title: Immunoreactive renin variations during fertile and infertile hyperstimulated cycles with in-vitro fertilization and embryo transfer or gamete intra-fallopian transfer.
abstract: The concentrations of prorenin (PR) and active renin (AR) were determined sequentially during ovarian hyperstimulated cycles for in-vitro fertilization-embryo transfer or gamete intra-Fallopian transfer. AR and PR increased during the early luteal phase and PR was highly correlated with the progesterone concentration. In fertile cycles, AR increased more rapidly after HCG injection and AR and PR levels were significantly higher during the late luteal phase. These results confirm the role of the renin angiotensin system in ovarian physiology.
