Just Wondering?
I know that certain drugs demote the production of androgen (testosterone) in males.
If one were to use such a drug to promote breast growth in a male (theoretically), wouldn't that shorten the male's life expectancy because of the fact that males are kept healthy by testosterone?
As for the answer that you have provided, it is different, because he used to be a female.
I mean, if here were biologically male, wouldn't estrogen shorten his life span?
I understand what your getting at, but it doesn't answer the really question 'If a biological male (originally male) takes hormone replacement will it shorten his life expectancy?
