Sexual difficulties are common among obese patients, but only a few research studies have examined the relationship between obesity and sexual quality of life (QoL). The aim of this study is to investigate the efficacy of bariatric surgery to improve sexual function and related quality of life in obese men.


Prospective study including consecutive male patients undergoing bariatric surgery procedures, both sleeve gastrectomy and Roux en Y gastric bypass, between 2013 and 2017. Anthropometric parameters, biochemical and hormonal assessment and QoL questionnaires [International Index of Erectile Function (IIEF), Sexual Desire Inventory (SDI), Short Form-36 (SF-36) health survey questionnaire] were collected before and 12 months after surgery.


44 male patients were recruited in the study. 40/44 (90.91%) underwent a SG and 4/44 a RYGB (9.09%). Median age was 43.45 years. Waist Circumference, Hip Circumference, body weight and body mass index significantly decreased 12 months after surgery, with a median weight loss of 49 kg and a median BMI difference of 14.28 kg/m2 12 months after surgery. Basal glycaemia, HbA1c, basal insulin, triglycerides, HDL cholesterol and CRP levels significantly decreased, while FSH, total testosterone and SHBG levels significantly increased. IEEF total score was significantly higher 12 months after surgery. Univariate analysis identified SHBG, estradiol and inhibin B levels, IIEF erectile function, IIEF intercourse satisfaction, IIEF total and SF-36 physical functioning scores as significant negative predictive factors of sexual improvement. None of them reached the statistical significance in the multivariate analysis.


Sexual impairment in morbidly obese men represents an underestimated problem, with a high prevalence in the IIEF domains in our series. Bariatric surgery represents the most effective therapy of morbid obesity, having a tremendous impact on metabolic profile, sexual function and self-perceived QoL.
