Olympic Committee bars transgender athletes from women’s events

(www.nytimes.com)

Trans women have competed as women in the Olympics once ever and have 0 medals. By the numbers it's a non issue under previous rules (despite the incredible amount of ink spilled over it). People are talking about trans women here but the vast majority of people affected by this change are women who are not trans who have a "disorder of sexual development".
reply
The IOC policy is specifically that athletes need to test negative for the SRY gene to be eligible to compete in the female category. Imane Khelif won gold in the 2024 Summer Olympics women's boxing event, and has since admitted to having the SRY gene. So it isn't a non-issue.

https://en.wikipedia.org/wiki/Imane_Khelif#2026

reply
So it's the headline that's inaccurate. It should read "bars women with the SRY gene" rather than "transgender."
reply
It should read "bars male athletes".
reply
The page you link to doesn’t say that. “As of February 2026, Khelif had not described herself as intersex or as having a DSD.”
reply
There is a leaked medical report showing that Khelif has internal testes:

https://www.dw.com/en/algeria-condemns-baseless-imane-khelif...

The Talk page has extensive debates on whether this can be mentioned, and the current "consensus" is that it can't be.

reply
Internal testes due to 5-ARD, a disorder of sex development that causes the penis to be underdeveloped, which explains why Khelif was erroneously assigned female at birth.

The guidelines for trans female athletes for the 2024 Paris Olympics involved transitioning before the age of 12/puberty to be eligible.

There's more info at https://www.independent.co.uk/sport/olympics/paris-2024-olym...

reply
Incidentally, many countries/states are working hard to make it impossible to transition that early.
reply
At 12 you simply do not have sufficient capacity to make a good decision on the matter.
reply
Is it fair to say that they can just compete in the men's division?
reply
From a biological perspective, the women being banned here are not just men and as far as I'm aware cannot realistically compete in the men's division any more than any other woman. Practically these changes bar women athletes with certain medical differences from competing in the Olympics.

I'm not an expert so idk whether that's fair or not but that's what this decision is doing.

reply
Can you define what you mean when you use the word “women” here?

My understanding is that these are males.

reply
Like most things in biologicy, categorization is a nightmare unless you have a very specific use case in mind. In this case I'm talking about women phenotypically and socially (including self-identity) and especially athletes assigned female at birth. These women are clearly not just "males".
reply
For most of the sports there is no men so division it's open for everyone.
reply
It would not be fair, because the point of having divisions is allow women to compete in a competition that is not dominated by men.
reply
I think you're falling for Sticker Swap Fallacy. The goal is to have fair match-ups in sports. Gender and sex are two possible labels to use to assist with this, but they're imperfect enough that we probably ought to not use them as the primary differentiator.

https://www.lesswrong.com/posts/C7LcpRtrHiKJRoAEp/sticker-sh...

reply
The solution is simple: class every sport like boxing.

Pick a sports-relevant metric and split into divisions. Some sports will naturally fall into gendered divisions, while others will have varying degrees of co-ed competition among competitors of similar ability.

The way out of this is not to pick a better scissor of sex or gender, it's to pick a better scissor of ability.

reply
This "solution" can really only be proposed by someone who has not played sports. This would simply result in women being unable to compete in sports professionally, outside of a couple small niches like ultra long distance swimming and a couple sub-disciplines of gymnastics.

I do not consider that to be a good thing.

reply
It really depends on the way classes are divided. Dismissing the general concept demonstrates a fear of change rather than a legitimate openness to fair play.
reply
No it doesn't, and no it doesn't. Proposing this concept demonstrates a profound ignorance of what competition at the top level of sports actually looks like.

The concept is just bad, unless your goal is to prevent women from being able to make a living playing professional sports.

reply
The thing is, we're already using a scissor for ability, just a poor one with the exact problem you describe - it renders trans women unable to make a living playing professional sports. Throwing one group under the bus for another cannot be avoided so long as sex or gender are part of sports divisions.

Please let go of the need for this.

reply
You are clearly out of your depth. Have you ever competed in high level sports? Please don't speak on things you know nothing about. It takes a lot of gall to tell someone 'please let go of the need for this' when they are pointing this out. I will do no such thing, but I likely will give up trying to educate you.

I won't respond further unless you pick an example sport, and propose how your "scissor for ability" would work, in concrete detail. If you do this, I will be happy to explain why this would result in neither women _nor trans women_ having any chance to make a living as professional athletes.

Doesn’t Boxing use weight classes?

Really, what it is is being dominated by Testosterone. Also why we ban steroid use, and many other things along the same lines.

I would suggest that most Olympians - both female and male (whatever your definition) likely have a higher than normal amount of that hormone.

reply
This is common sense. The only reason it didn’t happen sooner was folks being bullied to do things out of false claims of “inclusion” that resulted in deep discrimination against, mostly female, athletes.

The segregation of sports was always about sex and not gender. There are simply physical differences between across sexes that makes mixed-sex competition grossly inequitable in most sports. “Gender expression” doesn’t change that and mixing up “gender” and “sex” in sports was a trainwreck that is thankfully now being undone.

This is the right decision.

reply
Many people like to focus on the purely physical attributes, but there's a clear distinction even in realms like chess.

The highest ranked female chess player is right around #55 globally, wherein the top 50 all are dominated by men.

Some of this may have to do with men having more interest/higher propensity of starting young which is where most grandmasters begin their journey, but still an interesting thing to consider nonetheless.

reply
It's largely because chess has historically been a boys-club type activity. Women were actively discouraged, if not barred, from playing on grounds of misogyny. So, even today, there's very little women taking it seriously.

Of course, we all know there's no difference in the level of intellect or strategy between men and women.

reply
> Of course, we all know there's no difference in the level of intellect or strategy between men and women.

Do we?

I thought it was commonly accepted that the average and median are the same but that men have more outliers on both sides.

reply
Males have better spatial abilities compared to females. Most probably as a evolutionary trait required for hunting.
reply
Exactly. It's impossible to have both inclusion and fair play. We have to pick one, and as a parent of daughters who compete at fairly high levels it's more important to preserve the integrity of women's sports.
reply
Is there not an option to have inclusion at grassroots level and fair play as the level of competition gets higher?
reply
In my experience competing in different things, that's typical: Local organizations are free to set their own local rules, but once you cross over into events that make you eligible for higher level competition they have to strictly abide by the national level rules. I couldn't use my results from grassroots competitions to qualify for national level events, generally.
reply
Sure, I guess that's an option for youth sports in the prepubescent age groups. As a practical matter most youth sports leagues and schools aren't going to hassle with sex screening tests for little kids.

