I feel like some of the people who talk about DSDs are getting their, I dunno gut feelings?, if not information about them from the sort of medical drama that was popular on TV some years back. The ones where a pregnant woman would go into hospital and the staff would discover she had two uteruses! With a baby in each!
I know there were similar episodes with young teen girls “discovering” after a scan for some other reason, that they had internal testes. I seem to recall this second type of discovery was treated the same as the first - that is, some people are born with extra fingers, or their heart on the wrong side of their body, or whatever. “Some women are born with internal testes.”
I genuinely think there are loads of people out there who think these are all versions of the same thing.
Rather than realising that a person, who people thought was a woman until they found internal testes, is not actually a woman with some weird setup of their internal organs, but rather a man (with some weird setup of their internal organs).
The athletes with DSDs in question may have been raised for a while as girls, but they are, in fact men. Calling them that may shock them, hurt their feelings, turn their world upside down. None of those things make them any less men.
