In a landmark policy shift set to redefine the landscape of elite competition, the International Olympic Committee (IOC) has introduced sweeping eligibility regulations for women’s events, placing scientific verification at the center of participation criteria. Under the new framework, all athletes in female categories will undergo a one time genetic screening centered on the SRY gene, a marker typically linked to the Y chromosome.
The IOC says the move is aimed at preserving fairness, safety, and the integrity of women’s sport at the highest level. The policy effectively excludes transgender athletes from competing in women’s Olympic events while also tightening rules for athletes with Differences of Sex Development (DSD), who must now prove they do not gain performance advantages from elevated testosterone levels.
IOC President Kirsty Coventry stressed that the decision is rooted in science and expert medical guidance. She noted that at Olympic level, even the smallest physical edge can determine outcomes, making clear and consistent eligibility standards essential, while also calling for athletes to be treated with dignity and respect throughout the process.
The ruling has major implications for athletes such as Laurel Hubbard, a trailblazer as the first openly transgender Olympic weightlifter, and Imane Khelif, who has previously faced scrutiny over eligibility despite denying claims about her gender identity. Khelif, a Paris 2024 gold medalist, has indicated she is open to testing requirements but cautioned that fairness measures should not come at the expense of other female athletes.
The IOC’s decision follows similar steps by World Athletics and comes after high profile controversies involving Khelif and Lin Yu-ting, linked to disputed tests conducted by the now discredited International Boxing Association. While supporters view the policy as a decisive move to protect women’s competition, critics including dozens of advocacy groups argue it raises ethical concerns, especially as the rules will not apply to grassroots or recreational sport.
