Obesity does not alter endometrial gene expression in women with endometriosis

Abstract

RESEARCH QUESTION: Does obesity affect endometrial gene expression in women with endometriosis, specifically women with stage I disease? DESIGN: Differential gene expression analysis was conducted on endometrium from women with and without endometriosis (n = 169). Women were diagnosed after surgical visualization and staged according to the revised American Society for Reproductive Medicine (stage I-IV). Women were grouped by body mass index (BMI) (kg/m2) as underweight, normal, pre-obese or obese. After accounting for menstrual cycle stage, endometrial gene expression was analysed by BMI (continuous and grouped) in women with endometriosis, and in non-endometriosis controls. RESULTS: No sig..
