Sports are usually about simple things like a ball, a net, or a finish line, but things have gotten complicated lately. People are arguing. Loudly. The central question—should trans women participate in women’s sports—has moved from niche academic circles to the front pages of every major news outlet and the floor of state legislatures. It’s a mess of emotions, biological data, and civil rights law.
Honestly, there isn't one "correct" answer that makes everyone happy.
If you look at the pool where Lia Campbell swam or the track where various high school athletes compete, you see the tension. On one side, you have the drive for inclusion. Everyone should get to play, right? On the other, there’s the preservation of a category—women’s sports—that was specifically created because of the physiological differences between the sexes.
The Biological Elephant in the Room
We have to talk about puberty. That’s the sticking point.
When a person goes through male puberty, their body changes in ways that aren't just about "feeling" a certain way; it’s about bone density, lung capacity, and muscle mass. Testosterone is a hell of a drug. It increases the size of the heart and the concentration of hemoglobin, which carries oxygen to the muscles. This is why the gap between elite male and female athletic performance generally sits between 10% and 12%, though in sports like weightlifting or sprinting, it can be even higher.
Dr. Emma Hilton, a developmental biologist, and Dr. Tommy Lundberg have published research suggesting that even after a year of testosterone suppression, trans women often retain significant strength and muscle advantages over biological females. They found that the loss of muscle mass is often only about 5% after twelve months of hormone therapy.
That’s a small number.
If a trans woman starts with 40% more muscle mass than a biological female peer, losing 5% doesn't exactly level the playing field. This is why organizations like World Athletics and World Aquatics (formerly FINA) changed their rules. They basically said, "Look, if you've gone through male puberty, you can't compete in the female category at the elite level."
Inclusion vs. Fairness: Can We Have Both?
The International Olympic Committee (IOC) used to have a very clear rule. It was all about testosterone levels. They required trans women to keep their testosterone below 10 nanomoles per liter for a year.

But then they changed their minds.
In 2021, the IOC shifted the responsibility to individual sports federations. Their new framework argued that there should be "no presumption of advantage." This caused a massive rift. Many athletes, like tennis legend Martina Navratilova and swimmer Sharron Davies, argued that this move ignored the basic reality of biological sex.
It’s a tough spot.
If you're a trans woman, you want to live your life authentically. You want to be part of the community that matches your identity. Exclusion feels like a slap in the face. It feels like being told you don't belong. But for many female athletes, seeing a competitor with a massive physiological head start feels like the death of the "fair play" promise that sports are built on.
The Legal Battleground and Title IX
In the United States, this isn't just a locker room debate; it's a legal one. Title IX was passed in 1972 to ensure that women had equal opportunities in education, which famously transformed women’s sports.
Now, the definition of "sex" in Title IX is under the microscope.
The Biden administration has sought to protect LGBTQ+ students by interpreting sex discrimination to include gender identity. This would mean that, in many cases, a blanket ban on trans women in sports could be seen as a violation of federal law. Conversely, dozens of states have passed their own laws specifically banning trans women and girls from female sports teams.
It’s a jurisdictional nightmare.

You’ve got high schoolers in Connecticut suing because they lost championships to trans athletes (Soule v. Connecticut Association of Schools). These girls argue that their dreams of scholarships and podiums are being sidelined. The court cases are slow, expensive, and incredibly personal.
Does the Level of Competition Matter?
Maybe the answer to should trans women participate in women’s sports depends on where the game is happening.
Think about it.
Is a local "just for fun" kickball league the same as the Olympic trials? Probably not. At the recreational level, the goal is social connection and health. Inclusion probably matters way more there than a 2% difference in sprinting speed. But when you get to the elite level—where seconds mean millions of dollars in endorsements—the math changes.
Some suggest "Open Categories."
British Cycling tried this. They created a "Female" category for biological women and an "Open" category for everyone else, including trans women and men. It’s an attempt to find a middle ground, but many trans advocates argue that "Open" is just a polite way of saying "Exiled." They want to compete as women, not in a separate bracket.
The Psychological Aspect
We can't ignore the human beings behind the headlines. Transgender youth experience incredibly high rates of depression and suicide. For many, sports are a lifeline. Being part of a team provides a sense of belonging that is hard to find elsewhere.
When we talk about policy, we're talking about kids.

But we’re also talking about the girls who have trained since they were five years old. They’ve sacrificed weekends, social lives, and physical health for a shot at a title. When they feel the game is rigged, they lose more than a trophy; they lose faith in the system.
It’s a collision of two vulnerable groups.
Moving Toward a Solution
So, where do we actually go from here?
There is no magic wand. However, the data suggests we need more specific research. Most studies on trans athletes are small. We need long-term, peer-reviewed data on how hormone therapy affects performance in specific sports over three, five, or ten years.
Policy should probably be sport-specific.
A trans woman might have a massive advantage in powerlifting but a negligible one in equestrian sports or shooting. A one-size-fits-all rule usually fits nobody.
Actionable Steps for the Future
If you are a coach, an athlete, or a parent navigating this, here is how the landscape is shifting:
- Check Local and State Laws: Before making any decisions, you have to know the specific legal requirements in your state. The map is changing monthly as new legislation is introduced and challenged in court.
- Consult Governing Bodies: If you’re at the competitive level, look at the specific International Federation (IF) rules. World Athletics, World Aquatics, and the UCI (cycling) have very different standards than the NCAA.
- Prioritize Privacy: Regardless of the side of the debate you're on, the medical history of minors should remain private. Outing students helps no one and creates a hostile environment.
- Focus on Nuance: Avoid the "all or nothing" rhetoric. Acknowledge that it is possible to support trans rights while also believing that the female sports category requires biological protections. These two ideas can exist in the same brain.
- Advocate for More Funding: We need more categories, more teams, and more research. The "scarcity mindset"—the idea that there’s only one small pie to share—is what makes this conflict so bitter.
The debate over should trans women participate in women’s sports isn't going away. It requires us to be more precise with our language and more honest about the trade-offs we're willing to make. Whether the goal is total inclusion or absolute biological fairness, someone is usually left feeling like they lost. The work now is to minimize that loss without destroying the integrity of the game itself.
