Our Position

See also these comments for detailed reactions to the Biden Administration’s Proposed Title IX Regulations, March 15, 2023.


It’s always been unfair for men to compete against women, and it’s still unfair.

Executive Summary

We are women’s sports advocates: champion athletes, coaches, and sport administrators who have dedicated much of our careers to addressing sexism in sport. Since 2019, we have met at least weekly to affirm and strengthen girls’ and women’s legal right to separate, single-sex sports competitions.

For more than fifty years, since the passage of Title IX in 1972, the federal government has recognized the need for formal sex segregation in sport: a practice firmly grounded in physical reality, science and biology.

The purpose of sport categories is to exclude. The purpose of the women’s sports category is to exclude men. We resist calls for a reversal of this common sense policy, which would allow inclusion of male athletes into the female sport category. Gender ideology[i] – akin to a religion – holds that people’s belief that they are male or female or neither (“nonbinary”) or both (“gender fluid”) should take precedence over biological facts. Adherents believe a transgender status should grant those people access to girls and women’s sports and other sex-segregated spaces.

Competitive sport must be formally sex- separated[ii] because of immutable physiological sex differences that impact performance.

We encourage equitable and inclusive accommodations for males who identify as women; gender-fluid athletes; and nonbinary athletes, so long as those accommodations do not diminish females’ sport opportunities or financial rewards, nor females’ right to fair, safe, sex-separated sports experiences.

We use this language to communicate effectively:

  • We use the word sex to refer to natal or biological sex, which is immutable.
  • Gender refers to a psychological state or identity and includes “transwomen,” “transmen,” “gender-fluid,” “nonbinary,” and any other gender identity that people may adopt.
  • We use the words female, male, girl, boy, woman, and man to denote a person’s biological sex, regardless of their gender identity.[iii]
  • We use the word transgender as a term for people of either sex who call themselves trans or transgender.
  • We use the phrase “males who identify as transgender”[iv] to specify the gender identity and sex of males who wish to present themselves as women and enjoy women’s rights, including participation in the female competitive sports category.
  • We do not use the words cis or cisgender, terms that were invented by the trans community, to refer to females who have always been female because males cannot become female.

We mean no disrespect to transgender people who prefer different terms. Our goal is to be clear: Sex is immutable. Sex is not fluid. Males cannot transform into females. Women are adult human females. These definitions have meaning and consequences in women’s sports, especially as they pertain to eligibility rules that allow or disallow certain people into women’s sports.

Female Sports Are for Female Athletes.

“Trans women are women” is a political slogan and should not be implemented into sport law, policy, or practice.

We ask the Administration to confirm Title IX’s and the Amateur Sport Act’s [v]intention to provide females with equitable[vi] and safe opportunities in competitive sport.[vii] Under both of these statutes, official, government-sanctioned sex segregation has been formally allowed – including in the Department of Education’s regulations, in case law, and in numerous Congressional testimonies – and for decades. This continued affirmation can be accomplished by revising the Department of Education’s proposed regulations or by adopting a stand- alone federal statute. Either way, we ask the federal government to clarify that competitive sport must continue to be formally sex-separated8 [viii] because of immutable sex differences that impact performance.

1. We Support the Transgender Community and Their Desire to Identify Differently from their Biological Sex, But in Sport, Sex Matters.

We support transgender athletes’ rights to identify as they see fit. We support their right to be treated as women or men or “nonbinary” or “gender fluid” without regard to sex in other spheres of human endeavor, where biology is not the relevant consideration, such as most employment, classrooms, housing, family law, etc. We are in agreement with the Supreme Court’s Bostock v. Clayton County decision,9 [ix]regarding Title VII workplace discrimination. Bostock held that Title VII’s prohibition on “sex discrimination” equated with “SOGI” – or sexual orientation and gender identity gay, lesbian, gender-non-conforming, and transgender people – except in rare cases like personal care. For sport competition, gays and lesbians are not implicated in our discussion of limits on non-discrimination based on gender identity.

