Track and field’s latest rulebook update might read more like a genetic instruction manual than an athletic guideline. The international governing body for the sport, World Athletics, just announced a September 1 deadline for female athletes to undergo mandatory gene testing if they want a shot at competing in the upcoming World Championships in Tokyo. The cheek swab or dry blood-spot test isn’t optional—it’s now the new gatekeeper of elite-level participation for women.
Under these controversial rules, athletes with what the sport calls “Differences in Sex Development” (DSD) are being asked to prove that they’re “biologically female”—a requirement defined by the presence or absence of a Y chromosome. If they don’t pass, they don’t compete. “We are saying, at elite level, for you to compete in the female category, you have to be biologically female,” declared World Athletics president Sebastian Coe, as if that closed the case. But let’s be clear: this isn’t just about chromosomes—it’s about control, access, and identity.
Caster Semenya and the Long Road to Inclusion
The issue exploded into the public eye more than a decade ago when South African runner Caster Semenya dominated the 800 meters as a teenager. With her powerful stride and record-breaking times, Semenya soon found herself not celebrated, but scrutinized. She became the unwilling face of a sport’s attempt to draw a genetic line between genders.
In July, Semenya scored a legal victory at the European Court of Human Rights, which found that she was denied a fair hearing when she initially challenged the rules. Still, the judgment didn’t overturn the regulations. Now at 34, with her career in limbo and World Athletics doubling down on DNA, Semenya’s battle continues—but this time it may return to the Swiss courts. Her case remains a chilling symbol for the impact of these policies on women who don’t conform to narrow definitions of gender.
A Slippery Slope for Trans and Intersex Athletes
While the new policy affects DSD athletes directly, World Athletics has merged its DSD and transgender eligibility rules into one controversial framework. Notably, the body claims there are currently no transgender women competing at the elite international level under the new regulations, allowing it to avoid deeper scrutiny—for now.
The so-called “transitional provisions” let a very limited group of DSD athletes continue competing—if they’re taking medication to suppress their natural testosterone levels. Translation? You’re welcome on the track, but only if you medicate your body to fit our template.
Despite assurances that the new SRY test is “extremely accurate,” critics argue that this isn’t about science—it’s about politics and outdated ideas of gender. For the LGBTQ community, particularly trans and intersex athletes, this represents yet another attempt to police bodies under the guise of fairness. Instead of celebrating diversity, the sport’s gatekeepers are reducing gender to a code in our cells.
LGBTQ Athletes Left in the Dust
This gene-test deadline sends a loud, unmistakable message to LGBTQ athletes: your identity is not yours to define. In a world where gender is increasingly understood as a spectrum, track and field is clinging to rigid binaries enforced through medical tests. The psychological toll of being told to “prove” your gender, especially with global scrutiny and competitive pressure, is profound.
For LGBTQ advocates and athletes, this rule is more than bad policy—it’s a warning. The need for inclusive, scientifically-sound, and compassionate regulations has never been more urgent. Sports are supposed to be about talent, discipline, and heart—not cheek swabs and gene codes.
But for now, if you’re a woman who wants to run in Tokyo, you better get your chromosomes in order.
