IOC Mandates SRY Gene Screening for Women Events Starting 2028
Landmark Decision: IOC Restricts Women Events to Biological Females
The International Olympic Committee Executive Board has approved a new regulation restricting women Olympic events to biological females only, verified through SRY gene screening.
Key Details
- Effective: 2028 Los Angeles Olympics onward
- Method: SRY gene test, most accurate and least invasive biological sex verification
- Scope: All IOC events; federations expected to follow
- No retroactivity: Does not apply to past competitions or grassroots sports
- One-time test: Athletes need only screen once in their lifetime
IOC President Statement
President Kirsty Coventry stated that in the Olympics even the smallest difference can determine the outcome, therefore biological males competing in women categories is clearly unfair. She emphasized every athlete should be treated with dignity and respect.
Impact
Athletes testing positive for the SRY gene will be ineligible for women events but may compete in men events, mixed-gender events in designated male slots, open categories, or any events not divided by sex.
The IOC stated extensive consultation reached a consensus: in all sports dependent on strength, explosiveness, and endurance, biological males have significant advantages. Ensuring fairness and athlete safety requires eligibility based on biological sex.
