IOC bans transgender women from women’s Olympics events
The International Olympic Committee (IOC) has approved a significant new policy that will restrict participation in women’s events at the Olympic Games to biological females.
The rule, announced ahead of the 2028 Los Angeles Olympics, introduces mandatory eligibility screening based on the presence of the SRY gene, a genetic marker typically associated with male sex development.
According to the IOC, the policy is aimed at “protecting fairness, safety and integrity” in women’s competition at elite level sport.
What the New Policy says
Under the updated framework:
- Participation in women’s Olympic events is limited to athletes classified as biological females
- Eligibility is determined through a one-time SRY gene screening test
- The rule applies to all IOC-sanctioned competitions, including team and individual sports
- It is not retroactive and does not affect grassroots or recreational sports
The IOC described the genetic test as the “most accurate and least intrusive” method currently available.
Alignment with U.S. Policy
The decision comes amid growing political pressure globally and aligns in part with policy direction in the United States under Donald Trump, who previously signed an executive order focused on restricting transgender participation in women’s sports.
With Los Angeles set to host the 2028 Games, the intersection of sport governance and national policy has become increasingly prominent.
Impact on Athletes and Past Participation
It remains unclear how many transgender women are currently competing at Olympic level. At the Tokyo 2020 Olympics, Laurel Hubbard became the first openly transgender woman to compete in the Games, though she did not win a medal. No transgender women competed at the Paris 2024 Olympics.
DSD Athletes Also Affected
The new policy also has implications for athletes with differences in sex development (DSD), including Caster Semenya, a two-time Olympic champion.
Semenya has previously challenged eligibility rules related to naturally high testosterone levels, taking her case to the European Court of Human Rights. While she secured a legal victory regarding procedural fairness, the underlying sporting regulations remained unchanged.
Leadership Push for a Unified Rule
IOC president Kirsty Coventry has prioritised the creation of a clear, universal policy after years of allowing individual sports federations to set their own standards.
Speaking on the decision, she emphasised the fine margins in elite competition and the importance of maintaining a level playing field in women’s sport. Her leadership marks a shift toward centralised regulation on one of the most debated issues in modern athletics.
Scientific basis behind the decision
The IOC’s policy document outlines its position that biological differences linked to male development can provide lasting performance advantages. It highlights three key testosterone exposure phases:
- Development before birth
- Early infancy
- Puberty and adulthood
According to the IOC, these factors contribute to differences in strength, endurance, and power — particularly relevant in high-performance sport.
Growing Debate and Criticism
The introduction of mandatory gene testing is expected to generate strong reactions from human rights groups, medical experts, and athlete advocacy organisations. Critics argue that such policies raise concerns around Privacy and bodily autonomy, Inclusion in sport and the complexity of sex and gender biology.
Supporters, however, see the move as necessary to preserve competitive fairness in women’s categories.
What happens next
The policy will come into effect for the 2028 Olympic cycle, making it one of the most consequential governance changes in recent Olympic history.
As global sport continues to navigate the balance between inclusion and fairness, the IOC’s decision is likely to influence policies across international federations and national governing bodies.
