as far as I know, being ammenorehic will just mainly effect your bone density... however, I have thought about this many times through.... we discuss this in great detail in some of my classes... but we don't address if AS use could in effect take the place and not be as detrimental to ones bone density... I asked my proffessor what men have that prevents bone loss, and why it is so detrimental to a female to be without a period... basically she said that a female's body is used to relying on estrogen as her main source to supply bone density and without it, it can be of great danger.... However, for a man, other hormones take action to supply bone health... (damn, I wish I had better english to explain this)--
so I am thinking... if a female should weight train (ie. increase bone density), eat healthily, and also use anabolics, (kind of putting her body in a state at which a male might be in) which in turn stops her period, then I would ASSUME that it would not be as big of a danger as an anorexic that is starving, not training with weights, and eating her body from the inside out... duh...
My proffessor also said that there is only a slight danger of reproductive health damage.... the danger is there, but not as serious as if her bones were frail...
remember this is one of dieslgrl's theories... these pop up every once and awhile, so take it or leave it.. my thoughts.. not proof...
