Our research question is; could follicular fluid (FF) leptin solely or contemporaneously with other clinical, biochemical and sonographic adiposity measures predict the probability of having a live birth during ICSI cycles? .This is a prospective cohort study that enrolled infertile women without polycystic ovary syndrome scheduled for ICSI. At baseline, women had assessment of obesity using different metrics: clinical, serum biochemical, and sonographic. Clinical measures encompassed waist circumference and body mass index. Biochemical evaluation comprised assessment of homeostasis-model for insulin resistance, visceral adiposity index and lipid accumulation product. Preperitoneal and subcutaneous abdominal fat were measured using ultrasound and body fat index was calculated. On day of oocyte retrieval, pooled FF was sampled to assess FF leptin. Our primary outcome was live birth after one fresh embryo transfer cycle.
