Transgender Athletes in Sports

👋 Welcome, everyone!

Our topic is Hormones and sports. We'll be discussing this statement:

Transgender women who went through male puberty but who have used hormone therapy for at least two years to reduce their testosterone levels to within the female range should be able to compete in women’s sports at all levels.

• Emery agrees with the statement.
• Wesley disagrees with the statement.

My name is Guide, and I'm here to support your discussion. If you need anything, start your message with “Hey Guide” 🤓

Hi Wesley! when would it be convenient for you to chat? I'm free tomorrow and on Monday

Hey Emery, if you want, we can do it tomorrow to get it out of the way

The reason I disagree with this is that I don't think treatment will be effective in just two years. When we are first born, we already start to go through puberty, but it doesn't show itself until we reach a certain age, or our bodies just react. So roughly 18 years of your life, you were solely producing your biological hormones. I don't think two years is enough time for the body to fully adjust to this new concept.

Why do you agree with this statement?

I agree because it says "to reduce their testosterone levels to within the female range", and I think this means there won't be any biological advantage for transgender women over other women, so it's fair. I don't know much about the biological details, but just to make sure I don't get it wrong, do you think two years are not enough to reduce T levels to within the female range?

Emery, you're raising an important distinction here. Let me help clarify what's at stake in your exchange with Wesley.

You're focusing on testosterone levels specifically — whether two years is enough time to bring them into the female range. Wesley seems to be pointing to something broader: the lasting effects of going through male puberty for roughly 18 years.

The key question is whether reducing testosterone levels alone eliminates all competitive advantages from male puberty. Male puberty creates changes beyond just circulating testosterone — things like bone density, skeletal structure, muscle fiber composition, lung capacity, and heart size. Some of these changes may be permanent or only partially reversible.

So Wesley might be arguing that even if testosterone levels drop to the female range, other advantages remain. Is that what you're getting at, Wesley? Or are you specifically disputing whether two years is enough time to lower testosterone itself?

Emery, does this distinction change how you think about fairness in competition?

Yeah, I did neglect things that couldn't be changed by hormone therapy. Is this what you mean?

Yes that is exactly my point

It’s more of both I don’t think two years is enough time due to due all the other advantages that were gained during puberty

Hey Guide help us out here where’s our stand points

Wesley, you're arguing: Two years of hormone therapy isn't enough because male puberty creates lasting physical advantages (bone structure, muscle composition, etc.) that don't disappear when testosterone drops.

Emery, you're arguing: If testosterone levels reach the female range, competition is fair — though you've acknowledged you initially overlooked permanent changes from male puberty.

The core disagreement: Does fairness require only similar testosterone levels, or does it require eliminating all physical advantages from male puberty?

Emery, now that you recognize some advantages might be permanent, does that change your view on fairness? Or do you think those advantages are acceptable/minimal?

Yes I've changed my view a little. I think we may need more than hormone therapy (or 2 years) at least in elitle's sports, but I'm not sure since I don't know what kind of permanent changes there really are.

Hey Guide, can you give more detail on the advantages?

Sure. Male puberty creates several lasting changes:

Skeletal structure: Broader shoulders, longer limbs, larger hands/feet — advantages in reach, leverage, and power generation

Bone density: Denser, stronger bones that may not fully reverse

Muscle composition: Higher proportion of fast-twitch muscle fibers (explosive power)

Cardiovascular: Larger heart and lungs — greater oxygen capacity

Height: Generally taller, which matters in many sports

Studies show hormone therapy reduces some advantages (like muscle mass and strength) but may not fully eliminate others. The degree of reversal and timeframe needed are actively debated in sports science.

Emery, given these details, where do you draw the line on fairness? What level of advantage, if any, is acceptable?

Wesley, do you think any amount of hormone therapy could make competition fair, or are some advantages simply too permanent?

I think as long as the biological gap between transgender women and other women are not binomial/totally separate, it would be acceptable. For example, if some women can have the same (or better?) height or skeletal struture as transgender women, then it seems ok to me. Also, if the biological gap doesn't matter in the specific sport, that sounds fine to me.

I will have to disagree with you I don’t think there is anyway for transgender woman’s to be equally similar biological women in the sense of there bio advantages.

I think in cases of competition I don’t think there is anyway amount of hormones you can take that will permanently take away the male advantages they developed in puberty

I do agree that after a certain amount of time about 20+ years of constant a transgender woman could possible gain more phenotype characteristics that will categorize them as female but still would have a genetic advantage compared to biological females

Hey Guide what’s our stand points

Emery: Acceptable if transgender women's advantages overlap with the natural variation among biological women — not a separate category.

Wesley: Male puberty creates permanent advantages that hormone therapy can't eliminate, even after 20+ years. Genetic advantages remain.

Key tension: Emery focuses on overlap (some biological women are tall/strong too). Wesley focuses on average advantages that persist regardless of overlap.

