Maybe at the next olympics, instead of women's 800m, we'll have low-testosterone 800m!
But that doesn't take into account the effects of testosterone during puberty.
Creating a male body with all its advantages isn't just negated by lowering the testosterone for 12 months.
I think that's part of the problem. The law says that you can change legally sex, but there are exceptions, and sport is one of them. It uses the concept that men have a physical advantage. But the IOC have conclude that this physical advantage is constituted by testosterone. And only by testosterone, it would appear.
Which doesn't seem to be the case, hence mediocre male athletes beating women's records.
peggy if you read all the explanations on the other thread, linked above, you'll see that there are two types of DSD which are similar. Both include having a Y chromosome. But, there is an additional factor that means you can utilise the testosterone made in one. That's the one that caster has.
There are some people who look exactly like women, despite the Y, for whom the testosterone cannot be utilised.
So although, technically, they would be considered male because of the Y chromosome, I don't think there's anyone pushing that point.
It's not the same in caster's case, because the undescended testicles produced testosterone during a male puberty.
It's different.
I can imagine it's quite distressing all round. But that can't stop people making decisions in sport.
