Influence of body mass index and polycystic ovarian syndrome on ICSI/IVF treatment outcomes: A study conducted in Pakistani women

Abstract

Obesity may establish a crucial barrier for effective fertility treatment in polycystic ovary syndrome (PCOS) females. To compare results of intra-cytoplasmic sperm injection (ICSI) in females with and without polycystic ovarian syndrome and further appraise the effect of obesity in PCOS females. A cross-sectional study from June 2015 to July 2016 included non-PCOS and PCOS (recognized by Rotterdam criteria) females who underwent ICSI. The PCOS were further stratified into non-obese and Obese according to the South Asian criteria for body mass index. Results were categorized on the basis of beta-human chorionic gonadotropin (β-hCG) and transvaginal scan into non-pregnant (β-hCG <25 mIU/ml), preclinical abortion (β-hCG >25 mIU/ml with no fetal cardiac activity) and clinical pregnancy (β-hCG >25 mIU/ml with fetal cardiac activity on transvaginal scan). In addition, reproductive outcomes; implantation rate, clinical pregnancy rate and miscarriage rate among obese and non-obese PCOS and non-PCOS patients were compared. Our results revealed 38.5% clinical pregnancy rate in non-PCOs females, 23.8% in non-obese PCOS females whereas 26.4% in obese PCOS. Preclinical abortions were found to be highest (31.5%) in non-obese PCOS females and were the lowest (26.2%) in non-PCOS females. In non-PCOS group and non-obese PCOS females 35.4% and 44.6%, respectively, failed to become pregnant. The success after ICSI in terms of number of clinical pregnancies was more in non-PCOS patients as compared to PCOS. Increase in body mass index reflected a negative impact on the reproductive outcome in PCOS patients.
