title: Stimulation of endogenous surge of luteinizing hormone with gonadotropin-releasing hormone analog after ovarian stimulation for in vitro fertilization.
abstract: The effect of induction of preovulatory endogenous surge of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) with intranasal administration of GnRH-analog (GnRH-a) in an in vitro fertilization (IVF) program is reported. The use of GnRH-a resulted in a significantly better percentage of replaceable embryos (91% versus 85%). The pregnancy rate was 51% in comparison with 32% in control cycles in which follicular maturation was achieved by human chorionic gonadotropin administration. There was no significant difference in the postoocyte recovery serum progesterone patterns between the two groups. Our results indicate that the induction of endogenous LH and FSH surge with GnRH-a may be successfully employed for final follicular maturation after ovarian suprastimulation without affecting the outcome of IVF adversely. Apart from being a more physiological approach to oocyte maturation, it also has potential economic and clinical advantages.
