Transsexual Women
and Female Sports

 

Note: This page assumes that a reasonable definition of sport is a "competitive physical activity".

The Problem

Genetically "XY" men are on average bigger, stronger and faster than genetically "XX" women due to their many physical differences.  As a result men tend to be significantly better than women at sports, as demonstrated by the following 2014 world records:

Event Men's World Record Women's World Record
100m 9.58 seconds 10.49 secs
800m 1 minute 40.91 secs 1min 53.28 secs
10,000m 26 mins 17.53 secs 29 mins 31.78 secs
Marathon 2 hours, 2 mins 57 secs 2 hrs 15 mins 25 secs
Javelin 98.48m 72.28m
Long jump 8.95m 7.52m

These records show that men have about a 11% advantage in running events, and significantly more than that others events such as the Javelin where muscular strength combined with a large skeleton is key. 

The presence and physical impact on muscular strength of the "male" hormone testostertone is accepted as being the primary cause of the disparity betewen men and women in sports.  An adult biological female will have just 0.5-2.5 nanomoles of testosterone per liter of blood, while a biological male will have 10-35.  The effect is amplified if a high level of testosterone is present whilst the skeleton is still growing - the impact of this on teenage boys is beyond dispute.  Due to the comnbination of genetics and hormones, a large percentage of men can beat the very best woman in sporting events that require physical size, strength and stamina. 

Since 1930's questions have been raised (sometimes justifiably) regarding the "femininity" of some highly successful female competitors.  Intrusive visual inspections began to be used to detect male impostors at major sporting events, but from 1968 these were replaced by various tests that verified a female competitors physiological sex by not detecting the presence of either a "male" XY chromosomal pattern or a Y gene. 

Whilst the introduction of genetics based testing for female athletes seemed to make a lot of sense at the time, it unfortunately soon became clear that the majority of the "fails" were athletes who due to a medical disorder had a Y chromosone but were otherwise undoubtedly female in both gender and secondary sexual characteristics.  Failing the "sex test" was a traumatic event for some of these women.

Sport and Transwomen
Since the 1970's discrimination against male-to-female (MTF) transsexual women has become increasingly unacceptable - both legally and socially. 

It seems reasonable that if a MTF transsexual is living as woman, is legally a woman, has a passport stating 'sex: female', and is married as a woman - that she should be able to compete in sports as a woman.  But some people - even some transsexual women - have severe reservations about the fairness of allowing this.  For example, if the world record holder of the men's 100 metres race had a sex change and two years later set a new world record as a woman - should that really count?  The closest known example of this happening is when in 1975 a 6 ft 2 inches tall, 40 year old, an American eye surgeon and amateur tennis player called Dr Richard Raskind had SRS and became Renée Richards.  After a legal fight, in 1977 she won the right to compete in women's professional tennis.  In 1978 she reached the women's quarter-finals of the US Open tennis championship and in February 1979 - at the amazing age of 44 - was ranked the 20th best female tennis player in the world.  Even Renée subsequently expressed doubts about the fairness of this.

Another factor - if rarely openly mentioned - is that women's sport has become financially very lucrative.  For example the Ladies European tour offers prize money of over €11 million a year, the USA tour about five times that.  Top 10 female competitors in sports such as tennis, golf and athletics can now earn more than $1 million a year in prize money and sponsorship deals.  A man ranked 250 - 1000 in these sports will barely earn enough to pay his expenses, but as a woman can earn far more.  Denmark born golfer Mianne Bagger is sometimes (very unfairly) quoted as example of the potential problem.  After moving to Australia she had SRS age 19 and subsequently never hid the fact that she was transgender as she progressed from an amateur golfer to becoming a professional female golfer in 2003.  She then had considerable sporting success, and was the first openly transgender woman to compete in top ranking events such as the Women's British Open and the US Women's Open.  Canny investment of her prize money has resulted her being worth $82 million in 2019!

Woman's sporting associations are desperately trying to develop rules that on the one hand are fair (and legal) in allowing male-to-female transsexuals and genetically 'XY male' intersex individuals to compete as women, but on the other prevent men or transsexuals with excessive physical advantages competing as women.  I.e. they are trying to square the circle!


It's Physical
Experts have been saying that women are rapidly closing the performance gap on men in sports, and some studies even optimistically claim that women could overtake them in the future (e.g. "Will Women Soon Outrun Men?" by Brian Whipp and Susan Ward, Nature, 1992).  But the the brutal reality is most men are still taller, heavier, faster, stronger, bigger, and more powerful than most women, and are likely to remain so.  A controversial study in 1997 by Seiler and Sailer published in Sportscience News found a male-female performance difference of 11-12 percent.  But the table of World Record's given in table at the top of this page has very similar differences.

Upon investigation, the difference in performance is best explainable by the substantial list of physical differences between men and women - even if we only consider factors directly related to sports.

