The IOC has approved a new policy on women's eligibility in Olympic sports that will be implemented from Los Angeles 2028. Eligibility in women's events will be linked to a one-time screening for the SRY gene, the organization announced on March 26, 2026.
El International Olympic Committee has fundamentally changed its eligibility framework for the female category in Olympic sport.
The new policy, approved by the IOC Executive Board, will come into effect starting with the Games of Los Angeles 2028 and it will not be retroactive.
In practice, the organization then establishes a common criterion for its events: the female category It will be reserved for athletes considered biologically female based on a screening of SRY gene.
The decision affects the entire Olympic program and also other IOC events, both in individual and team sports.
According to official noteThe goal is to protect the equity, security and integrity of the women's category. The IOC adds that this policy supersedes its previous positions on this matter, including the 2021 framework focused on equity, inclusion and non-discrimination based on gender identity and sex variations.
What exactly has the IOC approved regarding the women's category?
The main novelty is the implementation of a single test for the SRY gene to determine eligibility in the female category.
The IOC maintains that the presence of this gene, usually associated with the Y chromosome and male sexual development, offers a “very precise” basis for this purpose. Sample collection can be done by saliva, oral swab, or blood.
The organization explains that if an athlete tests negative in that screening, she will permanently meet the eligibility criteria to compete in the female category, unless there is some reason to think there was an error in the reading.
At the same time, it contemplates limited exceptions, such as some cases of complete androgen insensitivity syndrome (CAIS) or other differences in sexual development where there is no anabolic benefit or performance advantage linked to testosterone.
For those who do not meet that criterion, the IOC indicates that they will be able to continue competing in male, open or mixed categories when they exist.
This is an important distinction, because the new framework does not propose expulsion from the sport, but rather a eligibility reassignment within the categories recognized by each competition.
How the new IOC policy has been built
The IOC frames this decision within a review developed between September 2024 and March 2026.
Specialists participated in that process in endocrinology, sports medicine, women's health, ethics and law, in addition to medical officers from international federations.
The conclusion reached by the organization is that male biological characteristics provide an advantage in sports where physical attributes are a factor. strength, power, and endurance.
There was also consultation with athletes. The IOC indicates that it received over 1.100 responses in an online survey, as well as individual interviews and work with the Athletes' Commission.
According to the organization itself, this process resulted in broad support for clear, consistent rules based on scientific criteria, along with the demand to protect the dignity, privacy and well-being of the affected athletes.
Meanwhile, this line had already appeared in other sports. World Athletics In July 2025, it announced its own unique SRY gene test for female athletes to compete in its world championships, effective September 1 of that year.
This precedent helps to understand that the IOC is not entering this debate from scratch, but in a context where several international federations were already tightening their criteria.
What changes for athletes and federations?
In the short term, the greatest effect will be on paving the way towards LA28.
The IOC is asking international federations and other sports bodies to adopt this policy when applying eligibility rules related to Olympic events. This means that much of the practical implementation will now fall to each individual federation, which will have to set its own rules. protocols, education, support and confidentiality channels.
The IOC insists that the process must be accompanied by medical advice, mental health support, and privacy protection. Kirsty Coventry, president of the organization, defended that every athlete should be treated with dignity and respect, and stressed that screening should only be done once in a lifetime.
In endurance sports like triathlon, where the debate often focuses on the interaction between physiology, performance, and competitive equityThe IOC's decision adds a much more defined Olympic framework.
It doesn't automatically change the rules of each federation outside of IOC events, but it does set a clear direction for the cycle towards 2028.
A change with support and also with opposition
The new policy has not been without criticism. In the hours following the announcement, objections emerged from human rights organizations, scientific groups, and voices linked to sports, questioning both the scientific basis of the screening and its implications for Privacy, inclusion and treatment of trans, intersex and DSD athletes.
That point explains why the IOC's decision will continue to generate debate in the coming months.
On one hand, the organization presents it as a measure to protect women in the Olympic elite. On the other, its detractors believe it opens a new front of conflict. legal, ethical and scientific.
What is clear today is that the IOC has abandoned the 2021 framework and set a new benchmark for access to women's competition in its events from Los Angeles 2028.
Why this IOC decision also matters to triathlon
Although the announcement does not specifically refer to triathlon, it does affect the Olympic ecosystem in which this sport operates.
World triathlon And national federations will have to observe how the application is implemented in events under the Olympic umbrella, especially during the qualification for LA28 and in defining criteria for the female category.
In a sport where seconds and watts Separating the podium and the diploma, the debate about eligibility will remain very much present.
What's relevant, for now, is the change in framework. The IOC no longer leaves this area open to general interpretations of inclusion and non-discrimination, but is committed to a more restrictive, common rule based on a single genetic test.
That will be the starting point of the next Olympic cycle.
