My quesiton is two-fold. First, my doctor recently perscribed Accutance for the treatment of acne. I have not started taken it because my wife and I are trying to get pregnant. My doctor assured me that we have nothing to be concerned about, but I am still worried because of the chance of birth defects and low sperm count. Should I be concerned? Second, I am also in the middle of training for a marathon and I am also concerned that the accutance will effect my training. As I am trying to do as much research as possible, your thoughts are greatly appreciated.