Males typically have greater bone strength and density, greater muscle bulk and broadness in the shoulder area, and greater subcutaneous fat in the upper half of the body.  At maturity, females are generally shorter in height, have more flexibility in their joints, have more delicate ligaments and tendons, have more subcutaneous fat in the hips and lower body regions, have less erythrocyte and haemoglobin mass (which directly affects the ability to of the blood to carry oxygen and get rid of carbon dioxide), and exhibit a greater degree of pelvic tilt and obliquity.  The female elbow offers a greater carrying angle and tendency toward cubitus valgus (i.e. the lower arms stick out more), and the female has smaller lungs, heart, liver, and kidneys than the male.  Female joints are more subject to injury in sports requiring an expulsive effort, sudden stopping, sudden checking of speed and turns, and landing in jumps.  These differences are partly to the man's X chromosome, and partly due to the fact from about age 13 the bodies of boys are powerfully influenced and "masculinised" by a flood of testosterone from their gonads, while simultaneously the growth of girls is actually limited and "feminised" in a more delicate direction by the flood of oestrogen's from their ovaries.

According to a US Army manual:

  • The average 18-year-old man is 70.2 inches tall, the average woman of the same age is 64.4 inches tall - a difference of 9%.

  • The average 18-year-old man weighs 144.8 pounds, the average woman of the same age weighs 126.6 pounds - a difference of 14%.

  • The difference in physical size affects the absolute amount of physical work that can be performed by men and women.

  • Men have 50 percent greater total muscle mass, based on weight, than do women.

  • A woman who is the same size as her male counterpart is generally only 80 percent as strong. Therefore, men usually have an advantage in strength, speed, and power over women.

  • Women carry about 10% points more body fat than do men of the same age.

  • Because the centre of gravity is lower in women than in men, women must overcome more resistance in activities that require movement of the lower body.

  • Women have less bone mass than men, but their pelvic structure is wider. This difference gives men an advantage in running efficiency.

  • The average woman's heart is 25 percent smaller than the average man's.

  • For any given work rate, most women will become fatigued sooner than men.

  • The lung capacity of men is 25 to 30 percent greater than that of women. This gives men an advantage in the processing of oxygen and in doing aerobic work such as running.

What the Army study does not really emphasise directly is the fact that the "typical" young untrained male has an absolute oxygen intake (termed VO2 max) of 3.5 litres/min, while the typical same-age female has about 2 litres/min - a 43% difference which translates in to reduced performance and increased fatigue.  The difference reduces to 15 to 20% when the difference in body weight is allowed for, but is not eliminated. 

Part of the reason for the V02max difference is that the male sex hormone testosterone promotes the production of haemoglobin, an oxygen-carrying protein found inside red blood cells, and testosterone also increases the concentration of red cells in the blood.  The female hormone oestrogen has no such effect.  As a result, each litre of male blood contains about 150-160 grams of haemoglobin, compared to only 130-140 grams for females.  The bottom line is that each 'male' litre of blood can carry about 11% more oxygen than a similar quantity of female blood.

If we compare average body fat in males and females, we find the other part of the answer. Young untrained women average about 25% body fat compared to 15% in young men.  If we factor out body composition differences by dividing VO2 by lean body mass (bodyweight minus estimated fat weight) the difference in maximal O2 consumption decreases to perhaps 7-10% - close enough to 11% difference in blood carrying capacity just calculated.  But this is a theoretical paper exercise as a female athlete cannot reduce her body fat down to the sub 7% levels often observed in elite males without severe consequences to her health that would soon rule her out of competition anyway.

 

The Physical Advantage of Transwomen

The table below shows the relative advantage that a genetically XY transsexual woman may have in sports over a genetically XX cis-woman.  It is rather speculative, but is supported by the limited research available.  For example one study found that androgen deprivation in MTF transsexuals increases the overlap in muscle mass with women but does not reverse it.

Fallon Fox became a focus of opposition to transwomen competing in women's sports after her success as a mixed martial artist.  However she is just 5 ft 7 in (1.70 m) tall and weighs only 144 lb (65 kg)

However a counter view is that transsexual women who have SRS after puberty are actually at a disadvantage in many sports compared with other women as they are lugging around the large and heavy skeleton of a man without the compensations such as big muscles.  Dr Alison Carlson of the University of California aiyssts :

"A man who's castrated and takes oestrogen therapy loses a lot of strength advantages" ...  With someone like Renee Richards, she didn't suddenly become this winning player on the women's [tennis] circuit.  In fact, she didn't do that well, because although she was tall, she actually had female musculature being carried around on a large male skeleton.  It weakened her." 

Personally I'm not quite sure that the overall balance and weighting of advantages and disadvantages of adult transwomen agree with this view - although it does depend on the sport (e.g. weight lifting vs. rhythmic gymnastics).  More importantly, Renee Richards now believes (see below) that she did have a physical advantage as a transwoman playing against CIS-women.

Complete AIS is sometimes presented as the ultimate form of male-to-female transsexual - the suffer is genetically male XY but has a completely normal female body (albeit lacking internal reproductive structures) due to the total inability of their bodies to use the male androgen hormones produced by their testes in anyway, including for muscle development or VO2max.   However, a very interesting paper, "Complete Androgen Insensitivity "Syndrome": A Model For Human Performance in Sports," does not fully support the view that AIS women - or indirectly male to female transsexuals - have no advantage in women sports.

