Transgender man wins women's 100 yd and 400 yd freestyle races.

Just because you say it does not mean its true like an awful lot of other stuff you say, who accepts exactly and what studies have been done to show a trans man taking drugs can compete against an elite level biological male athlete, they may close the gap but compete I will believe when I see it.

There have been many women athletes that have taken drugs and still not get close to elite mens level, Sonya O Sullivan was cost a gold because of one, Michelle Smiths times were no where near the mens level.

Her times did decrease after transition, I don't think anyone actually seriously disputes this, and it's clear that biological females can beat her, several already have. The point is she is now competing at a higher level as a female than she was as a male. Her times are within the elite level for women now, whereas when she competed as a male her times were not considered elite, but, in the next level below. As a male she was highly unlikely to qualify for the Olympics, as a female her times would give her a chance of qualifying up until the recent rule change. I have never said biological females can't beat transwomen, I've actually said the opposite in an earlier post, but, in the Lia Thomas case it does look like she retains an advantage which allows her compete with elite women

It's accepted that the testosterone doesn't give trans men an unfair advantage. There's a difference.

Yes but testosterone isn't the only difference between men and women but you don't understand any of this.

If you really want to go into it trans men are at an unfair disadvantage but I don't see anyone advocating for them.

Well at least they're all being treated equally then.

I still don't see anyone saying it is unfair on trans men having to compete against biological males. That's advocating for them to compete against biological males.

There's quite a bit of evidence to support the alleged biological superiority but you can't understand it given you believe men have no biological superiority in physical sports.

Men and women are different. The idea that sex isn't binary (female and male) because there is a small number of people who are exceptions to that rule, is like saying humans aren't bipedal (don't have two legs), because some humans have a leg amputated, or they were born without a leg. They are exceptions to the rule, but they don't change the rule.

Transgender people aren't exceptions to the sex rule. Some people with DSDs might be, but transgender people generally aren't. Sex is different from gender. Why is this controversial? Sex matters for top level sport, but gender is what matters for every day life. They need to be treated differently in some situations but not all.

It's well accepted that testosterone levels are only one of the reasons that's men typically outperform women in sports.

You're making the assumption that this should hold for trans women competing against biological women as well. That's a big assumption

Rubbish.

What advanyage does a Trans Woman have over a Woman. She had testosterone in her you say. Ever think that maybe she we did not want that.

Also as we take oestrogen we lose muscle mass and gain fat as well as still having to carry around a skeleton formed from testosterone unless we has started transition in the early 10s or younger before testosterone had any major effects.

So a Trans woman competing in any female sport is at a major disadvantage straight away as they have heavier bones to carry around and less muscles than they had to do it.

So yes they should be aloud compete in Wonans sports and no there is no need for a third category. That is just discrimination and stupid too.

If the trans women was never really a man in otherwords started to transition at 13 or 15 then they never experienced the effects of testosterone and are the lucky ones and should be able to compete in female sports too as they are females be it as girls or as Women of they are over 18 when they are competing.

There are a whole sweet of factors affecting performance, hormones just being one.

The difference in fast twitch fibres, endocrine system, cardiovascular etc

What your hormone levels are at when you are competing or training is only a part of it.

The IOC doesn't set rules in different sports. It will eventually come down to individual bodies and more of them are gravitating towards that open category option. It is a nod to the fairness approach and TBF the science is still very incomplete on all of this.

That's interesting
