Abstract
The aim of this study is to evaluate the effects of obesity on clinical outcomes in diminished ovarian reserve (DOR) patients undergoing intracytoplasmic sperm injection cycles. In this retrospective observational cross-sectional study, women admitted to current clinic with DOR undergoing intracytoplasmic sperm injection were divided into 2 groups according to the obesity. Patient age, body mass index, anti-mullerian hormone, baseline follicle stimulating hormone and baseline estradiol levels, antral follicle count, total gonadotropin dose, day of stimulation, number of mature (MII) oocytes, and clinical pregnancy were evaluated. There were no statistically significant differences between groups in terms of age, anti-mullerian hormone, baseline follicle stimulating hormone, baseline estradiol levels, antral follicle count, and clinical pregnancy (P > .05). Total gonadotropin dose, the days of ovarian stimulation were higher and number of MII oocyte were less in the obese group (P < .05). Logistic regression analyses also revealed that the days of ovarian stimulation and number of MII oocyte were significant factors in the study group. ROC curve analysis showed obesity is a negatively affecting factor in DOR patients. Obesity causes more gonadotropin dose longer days of stimulation, and less number of MII oocyte. However clinical pregnancy rate is not negatively affected by obesity according to the current study.