But once puberty hits everything changes. My teenage daughter played travel club volleyball on a pretty good team, and during practice they would occasionally run drills with the boys team. Even at that age the difference in hitting power and vertical was enormous, and those differences only grow larger with age. Men and women are literally playing different games. Beyond just fairness, forcing girls to compete against biological males becomes a safety risk due to concussions from taking a ball to the head.

reply
It’s not even a level thing[0]. I think the physical advantages that come with male puberty are significant even at 14-15.

reply
So, where are the scores and scores of trans athletes dominating women's sports? If this is the sort of problem all the people crowing about it think it to be, we should have women with poorly fitting athletic gear and facial hair all over the place taking golds from ciswomen. We don't.

Like this is literally just fucking with transpeople for nothing and I am wide open for correction on this if anybody can find an actual incident of something of note happening, but until then, it's just weird reactionaries screaming into the void as far as I'm concerned, and the outcomes will be largely the same: more invasive procedures for ciswomen to endure, and excluded athletes who did nothing wrong apart from be who they are.

reply
This is a matter of principle, fair play, and safety. Whether it's a tiny number or "scores and scores" is irrelevant.

If you're looking for specific incidents then start with this site. I can't vouch for it being completely accurate but you can use it as a starting point for further research to educate yourself about the issue.

If you segregate by sex alone then trans men get a big advantage.
reply
The rulings do not segregate by sex alone. Someone who was AFAB and does not have an SRY gene would was taking HRT would not qualify for the female division due to the HRT.

A trans man who was not taking HRT could compete, though.

The key distinction is that gender identity is not what's being tested.

Because they're taking testosterone?

Wouldn't they be barred based on using banned substances?

They're not all taking banned substances. Case in point, Hergie Bacyadan and Elis Lundholm competed in the last Summer and Winter Olympics respectively.

Depends on the time of the transition. So those who transitioned before puberty are disadvantaged

I thought exactly the same thing until I had a politically agnostic fencing judge sit down and explain over the course of an hour and a half all of the steps national and international regulating organizations for that sport had taken to avoid issues with unfair competition. Whether similar field-leveling safeguards could be baked into the rules for other sports is left as an exercise, but this particular instance suggests there's more nuance here than your comment suggests.

Walk me through how you think this is going to be enforced? Athletes will need to start dropping their pants? Disgusting invasion of privacy.

The article addresses that. Given all the testing already, this is a trivial addition:

“Under the new policy eligibility will be determined by a one-time gene test, according to the I.O.C. The test, which is already being used in track and field, requires screening via saliva, a cheek swab or a blood sample.“

reply
You think Olympic athletes have any expectation of privacy around drug testing already? They have to register their every move and piss while being visible on demand.
reply
Well the article says a cheek swab or blood test.

You think the only way to medically test for male vs female is to visually id genitals?
reply
The article already covered it: It's minimally invasive (cheek swab) testing typically for the SRY gene - https://en.wikipedia.org/wiki/Sex-determining_region_Y_prote...

This is less invasive than all of the other doping tests that athletes already go through, which require blood draws.

reply
Doesn’t really work though - and given athletes are on the edge of performance there’s probably more people that fall in between than you might expect

From the Wikipedia article:

While the presence or absence of SRY has generally determined whether or not testis development occurs, it has been suggested that there are other factors that affect the functionality of SRY.[25] Therefore, there are individuals who have the SRY gene, but still develop as females, either because the gene itself is defective or mutated, or because one of the contributing factors is defective.[26] This can happen in individuals exhibiting a XY, XXY, or XX SRY-positive[27] karyotype[better source needed] Additionally, other sex determining systems that rely on SRY beyond XY are the processes that come after SRY is present or absent in the development of an embryo. In a normal system, if SRY is present for XY, SRY will activate the medulla to develop gonads into testes. Testosterone will then be produced and initiate the development of other male sexual characteristics. Comparably, if SRY is not present for XX, there will be a lack of the SRY based on no Y chromosome. The lack of SRY will allow the cortex of embryonic gonads to develop into ovaries, which will then produce estrogen, and lead to the development of other female sexual characteristics.[28]

reply
The Yahoo article linked says that exceptions will be made for people with conditions like that:

“Athletes diagnosed with Complete Androgen Insensitivity Syndrome (CAIS) ‘or other rare differences/disorders in sex development (DSDs), who do not benefit from the anabolic and/or performance-enhancing effects of testosterone’ may still be allowed to participate in the women’s category.”

The IOC included exceptions for certain DSDs.

Please read the linked articles first before jumping to Wikipedia to try to counter them. The decision is more nuanced than you assume

reply
In a word: so? Intersex people exist, you have to draw the line somewhere, the presence of SRY seems as good as any.
reply
The test is used for initial screening only.

Presence of SRY in an athlete registered as female means further tests must be undertaken, with permission of the athlete, to determine eligibility.

Absence of SRY means the screening is passed and the athlete is eligible to compete.

reply
Transition changes biology. We don't yet have the technology to fully reverse the effects of male puberty, so there can be reasonable debate about trans women who transitioned after puberty, but early transitioners have no meaningful advantage. Their bodies, in an athletic context, are female.

This is also true for many cisgender intersex women with XY chromosomes. Someone with androgen insensitivity can have XY chromosomes, yet be capable of giving birth. Drawing the line at having a Y chromosome makes no sense.

reply
There are athletic sex differences even amongst prepubescent children, mostly caused by the testosterone surge in utero.

See https://womenssportspolicy.org/pre-puberty-male-female-child....

reply
> Their bodies, in an athletic context, are female.

I'm sorry, but this is not true. "Puberty blockers" do not complete suppress the effects of male genetics. They only attempt to block certain hormonal effects.

It is not possible to completely block the effects of having male genes by simple hormone modulation.

> Someone with androgen insensitivity can have XY chromosomes, yet be capable of giving birth

We do not determine eligibility for sports classes based on ability to give birth for good reason. It's not a proxy for the genetic athletic differences being addressed by these classes.

Individuals with androgen insensitivity typically cannot give birth. This an extremely rare possibility, not a typical feature of the condition.

Why not ignore gender labels and go by chromosomal configuration? There could be XY and XX [1] olympics. And then there should be X, XYY, XXX, XXXY, XXYY, and all the other possibilities [2].

