Abstract

In the present study, we investigated the impact of metformin therapy on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes in patients with polycystic ovary syndrome (PCOS). Metformin does not lead to any improvement in IVF/ICSI outcomes among patients with PCOS.
