Can a XX woman go through male puberty?

I think we have to be careful here. Although DSD is now the preferred medical term, many of the people who have these conditions still prefer the term intersex and describe themselves as such. They also may use the term I/VSC (intersex/variations of sexual characteristics). For example one of the main support organisations for individuals in the U.K. is called U.K. Intersex Association.

Correct. It’s not relevant to female sports. Just answering the OP’s question.

Genes can translocate all over the place - pesky buggers - so yes it is possible.

Astonishingly rare though, and irrelevant here anyway.

@Blisterly I think it's pretty obvious?

The boxers have XY chromosomes.

I don't think they do have a right to privacy over this, actually.

They chose to compete on the world stage, knowing it would be controversial.

The women fighting them deserve the right to informed consent (now that we have lost the common sense assumption that there would be no males in the female category).

Edit for typos

I’ve just been readying about Swyer syndrome, which is interesting.

so xy chromosome but female phenotype
functional female sex organs but no puberty of either sex
often tall
No ovaries but gonadal streaks.
can take hrt to induce female puberty
can carry a pregnancy with egg donation
ibe read some conflicting stuff about testosterone levels but think the amount of testosterone depends on how much tissue is in the gonadal streaks, so could be normal for a female or slightly higher.
medically classed as female from what I’m reading

so the Y chromosome won’t always give a male puberty.

as far as I know the boxers medical details haven’t been released and I guess they have a right to privacy.

Lol
at someone coming in to lecture us about DSD using the term “intersex” 🤪🤪🤪

I've been looking for that chart. Thanks.

She has no breasts

This discussion definitely has an air of eugenics.

No, that would be giving puberty blockers to girls who like football and short hair,

Don't be silly.

Scientific fact is that sex is binary.

@AllGrownUp1465 sex is binary though and the DSDs are sex specific

I feel like it’s gone beyond the whole trans debate, to people that are biologically born a certain way

Yes we are discussing biology and the developmental pathways of sex. Trans is irrelevant to this.

That's a stretch and a half.

Man beats up woman in the name of vanishingly rare karyotype which he may not even have but that's OK because talking about his potential conditions sounds like racism?

Chromosomes are very complicated

FFS GENES, sex development is determined by GENES!!

It's not always possible to tell but in this case it's very clearly a male body. Even just the muscle distribution and shape on the arms is different to a female who has done gym training to get a high level of muscle.

How broad the shoulders are, face shape etc are also noticeably not female.
There are cases where certain men can appear female (though it's usually easier for women to appear like a young man) but when there are clearly male features they can't pass as female as it just doesn't happen in females. It's the same as how experts can often identify bones as male or female without needing a full skeleton.

I find this whole thread super odd, it reminds me of the pseudoscience of race in the 19th century, or phrenology. It’s way beyond the trans debate.

Chromosomes are very complicated and from journal articles I have read, it’s not a straightforward binary. I don’t think we have an adequate understanding of them because scientists have not studied women’s bodies properly.

If someone has a vagina but is intersex are they allowed to be a woman according to this thread? No.

This discussion definitely has an air of eugenics. I feel like it’s gone beyond the whole trans debate, to people that are biologically born a certain way, being subject to scrutiny, the way disabled people, or certain ethnic groups were treated in early 20th century Germany.

Are we now going to start restricting the biological variation of humanity to make sure it is more uniform, to make sure it fits what makes us feel comfortable? God I hope not.

Looks like there's all sorts of disorders and they are all either male or female. Not sure how they all present or what it means for each individual

The suppression of oestrogen and the introduction of drugs like testosterone would account for this.

Post pubescence we're talking doubly mastectomy of healthy breast tissue.

If a person with XX chromosomes went through male puberty that would definitely be a difference of sexual development, yes! (Assuming you mean spontaneously went through male puberty, i.e., we're not talking about someone who was taking testosterone in order to do so - in the latter case it's not a DSD, it's being trans and using "gender affirming" medicine, and there might be a terminological question about whether we counted that as going through male puberty or as imitating male puberty.)

Emma Hilton on X is full of info on these disorders if you want to find out more

I mean not the point of this post but cross sex hormones given to young girls does bring on some things boys get in puberty? Do they take something to suppress the growth of breasts? Obviously still female though they don't grow male reproductive organs

Unlike most on this topic, this is a really interesting thread. Thanks to all the very knowledgable posters!

Maybe worth noting that the Y chromosome almost never crosses over during meiosis (where sperm starts out in life). Evolutionary geneticists use this fact to trace ancestry down the male line. In our family, the Y reveals an ancient Briton lineage for example. X chromosomes do however line up and exchange genetic material so if you want to trace female ancestry down through the ages then you need to use mitochondrial DNA which gets passed on exclusively in the egg, female to female (and to males of course from their mothers).

All those words to illustrate that the Y chromosome is a reliably non sex recombining chromosome. It isn't being exchanged back and forth from X to Y willynilly through the ages. It almost invariably stays put. Which is a long winded way to say SRY transfers are extremely rare 😊😊. Sorry, as you were...
