The International Olympic Committee (IOC) has announced a sweeping new policy that will prohibit transgender women from competing in women’s events at the Olympic Games, beginning with the 2028 Summer Olympics in Los Angeles.
Under the new rules, eligibility for the female category will be limited to athletes classified as biological females, determined through a one-time genetic screening test that detects the presence of the SRY gene, a marker typically associated with male sex development. The test can be conducted through non-invasive methods such as saliva or cheek swabs.
IOC President Kirsty Coventry said the decision was based on scientific and medical evidence and is intended to ensure fairness and safety in women’s competition. Officials argue that athletes who have undergone male puberty may retain physical advantages, even after transitioning.
The policy follows an extended review process and marks a significant shift from previous IOC guidelines, which allowed individual sports federations to set their own rules regarding transgender participation.
The change has sparked immediate global debate. Supporters—including some athletes and advocacy groups focused on women’s sports—have praised the decision as necessary to protect competitive integrity.
However, critics, including LGBTQ+ organizations and some international sports bodies, argue the policy is discriminatory and raises ethical concerns about privacy and inclusion. They warn that mandatory genetic testing could stigmatize athletes and lead to invasive scrutiny.
The IOC said the new rules will apply only to elite-level Olympic competition and will not extend to amateur or recreational sports.
The decision comes amid broader political and sporting debates worldwide over transgender participation in athletics. Several international federations have already enacted similar restrictions in recent years, and U.S. policies have also moved in the same direction ahead of the Los Angeles Games.
As preparations for the 2028 Olympics continue, the policy is expected to face ongoing legal, scientific, and ethical scrutiny, with its long-term impact on athletes and global sport still unfolding.
