Impact of Body Mass Index on Outcomes of In Vitro Fertilization/Intracytoplasmic Sperm Injection Among Polycystic Ovarian Syndrome Patients

Abstract

Background: The aim of this study is to assess the effect of body mass index (BMI) on outcomes of in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) among polycystic ovarian syndrome (PCOS) and non-PCOS patients. Methods: This was a retrospective cohort study that was performed in the Second Hospital of Hebei Medical University. Patients who were under 35 years old were included in the study and were divided into four groups based on their BMI. The number of retrieved oocytes, implantation rate, clinical pregnancy rate, miscarriage rate and live births among PCOS and non-PCOS patients were compared between different BMIs. Results: IVF/ICSI pregnancies in obese PCOS women had a considerably higher risk of miscarriage and low rate of clinical pregnancy than in non-obese PCOS pregnancies. However, in non-PCOS patient, obesity significantly elevated miscarriage rate but did not affect clinical pregnancy rate. Conclusion: Obesity in PCOS patients led to poor outcomes of IVF/ICSI.
