In human we are using the ovarian ovulation induction (superovulation) to treat the infertility problems which actually were due to an-ovulation. But the complication of ovulation induction protocols are over-ovulation or we called it ovarian hyperstimulation syndrome (OHSS). In this part we are looking to register the effect of fenugreek aqueous extract (FSA) in superovulation. By other word, we are scientifically searching to find a plant origin product that can prevent complication of ovarian superovulation. This is a big promising research in infertility treatment. This is the third part of our serious studies where we proved, in the first and second parts, the anti-fertility effect of FSA. We found that FSA can successfully decrease the signs of ovarian over-stimulation and that in the same time decrease the chance of OHSS.
