Can a XX woman go through male puberty?

[DenmarkStreet]

The Facebook algorithms decided that I was a good object for an article on the Imane Khelif discussion which ended with the statement that some XX women go through male puberty. Or as it was described "the testosterone shower" which very much seem to suggest something quite brief. Is this even possible or just made up?

Of course not!
XX = female puberty

XY = male pubetty

XXY = male puberty also, this is typically a male with a DSD.

The Y chromosone will always give a male puberty even with the extra X

If you have a Y you're a guy....

Never encountered it in over ten years of working in medicine. However I am not a specialist in that area.

I’m discussing this elsewhere. Someone has just told me that:

“What “chromosome testing” would/should deny a woman a place in the competition? Remember, there are XY mothers out there, and XY women who have gained no physical advantage in their sport due to their chromosomes.”

Are there ‘xy’ mothers? How can there be if xy and xxy = male puberty?

SRY gene translocated onto X chromosome?

There are so many xy mothers out there that the possibility of 2 of them turning up in boxing matches against women is high.

Not.

The chances of a cheek swab kicking out a man are exponentially higher than the chances of it kicking out a birth-giving xy human.

But just like that the world collectively begins to doubt the evidence of its eyes and ears.

They are leveraging the vanishingly rare and quite the medical curiosity case where a person with Swyers syndrome carried a pregnancy to term with a donated egg.

This was managed with a huge amount of medical intervention. I mean herculean amounts of help to achieve this. Someone linked the case study in another thread and I can't remember which one. Interesting for sure.

As I understand it (and I am happy to be corrected by someone who is actually knowledgeable about this) Swyers syndrome affects people who have not gone through either male or female puberty but are technically male.

It's totally wrong of people to use this case as a gotcha, it's an outlier of a case in medical intervention but again as I understand it is to do with where the Y chromosome ended up but essentially still a failed male pubertal pathway.

In answer to RandySavage

According to Google there are yes.

'Discussion: In world scientific literature at least fifteen successful pregnancies with pure gonadal dysgenesis XY have been described. In spite of the expectation of diminished uterine capacity, children are born to term with a normal delivery weight.'

I think there's a very rare disorder called Swyer syndrome where they have XY chromosomes but a development problem causes the male pathway not to be followed and they end up with female genitals but no functional ovaries or testes.

A different disorder with XY chromosomes is where they are born with ambiguous genitals and may be thought to be female at birth but have no internal female parts and internal testes. At puberty the testes produce testosterone and they go through male puberty and are male.

I'm no expert though so this is my basic understanding of things

There are many different forms of DSD

I think there is some chance that this boxer could have XX chromosomes. But may still not qualify as female due to what has gone on with her body and her hormone levels. It does seem pretty obvious that even if she does have XX chromosomes, she has not gone through a typical female puberty.

The question is whether it’s possible for someone with xx chromosomes to go through male puberty? Can this ever happen?

Maybe this is a stupid question, but I can’t see how it’s obvious she hasn’t gone through female puberty?

XX plus sry gene would go through male puberty but be sterile I think.

But that's because of that pesky Y though isn't it? Question, not snark.

De la Chapelle syndrome.

No, it means the SRY gene, which is usually found on the Y chromosome is instead present on an X chromosome. So, 46,XX but phenotypically male.

But that's because of that pesky Y though isn't it? Question, not snark.

my understanding is no Y but the sry has translocated to the fathers X chromosome (or maybe another one of his chromosomes) when the chromosomes divide to make the haploid sperm. But I could be wrong on this - I just know that sry like all genes can translocate from the Y.

I’m no expert, but from what I see, the waist to hip ratio doesn’t look female - female puberty includes hip widening for childbirth.

Thanks to both @LaeralSilverhand & @TheHomeEdit

So although not the big Y, it comes from male genes then, just a quirk of genetics where something marked genetically speaking "male" is accidentally transposed over into the wrong chromosome "box" - if that makes any sense at all?

Looks male to me. Maybe the disorder I mentioned before which is 5ARD I think. Wrongly seen as female when born and then went through male puberty due to internal testes which gives him greater strength and power.

Someone on another thread helpfully posted this:

https://medlineplus.gov/genetics/condition/46xx-testicular-difference-of-sex-development/#causes

80% of XX males caused by translocation of SRY; 20% of unknown cause.

46 XX male syndrome, where the sry gene translocates onto the x chromosome passed on by the father.
They have testes so will produce some testosterone at puberty, but normally need additional testosterone as they don’t produce enough.

Thank you very much for this!

I get a bit uncomfortable with this. I know women of all shapes and sizes. As someone who didn’t properly develop breasts, but is a woman and has had a baby, I would hate to be judged for this. Same with my friend who is often confused for a man behind as she has no hips or waist, broad shoulders and short hair.

As far as I understand it all DSDs are genetically male with the exception of Turners syndrome (a single functional x chromosome) who are genetically female and present as such. Women with Turners syndrome are infertile and are very unlikely to be athetically gifted, as the condition comes with medical issues and short stature.

Not all people with DSDs and xy chromosomes go through male puberty, but no-one without a y chromosome goes through male puberty unless this is artificially induced.

The SRY gene basically determines whether an embryo develops as male or female. If it’s present (and functioning) you get a male, if it’s absent you get a female - females are the default, males are basically mutant females 🤣 So an XY individual with no SRY ends up phenotypically female (Swyer syndrome). An XX individual with an SRY ends up phenotypically male (de La Chapelle syndrome).
