Let’s have a civil discussion about transgender girls playing on high school sports teams. (Adult sports teams are outside the scope of this post.)

I’ve spent some time researching this, and comparing policies in different states. Please read the post before commenting. The goal is education and polite discussion of legitimate concerns, not having a culture war.

Alright, let’s start with two hypotheticals for illustrations, and then get into policies, laws, and gender-affirming care.

The Hypotheticals 

Here’s our first hypothetical: Michael is a mediocre athlete. He’s gone through puberty and, at age 17, is about 5’11” and has a decent amount of upper body strength, but he’s just not standing out while playing linebacker on the high school football team. Michael wants to excel at sports, so he hatches a plan. His senior year, he tells everyone his name is now Michelle and his pronouns are she/her. Within a week, she gets on the girls volleyball team and absolutely dominates. Michelle wins a scholarship to college for girls volleyball. She’s shut out the other girls on the team because she’s biologically a boy, which makes her a better athlete than cisgender girls.

Here’s our second hypothetical: Jack has always known he was really a girl and has supportive parents. Jack, who wants to be called Jill, started puberty blockers at twelve to give her some time to consider if she really was trans. A year later, after she’s convinced her parents that this really is her truth, she starts gender-affirming hormone therapy at thirteen, just before she starts eighth grade. Jill never went through male puberty. At age 14, she’s been on estrogen and a testosterone blocker for a year and she wants to try out for the freshman girls sports team. She’s at average height, strength, and speed for a 14-year-old girl, and no one even knows she’s trans unless she tells them.

First Let’s Acknowledge Her Humanity

Before I dive into the meat of this post, let’s acknowledge we’re talking about teenage human beings. The teenage years are rough for everyone. We were all trying to figure out who we were and where we belonged. Trans teenagers have an added layer of “figuring it out”. Over the past few years, these girls have had to grapple with the fact that half the country is disgusted by their existence and thinks they’re predators. I mean, jeez, ouch. Don’t spew any hatred or disgust in the comments, okay?

Teens Play Sports for a Variety of Reasons

Another point about high school athletes is also important. Only a tiny percentage of them will continue to be athletes after high school. Most high school athletes play sports because they like being on a team, like having teammates, like the physical activity and skill. They aren’t trying for scholarships and a future as a pro athlete. If you’ve got kids or grandkids playing high school sports, how many of them want to be serious athletes long-term?

The point is that high school athletics is often more about giving teens a place to belong and to learn good sportsmanship and teamwork than it is about winning the championship and going to college on scholarship. Maybe schools should have some flexibility – a school that is competitive for the state championship may want a different policy than a school that is just happy that enough girls showed up to field a team.

About Puberty

Much of the concern I’ve seen about trans girls on high school teams assumes that she’s gone through testosterone-fueled puberty. Male puberty produces height, upper body strength, greater muscle mass, bigger hands and feet, and even their bones are more dense. These are real physical changes that must be accounted for in sports. This is the Michael-to-Michelle hypothetical.

But what about the Jack-to-Jill hypothetical? If a trans girl didn’t go through testosterone-fueled puberty, she isn’t going to have the height and mass of a boy who has gone through puberty. Jill has no physical advantage over cisgender girls. I’ll talk more about this later in the post.

High School Athletics Associations

Your state has an organization that creates the policies and other rules for high school sports teams. I looked up three, and my favorite one is Wisconsin.

Wisconsin – One Year of Medical Transition

Wisconsin’s governor vetoed a ban on transgender girls playing high school sports a couple months ago, in April 2024. That left in place Wisconsin’s policy of letting the individual schools handle the issue within the rules created by the Wisconsin Interscholastic Athletic Association (it’s a pdf and I can’t get a link to work, so if you want to look it up yourself, search for WIAA Transgender Participation Policy.) 

The Policy: “seeks to balance the important goals of: 1) equity (since providing equal opportunities in all aspects of school programming is a core value in education), 2) physical safety (since biological males or androgen-­‐supplemented biological females are typically stronger and faster than biological females) and 3) competitive equity (since the ideal of a “level playing field” is an inherent expectation at all levels of sport competition).” 

That’s a good statement of the issues they’re trying to balance.