All biological categories are fuzzy around the edges. Those fuzzy edges do not invalidate the category. The existence of small #'s of people with actual physical intersex conditions (not "I feel like <x>") in no way conflicts with humans being sexually dimorphic.

I agree with you in general, but I think it would be fair to let XY individuals with CAIS compete on the female side - their bodies do not respond to testosterone.
reply
This also bans cis women with genetic anomalies. Until men with genetic anomalies are equally banned from sports (for example, being an outlier in height for basketball), this is nothing more than a misogynist attempt to make women’s sport as unimpressive and average as possible. Rules set by mostly old men of course.

Remember, sport is and has always been about statistical outliers competing. Fairness has never been, and will never be, a genuine consideration.

It’s also mighty interesting how it’s always the male division that’s open, until you happen to have a sport where women are beating men at it, and then suddenly it’s the women’s division that’s the open one! (See shooting.)

Stuff like this is why professional sports is widely seen as a cheater’s club where everyone tries to cheat as hard as possible just shy of getting caught, then acts completely innocent and indignant when someone else just barely crosses the line into getting caught.

> Until men with genetic anomalies are equally banned from sports (for example, being an outlier in height for basketball)

We don't have height categories, we have categories based on sex. We have categories based on sex because there are physical difference caused by difference in sex that lead to advantages in sports competitions. As such, people who have physical advantages over others based on their difference in sex (e.g. going through male puberty vs. female puberty) shouldn't be able to compete in the category created to protect participants from precisely those differences.

reply
I would argue that it's the formerly presumed binary nature of sex/gender that made it a logical split for all sports. While marital arts and weightlifting tend to seperate by weight as well, that is because those particular events are particularly biased toward muscle mass and height/reach by proxy. Most sports are less clearly advantaged by size (soccer, for example). You just can't practically divide entire team sports by gradations of height, because there aren't enough players in a school for more than a few squads.

If you wanted to divide by height or weight in a binary fashion to reduce the number of teams, then obviously you'll just have some sports where everyone in the under-6' team is 5'11.5, which seems not optimal and unfair.

I wish there was a good solution.

reply
> We don't have height categories, we have categories based on sex.

I mean, we do have weight categories in combat sports, right? I don't see why we couldn't come up with similarly neutral categories if we think it's good to segment people out by physical advantages. The parent comment is making a good point, though: it feels like some people care a lot about physical advantages that map onto gender stuff they care about, and not a lot about weird genetic anomalies that provide physical advantages that aren't gendered.

reply
We could do that! I'm just trying to say that given categories based on (biological) sex, we should find some criterion based on biological sex to sort people into said categories, which the OC decision seems to do (at least better than the alternatives I have encountered). I don't have a problem at all with finding different ways of defining categories for competitions.

Re: anomalies - I think this is just unavoidable in any sort of category system, and I don't have a good solution for it except to consider frequency and severity.

reply
Well I think it bans women that thought/think that they are cis but actually aren't, which is a bit of a different story. A fairly tragic one. Intersex/trans/anything else people just don't really have a clean fit into a lot of places, which is unfortunate.

> this is nothing more than a misogynist attempt to make women’s sport as unimpressive and average as possible. Rules set by mostly old men of course.

Well, not really. 56%[1] of young women think that trans women should not be allowed in women's sports.

> It’s also mighty interesting how it’s always the male division that’s open, until you happen to have a sport where women are beating men at it, and then suddenly it’s the women’s division that’s the open one! (See shooting.)

IMO the "better" division should be open. If we are going to do two classes, and we find that one class has some sort of physical advantage inherently, then that class should be the "open" one.

> Stuff like this is why professional sports is widely seen as a cheater’s club where everyone tries to cheat as hard as possible just shy of getting caught, then acts completely innocent and indignant when someone else just barely crosses the line into getting caught.

A lot of people (the majority?) don't understand the extent of PEDs usage in sports. When everyone cheats nobody does. I've heard the argument before for going an "anything goes" division from friends for some sports, but then people are just going to start dying regularly from side effects like in body building.

Hypothetically you could have three divisions: open, men, and women. In many contexts it's more practical to have two, where one is open. In those cases, if the sex that didn't win more was also the open division, then people would complain because both divisions would be dominated by players of one sex.

what always strikes me as weird is how often the conversation is framed around "men competing in women's sports" when trans women cant really be said to be biologically male anymore. Taking Estrogen and blocking testosterone has a huge effect on how fast/strong/athletic someone is.

Testosterone and estrogen are not magic substances that eliminate bone density, preponderance of type II muscle fibres, favourable tendon insertions and all of the other athletic advantages conferred upon males in the womb. I have experience with women who take steroids for strength sports and I am not exaggerating when I say they could be out-competed by 17 year old male high school students with proper coaching.

That isn't the key point. Taking hormone therapy as an adult doesn't erase the huge athletic advantage conferred by going through male puberty.

There is no way a man would ever compete in women's sports.

Let's imagine a con-man wanted to compete in women's sports. He would have to decide this early in life. Most trans people realize before they are 10. He would then have to spend the rest of his life pretending to be trans to not get his medal revoked.

Trans women are women. They don't have to pretend to be women. However, some trans women have to hide their identity and present as men, for their safety. Presenting as a gender you're not is incredibly taxing. There are high rates of depression and increased risk of suicide for people who have to hide their gender.

Besides the incredible psychological toll, our imaginary con-man would face bullying, harassment, physical assault, sexual violence, employment discrimination, housing discrimination, exclusion from healthcare, and increased risks of poverty and homelessness, which in turn correspond to greater risks of fatal violence.

The rights and legal status of transgender people vary by country. Our imaginary con-man might have restricted access to education, to sports, to bathrooms, and to marriage and military positions. As well as much, much worse.

On top of all that, our imaginary con-man would still have to train to be an Olympic athlete. Most men are not as fast or strong as the world's fastest and strongest women. Sex differences in athletic performance also depend on more than just biological differences. Living as a woman means only having access to the resources available to female athletes.

No man would go through all that for a women's medal.

reply
Has anyone measured trans athletes performance?

I see this topic come up repeatedly in different guises, protect women from the evil trans-agenda. But I haven't seen where this is actually a problem.

Do trans-athletes regularly out perform "born as" (not sure the best way to phrase it) athletes?

reply
Many studies show with in ~10% female ranges of ability , but, having more fast twitch muscle fiber and bone mass from male puberty if they went through it. Bone mass does eventually drop to female levels but over decades not years so athletes would likely be out of athletic prime before that happens. Studies showing more dramatic results that stand out in my memory that lean toward transwomen outperforming transwomen are studies done on military veterans comparing to general population metrics of muscle mass for athletic activity levels also done with a very low population count I believe they only looked at under 300 trans women. Regardless we need more research, but there are a comically small amount of trans athletes seeking professional level sports, like I think <20 for all college level for instance.

