Comparison Between the Role of Follicular Output Rate and Preovulatory Count in the Prediction of Pregnancy in Women With Polycystic Ovarian Syndrome Undergoing Intra Cytoplasmic Sperm Injection (ICSI)

Our study is observational, we are observing data from routine measurements during IVF/ICSI. Our study does not assess IVF/ICSI as an intervention, we are evaluating the role of FSI and preovulatory count which are calculated by observing routine measurements during the IVF/ICSI procedure. 300 women with polycystic ovarian syndrome (PCOS) who are decided to be treated with ICSI. will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by follicle stimulating hormone (FSH) stimulation until the day of Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular output rate (FORT) will be calculated as: (FSI =PFC\*10000/AFC\*Total dose of FSH). FORT correlation to pregnancy will be compared to that of the preovulatory count number
