Preventing Growth Stagnation and Premature LH Surge Are the Keys to Obtaining a Viable Embryo in Monofollicular IVF Cycles: A Retrospective Cohort Study [PDF]
Journal of Clinical Medicine, 2022 How LH levels influenced the outcomes of monofollicular IVF cycles using different stimulation protocols was controversial. In this single-center, retrospective study, we analyzed 815 monofollicular IVF cycles between 2016–2022 using natural cycle (NC), medroxyprogesterone acetate (MPA) or clomiphene citrate (CC) in addition to human menopausal ...

Clomiphene citrate reduces premature LH surge in obese women during controlled ovarian stimulation: a retrospective cohort study [PDF]
Frontiers in EndocrinologyBackgroundClomiphene citrate effectively suppressed the negative feedback of estrogen on the hypothalamus and induces premature luteinizing hormone (LH) surge during controlled ovulation stimulation, while obese women often have impaired hypothalamic ...

Prevalence of an endogenous LH rise following final GnRH antagonist dose in the IVF antagonist protocol [PDF]
European Journal of Obstetrics & Gynecology and Reproductive Biology: XBackground: The GnRH antagonist protocol is widely used in IVF/ICSI treatments. It involves daily injections of a GnRH antagonist starting on stimulation day 5 or later to prevent premature ovulation by suppressing the endogenous gonadotropin surge ...
