Purpose: To evaluate whether high LH/FSH ratio has a clinical impact on patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) with GnRH-agonist/antagonist protocols or in vitro maturation (IVM) treatments.
Methods: We retrospectively reviewed all PCOS patients with day 3 LH/FSH ratio ≥1.5 who underwent IVF or IVM.
