IOC Backs Genetic Screening For Women’s Olympic Eligibility At LA28

The International Olympic Committee has signed off on a major shift that will redefine women’s competition at the Games. From the 2028 Los Angeles Olympics onward, eligibility will hinge on a single factor: biology, verified through testing.

Under the new IOC women's eligibility policy, athletes entering female categories must undergo a one-time genetic check for the SRY gene. It is a marker typically linked to male sex development. 

The process is straightforward, involving a one-time genetic test conducted through a cheek swab, saliva sample, or blood draw, unless further verification is required. Officials say the measure is intended to ensure clarity and fairness.

What the new Olympic rule means

Those who test negative will be cleared permanently for women’s events. There will be no repeated checks, no yearly reviews. A clean, one-time decision should just work.

On the other side, athletes who return a positive result for the gene will not compete in women’s categories at IOC events. There are limited exceptions. Cases such as Complete Androgen Insensitivity Syndrome may still be reviewed individually.

Still, the message is firm.

The debate around inclusion and fairness has lingered for years. This move draws a line.

IOC President Kirsty Coventry didn’t dodge the issue. She pointed to competitive balance and athlete safety, stressing that performance advantages tied to male biology cannot be ignored in elite sport.

The groundwork for this decision stretches back months. Consultations ran from late 2024 into early 2026. Medical experts weighed in. Legal voices added their take. More than 1,100 athletes shared feedback.

At the centre of it all sits SRY gene testing Olympics rules, now positioned as the most reliable method available. Less intrusive, more precise, according to the IOC’s working group.

And yet, reactions are already building.

Some federations are expected to follow quickly. Others may take their time. The IOC has made it clear this applies strictly to elite competition, not grassroots sport.

Still, one thing is certain. With SRY gene testing Olympics standards locked in for LA28, the conversation around fairness in sport just entered a new phase.
