IOC approves genetic-based ban on transgender women in Olympic events

The IOC adopted a non-retroactive eligibility policy that bars transgender women from female Olympic categories and other IOC events, determined by a one-time SRY gene screening, effective for the 2028 Los Angeles Games. The move aims to protect fairness and safety in the female category, and also limits athletes with certain differences in sex development (DSD); the document notes that being born male and puberty-related testosterone can confer advantages in strength, power, and endurance.
