There are multiple case studies about XY males with 5-ARD. Unless you mean about people with DSDs, in which case the same applies. You can find them on Pubmed.

I'm not going to answer a hypothetical when you don't understand the condition. You need to educate yourself about DSDs. Again, try Pubmed.

Mystery surrounds cabinet departure of Reform UK councillor Reform UK is being tightlipped about a move which has seen one of its members dropped from his cabinet job.

Oh look. Another one.

Literally this guy used to sell off-brand rolling tobacco in the pub in Swansea I worked in in 2003.

Read the paper. It explains the situation.
In 5-ARD the testes aren't streak, so cancer risk is nothing like as high as in eg OT-DSD. As that paper points out, some retain them. (As Semenya has done, though not for fertility.)

There have been no other studies of children at those ages which don't show male advantage.
If the disparity exists across a population then it's very easy to conclude it's sex-based. The "socialisation" argument is weak because all the children are competing - it's not a random selection.

I think they'd still have natal advantages of testosterone in the womb and childhood. World Athletics and World Boxing and skiing clearly think the same, because they don't offer an exception there.

In incredibly low doses. See the left-hand side of the graph? That's where females are, in the orange and the green curves.

There's simply no proper overlap with males.

They're no different from any other male. They'll have had testosterone from when they were in the womb.
And given the huge proportion of those who claim to be trans at a young age but then change their minds by age 18 or so, it's a bad idea to medicate young.

Either 1) everyone on all of the boards of rugby, athletics, swimming, cycling, cricket, tennis, hockey, etc etc suddenly became bigoted and moral panicked _at different times_ after years of not being so
Or 2) the science piled up and is completely undeniable.
I wonder.

I know people with DSDs.
I haven't asked your gender.
And my own situation is irrelevant here. Rude of you to ask, though.

Yes, it's binary. And also immutable. Mammals can't change sex.

Absence of SRY: female.
Presence of functional SRY without silencing mutations: male.
Others: it depends, but only male or female.

1. not "intersex": they're a male (XY) with 5-ARD, an autosomal recessive condition which prevents development of the external male genitalia but not of the testes.

2. You tell the medics they got it wrong, then. But they'll point out that it's *you* who's wrong.
No ejaculation: hence surgery.

I'm pointing out to people like you who don't have DSDs that using misleading words continues the confusion about the conditions such people actually have.

Patient consent has been considered key since well before that 2005 conference. Another part of your knowledge that's out of date.

1: You don't know about OT-DSD or its diagnosis. I've read the papers out of China about multiple examples.

2: I thought this was an example of 5-ARD. Usually requires surgical intervention. Example paper. https://www.endocrine-abstracts.org/ea/0071/ea0071028

Oh, that changes it. I thought you were describing 5-ARD.

CAIS will appear female, though in strict biological terms they're male, which can be relevant for health care. However they live as (infertile) female, and nobody has a problem with that. They're eligible for female sports.

Well, biologists. People who do the classification. It's the people who haven't studied the biology who think it's all handwaving inbetweeners.

Your example 1: OT-DSD: one or the other won't function. They'll be male or female, depending.

Your example 2: they're male. May even have motile sperm.

No: DSDs covers a much wider group of conditions than those classed (by those who insist on using the word) as "intersex", such as CAH (most common). It's not "a condition": each DSD is different. But those with DSDs are still only male or female.
Not "in between". This idea you have is wrong.

To be precise: 5-ARD is autosomal recessive, mutation on chromosome 2 or 5, and so XX females can get it. But in them it has no effect because dihydrogentestosterone isn't needed for female sexual development. They tend to have less body hair than normal.
XY 5-ARD is male, however - eg Semenya.

Yes, exactly. I mean, one could talk about how patriarchal it is: male administrators don't listen to women's complaints (86% wanted to keep SRY screening in a 1996 Olympics poll) and give women's places to men.

One where men lay claim to anything they want and deny it to women, I've heard.

An example of patriarchy would be demanding that males should be able to compete in female sports because they want to and nobody is allowed to say they can't because that would be "a ban".

The complaints about the Vietnamese volleyball player (my mistake) came from the Thai team at a tournament in Indonesia. The athlete refused to take a verification test.
So where's the racism?

Yes, because they will test negative for SRY. Have we been doing this for this long and you *still* don't understand the role of SRY, and why females don't have a functional copy, ever?

Women with PCOS don't have the pubertal explosion of testosterone males do. Never reaches male pubertal levels.
