Suspect gym cafe staff member is putting estrogen tablets in my coffee, doubt i can prove it. what effect would they have on a male, if the male is still growing could it lead to a wider pelvis?

Unlikely but avoid: This seems very unlikely to me, though it is possible (but why?). If you're really concerned all you have to do is not drink coffee at the gym=problem solved. As for effects on a male, there are many- here's a discussion by adolescent males who took estrogen: http://transgender.Tribe.Net/thread/ff273c5a-023a-4e45-813f-5ca5d418c0ac i don't think it would cause a wider pelvis ; you're not growing.
