An IOC-commissioned study comparing transgender and cisgender athletes found:
This peer-reviewed study examined how feminizing hormone therapy affects athletic performance:
A comprehensive systematic review of transgender athlete research found:
Kirsti Miller is an Australian Olympian, trans athlete, and researcher who co-authored peer-reviewed studies on transgender athletes. She has dedicated her work to debunking myths about trans athletes in sports.
On Olympic Participation Reality:
"Since the IOC has created a rule for trans athletes to compete in 2003, over 71,000 people have become Olympians. Out of those 71,000 Olympians a total of 2 have been trans women & one came dead last the other came 37th out of 42."
— Kirsti Miller
On Trans Athletes Being Under-Represented:
"Many politicians & the TERFS circulate myths about trans women that are transphobic, harmful, & violent. For example, that trans women will overwhelm women's sport, when trans women are in fact under-represented in sport and especially elite sport."
— Kirsti Miller
On The "Divide and Conquer" Tactic:
"Many who oppose the inclusion of trans athletes erroneously claim that allowing trans athletes to compete will harm cisgender women. This divide and conquer tactic gets it exactly wrong."
— Kirsti Miller
On Female Athlete Support:
"A study has confirmed what we all already knew – that the majority of female athletes have absolutely no problem with trans women competing in women's sports."
— Kirsti Miller
On Individual Assessment vs. Blanket Bans:
"Assessing any group of athletes as a monolithic group especially amongst trans athletes is flawed. The sex, gender or chromosomal status of an athlete does not create any inherent danger or risk to safety. Rather, it is disparities in strength, speed & endurance and/or physique of each individual athlete that may, depending on the sport."

Official resource summarizing research findings on transgender athletes.
This site exists to counter misinformation spread by SheWon.org and HeCheated.org, which use dubiously-sourced claims and inflated statistics to suggest trans women have competitive advantages—despite peer-reviewed evidence showing the opposite.
These sites:
When you search for information about trans athletes in sports, you deserve accurate, evidence-based answers grounded in peer-reviewed research—not anonymous misinformation. This site provides them.
SheWon claims hundreds or thousands of female athletes have been "displaced" or had "medals stolen" by trans women.
The Problem: This methodology is fundamentally dishonest. A trans woman winning a medal doesn't automatically mean a specific cisgender woman "lost" it. These sites count any medal won by a trans athlete as a "displacement," artificially inflating numbers without scientific or logical basis. Even the Supreme Court noted this "calculation algorithm artificially inflates the number of medals 'lost.'"
SheWon and HeCheated operate with anonymity while being documented to have connections to extremist communities and organizations designated as hate groups by the Southern Poverty Law Center.
The Problem: Credible research is transparent about who operates it and where data comes from. Anonymous operations making inflammatory claims while connected to extremist networks are red flags for misinformation. Compare this to Kirsti Miller's open, identified work as a published researcher and Olympian.
These sites focus narrowly on trans athletes while largely ignoring systemic issues affecting all female athletes:
The Problem: If these organizations genuinely cared about female athletes' welfare, they would prioritize systemic issues affecting millions. Their narrow focus suggests a political agenda rather than genuine advocacy.
The major research findings above directly contradict SheWon's core narrative:
The Problem: When your core argument is contradicted by peer-reviewed, IOC-funded research, your credibility is fundamentally compromised. Yet SheWon continues spreading these claims uncritically.
SheWon claims to represent female athletes, but research shows otherwise.
The Problem: Studies confirm that the majority of female athletes have no problem with trans women competing in women's sports. The "protection" narrative manufactured by SheWon doesn't reflect what actual female athletes think or want. This is the same "divide and conquer" tactic used to justify bathroom bans and other discriminatory policies.
