nope, not as far as I know anyway. It can increase levels of testosterone and luteinising hormone, but I have never read anything that wouls suggest it would affect mensturation. I dont think it changes the levels of oestrogen, follicle stimulating hormone or progesterone. In some species it can cause a pseudo-pregnancy, but not in humans
