We previously reported a negative association between body mass index (BMI) and sperm motility and seminal alpha-glucosidase concentration (NAG), suggesting that epididymis may be a target organ for weight-linked alterations. In this study, we analyzed the possible association between BMI and semen quality in 4876 patients, including morbidly-obese and underweight patients, with no genitourinary diseases, alcohol or cigarette consumption or toxin exposure. We performed multivariate regression analysis (using BMI, age and abstinence as independent variables) and demonstrated that BMI was inversely and significantly associated with semen volume, total sperm count, motility and NAG (slopes: -0.01, -1.33, -0.18, -0.75; p