However, as that case notes, competitive sport is one of the few places where biological sex differences matter. Men have greater strength, size, speed, and muscle mass. Men have larger hearts, lungs, hands, feet, and skulls. Women have greater body fat, and it is distributed differently than men’s body fat. [x]  These enormous sex differences result in performance advantages for men in almost every sport. [xi]

In sports, sex matters. Indeed, sex is the most powerful performance determinant of all, which is why formal sex segregation is ubiquitous throughout all of sport. When categories are established based on such things as age, disability, or weight, participants are always further divided into male/female sex categories.

Male performance advantages comprise the original and ongoing rationale for separate competitive-sport categories for women and men and Title IX’s prohibition of discrimination based on sex. Female sport segregation is not based on a remedy for past discrimination. Nor is it based on sparing men’s feelings by the threat of being beaten by a woman. Rather, sex segregation is practiced internationally, and is based on scientific facts. As longtime women’s sports advocates, we’ve been repeating ourselves for over 40 years: to give girls and women equal opportunities in sports, they need their own teams. If the law had instead developed to permit schools to offer one team – say, a basketball team – per sport, females would be almost entirely absent from this type of educational experience. We continue to advocate for girls’ and women’s right to our own sports.

2. Schools Are Already Impermissibly Truncating Girls’ and Women’s Sports Opportunities, Scholarships, Treatment … DESPITE Excellent Statute, Regulations and Case Law.

The promise of Title IX has not been realized, more than 50 years after its inception. High school girls are provided with one million fewer sports opportunities than boys. College women are denied 60,000 opportunities as compared with men.[xii]  Every year, women lose out on over one billion dollars in college athletic scholarship dollars.[xiii]

  • These numbers do not include the second class, less-favorable treatment of women when it comes to facilities, coaching salaries, travel, healthcare, trainers, equipment, recruiting, publicity, promotion, and other benefits of athletic programs.[xiv]
    • New Name, Image, Likeness monies are already being distributed unequally, and given the lack of oversight, the financial disparity between women and men is likely to get worse.

Against this backdrop of ongoing sex discrimination against girls and women in high schools and colleges sports, we cannot now allow more sex discrimination: male athletes who identify as transgender taking participation slots or scholarship dollars that rightfully should go to females.

3. Title IX’s interpretation on transgender accommodations must happen at the federal level.

The issue cannot be resolved by individual states, sport governing bodies, or schools. Interstate commerce would inevitably be disrupted. Sponsors, media, travel, and fans would all be disrupted. Such a hodge-podge of rules and regulations would be a logistical, financial, and legal nightmare for any student or school. Neighboring schools would undoubtedly devise different rules: some will assure the women’s category is reserved for females, while their competitors may adopt rules allowing any male who identifies as transgender to compete on opposing women’s teams. The physical safety risks to athletes, the school’s liability safety risks, as well as the competitive unfairness of being required to compete against schools with differing rules, would be untenable. Instead, all eligibility rules must be easily understood and enforced nationally. That enforcement consistency can only be achieved with objectivity and plain language across-the-board.

  • When it comes to sports participation, the definition of sex in Title IX and the Sports Act should be interpreted as an immutable biological characteristic, as it was in the 1975 Title IX regulations.[xv]
    • For reasons of fairness and safety, all competitive sports opportunities for girls and women must be reserved for females.
    • At a minimum, “all competitive sports” should encompass all junior varsity and varsity sports.

4.  Allowing Male Athletes Who Identify as Transgender into the Girls’ and Women’s Category is Sexist.

First, girls’ and women’s sports are not the “B” team, a place for the male who identifies as transgender but is not qualified for the men’s team to dominate the women’s competitions. Second, the inclusion of males into women’s sports sends the message that females are not deserving of their own sport category, that their teams, their wins, their accomplishments are not as inviolable as we had presumed. Third, female physiology is not akin to weakened males. We need to be respected and celebrated for our own unique, perfect physiology. There is nothing wrong with women’s physiology. Finally, “trans inclusion” only disadvantages girls and women; it never disadvantages boys or men, because girls who want to play on boys’ teams never pose a competitive threat. [xvi] This means men’s sports are left to operate unchanged, while women are being threatened with the loss of their hard-won opportunities, their scholarships, their wins, their records, their prize money, their status as role models – all taken away.