Anecdotally, I found as a deskjob, pilates and casual weight lifting trans woman, I lost dramatic amount of strength and muscle mass. 20 pounds now feels like 50 pounds did for myself pre-transition. I usually participate with women and the instructor/personal helps with modifications usually aimed at women just getting into fitness. Running joke amongst friends is how easily I am outperformed by my female friends at the gym/pilates/etc. However, that's since my body is low testosterone even for females, its checked twice a year because of it, normally It's once a year for most trans people. Other friends retained a lot of their strength, but are mechanics, so its really situational in my opinion, and its a super hard and interesting topic of research because of it

Regularly. It's the competing women who are complaining, though. They feel it is unfair to compete with men.

The findings I posted where from the linked article, to the nytimes. The findings were exactly as I posted them; in brief, athletes born with male markers retain their physical advantages.

reply
There’s probably a reason the analysis has not been made public.

It’s not evidence until published because it can’t be disputed.

reply
I can't believe you need a study to show that a man turned woman has an advantage. It's clear men vs women have an advantage in almost every discipline... So are you simply unsure if the transition process doesn't totally ruin them and degrade their performance to that of a woman?
reply
This is more about logic.

For this article to be relevant a spot for the Olympics of either gender has been taken by a trans athlete.

Which by conclusion means that a trans person outperformed the other gender.

Taking part in the Olympics is a difficult endeavor, for which you must qualify first.

reply
That's a misleading way to talk about "outperforming". When the US brings over 200 people to the olympics, then if cis and trans athletes have exactly the same performance and without other bias you'd expect to see 1-2 trans US olympians every year just by chance. And you'd expect them to have the same medal rates as anyone else from the US. When someone asks if there's evidence of trans athletes outperforming cis athletes, that's not what they're asking for.

Citation? Data? Let's take Paris 2024 track and field 800 m as an example, I won't do all the googling for you. In men's heats, the slowest clocked time was a hair under 1:55. In women's finals (consequently the fastest time of the competition), the winner clocked in at a bit under 1m57, whereas the men's final was won with 1:41 and change. You may look up other competitions by yourself. The reason for the lack of "citation", or "data" as you call it, is because men typically are not allowed to enter women's competitions, for that - rooted-in-reality reason I just demonstrated.
reply
Well, trans women given current regulations that allowed competition with cis women, would have had to be on hormone replacement therapy for 3-5 years depending on the sport. So the data and context does matter, because the intuitive conclusion you came to isn't touching a dataset to find the rooted-in-reality conclusion. The question is 'is a male with a female hormone balance for over X period time with in a fair difference in biological function to females.'. Which is a complex question, since so many things are at play. How much does fast twitch muscle fiber is retained? How much does that even matter for the sport in question?(ballet vs sprinting) Did they go through male puberty? Where are they working out to retain their muscle mass through their 3-5 year transition period and not losing any of their originally gained muscle? What would it look like if they intentionally lost the muscle mass and then retrained it back?

I find those to be fascinating questions, the later we have little research on, currently, and it could enlighten so much more of exercise science especially for cis athletes as well.

Hormone expression. Muscle mass. Reaction time. Weight.

A YEAR of hormone therapy. Meeting a required measured threshold of testosterone.

And that's not even the controversial stuff. A man and a trans-woman are different. hell, one has (generalizing here) boobs: come on... don't be dense/obtuse! Have you tried running fast suddenly having boobs when you did not before?!?! ...one is way easier.

reply
The problem is that someone who's transitioned is no longer a man. After undergoing surgery and hormone treatment for a long period of time, a trans athlete falls somewhere between men and women in terms of capability. They'd have no more success competing against men than naturally born women would, yet they still have advantages when competing against naturally born women.

Unfortunately, while the most equitable solution might be to create a separate category unique to trans individuals, there aren't enough trans athletes to make it feasible (yet?). It's rather sad that transitioning means a person can no longer compete in sports, but I'm not sure there's a better alternative.

reply
You still have your larger bone structure. Larger musculature structure and different muscle insertions. different ligament structure. different skin structure. different grip strength. Broader shoulders, narrower pelvis, different angled limbs. all of that isn't going away even if it atrophies. And you aren't going to let it atrophy because you are an athlete in training managing your dietary macros. Maybe recovery isn't as efficient lacking so much excess testosterone but you still have some.

From the article:

> Late last year Dr. Jane Thornton, the I.O.C.’s medical and scientific director and a Canadian former Olympic rower, presented the initial findings of a review of athletes who are transgender or have differences of sexual development, known as DSD, and are competing in women’s sports. That analysis, which has not been made public, stated athletes born with male sexual markers retained physical advantages, including among those that had received treatment to reduce testosterone.

Let's be a little science-focused, okay?

reply
That very quoted section indicates the analysis has not been made public. IMO that's very fishy and makes me question the authenticity of the source. What is Dr. Thornton hiding, exactly? Why conceal the review, methodology and data? Even if preliminary it should be released.

So much for science.

I would be interested to see that analysis, and it's unfortunate that it is not publicly available in some fashion. I'm mainly curious about the number of DSD-expressing vs transgender athletes they reviewed. Trans athletes in the Olympics or even competing at an Olympic level are vanishingly rare.

"born as" (not sure the best way to phrase it)

The usual term is "cisgender", or "cis" for short.

"Cis" and "Trans" both come from Latin; the former means "the same side of" and the latter means "the other side of". If you are happy to be on the same side of the gender binary as what you were assigned when you were born then you are "cisgender"; if you are unhappy with that state of affairs (regardless of how much work you have put into changing it) then you are "transgender".

reply
Adding to this: If you do not want to reference the current gender, you can also use "Assigned Female at Birth" (AFAB), or "Assigned Male at Birth" (AMAB).

This is useful when clarifying terms, when you do not know the persons identity, or when discussing groups based on the factory default settings.

Now you say it like that, I did know that. Thank you.

Certainly some of the high profile cases have been fairly absurd. A mid-tier male athletic transitions, and then blows the female record out of the water and gets gold.

reply
> Do trans-athletes regularly out perform "born as" (not sure the best way to phrase it) athletes?

