Resistin and follistatin levels have been found to be high in polycystic ovarian syndrome (PCOS) patients, that play role in pathophysiology of PCOS and pregnancy status of women having ICSI cycle. This study aimed to determine the relationship between the hormone levels and pregnancy outcome in PCOS and non-PCOS women undergoing intracytoplasmic sperm injection (ICSI) program. The study was done at Higher Institute for Infertility Diagnosis and Assisted Reproductive Technologies from 2022 to 2023. Eighty infertile women participating in the IVF/ICSI treatment. They were split to control (40 non-polycystic ovarian syndrome-PCOS women) and 40 women for PCOS group. They were subdividing to subgroups’ according to body max index (BMI; normal and overweight / obese). ELISA method was used to measure hormone level at day 2 and follicular fluid and serum at day of ova pick up. About 38.8% of study participants were got pregnant. Means of serum resistin and follistatin in day 2 and OPU were significantly higher in patients with PCOS and normal BMI level while follistatin at day 2 and in follicular fluid (FF) were significantly higher in participants who got pregnant. Follistatin level at day 2 > 9.89 ng/ml and in FF > 15.06 ng/ml and might be as a predictor for occurrence of pregnancy after ICSI. The cutoff point of follistatin level in the serum at day two and in FF at the day OPU was found to be a predictor of pregnancy following ICSI, while no correlation was found between resistin and pregnancy outcome.
