Funny, but all jokes aside.. I don't think it's as simple as proclaiming that you are a different gender. I think you have to undergo estrogen treatments or testosterone treatments to compete. I'm under the impression these athletes go through pretty rigorous hormone testing. No that I think it's fair. I've spoken before on my thoughts about someone being born birth male that has completed puberty have a large advantage whether you then provide estrogen therapy or not. The growth has already occurred.