 

Sex Testing
As described above, a man competing as a woman would in many sports have arguably an unfair advantage.   It is possible that ever since competitive sports began there have been suspicions that some of the female competitors were not actually women - but the reality is that female sporting events weren't considered very important until the 20th century. 


Stella Walsh (left) and Dora Ratjen

The potential scale of the men-competing-as-women problem first became apparent after the 1932 and 1936 Olympic Games. 

At the 1932 Olympics the Polish sprinter Stanisllawa Walasiewicz (later Stella Walsh) was the winner of the women's 100-meters , but the IOC recovered her medals after learning that she had male reproductive organs. A post-mortem in 1980 revealed that she had male genitalia as a result of a rare genetic condition called mosaicism. 

Even worse, the German high jumper Dora Ratjen came fourth in the 1936 games.  In 1938 it emerged that "she" was actually a transvestite man called Hermann Ratjen, and unlike Stella he/she had no medical condition as explanation.  The IOC was further worried to learn that three other track-and-field champions who competed as females in the pre-WW2 games eventually underwent reconstructive surgery to remove external, male-like reproductive structures.

After WW2, sport became increasingly super-power politics by other means.  The masculine physique, deep voices and facial stubble of some formidable Eastern bloc "female" competitors became impossible to ignore, and after the 1964 Olympic games. it was decided to introduce sex tests.

Sex testing officially began at the 1966 European Athletics Championships in Budapest.  This was a simple visual exercise - women competitors were required to disrobe so that medical staff could "peak and poke" their genitals to decide whether they were indeed a woman.  Of course, many female competitors found this offensive, but it was also quickly obvious that several dozen athletes were not attending events where sex testing was being conducted.  The most prominent absentees were the Press sisters Tamara and Irina from the Soviet Union - who between them won five Olympic titles in the shot-put and hurdles respectively in the early 1960's.

Tamara PressThe quality of sex reassignment surgery (SRS) was rapidly advancing and it was quickly realised that after SRS a former man could pass the "peak and poke" test as a woman.  Therefore the far more sophisticated polymerase chain reaction (PCR) buccal smear test was introduced to examine the competitors chromosomes - with the blunt rule that if they weren't XX she couldn't compete as a woman.  Ewa Klubukowska, a 1964 sprint bronze medalist for Poland, had the dubious honour of being in 1967 the first woman to fail the sex test on account of possessing an XXY chromosome pattern, although she was clearly female in every other way.  "I know what I am and how I feel" she said at the time.  Soon after Ewa failed her "female" sex test she became pregnant and in 1968 gave birth to a healthy boy.  However, on on the other side of the coin Austrian skier Erika Schinegger (Women's World Downhill Champion in 1966) decided to become Erik after failing her sex test and later fathered a daughter.  Ewa and Erika were in crowded company at the time, as many other female athletes, including five British athletes, failed the new sex test in its early days. 

 

The AIS Conundrum


In 1983 Maria Patino passed a sex test as female and was given this certificate.
 

The 1968 Olympics was the first to require sex testing, and from the start the fairness of this gender verification test was hotly disputed as the vast majority of the women who failed suffered from Complete AIS (CAIS).  They had a female birth certificate so were legally female, and regard themselves as women.  Whilst pumping women athletics full of male hormones was almost certainly a common practice in the Soviet block until this date, it wouldn't work with an AIS woman.  "It’s sheer lunacy to think that an AIS woman has an advantage in sports," explains Sherri Groveman, who helps runs an AIS and intersex support group "In fact, we’re somewhat at a disadvantage.  I could be taking steroids all day long, and unlike other women I wouldn’t develop increased muscle mass.  My body can’t respond to androgens."


Maria Patino in 1989, after she was allowed to again compete as a woman.

Things came to a head with the Spanish hurdler Maria Jose Martinez Patino She suffered from AIS, i.e. had male XY genes, but in 1983 she mistakenly passed a sex test and was certified as XX female.  However the 24-year old was retested when she entered the 1985 World University Games in Kobe, Japan.  On the way to her first race, she was told that she was genetically male and should fake an injury and withdraw (apparently a common practice when a sex test was failed) - if she didn’t it would be leaked to the press that she was a man.  She didn’t back down and she won her race.  The next day, her story was front page news.  She returned to Spain to be stripped of her titles and lost her university scholarship and her boyfriend.  Patino told a reporter “I knew I was a woman in the eyes of medicine, God, and, most of all, in my own eyes ... If I hadn’t been an athlete, my femininity would never have been questioned". 

Between 1972 and 1984, thirteen women "failed" the Olympics' chromosome test and were barred from competing.  Like Maria Patina, the vast majority were still women that suffered from partial or complete Androgen Insensitivity SyndromeThe Olympic Games Organising Committee started to face huge pressure from all sources because of the obvious mistakes (so called "false positives") that were being made in relation to sex testing, which potentially ruined the lives and careers of some women athletes.  Exemptions began to be made, starting in the 1988 games with Maria Patino herself.


