I read somewhere in international sports, there was this woman who looks like a man that competes with women. She is a woman alright, but too strong for other woman athletes, so what the organizers did was to check her hormones. She was found to have none or very litlle woman hormones, so she was disqualified, she was declared a man in woman's body (crazy world). If this sex change pool player have no male hormones, probably she could play with women.
