Intersex

No because transwomen are men, intersex can be men or women and are born into a body that has anomalies. If a transwomen finds out they have a genetic anomaly then they can redefine themselves. Transwomen are born male and choose to transition at a later stage by choice.
I suppose technically intersex can do the same so if they are genetically male and identify as male they can transition at a later stage. But they will still be genetically male.
If you are intersex but present biologically as female due to the effect of hormones ( natural hormone blockers) once diagnosed you can choose. But what we shouldn’t assume is that they want to be women.
Nowadays the handling of intersex is much better and individuals do have a choice. It hasn’t always been that way.
It would be wrong to think that transwomen are in the same position though

I also self identify as intersex.

I agree that you either have a male DSD or a female DSD and blood testing will reveal these conditions.

I don't think it's fair to allow females with a DSD to participate in women's sports where there is a sporting advantage. No males with a DSD should be allowed because they're male.

I find it a fascinating field too, but I find much of developmental biology fascinating, not just the stuff related to gender development

I don't see why it's fascinating it's a disorder like many other disorders

I don’t think anyone thinks that someone who naturally develops female internal/external anatomy with XY chromosomes is in any way the same as someone who surgically mutilates perfectly healthy male anatomy to form a non functioning caricature of female anatomy.

im sorry if this thought experiment has made you feel vulnerable to this

I don't see why anyone would do that tbh but I'm sorry that you have to put up with that fear

You'll find that many of us here have had to become knowledgeable in this area because those with DSD's have been used as a gotcha by those that have little understanding of the subject.

I can understand your fear but from what in see from those campaigning in the area of sports, they have an extremely good understanding of the difference (fondofbeetles for example).

The general public generally don't have much of a clue and this site is most definitely not reflective of the general public, so asking your question on here will give you a biased answer.

"I'm certainly not going to quibble with Prof Winston. The reason for this (I think) is that foetuses are female by default, so if the SRY gene is faulty they don't (can't) become male."

This isn't true, it's something some people believe to be true because of nipples, but from the moment of conception the sex and chromosomes are present, if not then people wouldn't be able to sex select embryos to ensure they have a girl or boy.

Embryos contain DNA the moment they are conceived, when the sperm and egg combine their chromosomes to form a diploid zygote.

It’s absolutely fascinating to be honest.

There's currently another poster who says they are intersex and also that they prefer intersex to DSD.

It is possible to have chimerism where you have absorbed a twin and their genes can be detected. Also mosaicism can cause anomies in genetic testing. This can also happen after having children.
Some individuals can have mosaic downed syndrome which is only detectable genetically and the individual shows no physical signs.
Genetics is not clear cut.

Transwomen are males who identify as women.

People with DSDs are either male or female. There is no requirement to identify as anything.

Two very different categories.

I'm not going along with the thought experiment but I'm curious about your DSD. Are you happy to share more about it?

Yes of course it is. They think they're so clever but we've seen it all.

@Tootsurly I'm also curious. When you stated you were curious about the degree of knowledge people held about intersex conditions/DSDs you gave the impression you yourself would have a lot of knowledge in order to judge this.

However, and I'm not judging you for this as it's very common, you appear to have little understanding yourself. So how exactly would you draw conclusions? People could say anything and you wouldn't know!

This is incorrect. The ovum is intrinsically female but the sperm can be either x or y or variations. Once they combine they are almost always male or female.
I think what you are confused by is the expression of the genes on these chromosomes at a definitive point in development. The embryos may look the same but are programmed differently. Anomalies in expression cause DSD and it can be due to mutations of the gene or extra chromosomes or fragments of chromosomes.
Ultimately we are a chemical soup that produces male or female fetuses with a very occasional DSD. There are infinite combinations but the majority are incompatible with life.
How most of us make it past conception is a miracle in itself.

May I ask what it is you fear will happen?
