What Is the Impact of Bariatric Surgery on Erectile Function? A Systematic Review and Meta-Analysis.

INTRODUCTION: Obesity is a worldwide public health issue that has severe psychological and social implications. Erectile dysfunction also is a prevalent clinical situation, and obesity is one of the primary risk factors for its development. AIM: To determine whether bariatric surgery can lessen erectile dysfunction in obese men because of evidence showing that weight loss in obese men contributes to decreasing erectile dysfunction and bariatric surgery contributes to significant weight loss. METHODS: A search was conducted using Medline, LILACS, Cochrane, Scopus, CINAHL, Embase, Web of Science, Eric, and EBM up to April 13, 2016. The authors selected by title, abstract, and full text. Scottish Intercollegiate Guidelines Network checklists were used for comparative studies to show the limitations and biases of each article. RevMan 5.3 software from the Cochrane Library was used for meta-analyses. Results were demonstrated with forest plots. MAIN OUTCOME MEASURES: The outcome selected was resolution of erectile dysfunction, which was analyzed by improvement in the International Index of Erectile Function (IIEF) score. RESULTS: Of 185 articles analyzed, 7 were selected for systematic review. Meta-analysis of two articles that evaluated erectile function showed a 5.66-point increase in the five-item IIEF score of patients who underwent bariatric surgery (95% CI = 7.88-3.45, I2 = 35%, P < .00001), demonstrating statistical significance. Meta-analysis of three articles showed a 4.10-point increase in the IIEF erectile function score of patients who underwent bariatric surgery (95% CI = 6.10-2.10, I2 = 0%, P < .0001), demonstrating statistical significance. CONCLUSION: Bariatric surgery leads to an improvement of erectile function. Glina FPI, de Freitas Barboza JW, Nunes VM, et al. What Is the Impact of Bariatric Surgery on Erectile Function?
