Transgender women athletes are now excluded from women's events at the Olympics after the IOC agreed to a new eligibility policy on Thursday which aligns with U.S. President Donald Trump's executive order on sports ahead of the 2028 Los Angeles Games. "Eligibility for any female category event at the Olympic Games or any other IOC event, including individual and team sports, is now limited to biological females," the International Olympic Committee said, to be determined by a mandatory gene test once in an athlete's career.

It is unclear how many, if any, transgender women are competing at an Olympic level. No woman who transitioned from being born male competed at the 2024 Paris Summer Games, though weightlifter Laurel Hubbard did at the Tokyo Olympics in 2021 without winning a medal. The eligibility policy that will apply from the LA Olympics in July 2028 "protects fairness, safety and integrity in the female category," the IOC said. "It is not retroactive and does not apply to any grassroots or recreational sports programs," said the IOC, whose Olympic Charter states that access to play sport is a human right.