5.  Males Who Identify as Transgender Should Welcomed and Accommodated.

All students should be able to participate in sports, and males who identify as transgender are no exception. Accommodations can include competing in the men’s category or an “open” category for everyone who is not female. Alternatively, schools and sport governing bodies could create new categories for transgender athletes who wish to compete based on their gender identity, so long as there is no direct competition with females and no overall reduction of female athletes’ right to their share of all participation opportunities and scholarships, as guaranteed by long-standing Title IX regulations. [xvii] But as a rule, males must not be allowed to breach the immutable-sex boundary that legally constitutes formal, government sanctioned separate-sex sport.

6.  The Term “Sex” Must Be Based on Biology and Science Because Sex is Immutable, While Gender Identity is Not.

Sex is an immutable characteristic, protected under the U.S. Constitution. Allowing males, however they identify, to compete against women in women’s sports is sex discrimination. Legally, Title IX requires schools to apportion participation opportunities and financial aid equitably between males and females. The justification for separate-sex sport is based on humans’ biological, immutable differences; males and females cannot fairly compete against each other. It follows that the apportionment of financial aid, scholarships, prize money, and opportunities to compete must be based on immutable physical characteristics.

By its very definition, gender identity is not immutable.[xviii] A person’s identity can change; it is fluid. Indeed, some people’s gender identity is to be “gender fluid”; they declare themselves to be women one day and men the next.[xix] So biological sex – the unchangeable, immutable quality of being female or male – must be the criteria used to fairly allocate resources and opportunities in sport, rather than gender identity.[xx]

The desires of males who identify as transgender to play women’s basketball or women’s volleyball or women’s tennis or women’s swimming must not take precedence over female athletes’ longstanding, Title-IX-enshrined rights to play on teams of their own.

Girls and women are not biologically compatible competing against their male counterparts, and high schools and colleges are already providing males with about a quarter more opportunities to play high school and college sports.

7. Specific Policy Recommendations to Protect the Female Category

  1. A clear, unambiguous, unified federal policy that preserves girls’ and women’s competitive sport category is necessary. It must assert that all competitive sports, including varsity and junior varsity sports, must continue to be formally sex segregated.
  2. Girls should not have to demand their rights to benefit from the promise of Title IX while their brothers take for granted their sports participation opportunities. Clear federal rules must protect females’ rights.
  3. The definition of sex, as it applies to sports, should be interpreted as an immutable, biological characteristic, consistent with the long-standing 1972 Title IX statute and the 1975 Title IX regulations.
  4. The determination of sex, for purposes of participation in interscholastic, intercollegiate, Olympic, or non-school sport, should be based on the existing annual medical clearance process for athletic participation.[xxi] Standard forms from an athlete’s physician that denote a person’s sex have been completed for decades, with confidentiality already protected by federal law. Sex verification should never involve physical or genital examinations or verbal challenges by school personnel.
  5. For grades 6 through college, athletic participation should be based on sex, not gender identity, regardless of hormonal treatments or surgeries.
    • Transgender athletes should be welcomed and encouraged to participate in interscholastic and intercollegiate sports based on their sex.
    • Schools and sport governing bodies can create accommodations for male or female athletes who identify as transgender and have used testosterone so long as there is no direct competition with females and no overall reduction of female athletes’ right to their percentage share, as currently defined in Title IX regulations, of all participation, scholarship, and prize-money opportunities in college and beyond.
    • Men’s and women’s coaches and teams should be educated about how to provide a welcoming environment for gender-nonconforming athletes (such as females who refuse to wear makeup and males who do wear makeup, regardless of gender identity).
  6. In all cases, females have a right to safety, privacy, and dignity in single-sex changing spaces, showering and toilet facilities.[xxiii]
  7. Transgender athletes should be provided with separate changing, showering, and toilet facilities if they feel uncomfortable in spaces designated for their sex.
  8. Female athletes must not be allowed to take performance-enhancing drugs while competing in the female categories.
  9. Males who identify as transgender should not be eligible to compete in the female category, regardless of performance-mitigating drugs or surgically altering any body part.[xxiv]

