The International Olympic Committee on Thursday announced it will not allow transgender women from competing in female events at the Olympics.
“For all disciplines on the Sports Program of an IOC event, including individual and team sports, eligibility for any Female Category is limited to biological females,” reads the new policy.
The policy states “eligibility for the Female Category is to be determined in the first instance by SRY Gene screening to detect the absence or presence of the SRY Gene.”
“On the basis of the scientific evidence, the IOC considers that the SRY (sex-determining Region Y) Gene is fixed throughout life and represents highly accurate evidence that an athlete has experienced or will experience male sex development,” it reads. “Furthermore, the IOC considers that SRY Gene screening via saliva, cheek swab or blood sample is unintrusive compared to other possible methods. Athletes who screen negative for the SRY gene permanently satisfy this policy’s eligibility criteria for competition in the Female Category.”
The policy states the test “will be a once-in-a-lifetime test” unless “there is reason to believe a negative reading is in error.”
The new regulation will be in place for the 2028 Summer Olympics in Los Angeles.
“I understand that this a very sensitive topic,” said IOC President Kirsty Coventry on Thursday in a video. “As a former athlete, I passionately believe in the rights of all Olympians to take part in fair competition.”
“The policy that we have announced is based on science and it has been led by medical experts with the best interests of athletes at its heart. The scientific evidence is very clear: male chromosomes give performance advances in sport that rely on strength, power, or endurance,” she added. “At the Olympic Games, even the smallest margins can be the difference between victory and defeat. So, it is absolutely clear that it would not be fair for biological males to compete in the female category. In addition, in some sports it would simply not be safe.”
Laurel Hubbard, a weightlifter from New Zealand, in 2021 became the first trans woman to compete at the Olympics.
Imane Khelif, an Algerian boxer, won a gold medal at the 2024 Summer Olympics in Paris. Khelif later sued JK Rowling and Elon Musk for cyberstalking after they questioned her gender identity.

President Donald Trump in February 2025 issued an executive order that bans trans women and girls from female sports teams in the U.S.
The U.S. Olympic and Paralympic Committee last July banned trans women from competing in female sporting events. Republican lawmakers have demanded the IOC ban trans athletes from women’s athletic competitions.
“I’m grateful the Olympics finally embraced the common sense policy that women’s sports are for women, not for men,” said U.S. Sen. Tom Cotton (R-Ark.) on X.
An IOC spokesperson on Thursday referred the Washington Blade to the press release that announced the new policy.
