It's about androgen insensitivity.

Okay, so I come across this person on my reels during the night. Probably due to discussions here and the algorithm and Big Brother.

I also tried to do a search here but nothing come up about previous discussions. Might be the imperfect search functions.

Now unusually for me, I will give my actual position on what I'm about to say and ask.

I don't think trans women should compete with women in the majority of single sex sports events past a childhood grassroots level. Where it really doesn't matter, we should probably have those sports be mixed at a professional level to increase participation but that's another subject entirely.

When it comes to DSDs and the like, I think things like normal or average hormonal levels need to play a part in determining their participation. The athletes most discussed in here, I agree (somewhat reluctantly) they shouldn't compete with women. Reluctantly just because I think they are good athletes/people and haven't acted maliciously.

The person in the clip I have shown above, however, I don't think they are quite the same. I wouldn't begrudge them a space on a women's sports team, though from the sounds of it, they might not be very good, anyway.

I'm actually not sure if this is the clip of them I've watched as I watched them on Facebook. They talk about several of their aunts having the same disorder so they had some idea they would vs most people who have it not knowing until they get older.

So I guess I'm asking for people's opinions on this person and disorder when it comes to single sex spaces and sports.

Ummm…..

Genes usually seen in males with genitals that look the same as most girls' and some internal male structures
So males then….

Explain to me why I should accept your definition of the sex of people with CAIS rather than that of the NHS or Prof Robert Winston

Not according to the NHS

Because CAIS is only found in males. As has been explained often.

Do you have a link for that NHS quote please?

I did search for it but I couldn't find it.

Thank you

Here's the link.

You may also want to look up how Prof Robert Winston says sex should be determined. He says that SRY gene plus functional testosterone receptors is male and everyone else is female. Hes an expert in human sex and reproduction as well as being a sex realist

Why do you disagree with the medical consensus that people with CAIS are female?

Someone who has breasts and vagina from.birth isnt a man. It doesnt matter how many times you try to convince yourself that they are but people with CAIS are women in every way that it counts.

Unfortunately for your argument, it remains a fact only males can have CAIS or PAIS. So this person is not female. Apart from being female, how can one be a woman?

Quite a few posters on this thread are insistent that a person with CAIS is male but this is not the medical consensus. The NHS says the following

Complete insensitivity to androgens makes a person with XY chromosomes female. Partial insensitivity to androgens can mean that some people are male and others are female.

I've seen various discussions about the studies that show CAIS is over represented in sports and there is some doubt about whether the studies correctly distinguished between CAIS and PAIS which may mean that it's PAIS and not CAIS that is over represented. (The discussions were between sex realist biologists including Emma Hilton )

In relation to sports its the difficulty in distinguishing CAIS and PAIS that is a problem. I suspect that the people who used to scout for 5ard males to compete in women's sport have already started to look for PAIS males hoping to have them classified as CAIS.

They are not female. There is no such medical consensus let alone scientific one. At most doctors may agree to ‘treat as though they are female’ but you only need to look at the various maternity scandals to see what the medical profession think of women.

Men with medical conditions are still men.

They also lack that ability to process the testosterone. Having a male testosterone level means nothing if you cannot utilise that testosterone.

The person in the Instagram reel has said three important things - they have internal testes, they produce male levels of testosterone, they have XY chromosomes.
If they play sports, then they should be playing in the male category.

Exactly. CAIS is a league of its own.

Yes it is. Not part of the women league.

I do think CAIS should be treated an exception on many fronts but if female sport is to be one of those exceptions it has to be closely monitored with the understanding that if the result of that monitoring is an over representation that it's means there is some degree on advantage and therefore the exception can no longer apply.

It is sad that talented athletes have to drop their dream if they suffer injury or become ill in a way that impacts their performance.

It is sad that people of a certain physical type will never excell at certain sports e.g. an average height man won't become a basketball star.

But either sport is fair or we do away with any ranking and give everyone a medal for turning up.

She doesnt have superficial resemblance to a woman if she was born with all the external parts that I was. Trying to minimise that she is externally female bodied just makes you look like you are so desperate to Other anyone who doesn't fit into the little boxes you thought encompasses humanity.

It shows what motivates your opinions and it isn't science at all. It isn't even the championing of women.

superficial means at a surface level. If externally they resemble women but internally are male then they are men who superficially resemble women.

But you know the response will be that the NHS are wrong and have been captured, and GCPOSTERwomenztoilets3000 knows better

How do you account for their over representation then?

And the video you linked says that removing the testes is outdated and shouldn’t be done until there’s a clear need.

I understand your empathy, but don’t think it should allow men to compete in women’s sports.

I dont think they are overrepresented. Not people with CAIS anyway.

It is not ‘nuance’ to demand men be allowed to destroy women’s sports.

No they shpild.compete because in every way except for their chromosomes, they are female. They don't have any male.advantage in sport at all.

So some people should be allowed to compete in sporting classes they are not eligible for because it’s not their fault and we (women) should #bekiiind?

It’s not any man’s fault that he’s a man so let’s let them compete so they aren’t excluded and get hurty feelz?

Did you watch the video you pointed to?

It says the testes aren't removed these days.

They can cause cancer so are typically removed at a time where the oestrogen they produced can be artificially provided.
