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: X
Background: 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 ...

Efficacy of Stop GnRH-Agonist/Antagonist versus GnRH-Antagonist Protocols in In Vitro Fertilization Cycles of Patients with Polycystic Ovary Syndrome: A Pilot Randomized Controlled Trial [PDF]

International Journal of Fertility and Sterility
Background: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder impacting fertility. Controlledovarian stimulation (COS) is a crucial step during in vitro fertilization (IVF) procedure to enhance oocyte retrievaland embryo generation. This

Clinical and Molecular Effects of GnRH Agonist and Antagonist on The Cumulus Cells in The In Vitro Fertilization Cycle: A Double Blind Randomized Clinical Trial [PDF]

International Journal of Fertility and Sterility, 2021
Background: Gonadotropin-releasing hormone (GnRH) analogues have been extensively utilized in the ovarian stimulation cycle for suppression of endogenous rapid enhancement of luteinizing hormone (LH surge). Exclusive properties and functional mechanisms

Comparison of clinical outcomes between the depot gonadotrophin-releasing hormone agonist protocol and gonadotrophin-releasing hormone antagonist protocol in normal ovarian responders

BMC Pregnancy and Childbirth, 2021
Background The gonadotrophin-releasing hormone (GnRH) antagonist protocol has some advantages, such as a simple method, short medication duration, and low incidence of ovarian hyperstimulation syndrome, but whether the GnRH antagonist protocol is ...

Progestin-primed ovarian stimulation versus GnRH antagonist protocol in poor responders: Risk of premature LH surge and outcome of oocyte retrieval

Journal of the Formosan Medical Association, 2023
Purpose: For poor ovarian responders (PORs), gonadotropin-releasing hormone (GnRH) antagonist was commonly used for prevention of premature LH surge during controlled ovarian stimulation (COS) over the past two decades.
