Key Takeaways:
- Years of decentralized rules created confusion and uneven standards across competitions.
- The IOC’s new policy marks a decisive shift back toward biological definitions and common sense in women’s sports.
- The decision reinforces fairness as the core principle behind meaningful athletic competition.
Why do we honor athletes like Jackie Joyner-Kersee, the first American woman to win gold in both the long jump and heptathlon? Why do we retell stories of watching Mary Lou Retton score a perfect 10 on two vaults at the 1984 Olympic Games? Why do we admire Katie Ledecky’s record-breaking accomplishments and nine Olympic gold medals?
Because of what the Olympics represents.
At its best, the Olympics are straightforward: the best in the world competing on a level playing field. There are no curves, no shortcuts, and no participation trophies.
The best male athletes have always faced off against each other, and the same for female athletes. Why?
Because deep down, everyone understands the starting point for fairness: male athletes possess real, God-given physical advantages in sports. And pretending otherwise doesn’t level the field; it tilts it against women who’ve earned their place. Ignoring that fact has robbed vast numbers of female athletes of opportunities they’ve earned and deserve.
Jesse Owens famously dominated the 1936 Olympics, winning four gold medals in track and field. He won the 100-meter dash with a time of 10.3 seconds. American Helen Stephens won the 100-meter race on the women’s side, clocking in at 11.5 seconds.
Owens was clearly faster than Stephens, but so was Bernard Marchand of Switzerland, who finished at 11.2 seconds, which wasn’t fast enough to advance even to the quarterfinals for the men’s competition.
Denying science and biology means denying reality, and that has very tangible consequences.
Olympic officials knew this in 1936 but appeared to forget the importance of science and biology over the ensuing years.
The IOC’s rule change jeopardized women
In 2015, the International Olympic Committee (IOC) decided to allow men to compete in women’s sports, starting with Laurel Hubbard in the 2020 Olympics.
Then, in 2021, the IOC changed its previous testosterone suppression requirement and allowed the governing body of each sport “to determine how an athlete may be at a disproportionate advantage against their peers, taking into consideration the nature of each sport.”
This was not a step toward increased fairness. In fact, the IOC’s inaction decreased fairness by further allowing males to compete against females.
When the IOC pointedly refused to acknowledge the fundamental truth that male and female athletes are different, it’s young women who paid the price—and not just at the Olympics.
As the governing body of the most renowned sporting event in the world, the IOC wields tremendous influence. When the IOC lowers standards, that influence inevitably trickles down, helping pave the way for similarly harmful policies at lower levels of sport.
Alliance Defending Freedom has been helping push back against these harmful policies that allow boys to compete in girls’ sports. ADF supported the states of Idaho and West Virginia , eventually culminating at the Supreme Court in the cases of Little v. Hecox and State of West Virginia v. B.P.J. in January 2026. In both cases, Idaho and West Virginia were defending state laws that aim to protect girls from having boys compete in their sports. It’s crucial, commonsense protection.
And thankfully, after years of muddled direction, common sense appears to have finally prevailed at the IOC.
The IOC changes course
In late March, the IOC announced that it had implemented a new policy designed to ensure that “for both individual and team sports, eligibility for any female category is limited to biological females.”
Female category eligibility will now be determined by a simple, one-time test (the IOC notes that a saliva or cheek swab will suffice) to determine the presence of the SRY gene. The IOC “considers that the presence of the SRY gene is fixed throughout life and represents highly accurate evidence that an athlete has experienced male sex development.”
Once a female passes the test, she is set for life and will never have to take another SRY test again, barring a rare exception of there being reason to believe that an error occurred during the test. This policy will begin with the forthcoming 2028 Olympics and will not apply retroactively.
“As a former athlete, I passionately believe in the rights of all Olympians to take part in fair competition,” IOC President Kirsty Coventry said. “The policy that we have announced is based on science and has been led by medical experts. At the Olympic Games, even the smallest margins can be the difference between victory and defeat.
“So, it is absolutely clear that it would not be fair for biological males to compete in the female category. In addition, in some sports it would simply not be safe.”
Women deserve fairness in sports
Coventry is correct, and science is and has been clear on this matter. Multiple studies—never mind the evidence before your eyes—clearly show that male athletes have a significant physical advantage over female athletes in nearly every sport. Yet the IOC’s inaction for years had left the decision up to the governing bodies of each sport.
The IOC’s newfound change of heart is both welcome and long overdue. For years, it deferred responsibility, allowing confusion and inconsistency to take root across international sport. By finally drawing a clear, science-based line, the committee is sending a signal to the rest of the athletic world that fairness is not negotiable and never should have been.
At its core, this decision is about restoring what women’s sports were always meant to guarantee: a fair and safe space for female athletes to compete, excel, and be recognized. When those boundaries are broken, it’s women who bear the cost of lost opportunities, of compromised safety, and of the quiet erosion of trust in the system.
By reestablishing clear, biologically grounded standards, the IOC is giving female athletes back the certainty that their competition is truly their own and that their achievements will stand on a level playing field.
And it’s about time.