8. Science Supports the Women’s Sports Policy Working Group andChampion Women’s Policy Recommendations   

A. Pre-Puberty, Male and Female Children Show Marked Differences in Sport Performance.

Scientific evidence supports our central idea: competitive sports should remain sex segregated. Even pre-puberty, males have substantial testosterone-based advantages, which begin before birth. In utero, male fetuses receive an infusion of testosterone that is later associated with young boys’ somewhat greater strength [xxv] and somewhat greater propensity for aggression – the androgenic effects of testosterone. [xxvi]  For example, fitness data from over 85,000 children in Australia showed that, compared to nine-year-old females, nine-year-old males were 9.8 percent faster in sprints (running) and 16.6 percent faster in the mile run. They could jump 9.5 percent farther, could complete 33.3 percent more pushups in 30 seconds, and had a 13.8 percent stronger grip. [xxvii]

Significant male advantage was also found in a study of Greek children pre-puberty. Compared with six-year-old females, six-year-old males completed 16.6 percent more shuttle runs in a given time and could jump almost ten percent farther from a standing position. [xxviii] Another Danish study showed six- and seven-year-old males had a higher aerobic capacity (VO2max) than girls in the same age group. [xxix]

A 2022 analysis of American swimming records showed that boys’ records in the ten- and-unders (nine and ten-year-olds) average 0.57 seconds faster per 100 yards than girls’ records. Boys’ records jump to an average of 3.01 seconds faster per 100 yards for the 12-and-under group and more than 4.5 seconds faster per 100 yards between the ages of 13 and 18. Jerry Giordano, an attorney who conducted the analysis, concluded that “about two-thirds of the eventual male-female differential in the performance of top swimmers emerges by the age of 12.” [xxx]

The pattern is even more dramatic in children competing in track. Every USA Track & Field age-group national championship record is better than the girls’ record. This is true beginning with the youngest competitive age group (eight-and-under), with the gap growing dramatically during and after puberty.

According to Greg Brown, professor of Exercise Science at the University of Nebraska at Kearney, “Before puberty, boys tend to outperform girls of the same age in tests measuring muscular strength, muscular endurance, running speed, aerobic fitness, ball throwing, and kicking distance. Conversely, girls typically exhibit better performance in tests focused on flexibility. While physical fitness tests do not always accurately predict success in competitive sports, physical fitness is often a prerequisite for success in sports.”

B.  Post-Puberty, The Gap Between Male and Female Sport Performance Explodes. Medication and Surgery Do Not Remove the Male Sport Advantages, Even After Many Years.

Male performance advantages are dramatically accentuated beginning with the onset of male puberty. [xxxi]  As a group, male bodies become faster, stronger, and more powerful than female bodies. The performance gap between male and female athletes that accelerates at puberty ranges from 8-20 percent, but up to 50 percent depending on the sport and event. [xxxii]  The performance advantages cannot be erased via testosterone suppression.[xxxiii] [xxxiv]

This chart shows the gap is between the two sexes, and how precarious the situation is for women if males who identify as transgender are allowed to compete against them. [xxxv]

  • The far-left column shows the track events.
    • On the far-right column are women’s world records.
    • The middle column shows the age of high school boys when they beat the women’s world records.
  • Note that for the discus, shot put, and javelin, women throw objects that are significantly lighter; teenage boys, throwing heavier objects, still “win.”

To ensure that female athletes have access to fair and safe competition, males who identify as transgender at any age must not be eligible to compete against females.

9.   Sport Achieves Diversity, Equity and Inclusion by Creating Categories Based on Objective Measurements and Standards.

Sport categories facilitate inclusion of different types of bodies; it is how sport creates diversity, equity, and inclusion. Sport categories include weight classes in boxing, wrestling, rowing, and judo; age categories for children and older athletes; and Paralympic categories for people with disabilities. All categories allow more athletes to compete and allow different athletes to experience the benefits of sport. For example, weight categories allow smaller athletes to shine, age categories allow younger or older athletes to reap the benefits of sport. Without sport categories, young men would win all competitions.

