The International Olympic Committee has announced new eligibility rules that will restrict women's sport categories to biological females, with the policy set to take effect at the 2028 Los Angeles Olympics.

The new female-only eligibility policy will be enforced through SRY gene screening, according to reports. The SRY gene, located on the Y chromosome, is typically used to determine biological sex at the chromosomal level.

The announcement comes amid ongoing debates about transgender participation in women's sports across various levels of competition. The IOC's decision represents a significant policy shift that will affect eligibility criteria for female athletes competing in Olympic events.

The policy change will first be implemented at the 2028 Summer Olympics in Los Angeles, giving sports organizations and athletes time to prepare for the new requirements. The IOC has not yet released detailed implementation guidelines or addressed how the screening process will be conducted.

The decision has generated discussion among athletes, sports organizations, and advocacy groups about the balance between inclusion and competitive fairness in women's sports. The new rules will apply specifically to women's sport categories within Olympic competition.
