First, this is not for women with high levels of testosterone. Hyperandrogenism is something else. You'll notice 'testosterone' only appears once in the entire pdf. Actually, this is just a legal cover all.
Men produce testosterone from their testicles. As a young man, you should now be aware that women don't have testicles. So ... how do women get hyperandrogenic? From where does the testosterone come from?
This is a way of saying instead that you exhibit the symptoms of virilisation. Facial hair, and enlarged clitoris, deep voice etc etc.
Its a way of saying, we know you are using steroids, we are going to use anatomists to determine that. We won't be able to prove you are using steroids because you are likely using an undetectable steroid or using masking agents or indeed might just not be using them at this very moment, but we are going to kick you out of the Olympics because its obvious to anyone with eyes that you are cheating.
this isn't new to 2012 by the way. the olympics introduced sex testing back in the 1960s as a direct response to the Press sisters. Now the Press sisters were twins who threw shot put and discus and javelin for the USSR in the 1960s. It will come as no surprise to you that they were WR holders and twice the size of any other woman. However, they looked like a couple of fellas.
It was said of both sisters that their gender could not be determined. Some even thought that they might be hermaphrodites — still another opinion was that they were being injected with male hormones in order to make them stronger. Detractors called them the "Press Brothers". After gender verification for all international sporting female events was made mandatory in 1966 (curtailed in Sydney in 2000), both vanished from the sporting scene.
They literally decided not to go to the olympics a few weeks before and never competed again. One actually joined the KGB. I don't know why I know that. I'm good at pub quizzes.
Anyway, its not about catching hermaphrodites. Its about catching drugs cheats.