Erika Coimbra, she competed in the 2000 and 2004 Olympics


Sarah Gronert 

However genetic testing continued, and this still affected many female athletes:

  • In the 1988 Summer Olympics in Seoul an unnamed top women's tennis player was prevented from competing when her AIS condition was identified. 

  • In the 1992 Olympics in Barcelona 5 out of 2,406 women tested as genetically "male", all with some form of AIS. 

  • In the 1996 Olympics in Atlanta 8 women out of 3387 didn't pass as female - 4 with cAIS, 3 with pAIS and 1 with another condition (5-alpha-reductase deficiency).  6 of the 8 had had surgery to remove their gonads.  All were allowed to compete. 

Between 1972 and 1990, one in every 504 elite female athletes was found ineligible as a result of sex chromatin testing yet not one was found to be a "normal male".  This statistic is still interesting as almost all disqualified athletes suffered from AIS, but only about 1 in 3500 women suffer from the syndrome, i.e. a genetically XY woman with AIS is roughly seven times more likely to become an elite athlete than an XX cis-woman.

If AIS women do have any physical advantage in sports then it probably lies in the fact they often tend to be taller and their skeleton closer to male than female in structure, although their musculature and body fat distribution is always typically female. For example Sarah Gronert - who has AIS and had genital surgery age 19 - lacks the robust skeletal frame and muscular appearance induced by decades of testosterone that caused Renee Richards so many problems in the 1970's.  However, and unsurprisingly, Sarah's best world ranking on the women's tour was 164 (age 26) whilst Renee reached 20 (age 46).  There's considerable competitive interest in this association as it has been suggested that Complete AIS represents a valuable model for female performance in sports. [Without wanting to argue with Ms Groveman, the author of this article does wonder if this skeletal advantage explains at least some the exceptional success of AIS women in the sporting field.   For example, it appears that the average AIS woman is the top 10% of the overall female population in terms of height, is it then only a co-incidence that AIS women over succeed at the top level of women's sports by a factor of 10?]

By the early 1990's the whole costly process of sex testing was becoming far more trouble than it was worth as it had become obvious that blatant cheats (i.e. a man with out surgery trying to compete as a woman) could be easily picked up by other means.  The vast majority of failures to pass the "sex test" were still due to AIS and no one was now arguing that AIS women were not women, so in effect most of the results were effectively false positives.  It was clear the effects of illegal performance enhancing drugs such as steroids and testosterone on the genetically XX female body were far more significant than an athlete suffering from AIS.

Finally in February 1999, the Athletes' Commission of the International Olympics Committee urged its parent organization to do away with sex analysis entirely and rely instead on observed urination during drug testing to pinpoint any obvious male impostors. 

 

A New Era

Erika Coimbra
Erika Coimbra at the Sydney Olympics.

Mandatory sex testing for women was abandoned for the 2000 Sydney Olympics, but this arguably led the media to search hard for examples of competing female athletes who may have failed the test.

Considerable press coverage was given to two Brazilian women - Judo competitor Edinanci Silva and volleyballer Erika Coimbra - when it was leaked to the press that both were born hermaphrodites, with non-functioning male genitalia which had been surgically removed.  It was confirmed by the IOC that both suffered from AIS and were eligible to compete as women, but sadly spectators and even some of their opponents made it known that they were unhappy about this fact.  The attractive looking Erika (age 20, weight 64kg, height 180cm, with long blond hair) received far less abuse than the much plainer looking Edinanci (age 24, weight 71kg, height 175cm), whose opponents disgracefully started to refer to as "he". 

Although "gender verification test was dropped before the the 2000 Olympics, there remained a question outstanding about whether sex-reassigned individuals could compete in their new sex.

In February 2004 an  IOC advisory group recommended that individuals undergoing sex reassignment after puberty could compete in the Olympics, but only under certain conditions:

  • Surgical changes must have been completed, including external genitalia changes and removal of gonads.

  • Legal recognition of their assigned sex must have been conferred by appropriate official authorities.

  • Hormone therapy -- for the assigned sex -- must have been given for long enough to minimize any gender-related advantages in sport competitions, a period that must be at least two years after gonadectomy.

On Monday, 17 May 17 2004 the International Olympic Committee announced  - albeit with some mixed reactions - that it was dropping all sex testing for woman's sports Transsexuals passing the prescribed conditions were also cleared to compete in the Olympics by the IOC Executive Board.  The  IOC spokeswoman Giselle Davies said the situation of transsexuals competing in high-level sports was "rare but becoming more common."  IOC medical director Patrick Schamasch said no specific sports had been singled out by the ruling.  "Any sport may be touched by this problem," he said. "Until now, we didn't have any rules or regulations. We needed to establish some sort of policy."

The decision, which covered both male-to-female and female-to-male cases, went into effect starting with the Athens Olympics in August 2004.  The new rules allowed the classification as female all men who had undergone a SRS operation, regardless of whether this was before or after their puberty.

The decision of the IOC to let transsexual women compete as female athletes, and a similar  decision by the International Athletics Association (IAA) seemed to usher in a new era.  There was no doubt that some Olympic events (e.g. running, javelin, pole vault, marshal arts ...) and many professional, semi-professional women's sports such as tennis, golf, football (soccer), basketball, bowling, running et al seemed to face a gradual influx of top ranked women who were transsexual.

