Olympic women’s sport to be limited to biological females
The IOC will require a one-time SRY gene test for all female athletes, reversing its 2021 policy.
The International Olympic Committee (IOC) has enacted a sweeping policy shift that will bar transgender women and athletes with Differences in Sexual Development (DSD) from competing in female categories at the Olympic Games. Announced on March 26, 2026, the new rule mandates that eligibility for any female event is now limited to 'biological females,' determined by a one-time SRY gene screening. This test, which can be conducted via saliva, cheek swab, or blood sample, will be implemented for the 2028 Los Angeles Games, effectively reversing the 2021 framework that delegated policy decisions to individual sports federations.
IOC President Kirsty Coventry stated the policy is 'based on science and has been led by medical experts,' framing it as a move toward universal standards. The decision marks a significant departure from the previous, more decentralized approach and establishes a single, biology-based criterion for participation in women's Olympic sports. This change is poised to have immediate and profound implications for athlete eligibility, team compositions, and the ongoing global debate over fairness and inclusion in elite athletics.
- The IOC will require a one-time SRY gene test (via saliva, cheek swab, or blood) to determine 'biological female' status for the 2028 Games.
- The new policy reverses the 2021 rules that allowed individual sports federations to set their own eligibility criteria for transgender athletes.
- The change excludes both transgender women and athletes with Differences in Sexual Development (DSD) from competing in Olympic women's sports.
Why It Matters
This establishes a new, biology-based global standard for women's elite sports, directly impacting athlete eligibility and the inclusion debate.