The closest controlled study we have on this topic is not in athletes but in U.S. military servicemembers and their standard fitness test: https://pubmed.ncbi.nlm.nih.gov/36271916/

This isn't a good study for professional athletes training for competition because the fitness test is not analogous to professional competition. They only need to pass with a reasonable score but most are not competing for the top position like in the Olympics

The study found that

> transgender females' performance showed statistically significantly better performance than cisgender females until 2 years of GAHT in run times and 4 years in sit-up scores and remained superior in push-ups at the study's 4-year endpoint.

So of the 3 simple activities they tested their performance remained higher in one test (run times) until 2 years, another test (sit-ups) until 4 years, and remained higher at the end of the limited 4-year study period in the last test (push-ups).

This study was widely circulated as "proof" that hormone therapy erases sex-based gains after only 2 years, but that's not even an accurate read of the study. It's also not measuring athletes who are training or trying to compete.

Depending on the sport, hormone therapy cannot be expected to compensate for sex some important sex differences like physical structure. Male anatomy is simply different in ways that provide different types of leverage or angles (like Q Angle, which runners will talk about, or reach, which is important to boxers)

This is a very taboo topic to discuss and honestly I'm a little nervous to even comment about it here pseudonymously. The popular culture discussion of the topic is very different than the sports science discussion of the topic, where sex differences have long been accepted to be innate and irreversible, regardless of hormone therapy.

reply
There is no standard 'trans athlete'. Every case is different.

Transition is a process. Potentially a long one without a clear point of completion. Which makes things more complicated.

No idea on the hard data. but... We classify competitions for a reason. The competition is more interesting when the competitors are categorized into similar ability.

You can't bring your formula1 to a touring car race just because you feel like it is a touring car.

Personally I think at the top level there should be an unlimited class. within the rules of the sport anyone can enter, then at various lower prestige levels participation is limited according to some parameter.

reply
One interesting example of this is the UTR system for tennis. It is agnostic in gender as wells as age, and tournaments can be held purely based on the UTR range

bad comparison - here is one better, not a perfect one...

You can't enter a car into a boating competition. The question here is: if you take basic precautions to make it the same class of boat - a modified car turned into a boat should be a valid entry - provided the engine speed roughly matches.

People worry about cars on water here, not knowing that doesn't exist by definition: any car in water has been modified from a car to be a boat. you may recognize that it was once a car - but that's vestigial shell stuff. the inter-workings are a propeller - not a wheel.

reply
I see your argument and has some merit but isn't persuasive enough. I would posit that its a bit too loose and that it breaks down on biological people have many more complicated systems that aren't simply re-categorized similar to your car and boat comparison.

For better or worse nor is our medical science sophisticated enough to swap out the systems to be true comparables (and I don't mean to offend anyone).

reply
> No idea on the hard data

Great thanks!

reply
> Do trans-athletes regularly out perform "born as" (not sure the best way to phrase it) athletes?

No, both because there are very few trans athletes in competition, and because trans athletes (except trans women who have not started or are less than a year into hormone therapy) have net athletic disadvantages, when considering all factors relevant to performance in almost any real sport, compared to cisgender people of the same gender identity.

I mean, if you had a sport that isolated grip strength alone, trans women would have an advantage over cis women, but aside from rather contrived cases like that, they don't.

There's a reason the poster woman for the political movement around this in the US is a cisgender woman whose story of "unfair competition" is tying with a trans woman for fifth place behind four other cisgender women (and having to hold a sixth place trophy in photos, since there were not duplicates on hand for the same rank) in an intercollegiate swimming competition.

I always thought the more elegant approach to all of this was to add a mixed sex league. Keep the traditions, add a novel new one, and let people consent to who they want to compete against and watch

Correct and it’s the same in many sports. Theres generally not “men’s golf” and “women’s golf” there’s just “golf” and “women’s golf.”

Women are not excluded from golf tournaments, but the requirements to compete (primarily how far one hits the ball) are vastly different. Thats why both play the same golf course, just from different tee boxes.

Right but why not a specific carve out instead of a loop hole? If it's called "men's" the intention is clear.

I think they're trying to say that if there was a mixed league it would always end up being 100% men at the highest level. Like, mixed league basketball would almost certainly be just men at the highest level because of how the sport works.
reply
In the sports I competed in, the men's class was an open class. Anyone could compete in it. The women's classes were the only restricted classes.

There are several sports where female physiology (skeletal structure, etc) has inherent advantages over male physiology where this may not be true, though.

Caster Semenya is XY with a DSD (5-ARD), and absolutely should not compete with females. The same goes for Imane Khelif who was the same DSD.

none

However there are women who have given birth who will fail that SRY test

Sports already exclude most people as they're not performant enough. So I don't see a problem with excluding biological males from female sports.

But, we should compare actual body parts that are relevant, for example I'm male but I'd not belong in male sports as my body is more feminine..

Still, it's not who you think you are that should decide, it's the body type so the competition can be more interesting as that is the point of sports anyway..

Not only trans athletes, but any biologically born women the IOC thinks are insufficiently feminine.

It’s an unfair advantage apparently. You know, like being born tall for basketball players. Curious how no other biological advantages are being policed.

That doesn’t seem to be the case, given the first paragraph of the article:

> The International Olympic Committee has barred transgender athletes from competing in the women’s category of the Olympics and said that all participants in those events must undergo genetic testing.

Genetic testing doesn’t leave a lot of room for accidentally or intentionally targeting women for being “insufficiently feminine.”

reply
This might be true if the Olympics were exclusively classifying the 23rd chromosomes, and nothing but.

Leave aside the fact that very few of us here have actually tested our 23rd chromosome. Historically, the Olympics have not been (and are not) strictly chromosomal. The 2023 testosterone suppression decision requirements has exclusively impacted cis women, for one example.

Humans are biologically dimorphic in the same way winters are usually cold and summers are usually hot.

No, that is not a good analogy at all. It's so poor an analogy that it's challenging to interpret this comment generously. I think you might be arguing facetiously to make a different rhetoric point than the literal content of your post, bot I will respond to your text literally.

Humans have a wide variety of biological variation in metrics we think of as linked to "biological sex" and those metrics are accessibly mutable. Even within the Olympics, the natural variation of these metrics within cis women is a famous topic of debate (Imane Khelif, Caster Semenya, etc.)

Bipedalism is something which varies very rarely and is especially not accessibly mutable.

That’s a very fun way to think about it, but it’s far more effective in a semantic debate than a serious one. I also don’t for a minute believe that the goal here is some broader reform of how the world talks about statistical distributions.