To illustrate the importance of sport categories, consider the Paralympic Games. Each athlete is evaluated to determine the extent of their disability, which determines which category the athlete will compete in, which in term determine the likely winners and losers. Category manipulation is common, as some Paralympic athletes try to get an edge by becoming eligible in a more disabled category. [xxxvi] These Paralympic athletes can win with a category that is meant for more disabled athletes, similar to males who identify as transgender winning in a category meant for females.

Sports participants do not get to choose their sport category. Athletes are eligible for the sport category or they are not. Because of the enormous male performance advantage, males, however they identify, are ineligible to compete in the females sport categories.

Separate, sex-segregated sport categories provide more people with a chance to enjoy competitive victories. Without the two sex categories, female and male, we would never have known about or celebrated the greatest female athletes of all time, including but by no means limited to these household names: Martina Navratilova, Mia Hamm, Jackie Joyner-Kersee, Lindsey Vonn, Serena Williams, Simone Biles, Allyson Felix, Wilma Rudolph, Mary Lou Retton, Nancy Lopez, Joan Benoit, Peggy Fleming, Lisa Leslie, Ann Meyers, Donna de Varona, Nancy Hogshead, and Billie Jean King. All would have been defeated by and overshadowed by countless male competitors and lost to history.

10.  Sport Governing Bodies, Nationally and Internationally, Are Quickly Affirming Sex Segregation in Sport

In 2022, World Aquatics, the international governing body for swimming, diving, and other water sports, formerly known as FINA, undertook a thorough review of the research and concluded by acknowledging the immutable physical differences between women and men. This led to a rules change that excludes from women’s events people who have experienced male puberty. [xxxvii]  In 2023, World Athletics, the international governing body for track and field and all running events, followed suit with similar rules that designate the female categories as just for women. The International Rugby League, the World Boxing Council, USA Powerlifting, USA Swimming, and Volleyball England provide examples of other national and international organizations that have recently issued similar rules for women. The International Body for Cycling, UCI, is undertaking a review after a male who identifies as transgender won an elite race created specifically to give women more opportunities in cycling – a win that gave the winner’s share of a $35,000 prize to a male. [xxxviii] 

11.  Policies That Affirm a Female Sport Division Are Often Mis-Framed As “Anti-Transgender” or as “Exclusionary.” They Are Not. Transgender Athletes Must Be Accommodated in Their Proper Sport Category, Based on Biology, Like Every Other Athlete.

Males who identify as transgender should be accommodated so that they, too, can comfortably participate in sports. For trans-identified males who are uncomfortable playing with and against boys or men, such accommodations could take the form of separate scoring for individual sports, separate leagues for team sports, new transgender categories, or other solutions – so long as there is no direct competition with females and no overall reduction of female athletes’ right to their rightful percentage of all participation, scholarship, and prize-money opportunities.

12.  Females Who Identify as Transgender Must Also Be Accommodated in Sport, Especially After Starting Performance-Enhancing Drugs Like Testosterone.

Females who identify as transgender often play on women’s teams, until they start taking testosterone or other prohibited drugs. At this point, these females could play on men’s teams, but females on testosterone or other performance-enhancing drugs will rarely – if ever – be competitive in the men’s sport category. [xxxix] Schools and sport leaders should consider providing these females who identify as transgender with accommodations similar to those discussed for trans-identified males.

Note that male athletes face no parallel crisis due to an influx of females who identify as transgender into the ranks of men’s sports. The fact is another reminder that biology matters.

It is worth repeating: females taking testosterone must not be permitted to play against women. [xl]  In addition, responsible measures should be undertaken to ensure the safety of these females on men’s teams.

13.  Girls and Women Are Entitled to Privacy and Dignity in Changing, Toileting, and Sleeping Spaces.

In all cases, female and male athletes have a right to privacy and must be provided with safe, private places to change clothes and shower. Neither male nor female athletes should be asked or required to share hotel rooms or other overnight accommodations (such as bedrooms in private homes) with members of the other sex, regardless of how those people identify.

