The impact of LH, E2, and P level of HCG administration day on outcomes of in vitro fertilization in controlled ovarian hyperstimulation.

Abstract The objective of this study was to evaluate the impact of luteinizing hormone (LH), estradiol (E2) and progesterone (P) levels on the day of human chorionic gonadotropin (HCG) administration on outcomes of in vitro fertilization (IVF) in controlled ovarian hyperstimulation (COH). In this retrospective study, 129 infertile women undergoing IVF/intracytoplasmic sperm injection (ICSI) treatments were included; these cycles were stratified according to LH levels of ≥ 1.12 IU/L or
