Additionally, in multivariate logistic regression analysis adjusted for age, BMI, infertility duration, AFC, fasting serum glucose level, stimulation type, basal FSH level, basal LH level and basal E2 level, a one kg/m2 increase in female BMI was associated with a 6.8% decreased possibility of live birth (OR 0.932, 95% CI 0.893–0.971; Table 1). This evidence concerns the gene PLOD1 and Infertility.
