I remember back about 12 years ago when my ex-husband was using it the directions said not to use if you were female. I may be remembering this wrong, but I think it had to do something with if you were in your child bearing years. There is a female version, so I wonder why your doctor wouldn’t suggest that one? It seemed to work on my ex, but remember, when you quit, the effects stop also. My ex is now pretty much bald, or so I have heard. ha.
