- The International Olympic Committee will restrict the women’s category to biological females starting in 2028.
- Athletes must undergo a single sex test to determine eligibility for future Olympic competitions.
- The new policy aims to ensure fairness and safety by using genetic screening for participants.
Starting with the Los Angeles Games in 2028, the International Olympic Committee will implement a strict policy regarding the female category. Participation will be reserved for biological females only. This decision follows years of intense global debate regarding the inclusion of transgender women and individuals with differences in sexual development in elite sports.
To enforce these rules, the organization will introduce a once-in-a-lifetime genetic screen. This test specifically looks for the SRY gene, which is found on the Y chromosome and triggers the development of male physical traits. Anyone testing positive for this gene will be excluded from female events to maintain competitive integrity across the Games.
President Kirsty Coventry explained that medical expert guidance drove this policy shift. She noted that even minimal physical differences can determine podium finishes in high-stakes environments. Therefore, allowing biological males to compete against females is considered unfair and potentially unsafe in several sporting disciplines regulated by the committee.
Athletes who do not meet the female criteria are not entirely banned from the Olympics. They remain eligible for male categories or any open classifications that do not segregate by sex. This approach creates a universal standard, replacing the previous system where individual sports federations set their own varied and sometimes conflicting eligibility requirements.
The policy includes a specific exemption for athletes with complete androgen insensitivity syndrome. Because these individuals do not undergo male puberty, they may still qualify for women’s sports. However, most other conditions involving male XY chromosomes, such as those seen in famous past cases, will now result in disqualification from the female division.
Support for the move comes from those prioritizing fairness and safety. They argue that genetic testing is more objective and humane than requiring athletes to medically suppress their testosterone levels. Conversely, critics warn the tests are invasive and potentially psychological harmful, suggesting that reducing sex to a single gene ignores the complexity of human biology.
The committee reached this conclusion after 18 months of scientific data review and consultation with over 1,100 athletes. This research confirmed a consensus that male biological traits provide a significant performance advantage in power-based sports. These findings will not be applied retrospectively, meaning previous Olympic medals and records will remain unchanged for now.
