Briefly

On March 26 the IOC approved new rules for participation in women's competitions at the Olympic Games: starting from Los Angeles 2028 only biological women will compete in women's disciplines. Eligibility will be determined by a single sex test, to be carried out "once in a lifetime." The policy replaces previous recommendations, is not retroactive, and does not apply to mass or recreational sport.

Why the IOC changed its approach

The IOC's official rationale is based on medical examinations and the objective of guaranteeing equality and safety in women's sports. The organization's statement notes that the presence of the SRY gene is considered an indicator of male biological development and does not change over a lifetime — this is the basis for the selection methodology.

"At the Olympic Games even the smallest difference can be decisive between victory and defeat. So it is absolutely obvious that it would be unfair if biological men competed in the women's category. Moreover, in some sports it would simply be dangerous."

— Kersti Coventry, President of the IOC

Criticism and experts' concerns

At the same time, a number of scientists and legal experts emphasize that SRY or a single biomarker is an oversimplification of complex biology. Physiological advantage in sport is determined by many factors (muscle mass, hormonal profile, organ development, training). Analysts point out that moving to testing based on a single marker could trigger legal claims and medical debates, as well as provoke political reactions in different countries.

Context and previous steps

The IOC decision comes against the backdrop of several political initiatives: in 2025 in the United States executive orders were signed that limited the participation of transgender women in women's sport at the national level. Also, in October 2025 the United Nations, according to reports, published data on cases where transgender athletes affected the distribution of medals — one of the factors that pushed the discussion to the global level.

What this means for Ukraine

For Ukrainian athletes and federations the IOC decision has practical consequences: national trials, anti‑doping procedures and eligibility protocols will have to be brought into line with the new rules ahead of the 2028 Olympic Games. This will require:

• prompt decisions by the National Olympic Committee and federations,
• legal preparedness in case of external lawsuits or appeals,
• an information campaign for athletes, coaches and medical staff explaining the new criteria.

Possible consequences and scenarios

The first years after the policy's implementation will likely be marked by legal battles and scientific debates. Possible scenarios include disagreements between national federations and the IOC, attempts to challenge the selection methodology in international courts, and the adoption of similar rules at the level of continental games. Ukraine could use this time to strengthen its selection system and the protection of its female athletes' rights.

Conclusion

The IOC's decision is not just a sporting rule but a signal that global sport is trying to restore standards for women's competition through medical and legal mechanisms. For Ukraine it is important to act prudently: transform internal procedures, ensure transparency and prepare for potential legal and political challenges. The next 12–36 months will show how quickly the sporting world can reconcile fairness, safety and individual rights.