Transgender girls may apply to compete on a girls team in Wisconsin by demonstrating that they are genuinely and consistently transgender, and being on testosterone suppressants for a calendar year: “An MTF (male-to-female transgender) student must have one calendar year of medically documented testosterone suppression therapy to be eligible to participate on a female team, consistent with WIAA policy. Note that a MTF student who has NOT started testosterone suppression therapy may participate on male teams if desired by the student, as there would be no concern about safety or competitive equity without biological interventions having been implemented.”

There it is: one year of hormone therapy before you can try out for the girls’ high school sports team in Wisconsin. Hormones determine whether you look male or female, even more than your chromosomes. I read Paula Stone Williams’ memoir about transitioning as an adult. When she started taking estrogen, her body changed. Fat deposits migrated from her chest and waist to her hips and thighs. She lost some upper body muscle mass. She grew breasts. Testosterone and estrogen are important in creating differences between male and female muscle mass. 

In Wisconsin, Jill would be able to try out for the girls sports team. Michelle … well, the timing of puberty and that one-year on hormone therapy will do a lot to keep Michelle off the girls team. It’s a calendar year requirement, and high schools don’t generally let people join a team partway through a year. That would make it very difficult for a transgender girl to wait until she’s gone through testosterone-fueled puberty and then play on a girls sports team. In the hypothetical, Michael was starting his senior year when he transitioned. In Wisconsin, he wouldn’t be eligible to be on a girls sports team because he would graduate before he finished the year of medical transition.

The one-year-medically-transitioning requirement, combined with the timing of puberty, and how long puberty takes, greatly reduces the concern about man-size people on the high school girls sports team. My son just finished his sophomore year — he grew five inches and is now six feet tall. He’s not trans, but if he went on gender-affirming care through his junior year, he would be able to try out for a girls’ sports team his senior year. He would have the height, but he isn’t through puberty. He’s built like a pencil and has no upper body strength. I had to open a jar for him last week. It will be another couple years before he fills out through the chest and shoulders. Interrupting his puberty in his junior year would stop that testosterone-fueled growth in his upper body. Individuals vary, but boys don’t usually finish puberty in high school, and if they’ve got to spend a year transitioning medically, there just wouldn’t be that many situations in which a post-puberty boy would have time to transition and still have a year or more to play on a girls sports team.

California – No Limits on Transgender Participation

In California, the policy about transgender participation on high school sports teams is wide open. California’s policy is, “Participation in interscholastic athletics is a valuable part of the educational experience for all students. All students should have the opportunity to participate in CIF activities [high school sports] in a manner that is consistent with their gender identity, irrespective of the gender listed on a student’s records.” California Interscholastic Federation Bylaws, Article 30, 300.D.

There’s been some public backlash to this. We’ll see if any changes are made.

Utah – No Transgender Participation At All

Before the law changed in 2022, the Utah High School Activities Association, which regulates interscholastic sports and activities in the state, said that a transgender girl “must complete at least one calendar year of medically prescribed hormone treatment under a physicians care for the purpose of gender transition before competing on a girls team.” [source] (After the Utah legislature passed a law, the Handbook changed and the previous Handbook isn’t available online. The 2023-2024 Handbook is at this link.)

I’ll repeat: before legislation banned them from sport entirely, transgender high school girls in Utah had to take a full calendar year of hormone treatment before they could play on the girls team in high school. In the fears and concerns I’ve seen expressed about transgender athletes, it seems to me that most conservatives ignore this requirement and assume that a transgender girl can get on a high school sports team the same day she announces she’s transgender. Perhaps that’s true in California, but it was never true in Utah.

Utah banned transgender athletes from high school teams in 2022. The legislature had to override the Republican governor’s veto in order to do it. Utah Republican Governor Spencer Cox explained his thinking:

“The veto override vote came just days after Republican Gov. Spencer Cox penned a heartfelt letter to legislators in which he said he’d been moved by data showing that including transgender youth in sports could reduce suicide rates within the group.

“I don’t understand what they are going through or why they feel the way they do. But I want them to live. And all the research shows that even a little acceptance and connection can reduce suicidality significantly,” Cox wrote.

He also cited statistics showing that while 75,000 kids played high school sports in Utah, only four were transgender, with just one involved in girls’ sports.

“Four kids and only one of them playing girls sports. That’s what all of this is about. Four kids who aren’t dominating or winning trophies or taking scholarships. Four kids who are just trying to find some friends and feel like they are a part of something. Four kids trying to get through each day,” he wrote. “Rarely has so much fear and anger been directed at so few.”

