The effect of serum luteinizing hormone on trigger day with a GnRH antagonist protocol in IVF/ICSI treatment

To investigate the effect of serum luteinizing hormone (LH) on trigger day with a Gonadotrophin-releasing hormone (GnRH) antagonist protocol in patients receiving in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment for pregnancy outcomes. We retrospectively reviewed the medical documents of patients receiving IVF/ICSI with fresh embryo transfers from the Reproductive Medicine Center of Peking University People's Hospital between January 2016 and December 2018.730 patients were included and divided into three groups by their serum LH level determined on trigger day. All patients were categorized into Group A, Group B, and Group C based on LH concentrations
