title: [Aromatase inhibitors--is it a new opportunity in the treatment of infertility?].
abstract: Aromatase P-450 is a key enzyme in the production of estrogens, that is, the conversion of androstenedione and testosterone to estrone and estradiol. Aromatase is a good target for selective inhibition. New aromatase inhibitors provide a good opportunity for successful treatment during infertility management. They have a potential to replace clomiphene citrate (CC) as the first-line treatment for ovulation induction. Applying aromatase inhibitors during assisted reproduction followed: reducing the FSH dose needed to achieve optimum controlled ovarian hyperstimulation (COH); improving ovarian response to FSH in poor responders; terminating positive feedback loop and improving ovarian response to COH in infertile case with endometriosis; improving implantation rates in assisted reproduction technology (ART); reducing estrogen levels to reduce the risk of OHSS during COH.
