An Open-labeled Prospective Randomized Controlled Trial on the Effect of Different Regimens for Luteal Phase Support on Pregnancy Outcomes in Patients With Idiopathic Hypogonadotropic Hypogonadism
Luteal phase deficiency (LPD) accounts for most failures of assistant artificial reproduction (ART) and early pregnancy loss for patients with idiopathic hypogonadotropic hypogonadism (IHH). Luteal phase support (LPS) is one of the indispensable interventions in ART treatments for IHH patients, which includes progestin, estrogen, human chorionic gonadotropin (hCG), and GnRH agonists (GnRHa). We aim to verify additional hCG injection 48 hours following routine hCG trigger and ovulation for LPS on the basis of supplementation of estrogen and dydrogesterone could improve clinical pregnancy rate, cumulative pregnancy rate, live birth rate and the prevalence of early pregnancy loss and ovarian hyperstimulation syndrome (OHSS) by an open labeled, prospective, and randomized clinical trial (RCT) in IHH patients in a single center.
• Clinical diagnosis of IHH (primary amenorrhea (with or without a history of hormone supplementation therapy); basic LH levels \<5IU/L, FSH\<5IU/L or normal; no organic lesions in the hypothalamus and pituitary MRI).
• Women of childbearing age who desire to get pregnant
