@donasmrs-- I'm in the same boat. This happens to many women, and is one of the reasons why some have difficulty getting pregnant. I think high FSH affects the quality of eggs which in turn makes fertilization difficult. Also for in vitro fertilization (IVF) to succeed, there has to be normal FSH levels.
My theory is that my high FSH levels is due to a medication I was taking. More specifically, I've been taking a selective estrogen receptor modulator (SERM) and my FSH started increasing after that. But my doctor doesn't think this is the reason.
I'm also taking supplements. DHEA, wheatgrass and Coenzyme Q10 are supposed to help reduce FSH levels.