14.  Girls and Women Are Entitled to Be Safe in Changing, Toileting and Sleeping Spaces, Away from Males.

Females have not abandoned their legal right to privacy from males. Separating women and men in locker rooms is a nearly universal phenomenon, a custom that female athletes have come to expect and rely upon. Women are vulnerable when undressing. Criminal laws have protected women from male voyeurism for hundreds of years.

Because women know that men are far more likely than women to commit sexual assault, the presence of males can be inherently threatening, even traumatic, to women as they are undressing or showering.[xli]  Naked men also make women vulnerable; exposing male genitalia is typically a criminal act of indecent exposure or flashing. [xlii]  

In particular, the presence of naked or near-naked men can feel threatening and traumatic to women who have already been harassed or sexually assaulted. Twenty-six percent of college-age women report having been sexually assaulted while attending college. [xliii]

Fears of locker-room assaults are not unfounded. According to one recent investigation of complaints of sexual assaults, voyeurism, and harassment at public fitness centers and swimming pools in London, almost 90 percent of sexual offenses against females took place in unisex changing rooms.[xliv]

Several world religions prohibit women from being in the same room with males. Enabling males who identify as transgender into these spaces puts an enormous burden on these women.

Excluding males who identify as transgender from women’s locker rooms does not imply that these transgender athletes are inherently violent. But in fact, a longitudinal, quantitative study by Swedish researchers found that post-operative males who identify as transgender[xlv]  had criminal-conviction rates that were comparable to male controls. In other words, sex reassignment did not decrease men’s risk for criminal convictions.[xlvi]  Males who identify as transgender are not dangerous to females because of their gender identity; they are dangerous because they are male.

Sex-segregated changing spaces provide girls and women with protection from:

  • undressing and showering in front of males;
    • revealing such intimate details as when they are menstruating;
    • displaying vulnerable rituals such as when swimmers help each other squeeze into tight, competitive swimsuits;
    • seeing naked male bodies; and
    • hearing male commentary about their naked bodies.

15.  Girls’ and Women’s Rights Should Be Respected by Adults, Not Just in School Competitive Sport, and Not Just by Their Peers.

These conditions and accommodations should apply to age-group club competitions; competitive interscholastic, intercollegiate, and developmental elite athletic programs; and the U.S. Olympic and Paralympic movement. They should be used as guidelines for any competitive youth and age-group and AAU sports, such as swimming and track, that involve rules; scorekeeping; adult organizers, referees, or umpires; and, ultimately, one or more winners.

When sports involve adults such as coaches, organizers, referees, or umpires, those adults should follow the same privacy and safety single-sex rules.

Formal sex-segregation is unnecessary in physical education, intramurals, or recreational sports sponsored by municipalities, schools, and colleges. Sex- segregation rules should not interfere with children’s or adults’ decisions to organize non-competitive, coed sports with any number of female and male participants when the only goal is to have fun. [xlvii]

16.  Performance-Enhancing or Performance-Mitigating Drugs Should Be Impermissible for Sport Eligibility. Ingesting Drugs Is Contrary to the World Anti-Doping Agency (WADA) and the United States Anti-Doping Agency (USADA) Policy and to Accepted Principles of Fair Competition.

No eligibility rules should force an athlete to take drugs to meet a standard consistent with their gender identity. However, some people who identify as transgender take drugs such as testosterone, estrogen, and testosterone-suppressing medications, in order to address their gender dysphoria. Doping governing bodies will need to determine when transgender athletes could qualify for therapeutic-use exemptions (TUEs). New transgender athlete categories could choose to allow TUE exemptions.

Women’s Sports Policy Working Group and Champion Women

The Women’s Sports Policy Working Group is a bipartisan think tank comprised of champion athletes, coaches, and sports administrators dedicated to affirming and strengthening girls’ and women’s legal right to separate, single-sex sports competitions. We encourage any equitable and inclusive accommodations for males who identify as women; gender-fluid athletes; and nonbinary athletes so long as those accommodations do not diminish females’ opportunities, financial rewards, nor their right to fair, safe, separate sports experiences.