Wesley, here's the challenge to your view: Elite sports already have huge natural variation. Should we exclude tall women from basketball? Women with naturally high testosterone? Where's the line?

We cannot change our size and how we will develop that is just something that is based on genetics. I am a male but there are many women whom are 6 feet tall does that mean I’m more of a female and they are more male? The line is drawn once a person is taking hormones for the sole purpose to participate in the other genders sports

I don’t agree with women’s sports having decades-long records in many Olympic sports and those records getting destroyed by a rookie with less than half the experience of women that have been doing this their whole lives

With the increase of transgender women in women sports it’ll discourage biological women from participating because they don’t stand a chance. A solution I propose is create a league for transgender males and females just like the gender section in forms

That's really a great point and I agree that we have to keep the game fair for both transgender people and others, but I would still feel like it might be too absolute or unconditional👍

I think we don't really have enough data and research to say that transgender women have an inevitable biological advantage in sports. For example, one study finds that transgender women have greater handgrip strength but lower lung function and things like that. Having some permanent biological advantages is not enough to make you the winner, it can be like "carring a big skeleton with a smaller engine"

Also, like you've said, some women are 6 feet tall, so biologically speaking, transgender women may not have such a huge and unfair advantage than other women

Hey Guide, how are we doing?

You're doing well — engaging substantively with each other's points!

Wesley, Emery is challenging your core claim. She's saying:
1. Advantages might be mixed (stronger grip but weaker lungs)
2. Net effect unclear — could be a disadvantage overall

Does this change your view that transgender women will inevitably dominate? You mentioned records being "destroyed" — but is that actually happening systematically, or are there just a few high-profile cases?

I saw a news article that expressed over 900 women were stripped of their titles due to transgender women beating them. Also a lot of the times recorded from transgender women were equal to men

The advantages talked about like lung capacity and grip strength are things that can be developed by intense training and exercise. I believe that men are biological larger than women and that’s just something you can’t change you can hide it but it’s still there waiting to be activated.

Also, I guess not all transgender women iin the news haven been through "hormone therapy ... to reduce ... within female range"

The article is by Nfox14 titled UN study reveals transgender athletes have won nearly 900 medals in women’s competition

The inevitable advantage is the structure we have through genetics you can develop lung capacity through training but there’s a limit your body can take a smaller build wont be able to withstand what a bigger build can for a significant amount of time

that's an interesting theory but I'm wondering does a bigger body mean better sport performance. From my experience, in some sports

Wesley, that source is questionable. The "900 medals" claim has been debunked — it conflates all levels of competition and doesn't verify hormone therapy compliance.

Emery's making a key point: Does bigger body = better performance? In distance running, cycling, gymnastics — smaller, lighter bodies often have advantages.

Wesley, your "bigger build" theory seems sport-specific, not universal. How does that affect your blanket opposition to trans women in all women's sports?

in some sports like ping pong, bigger body makes you less flexible and thus probably perform worse. or it is not significantly related

i mean if it's just bone structures, we can have short athletes in basketball who still excel, like the shortest current NBA player is 5'8''. And some tall players don't actually play it so well

I’m mainly regarding sports that have a physical disadvantage like boxing, mma, track. Because those are individual sports.

True some players are really short and play good ball but the sad truth is if you’re too small you won’t play Steph currry almost got dropped from the league cuz he was too small but he’s the best 3 point shooter. In professional sports size does matter.

yes you're arguing in some sports size/bone structure does matter, while I'm arguing in some other sports it doesn't matter that much. So I guess we can agree to disagree here

Also, I feel like size is different from bone structures. Muscles are important for "size" but they can be affected by hormone therapy

well I think sport-specific policies are needed. And in sports where it's indeed unfair, we need some rigid evidence to support banning transgender women from the women category. If we have good evidence, I agree that they shouldn't compete in women's sport.

Yes I can agree that trans women can participate in sports such as gymnastics, shooting and equestrian

I also agree with Emery because there is a need for policies

Hey guide how are we doing?

You've found significant common ground! Both agree on:
- Sport-specific policies needed
- Trans women acceptable in some sports
- Evidence-based approach for restrictions

But here's what's unresolved: The original statement says trans women "should be able to compete in women's sports at all levels" after 2 years of hormone therapy.

Wesley, you'd exclude them from contact/power sports regardless of hormone therapy, right? So you still disagree with the statement?

Emery, you want evidence first. If evidence showed permanent advantages in most sports, would you change your "agree" position?

Yes I still disagree with the statement

Yes if there is evidence, I will agree. But since not many evidence are available right now, I am not sure about this now

My view has changed by this chat❤️

Also, our discussion has been limited to elite level sports. In recreational level sports I think it's ok because biological advantages are not so important and we're doing it for fun rather than absolute fairness