I’d rather not have discussions in bad faith.

reply
It was intended in good faith, to make the point that rarity alone is not a good metric for salience. In my experience, most trans people have no problem with the statement "humans are sexually dimorphic" in a biology context. They (and I) have issue with it when its used in a debate to say "Humans are sexually dimorphic (and therefore trans and intersex people are irrelevant/shouldn't be accommodated/don't exist)". In the context of sports, it is definitely relevant that there are many edge cases and substantial overlap in the distribution of phenotypes between AFAB and AMAB people.

Coming back around to the olympics: I agree that humans are bipedal, but that has no bearing on the fact that the Olympic committee should take great care to create rules and categories for paralympic athletes. I think there's a lot of room for reasonable people to disagree without dismissing the complexity that comes from organizing across 8 billion people.

Before you hold genetic testing down to this standard of perfection (catching a single event of something so notable it merited its own article in JCEM), it would do well to compare it to the alternatives from which you are moving, and whether those alternatives met this standard of perfection.

Otherwise it might turn out you are proposing a standard that no system that bifurcates men and women can achieve, and on the basis of that, rejecting genetic testing.

reply
Is the "genetic testing" for the presence of a Y chromosome or the presence of the SRY gene? And what about people with AIS?

If it's just karyotype, are men with XX male syndrome (SRY gene without an Y chromosome) then allowed to participate in women's sports?

reply
It's very confusing topic. I rendered this visual map to show how SRY gene is the 'trigger' for development, not just having the Y chromosome. It helps see the signaling steps where things like AIS or XX syndrome happen: https://vectree.io/c/y-chromosome-genomic-signaling
reply
The question comes down if the presence of the SRY gene impact athletic ability. From my reading, it seems very much like an ongoing research topic.

I recall a study looking at genetics in general and how much of professional sport abilities that can be attributed to it, and the number were fairly high for most sports, especially those involving strength and endurance. Genetic disorders like AIS could however also be a hindrance.

I do recall that in some endurance sports, certain genetic disorders involving oxygen delivery were much more common in top elites than in the average population, meaning that people without that disorder is at severe disadvantage compared to general population. It is an ongoing discussion if people with those kind of disorders should be allowed to compete in for example long distance skiing, as the disorder becomes natural doping and would be cheating if a person without the disorder was competing with that kind of blood in their system.

Genetic testing, outside of the culture war about what defines a man or a woman, really comes down to what is fair competition. Personally I can't really say. Does knowing that maybe half of the top skiers has a rare blood disorder make it less fun for people?

Climbers come in many different shapes and sizes. Some climbers look like string beans, others look like they grew up lifting cows.

And BTW, there are women (Janja Garnbret, and Akiyo Noguchi before her) who dominate the women’s competition for years, to the degree that everyone else is almost playing for second place. It’s routinely speculated that Janja could regularly reach the men’s semi-finals.

reply
> It's clear how insane this culture war against trans people is when you consider this only applies to trans women and not trans men?

In most sports, the "mens" division is actually an open division that accepts all participants regardless of sex. Women just don't compete in it because they have no shot at getting a decent placement. The fact that males and females can't fairly compete with each other is the raison d'être of the women's league. This, and not culture war propaganda reasons is why only the most deranged bigots have an issue with trans men competing in "mens" sports.

Trans men don't compete because women are essentially non competitive against men in top level athletics. Which is why trans women are controversial in women's sports. Every year there are hundreds of males highschoolers who outcompete females Olympic gold medalists. By allowing men to compete in women's sports you prioritize the notions of identity of what's usually a single individual over an entire class. It's plainly sexist.

As for intersex individuals, put them in their own competitive class.

Trans women are such a minority in women's sports it's really a non-issue that's been blown out of proportion. There was one trans woman who competed in the 2020 Olympics and she didn't even place. Riley Gaines has made a big deal in MAGA world about tying for 5th with a trans woman in a swimming competition. That means 4 cis women placed ahead of her, and if Lia Thomas hadn't competed, she still would've been in 5th. Hormone replacement therapy for trans women often results in muscle and strength loss, so the idea that trans women have some uniquely superhuman strength because they used to be men is just untrue.

> Trans women are such a minority in women's sports it's really a non-issue that's been blown out of proportion.

Indeed, but this is only a good argument for barring trans women from competing against females. You see, if trans athletes are so rare, only a very small number of people would be adversely affected by such a restriction, they can live with it.

On the other hand, the ban would calm down a large number of female athletes who are seriously disturbed by the mere possibility of competing against men, especially in contact sports, but not only.

Women are women, not only physically but also emotionally and mentally. Setting out on a crusade to change the thinking of millions of women is seriously dumb when a simple restriction, affecting 3 people total, can avoid it.

Now, think about making such a dumb idea a cornerstone of some party's political messaging... that can happen only if said party wants the other side to win.

HRT still leaves you with longer limbs and larger lungs which give a serious competitive edge. The numbers of trans individuals in sports doesn't matter, it's wrong on principle. Why segregate by sex at all? Let's get rid of it, you won't see any women, or any trans women, for that matter, anywhere on any serious athletic playing field. It'll all just be men.

What's the point of allowing trans women in women's sports anyway, especially at a top level? To affirm their identity? That throws an entire class of people, women, under the bus. Top performing males have an indisputable competitive advantage against top performing females in athletics.

I was wondering about trans men and there is actually quite a bit amount of regulations for it, as taking testosterone is generally considered to be doping. Trans men are only allowed to compete if they are under heavy supervision by a medical professional and they follow a very strict set of rules dictating how, when and what kind of treatment they do. Too high amount of testosterone or too uneven levels of testosterone will disqualify a trans man from competing.
reply
Trans men have no advantage against cis men.
reply
I'm not sure that is the case in all sports. For example in golf, the top women golfers on LPGA tour in distance are only about as long as the shortest men on PGA tour off the tee, about 290 yards average. However, the women are generally vastly more accurate than the men in pretty much every distance tee to green. Their swing is just a different style of swing afforded by female anatomy. It is more hip driven, "textbook," in fact they have higher hip speed than men who rely more on hand speed.

Now imagine a pro golfer who was born female with those anatomical advantages for golf flexibility, and is now taking testosterone for power, ostensibly to identify as male. Not only do they have the anatomy advantage, they now have the power. They would probably dominate pro golf overall, both sides of the game I expect, whichever one they choose to compete in.

reply
Trans women who have been on hormone therapy for at least a year have no overall advantage over cis women in most real, existing competitive sports. They have disadvantages in some of the most widely-sports-relevant capacities—compared to cis women—and small advantages in a couple of isolated abilities (grip strength).

