âI am the fourth fastest 800-m runner in the history of the sport. And as far as I know, not one of the women who have run the 800 meter faster than me had my condition. I had differences in my body, yes, but it should be common sense that whatever my testosterone level may be, it does not make me male. And if speed was all about testosterone, then why wasnât I as fast as my male colleagues? An elite male athlete with natural testosterone levels in the accepted female range would still outrun me by the 10 percent to 12 percent performance gap.