Michelle Dumaresq became an early example of the apparent future.  After her sex-reassignment surgery in 1995 she claims to have lost bone density, three inches of height [which is extremely unlikely], and 30% of her muscle mass along with her testosterone, but nevertheless she still became the Canadian women's downhill cycling champ in 2002 - just a year after entering the sport. 

Renee Richards (who has some regrets about her own transition and SRS) believes that it all comes down to fairness.  Renee would bar transsexuals from women's sports if they were in their 20s and still had muscular male physiques that gave them an advantage over other women:

"That's why we have junior events and senior events, men's events and women's events, and why 130-pound fighters don't fight against 180-pound fighters.  We have categories in sports to have level playing fields.  Tiger Woods or Jimmy Connors or John McEnroe, if they're 25 years old and they have a sex change and within the next five years they go out to play against women, of course they have a great advantage.  

Renee also warned that unscrupulous male competitors could use the IOC's 2004 rules to give them more chance of success, albeit by competing in women's events.

"It's ironic that everyone has tried so hard to keep a level playing field - from corked bats to doping - but now the IOC has come up with a decision that defies fairness in a similar vein.  Sex-reassignment surgery is based on putting materials into your body."

Putting things in a UK context, the new reality was that Tim Henman could become Tina Henman and probably thus become a [female] Wimbledon champion at last.  With Henman’s strength and speed, height and muscle density, added to his skills, it would be a near certainty even after a year of female hormones and aging.

A counterview to Renee is offered by Alisha Kia Siadeski (formerly Paul), a trangender 'cowgirl' whose title winning passion is barrel-racing - a minor women-only sport.  She says: "I'm 5'5" and weigh 112 pounds - I have no strength advantage, never did ...  half the women I compete against are bigger and stronger than I am".   

Indeed, in 2007 Renee herself argued against the theory that desperate athletes will do anything to win the gold, even change their gender.

"How hungry for tennis success must you be to have your penis chopped off in pursuit of it? .... It's unlikely there will be a rush of men ... switching sex to clean up on the women's tour. Those fears are silly"

The Woman's Tennis Association (WTA) has led other sporting organisations in its acceptance of post-operative male-to-female transsexuals and hermaphrodites born with male genitalia - despite the doubts of some of its members.  As well as Renee Richards, publicized cases include (from left to right) Samantha Stosur, Sarah Gronert and Andrea Paredes von Roth. The muscular physique of Samantha has led to a renewed debate in Women's tennis about whether transwomen should be allowed to compete, with Martina Navratilova among those to express reservations.

 

Caster Semenya

There was no rush by male athletes to compete as a woman and it began to seem that sporting world had reached a generally acceptable compromise ... and then Caster Semenya burst onto the scene.


Doubts Begin To Return

A junior champion in 2008, the South African teenager took seven seconds off her personal best for 800m over the next nine months, breaking the South African record and setting a world-leading time in the process. The International Association of Athletics Federations (IAAF) felt "obliged to investigate", if only to rule out doping.  Hours before the start of the 800m final at the 2009 World Athletics Championships - a race Semenya would win by a huge margin - it was leaked that the sport's governing body had also asked for a gender test. The findings of the test were never released but she was cleared to compete again in women's athletics.   However CIS-female athletes increasingly complained that Caster had an "unfair advantage" over them. 

This triggered renewed reservations at governing bodies such as the IOC as to the extent to which women's sports should be open to transwomen.  The reservations focussed on androgenic hormones - the best known being testosterone which helps to form male characteristics such as strong muscles (except in AIS women). 

An IAAF working group, in conjunction with the IOC's Medical Commission, decided that female athletes with more than 10 nanomoles of Testosterone per litre (nmol/L) of blood would be bared from competition unless there were "reasonable grounds" for an exemption.  The AIS condition being an example. 

In April 2011, the new rules came into force. From this moment on, a confidential investigation could be made into any athlete where there were "reasonable grounds". This could be a complaint from a rival, or as a result of an anomaly in a drugs test.

Caster passed the revised tests and was able to compete as a woman at the Olympics, indeed she was chosen to carry her country's flag during the opening ceremony of the 2012 Summer Olympics in London.   Caster easily won the women's 800 metres races at both the London 2012 and Rio 2016 Olympics.  

 
Former male Olympic decathlon champion Bruce Jenner reappeared as female Caitlyn Jenner in 2015

Acceptance of Trans-Athletes

In the London Olympics of 2012, four female athletes with AIS were identified and allowed to compete - as had now become the long accepted norm.  The OIC also allowed an unnamed transgender/intersex athlete to compete as a female gymnast, however it bared transwoman Keelin Godsey from representing the USA in the women’s hammer throwing competition.

In January 2016 the International Olympic Committee issued recommendations that transgender athletes should be allowed to compete at the 2016 Rio Olympics without undergoing sex reassignment surgery.  Male-to-female transsexual athletes would only need to prove that their testosterone level had been below a cut-off point (set at 10 nmol/L per litre) for at least one year before their first competition.

