The International Olympic Committee (IOC) has announced a sweeping new policy that will bar transgender women from competing in all female categories at the Olympic Games and other IOC-sanctioned events.
The new eligibility rules, set to take effect from the 2028 Los Angeles Olympics, restrict participation in women’s events strictly to biological females.
Determination will be based on a one-time genetic test, according to the IOC’s 10-page policy document released after an executive board meeting.
The IOC says the decision aims to “protect fairness, safety and integrity in the female category,” adding that the policy will not be applied retroactively and will not affect grassroots or recreational sports programs.
This comes despite the Olympic Charter emphasizing that access to sport is a fundamental human right.
The move aligns with recent political developments, including an executive order by Donald Trump focused on women’s sports, issued in the build-up to the 2028 Games in Los Angeles.
IOC President Kirsty Coventry, the first woman to lead the organization in its 132-year history, had prioritized the review of female eligibility rules shortly after taking office. She pushed for a unified global policy instead of allowing individual sports federations to set their own guidelines, which had previously led to inconsistencies.
Before the 2024 Paris Olympics, several major sports bodies, including athletics, swimming, and cycling, had already introduced bans on transgender women who had undergone male puberty.
The IOC’s latest stance consolidates that direction across all Olympic disciplines.
The policy also affects athletes with differences in sex development (DSD), including two-time Olympic champion Caster Semenya, whose eligibility has long been debated due to naturally elevated testosterone levels.
According to the IOC’s findings, individuals born male experience three key testosterone surges, before birth, during infancy, and at puberty, which contribute to lasting physical advantages in strength, endurance, and power.
These biological differences were cited as a central reason behind the new restrictions.
Despite the sweeping nature of the decision, it remains unclear how many transgender women have competed—or are currently competing—at the Olympic level.
Notably, no openly transgender woman competed at the Paris 2024 Games.
However, past cases have kept the issue in the spotlight. New Zealand weightlifter Laurel Hubbard made history at the Tokyo 2020 Olympics (held in 2021) as the first openly transgender woman to compete at the Olympics.
Although she did not medal, her participation sparked global debate on fairness and inclusion.
Similarly, Canadian soccer player Quinn, who identifies as non-binary, won gold at Tokyo 2020, highlighting the growing diversity in athlete identities, though Quinn competed in a category aligned with birth sex.
The IOC’s latest decision now marks a significant shift toward stricter regulation, signaling the end of a more flexible era in gender eligibility at the Olympic Games.
