The influence of obesity on ICSI outcomes in women with polycystic ovary syndrome

The objective of the study was to compare intracytoplasmic sperm injection (ICSI) outcome and gonadotropin doses between obese women with PCOS and non-obese patients with PCOS. This follow-up study represents ICSI outcomes in obese women with PCOS (BMI >= 30 kg/m(2)) compared with non-obese women with PCOS (BMI < 30 kg/m(2)). Obese (n=18) and non-obese (n=26) women with PCOS underwent long protocol pituitary suppression, ovarian stimulation and ICSI with fresh embryo transfer. Obese patients with PCOS required higher doses of gonadotropin (2994 IU vs 1719 IU; p < 0.001). Miscarriage rate was significantly higher in obese women compared with the non-obese women with PCOS (60% vs 6.7%, p=0.002). Our results are valuable for counselling couples before initiation of assisted reproduction techniques (ART).