The new guidelines - which the IOC claimed had been brought in to adapt to current scientific, social and legal attitudes on transgender issues - were not fixed rules or regulations but were instead designed as recommendations for international sports federations to follow.  

Former IOC medical commission chairman Arne Ljungqvist, who was among the experts involved in drafting the new guidelines, said:

"It has become much more of a social issue than in the past.  We had to review and look into this from a new angle. We needed to adapt to the modern legislation around the world. We felt we cannot impose a surgery if that is no longer a legal requirement."

Under the previous IOC guidelines of 2004, athletes who transitioned from male to female or vice versa were required to have reassignment surgery followed by at least two years of hormone therapy in order to be eligible to compete in their reassigned sex.  

The 2016 Olympics saw widespread claims that the Hungarian swimmer Zsuzsanna Jakabos was transsexual, but this was a fake news story - she had passed numerous sex tests since first appearing in the 2004 Olympics.  A report in the the Daily Mail newspaper that two British female athletes in the country's 2016 Olympics team were transgender was undermined by a complete lack of detail. 

Chloe Psyche Anderson is transgender and played women's volleyball in the USA at college level.  By 2017 she had been on female hormone therapy for five years, which had reduced her testosterone level's below even female norms.  She was still pre-SRS when she wrote in May 2017:

"I never doubted I could be an athlete and transition. I just had to do extensive research prior to make sure I fit into the associations legally, but my body and I have had a long and frustrating relationship to say the least.  Having low doses of testosterone for a long time has made building up muscle much more of a challenge than [it is for] my teammates, as well as muscle recovery time. As a transgender athlete I have felt that I’ve been struggling to fight an uphill battle against stereotypes that I am physically superior to my teammates and that I’m not like them. While the physical superiority couldn’t be more false, the reality that I am very different than my teammates couldn’t be more obvious.  [But] I am myself, I don’t want to hide who I am to anyone.  Nobody should be put into a situation where they should feel ashamed or belittled for who they are."

Whilst it's very dangerous to generalise, Chloe seems to be a reasonably typical example of a undoubtedly transwoman in her teens or 20's who wants to participate in competitive sport.  And she makes a strong case as to why this should be allowed. 

The first two decades of the twentieth century may become seen as a 'golden age'  for transgender athletes.  Medical barrier after medical barrier has fallen.  Genetics tests once set an insurmountable barrier for transwomen, gender confirmation surgery still a high bar, but the testosterone level test is far more modest - and that is difficult to enforce except at an elite level,

Further, in the EU and many other countries, laws have been passed which recognize male-to-female transwomen as  being a woman - from marriage to pension rights ... to gender discrimination.  For example, in the USA the Ladies Professional Golf Association's requirement that players were “female at birth” had to be removed in 2010 after a transgender woman, Lana Lawless, successfully sued the tour in a Federal court, arguing that the rule violated California civil rights laws.

As a result of legal threats and changing social attitudes, many sporting bodies have given up trying to define who can enter their "male/men's" events and who can enter their "female/women's" events.  In order to participate in women's sports, medical requirements are now very rare and even documentary requirements such as a female passport or birth certificate uncommon. 

A Backlash

The culmination of decades of campaigning has led to almost all sports and governing bodies accepting transwomen as being women - often without SRS or GCS surgery. Essentially athletes have become free to compete as male or female by self declaration of their preferred gender.

Renee Richards' comment "How hungry for [sporting]  success must you be to have your penis chopped off" no longer applies, whilst at the same time the number of transwoman is increasing rapidly, e.g. a 2016 study from the Williams Institute, estimated that 0.6% of adults in the USA identify as transgender, whilst 1% of UK school children were officially registered as trans in 2019.

It was long assumed that the acceptance of transwomen in female sports would create the most problems at the elite or professional level, but in fact the issues have emerged at the ground roots and amateur levels where there are unintended consequences that are leading to a backlash against transwomen athletes - particularly those who have had little or no medical treatment.

One example is the Boston Marathon, arguably the most prestigious marathon in the world.  It's popularity means that the number of runners has to be capped, and this is done by means of minimum qualification times for the male and female marathons.  However the organizers no longer set any medical requirements for sex of athletes and there is a concern that the increasing number of transwomen entering the race is lowering the qualifying time and preventing cis-women from competing.  For a cis-woman who has spent several years desperately trying to qualify for the Boston Marathon, losing out to a transwoman who has had no medical treatment and easily managed the qualifying time in their only prior marathon is understandably annoying.

Most sports still follow the guidelines which were drawn up by the International Olympic Committee in 2015, which allow trans women to compete in female sport if their testosterone levels are below 10 nmol/L per litre.  However in 2017 the IAAF commissioned research which found that female athletes with high testosterone levels had a "competitive advantage" of up to 3%.   In April 2018 the IAAF introduced new rules for female runners with naturally high testosterone that effectively required them to take medication to reduce their testosterone levels to under 5 nmol/L for six months before competing as a women in events from 400m up to the mile.

