Lately the role of GnRH agonist as luteal phase support has been recommended by various studies though the mechanism is still debatable. LPD is evident among women receiving the COS treatment using the GnRH analogue. The role of luteal phase support in these cycles has also been recently elucidated.

It has been postulated that GnRH agonist might support the corpus luteum by stimulating the secretion of luteinizing hormone by pituitary gonadotroph cells or by acting directly on the endometrium through the locally expressed. Ovarian stimulation cycles using both gonadotropin-releasing hormone GnRH agonist or antagonist protocols have been associated with a defective luteal phase that can disturb embryo implantation 4. In fact luteal support with human chorionic gonadotropin hCG alone or as a supplement to progesterone has been associated with a higher risk of ovarian hyperstimulation syndrome OHSS.