You can probably guess what I think of Utah’s trans athlete ban. There is no reason for a statewide law aimed at ONE person. 

My opinion is that policies about transgender athletes should be handled by the state high school athletics association of each state. Policies can be changed and updated and adapted more easily than laws can be passed and/or repealed. Lawmakers stay out.

Athletic Ability in Transgender Individuals

I went looking for credible, non-political studies about athletic ability in transgender individuals before and after they transitioned and found some sources. I’m not a biologist or a medical professional, but the studies linked in the next paragraph looked credible to me, and not obviously biased one way or the other.

Studies of athletic ability in transgender individuals are scarce and have very small sample sizes (understandably, since transgender individuals make up about 1% of the population and only a fraction of that 1% will be interested in sports). The studies focus on adults in elite athletics, such as Olympic athletes. There are differences per sport – some sports rely more on endurance, some on strength, some on speed. We’d expect different observations in swimming as compared to running track as compared to basketball, for example. Again, these studies focus on professional adult athletes [if you only read one of these articles, this last one is the best].

“The World Athletics, the international governing body for track and field, announced new rules in March 2024 prohibiting ‘male-to-female transgender athletes who have been through male puberty’ from female world rankings competitions.” [article] Note that the World Athletics is an organization for adults who compete at the highest levels. They’ve drawn the line at male puberty.

Athletic ability in transgender teenagers hasn’t been studied extensively. It can’t be studied. Puberty would change the results too much. You can’t do a “before and after” transitioning study focused on athletic ability in kids going through puberty. Instead, size is generally presumed to be an indicator of athletic ability.

I found a court case in West Virginia that is considering this question: “Do prepubescent people whose sex is assigned as male at birth enjoy a meaningful competitive athletic advantage over cisgender girls?” This case posed the unique question of stretching transgender bans to the lowest levels of youth sports (eighth grade), with the trans girl asserting that she has no unfair advantage because she hasn’t gone through puberty and doesn’t have the physiological traits that give boys and men athletic advantages over girls and women. [source] (Those links are paywalled, so if you want the full article, let me know and I’ll do a copy-paste.) The issue hasn’t been decided yet, but I think that’s an important issue to explore. 

Gender-Affirming Care

The worry about tall, strong, post-puberty boys playing on the girls’ sports teams can largely be solved by allowing gender-affirming care. A trans girl who starts puberty blockers at age 12 will (probably) not be six feet tall. (My cousin married the cisgender star of a women’s college basketball team and she was six foot two, so tall, cisgender athletic women are a real thing.) It’s the hormones, and not just the X and Y chromosomes, that make men (generally) bigger and women (generally) smaller. 

Let trans kids be trans. Let them take puberty blockers and live as their chosen gender. I doubt that a trans girl wants to go through male puberty anyway. Let her transition when she wants. 

Stop With the Transphobic Laws

If legislators would stop making health care decisions for individuals and let a trans girl decide with her parents and doctor to take puberty blockers and then hormone therapy, the worry about size differences and muscle mass between trans and cis athletes in high school largely goes away. As it is, states ban gender-affirming care for minors, then ban transgender girls from high school athletes because they’ve gone through male puberty. Well, if the legislatures stopped banning gender-affirming care for minors, they wouldn’t have as many transgender girls who have gone through male puberty.

If a medical treatment has risks, then the appropriate way to handle that is through education. Let the transgender child, her family, and their doctor make the decision. Lawmakers shouldn’t be making medical decisions for anyone.

What You Can Do

Run a search for your state’s high school athletics association and see what the eligibility policy for transgender athletes is. Write to your state lawmakers and urge them to pass laws that are not based on culture war fears, but on informed policies of fairness. Puberty blockers and other gender-affirming care may be the best way to include transgender girls in an important part of being a teenager, while keeping things fair for their cisgender teammates.

Questions:

  1. If a transgender girl is at roughly the same size, strength, and speed as the cisgender girls because of gender-affirming care, would you be alright with her playing on the girls team in high school?
  2. Do your cisgender girls play high school sports? Ask them what they think and let us know. Ask them if they think transitioning before or after puberty would make a difference.
  3. Do you know a young transgender athlete? Give them a hug from me and tell them to hang in there.
  4. Do you think questions about trans athletes should be handled by a state athletics association? Or do you think laws are the best way to address these issues?