They also have advantages in traits that across the population correlate positively with some broadly-sports-relevant capacities (e.g., lean body mass, both absolutely and as a share of total body mass, lung volume), but the actual sports-relevant capacities these correlate with on a population level (strength, endurance, etc.) they don't have an advantage on. There are studies that have detailed some of the low-level reasons for this with regard to oxygen use and other factors.

reply
Maybe the trans men issue gets less attention because they have already been excluded from both women's and men's events?

I assume trans men are administered testosterone as part of their medical care, and that's already universally banned from competitive sports.

Men are stronger and faster and not just a little bit. If you allow men in women's sports, (basketball, soccer, boxing etc) then women will not be competitive in those sports.

Yes but trans women on hormone replacement therapy are not as strong as cis men across the board.

There's no "culture war against trans people". It's obvious to anyone with a brain that sports were split between genders for a reason since the dawn of sport - sports can be dangerous and that keeps people relatively safe. If trans people would like to compete with others of their chosen gender, the they should just start leagues for their chosen genders. Simple, really.

I don't say this often: Oh, come on.

Obviously there is both a culture war against (and for) trans people, and also non-hate-based arguments against trans women competing with biological women. Both things can be true.

reply
Also there has only been one (1) trans woman, Laurel Hubbard, who has competed in a women's event (weightlifting) and she not place.
reply
She didn't place at the Olympics but it's worth noting she was the oldest competitor by far, and this after she had cleaned up gold medals in numerous international competitions despite having a relatively thin background in the sport. She was expected to podium at the Olympics and it's not really clear why she performed so poorly (the only athlete in the division to DNF).

Mrs Hubbard's background, if you read it honestly, is great evidence for why this decision was the correct one.

reply
Indeed. Hubbard's trajectory in female weightlifting is entirely unprecedented: re-entering the sport after a fifteen year break, with a stronger performance than those of elite female weightlifters with decades of competitive careers behind them and who had won Olympic medals.

The only reason why this was possible is because Hubbard is male.

reply
Because trans men have no advantage in men's sport, whereas trans females do. It's not even about trans people at all, it's about preserving fairness in women's sports.

Before trans issues were widespread in culture, intersex athletes were also scrutinized. Hell, I remember when people were questioning whether having a testicle removed gave Lance Armstrong an advantage...

reply
>It's clear how insane this culture war against trans people is when you consider this only applies to trans women and not trans men?

I believe the logic is based on the fact that male athletes are stronger than female athletes.

reply
> culture war against trans people

A war? What you're seeing are at least two phenomena:

1. Practices, including their legalization, that are causing moral outrage.

2. Political actors of various political sides tapping into the emotional charge of the subject matter for other political purposes.

The second is commonplace and part of the political toolbox and doesn't need much analysis here.

The first, however, should surprise no one. The real question is why anyone would expect social and cultural changes that involve the normalization of the gender paradigm and the compulsory acceptance of it in concrete ways to be accepted without so much as a complaint. Of course you will see a reaction. Of course people will react when biological men are allowed in women's restrooms. One has to be detached from reality to find that shocking.

> this only applies to trans women and not trans men?

Because biological men are generally stronger than biological women, and we're not talking about some weak correlation here. That's one reason we have sex-segregated sports. If you wish to attack sex-segregated sports, you're free to do so, but I think this involves repressing truths about deep sexual differences for the purpose of satisfying an ideological impulse or aim.

> so many of these anti-trans efforts end up hurting cis women too, the ones who happen to look too masculine or have too high of testosterone.

How are such people hurt? By whom and in what way? A key presupposition seems to be unstated.

> Gender is not as straightforward as bigots and transphobes would like to think.

The first unmet challenge is to define "gender" in the first place. The trouble with your claim is that no one can come up with a coherent notion, let alone one that has any correspondence with reality. People are simply expected and commanded to comply; no one is ever given anything sensible they might comply with even if they wanted to.

reply
To educate others reading this, it's far from "obvious" how to classify gender in sports. Checking if they have the right "parts" physically doesn't do it. Checking for hormone levels doesn't do it. Even checking for Y chromosomes doesn't do it.

In my opinion the way forward is to stop trying to find arbitrary ways to define gender, and just start making competition classes based on whatever factors are relevant to the event. E.g. a women with high testosterone? They can compete with men or women with the same testosterone bracket. This would also let men with low-T compete fairly rather then be excluded from the games.

It's also relevant at what point other genetic changes are "unfair." There are absolutely genetic traits that give people HUGE advantages in various competitions. Just like the gender-related properties, these are natural and yet result in unfair competitions.

reply
If you have a Y chromosome your sex is male. It’s not a matter of opinion. Wikipedia isn’t exactly a bastion of conservatism and this is pretty clear: https://en.wikipedia.org/wiki/XY_sex-determination_system
reply
If you pay attention, your source has an asterisk of “typically” and “usually”, aswell as a distinction between phenotype and karyotype traits. While it is true that the majority of people with a Y chromosome are male, there are many people with Y chromosomes you’d call female because of their phenotype (which is what society primarily cares about), among other cicumstances.
reply
I specifically said sex. Gender is mostly undefined. If you say that gender is the societal presentation as male or female, but you can’t define male from female then what are you defining? Its the “trans women are women” contradiction.

For Swyer syndrome, A 2017 study estimated that the incidence of Swyer syndrome is approximately 1 in 100,000 females. Fewer than 100 cases have been reported as of 2018.

For both the genetic disorders, they would have to be beneficial or at least not an disadvantage, for elite sport activity in order to be an issue for misclassification. For a sex-determination system, they could simply add an exception for Swyer syndrome and postpone the decision until such individual presented themselves at an Olympic competition.

reply
The problem with your proposed 'fuzzy divisions' is that they're not compatible with the zeitgeist of 'seeing the best compete', and 'drug-free' sports, as there's no reason to disallow performance-enhancing-drugs if we're already splitting into divisions.
reply
Actually, you bring up an excelling additional argument for the sort of bracketing I proposed. It also works for drugs!

There is significant grey area wrt to "doping" too in the sense that a performance enhancing drug may express as a larger than normal amount of a naturally occurring substance. So did the person dope, or is that their natural genetics? In my scheme, WHO CARES!

Beyond that, I suppose there is the usual argument against more serious and non-natural forms of doping that it is physically detrimental to the competitors and by allowing it you are encouraging or pressuring people to essentially harm themselves.

