No, they have testes.

They may or may not have.

Generally, so the ones that really do appear to be female, and people may believe that they're female until puberty when they start developing male musculature.

That's right.

Well, it can't.

If you don't make DHT, some body hair won't be produced.

You won't have full male typical levels.

You certainly won't have any facial hair.

Generally, I don't think you have male pattern baldness.

So the lack of facial hair really makes a huge difference because it gives a sort of more feminine appearance to the facial skin.

So DHT is important.

And part of why 5-alpha reductase deficiency is relevant now is because there are people who are sexed as female and are legally female who are coming from, say, a rural town in South Africa because they've been running as a female on female sports teams or boxing, for instance.

Yeah, this is obviously the case.

We're all familiar with it.

And that means that we really do need to understand the science there.

And the important thing from my point of view is that DHT has been pretty clearly shown not to be necessary for male typical patterns of musculature and other physical features that would give men an advantage over women.

Which is difficult because sometimes these people have been in a female social role depending on where they were born.

Oh, from birth.

So Bessie and Schellinger, Bessie and et al have done that experiment and there's no difference between blocking DHT and... No, they did it in humans.

I think you know his work.
