Relation between Progesterone Level on the Day of HCG Administration and the Clinical Pregnancy Rate in Intracytoplasmic Sperm Injection Patients

Abstract

D espite the widespread use of gonadotropin-releasing hormone (GnRH) analogues for pituitary down-regulation, elevation in serum progesterone concentrations, still occurs at different frequencies on the day of human chorionic gonadotropin (hCG) administration for final oocyte maturation in fresh in vitro fertilization (IVF) cycles (Venetis et al., 2013; Huang et al., 2015). The aim of this study is to assess the relation between serum progesterone level on the day of HCG administration and the clinical pregnancy rate as a primary outcome, quality of embryo, quality of oocyte, fertilization rate and chemical pregnancy assessed by B-HCG level 2 weeks after embryo transfer as secondary outcomes.