Still, competition classes could be helpful in some of the doping grey areas.

reply
Total nonsense. Sports are separated by sex, not gender. Sex is a biological reality, whereas gender is made up nonsense hiding behind the fact that many people equate the word 'sex' to sexual intercourse. That allowed 'gender' to flourish and confuse people.

'Gender' in it's modern form, was coined by John Money, the psychologist/sexologist responsible for the genital mutilation of many children, and the suicide of at least one of them due to his involvement of sexualized behavior during 'treatment'.

reply
Thank you. But the Y test still seems sufficient. Every criterion will have false positives and negatives. With the Y test the false negative (you present as a woman but have a Y chromosome) is rare and the vast majority of cases are handled well. If you have this condition you must compete against men (given the Y chromosome test rule) or not compete. If you’re dying to be in the Olympics as a woman but have the Y chromosome, you’re just out of luck. Not everyone can be a concert pianist either. No rule makes things wonderful for 100% of humans. The Y test gets very close.
reply
There will always be outliers.

High level sports consists entirely of outliers. That’s kind of the point of the olympics. This newest rule is nothing more than a misogynist rule to turn the women’s division into the “no more than statistically average” division.

I am going to try to keep my response apolitical to try to avoid fanning a culture war. That Wiki is the exact reason we are in this situation because we are bringing up points for 1 in 20000 or 0.005% of the population. Any system designed around 0.005% edge cases is going to be so complex that it is functionally impossible to do in practice. That is why one side says the solution is "obvious" because we have a simple rule that covers 99.9% of cases and the other 0.1% is unfortunately effectively barred from high level competition. Note, high level competition already bars 99.9% of people. Even though the opposing side is correct in pointing out these edge cases, it does nothing to advance an actual solution.
reply
There are statistically around 15 women AFAB with XY chromosomes in the NCAA by those numbers (assuming no correlation between Swyer syndrome and athletic performance).

There are currently around 10 openly transgender women in the NCAA.

Small numbers either way.

reply
Except I proposed a solution, which you ignored (I'm assuming here that I'm your "opposing side".)

Also, there are a significant number of these sorts of arguments in high-level sports, probably precisely because these "0.1%" cases are exactly the ones that result in exceptional ability relative to norms. It's also curious that there is such obsession about naturally occurring genetic outliers with respect to females or gender but absolute silence about naturally occurring genetic outliers among men unrelated to gender. And surprise surprise the top athletes often have such outlier genetics!

If you're drawing a distinction between natural genetic difference related to only gender and no other factors then sadly it's exactly a culture war, not a war based in science or fairness.

Because in a specific minority of the population it disagrees with the gender assigned at birth for obvious reasons. There are plenty of resources you could read on intersex instead of lol at something you don’t understand

> Why did it take so long for something so obvious to be acted upon?

A few reasons:

1. Sex is not as straightforward as most people think, and what to do with intersex people is not clear.

2. Trans athletes are underrepresented at pretty much all levels of sport, and aren't actually winning that much, making it not actually an urgent problem.

3. The philosophical underpinnings that advantages due to differences in body development should be disqualifying is a little broken, since we do not consider Michael Phelps being double jointed as being an unfair developmental advantage.

In an event that is primarily focused on competitive fairness, what does inclusion have to do with it?

If playing sport is about fun, well-being, etc, then don't play in competitive events. You can't very well want to play in competitive events while complaining about competitive fairness.

reply
It feels one sided because the author is an outsider - as the author readily admits - "It has been brought to my attention, however, that my blasé attitude toward sports makes me an outlier".

Turning to some actual numbers - this 2024 survey tells us that only ~15% of respondents said that their children participate in club sports or independent training (note that the categories are not exclusive). The same survey also says that ~10% of respondants think that their child can compete in professional sports, or be a national level team member. Finally, a similar 10% say that the "only the best players should receive time in games" is a fair policy at your child's age and level.

https://www.aspeninstitute.org/wp-content/uploads/2025/06/Na...

I think the point of the article is to maybe highlight how large the gulf might be between an typical outsider (and looking at the numbers above... and reminding ourselves that only ~50% of American youth are involved in organized sports at all), someone who is somewhat "in the game", and those who are really playing it (that 10% from above).

reply
The problem for this argument is that there is no actual data that trans kids and specifically trans girls are any better at sport than other girls.

Literally no trans athletes winning anything. I think hacker news skews scientific so we can do the math, if say 1% of the athletes are trans we would expect them to win 1% of the medals in a fair contest. As it is, they don't even come anywhere close. There has not been a single olympic medal won by a trans athlete, so clearly they do not have some kind of magical advantage, in fact (and common sense would make this pretty obvious) they seem to have quite a statistical disadvantage.

reply
> The problem for this argument is that there is no actual data that trans kids and specifically trans girls are any better at sport than other girls.

There is considerable evidence that they aren't. But that's not really relevant, because you have to remember segregation in sport has never been about competitive fairness, it has always been about allowing those who are socially superior to avoid the embarrassment of having to compete in an environment where they might be defeated by their social inferiors.

It is why women were long banned from competitions, and then shortly after exclusion seemed to harsh for evolving attitudes, they were segregated from men. And it is why trans people are being excluded from competition now. It's why racial segregation in sport was a thing. When competitive fairness is raised as an argument for segregation, it is pretextual, not the real reason, so counterevidence is irrelevant.

reply

Why did Lia Thomas go from being nowhere near winning in the male division to getting fifth in the women's?

Fifth is still nowhere near winning. So she went from nowhere near winning to nowhere near winning.

Is your argument actually that women don't generally compete with men in sports because the sports don't want to embarrass the male athletes if they lose? If so, I suspect this is a bad faith argument, but if not, you can simply do a little searching to find that there is often quite a bit of difference between the performance of top tier male athletes and top tier female athletes. For example, no woman has ever run a 4 minute mile in competition and more than 2,000 men have and even about 30 high school boys have. I am sure you can find other examples.

What the IOC's new policy actually does is make male athletes ineligible for competition in the female category, with very few exceptions. These exceptions are for athletes who are technically male but have a disorder of sex development that confers no male advantage, e.g. CAIS.

If you try to define athletic divisions by sex, you're going to have a hard time. The world's best athletes probably all have some unusual biology. About 1.7% of people are not completely biological male or female. I would expect that proportion to be higher for Olympic athletes. Excluding 1.7% or 2% or 10% of the world's best athletes from competing would not be fair.

When I was growing up, I remember some drama because East German and Soviet male athletes were trying to compete as women.
