Gender just means he THINKS he's a female, for competition purposes only of course. One's "gender" has no meaning and no merit.
Thing is has she physically been gender tested? I assume so and therefore she is female. Why would the authorities lie? Or is the arguement that she used to be a man? Is she transgengender? We will probably never find out the truth.
The only important issue is whether he's a women or not, and he isn't.