A report published by the UK’s five Sports Councils in 2021 also found that key physical differences remained even after reducing testosterone to this limit, stating "there appears to be a retention of physical capacity in transgender people who suppress testosterone from male levels.  ... For many sports, the inclusion of transgender people, fairness and safety cannot co-exist in a single competitive model.”  The report also describes the extent of the competitive advantage between males and females - adult male athletes have on average a 10-12% performance advantage over female competitors in swimming and running events but this increases in jumping events and strength based events like weightlifting.  The OIC itself admitted in August 2020 that its guidelines were “not fit for purpose”.

The unsurprising result is that more transwomen are competing in women's sports at all levels with ever greater success.  Social media is increasingly filled with photo's of large and heavily built transwomen competing in various woman's sports with complaints that "it's not fair" that these are allowed to participate, and suggestions (hushed at first, but increasingly strident) that these are not "real women". For example, Rachel McKinnon claims that she received more than 100,000 hate messages on Twitter after she won the UCI Masters Track World Championship cycling title in October 2018.

Parents Launch Petition after Transgender Athletes Place First and Second in Girls Track Championships

June 18, 2018


Andraya Yearwood

Two athletes who were born males placed first and second in state track championship events for high school girls, causing anger among other competitors and parents who say they had an unfair advantage over the girls.

Terry Miller and Andraya Yearwood dominated Connecticut’s races, sweeping gold and silver medals with little competition and stirring outrage among fellow competitors. Miller placed first in both the 100-meter and 200-meter dash, while Yearwood placed second to Miller in the 100-meter dash, CBS Pittsburgh reported.

Both Miller and Yearwood are biological males who identify as females. Neither has undergone surgeries or used hormone blockers to lower their testosterone to a level comparable to females.

The Connecticut Interscholastic Athletic Conference allows athletes to compete according to their gender identity and implements no hormone testing, as regulatory bodies do at the university level.
 

Parents began a petition after transgirl Andraya Yearwood took first place in the women’s 100 meter dash for a second consecutive year, it soon gained hundreds of signatures.  “I think it’s unfair to the girls who work really hard to do well,” said another sprinter, Selina Soule. She explained that she doesn’t think it’s fair for boys who identify as girls to race together when boys are faster and stronger than girls.

In October 2019,  Cheryl Radachowsky, a mother of a high-school female athlete wrote an impassioned piece in the New York Post about how her daughter was among those being affected by a 2017 Connecticut state ruling that boys who subjectively identify as female could compete against girls.

“Since then, two biological boys have won 15 women’s track championships, titles held by nine different girls in 2016.  As a parent, it is gut-wrenching to know that no matter how hard my daughter works to achieve her goals, she will lose athletic opportunities to a pernicious gender ideology. A biological boy’s subjective sense of his gender doesn’t cancel out his physical advantage over girls.

 

A Crisis Point

The IOC's decision in 2004 to allow post-SRS transwomen compete in women's sports seemed extraordinary at the time.  Whilst it caused some mutterings of discontent from elite female athletes, the number of (known) transgender athletes was so low that this seemed a reasonable compromise.  It seemed to have so little impact on women's sports that the "politically correct" follow on decision in 2014 to lower the eligibility criteria for transwomen to just a testosterone level test was much easier to make. 

Lauren Hubbard "crushed" her opponents in women's weightlifting competitions in 2017-18.  Before transitioning, she had set several records in male categories as Gavin.


Lauren competed for New Zealand in the Tokyo 2020 Olympics (held in 2021).  She was the first openly transgender woman to do so.

Unfortunately the IOC failed to recognised the explosion in the number of young people with gender identify disorders.  In recent years there has been a huge increase in the number of MTF transwomen who want to participate in female sports, and most sporting organizations now allow transwomen to compete in women's sports, indeed they would potentially face legal challenges in many countries if they didn't.  It takes only a small amount of research show that transwomen are now participating in women-only sports such as synchronized swimming, rhythmic gymnastics, softball, netball and lacrosse. 

Multiple studies have now found that MTF transwomen, regardless of hormones levels, tend to be bigger, stronger and faster than their cis-counterparts. We seem to be moving to the situation where transwomen will dominate some women's sports, the leading contenders being: weightlifting, track, wrestling, football, basketball, and mixed martial arts.  When a transgender weightlifter won (yet again) a competition, Deborah Acason, from the Australian Weightlifting Federation, said "We all deserve to be on an even playing field, it’s difficult when you believe that you’re not.  If it’s not even, why are we doing the sport?”

Will Thomas competed for two years in the University of Pennsylvania's men's swimming team until November 2019 with modest success.  In 2020, age 20, he decided to take took a season off whilst transitioning Lia.  Her subsequent re-emergence in 2021 as a member of UPenns female swimmer was spectacular.  She won a 1,650 yards freestyle women's event by 38 seconds (a full length!) and a 500 yards freestyle women's event by 14 seconds.  Lia set two USA female swimming records and was regularly close to world records for female swimmers.  She was about 5% faster than her closest female cis-competitor in the National Collegiate Athletic Association (NCAA) championships - an extraordinary difference!


