well i hope to offer a different opinion than some of the other members of this board. i understand what it is like to be a competitive athlete and i was wondering, do you suffer from CAH? The effect of the extra androgen on the male body is a slight increase in growth early in life and shorten stature because the bone plates fuse early. Other than that I am not sure that there is much of a relationship with the testes but I am female and not an expert in this area. I think it might be wise for you to talk to a dr about your concerns. hope that this helps.
