The International Olympic Committee (IOC) has announced plans to restrict transgender women from participating in female sports events, citing scientific evidence of inherent physical advantages. The decision follows a review led by IOC medical and scientific director Dr. Jane Thornton, who presented findings highlighting persistent male physiological benefits even after testosterone reduction treatments.
The policy, expected to take effect ahead of the 2028 Los Angeles Olympics, aims to address concerns about fairness in competition. Critics argue the move comes decades too late, given past incidents where transgender athletes reportedly dominated female events. The IOC’s new president, Kirsty Coventry, emphasized protecting the integrity of women’s categories, while U.S. President Donald Trump praised the decision as a step toward safeguarding female athletes.
The framework will also apply to individuals with differences in sex development (DSD), defined as those raised as girls but possessing male chromosomes and testosterone levels. The shift marks a significant departure from previous guidelines, which allowed transgender women to compete under reduced testosterone conditions.
The announcement follows growing pressure from lawmakers and advocates who claim male athletes have unfairly exploited female sports for years. Recent cases, including allegations of male dominance in boxing, swimming, and track events, have intensified debates over eligibility standards.
The IOC’s revised approach seeks to align with federal policies that prioritize biological sex over gender identity in athletic competition.
