Abstract
BackgroundControversy remains despite several studies have discussed the role of bariatric surgery in improving male’s sexual function. This study aims to evaluate the efficacy of bariatric surgery in promoting male’s erectile function.MethodsPubMed, EMbase, The Cochrane Library, CNKI and Clinical Trails.gov were searched from database inception to May 2019. The language of publication was limited in English. The International Index of Erectile Function (IIEF) score and Brief Male Sexual Function Inventory (BSFI) score were set as the primary outcome.ResultsEleven studies with a total of 370 patients were enrolled in this meta-analysis. The results showed significant improvement in the IIEF score (erectile function: MD = 5.33, 95% CI 4.12–6.54; intercourse satisfaction: MD = 2.57, 95% CI 1.19–3.94; orgasmic function: MD = 0.50, 95%CI 0.60–0.94; overall satisfaction: MD = 1.67, 95% CI 0.78–2.56; sexual desire: MD = 1.27, 95% CI 0.61–1.93; total erectile function: MD = 7.21, 95% CI 4.33–10.10) and the BSFI score (erection: MD =2.53, 95% CI 2.39–2.67; ejaculation: MD = 1.40, 95% CI 1.28–1.51; desire: MD =1.40, 95% CI 1.32–1.49; problem assessment: MD = 2.20, 95% CI 2.06–2.34; sexual satisfaction: MD = 0.70, 95% CI 0.60–0.76) in obese individuals after bariatric surgery.ConclusionsThis systematic review and meta-analysis indicated that bariatric surgery could be effective in promoting males’s sexual function for obese individuals.

Summary
Controversy remains despite several studies have discussed the role of bariatric surgery in improving male’s sexual function. This study aims to evaluate the efficacy of bariatric surgery in promoting male’s erectile function. Epidemiological studies indicated that in 1995 erectile dysfunction (ED) affected over 150 million men worldwide and the prevalence will reach 322 million by 2025 [3], which could be a great healthy burden to the society for its high prevalence in the general population and tight association with life quality impairment [4]. Sarwer et al [11] demonstrated in their study that 36% of men seeking bariatric surgery reported erectile dysfunction. Moore et al [13] reported in their study 45% of obese men who seek weight reduction met diagnostic criteria of erectile dysfunction. Laumann et al [4] reported in the United States that the prevalence of sexual dysfunction in general male population was 31%
