“…The GnRH receptors are present in various ovarian compartments including the granulosa, theca, interstitium, and corpus luteum (CL) (20). A significant literature based on data from experimental animals as well as clinical observations suggest that GnRHa may have stimulatory effects on the ovary including oocyte maturation (7), ovulation in hypophysectomized animals (7), steroidogenesis, follicular luteinization, and prostaglandin accumulation in experimental animals (7,10,21,22), steroidogenesis (23)(24)(25), ovarian hyperstimulation (26)(27)(28)(29), and cyst formation in women (30). These effects appear dependent on the agonist dose as well as the stage of follicular maturation (9-13).…”
