father, and have been gestated and born using the various medical procedures that are now just being realised.

Warning:  Some of the hormone regimes stated below seem to be excessively high, overdosing on hormones will not have any additional physical feminisation effects but does have very serious and dangerous health risks.  Hormones should only be prescribed and taken under qualified professional supervision.
