IOC bars transgender women from women's Olympic events, introduces SRY testing

The International Olympic Committee announced a policy banning transgender women and athletes with differences in sex development (DSD) from the female category at the 2028 Los Angeles Games and future Olympics, requiring a one-off SRY gene test to determine biological sex. The policy, described as science-based and focused on fairness and safety, applies to elite competition and would mean athletes must be screened only once in their lifetime with education and counselling provided. The IOC argues male puberty provides performance advantages in many events, reinforcing the need for a sex-based female category, and notes past cases such as Laurel Hubbard and Imane Khelif as context.