Linnea Saltz (left) and June Eastwood

An opposite story faced Southern Utah University sprinter Linnea Saltz in early 2020.  Age 19, she was preparing to defend her 800 metres 'Big Sky' title when she learned that a male athlete - Jonathan Eastwood - at the University of Montana had transitioned and would now be running for their women’s team as June.  The Montana athlete had a personal best a huge 10 seconds lower than Linnea's 2 minutes 5 seconds, Saltz said she then realized that her season wasn’t going to be about her hard work, pain and sacrifice to be a champion, but about fairness in women’s sports being "stripped away right in front of me".

Some parents are understandably getting upset when they see their cis-daughter trying to compete physically with much bigger, heavier and stronger transgirls.  The parents of the girls who competed against Lia Thomas' sent a letter of demand to America's National Collegiate Athletic Association (NCAA), urging the sporting body to alter its rules -  "At stake here is the integrity of women's sports," the parents wrote in the letter.  Another problem was Lia was pre-SRS and still had a male anatomy, whilst her team mates were urged by the University to be supportive of Lia, they were reported as being uncomfortable about sharing the women's changing with her. 

When facing her critics, Lia claims to have lost a lot of muscle mass since since starting puberty blockers and hormones.  She points out that she was much faster in 2019 when still competing as a male, e.g. 14:54:76 vs 15:59:71 in the 1,650 yards freestyle, and 4:18:72 vs 4:34:06 in the 500 yards freestyle.  Similarly, the times June Eastwood ran on the University of Montana’s women’s cross country and track teams after a year of hormone therapy were lower than her times on the men’s team, whilst she was repeatedly close to breaking women's records he was not dominating competitions in the way that Lia was.  June decided not to run the 800m Big Sky race - which Linnea won - but she did enter and easily won the one-mile race. The parent's of some transgirls also counter argue that their children are actually at a physical disadvantage in sports such as woman's artistic gymnastics, rhythmic gymnastics and figure skating - where a small and lightly built physique is very advantageous.

In March 2022 Lia become the first transgender person to win a womens NCAA Division I title, beating a USA medallist at the Tokyo Olympic Games in the 500-yard freestyle.  Her victory received a mixed reaction from spectators and other competitors
.

Lia's staggering success has led to the USA Swimming governing body having to act.  In early 2022 it issued a new policy which acknowledges that transgender participants may have "a competitive difference in the male and female categories and the disadvantages this presents in elite head-to-head competition".  Participants in women’s events now have to record low levels of testosterone for 36 months prior to competing, and they will be assessed to determine whether "prior physical development of the athlete as a male" gives them an unfair advantage.  For example Lia's hands are estimated to have double the surface area of the average cis-female swimmer.

Realistically, the new USA Swimming policy is attempting to 'square the circle'.  Elements of its new policy are both subjective and subject to legal challenge.

What Next?

Despite an increasingly vocal lobby to prevent the participation of transwomen in female sporting events, implementing this would now face a legal challenge in most countries and would almost certainly be ruled against. 

The situation is likely to get even more complex as an increasing number of states and countries pass laws that allow people to self-declare their gender and sex.  For example, Scotland plans to pass an Act (the Gender Recognition Reform (Scotland)) in 2022 that will allow men to legally self declare themselves as a woman, without requiring any medical treatment and regardless of regardless of any prior documentation such as birth certificate or passport.  As such, men could legally compete as a woman in female sports if they so wished. 

A study by the UK Sports Council's concluded that "For many sports, the inclusion of transgender people, fairness and safety cannot co-exist in a single competitive model”.  This is a pragmatic acceptance that there is a serious problem.  However the hint that there should be a separate sports category for transwomen will be difficult to realise.

Renee, Kia and some sports organizations such as USA Swimming and the Women's Sports Federation seem to believe (albeit from an interpretation of their different approaches) that transsexuals should be evaluated on a case-by-case basis before being allowed to compete as women.  But there is then an implication that transwomen will have to be below a certain age, height, weight or strength before they are allowed to compete as women in a certain sport - and "discrimination" is a word that will inevitably be raised in court by someone that fail the tests.

I'm not sure what the answer is.  I agree that allowing adult men with no medical treatment to self-certify themselves as female and then be able to compete in women's sports against cis-woman is unfair to the later, whilst at an elite level it is starting to distort results and records.  A few unstatisfactory alternative options are:

  1. Introduce sporting events or categories specifically for transgender individuals.  But this approach will almost certainly be quickly challenged and judged illegal in countries where a transwomen is legally female.
  2. Impose rigorous conditions such as requiring that a transwoman is post-GRS, has cis-female levels of testosterones, and her physique is within three standard deviations (99.7%) of the global cis-female average.  This approach will again almost certainly be quickly challenged and judged illegal in some countries.
  3. Try to find legally acceptable ways of limiting some competitions and events to primarily cis-women. 

The last option seems to be the best route for Women's sport federations whose competions are becoming distorted by the participation of transwomen.  For example, it can be argued that requiring a competitor to have "XX" genes in order to enter a particular sporting event is a clear definition that is no more discriminatory than requiring competitors in an over-45's road race to prove that they are over the age of 45.  But this sadly takes us right back to the situation that transwomen faced in the 1960's, whilst being a disaster for intersex women such as those with AIS that have long been accepted as women for sport events.