[i] For a more thorough understanding of the philosophy of gender ideology, we recommend Helen Joyce, “Trans: When Ideology Meets Reality,” September, 2021; Linda Blade, “Unsporting: How Trans Activism and Science Denial are Destroying Sport,” May 2021, and Kara Dansky’s “The Abolition of Sex: How the “Transgender” Agenda Harms Women and Girls,” November 2021.

[ii] The terms sex-segregated and sex-separated both refer to separation according to sex, regardless of athletes’ gender identity.

[iii] “Girls” and “women” are not weakened males. If a male removes his legs and is now much slower than he was pre-amputation, he is not eligible to compete in female categories. The same principle is true for males taking drugs or have surgery that may weaken them.

[iv] Transgender does not mean what transsexual used to mean. According to recent research by the Washington Post and the Kaiser Family Foundation, 62 percent of trans adults identify as “trans, gender non-conforming” or “trans, nonbinary,” while only 33 percent identify as a “trans man” or “trans woman.” Just 31 percent have used hormone treatments, HRT, or puberty-blocking hormones, and only 16 percent have undergone “gender-affirming” surgery or another surgical treatment to change their physical appearance. This survey was conducted on adults; one can reasonably assume that schoolchildren and college students are even less likely to have used medication or undergone surgery. Therefore, the vast majority of trans-identified males (at least 84 percent) who seek to compete against female athletes have not had surgery, and at least 69 percent have not taken any medications.

[v] 36 U.S. Code § 220501, the Ted Stevens Olympic and Amateur Sports Act.

[vi] We use the word equitable rather than equal because schools are not required to provide males and females with mirror image sports; schools are not required to offer football to females or require male gymnasts to perform on the balance beam; schools remain free to pick very different sports to offer males and females; individual, team, or contact sports, so long as males and females are provided with equality overall. But make no mistake, “equity” does not mean “less-than” – the law requires that schools provide both sexes with non-discrimination on account of their sex.

[vii] The term competitive sport refers to interscholastic, intercollegiate, age-group club competition, and elite contests, such as the U.S. Olympic and Paralympic movement and its developmental programs.

[viii] The terms sex-segregated and sex-separated refer to separation by sex, regardless of gender identity.

This research is one of the most cited ever in academic literature. It definitively establishes that no amount of testosterone reduction can make male competition in women’s categories fair or equal, even when the athlete has been on testosterone blockers for many years.

[xix] Trans advocates regularly dismiss the idea that people would claim to be transgender when they are not. But as experts in sport, we can assure readers that people cheat in sport. It is expected and millions of dollars are spent ensuring opponents do not have the slightest unfair advantage.

[xxxix] East German women were given large amounts of performance enhancing drugs like testosterone; enough so that they developed male secondary sex characteristics. Many suffered through lifelong medical problems, including infertility and birth defects. East German women swam slightly faster than their female peers, but they were never competitive against the male athletes of their time.

[xl] Taking steroids and other performance enhancing drugs are effective, meaning they do indeed give athletes taking those drugs unfair competitive advantages. Gender identity should not be a permissible reason to compete against women while under the influence of these drugs.

[xli] Statistics on male violence against women remain stubbornly high. According to the FBI, Males are responsible for 97% of murder and non-negligent manslaughter, 96.8% of rapes, 96% of pedophilia cases. See “FBI Crime in the United States 2018.” According to RAINN, 9 out of every 10 victims of rape are female.

[xlii] Most trans-identified males do not undergo surgery to remove their penis and testicles. According to three recent studies, only between four and sixteen percent of transgender people undergo genital surgery.

[xlv] The study used the term male-to-female transsexuals rather than more modern terms: transwomen or trans-identified males.

[xlvi] The study also compared conviction rates of post-op trans-identified males to those of women to test whether trans-identified males successfully became similar to women in that way. They did not. Their rates of conviction, like men’s overall rates of conviction, remained significantly higher than women’s.

[xlvii] As described above, coed competitions are permissible with a balanced number of females and males on each team, such as mixed doubles in tennis or mixed running or racing relays, so long as all participants compete based on their birth sex.
