The relationships between bariatric surgery and sexual function: current evidence based medicine

Abstract

Background 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. Methods PubMed, 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. Results Eleven 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. Conclusions This systematic review and meta-analysis indicated that bariatric surgery could be effective in promoting males’s sexual function for obese individuals.

The Italian Society of Andrology and Sexual Medicine (SIAMS), along with ten other Italian Scientific Societies, guidelines on the diagnosis and management of erectile dysfunction

“…Numerous strands of research have demonstrated that surgery-induced weight loss is correlated with higher T levels as compared to the increase obtained by lifestyle interventions only, suggesting a potential therapeutic role of surgery for the treatment of hypogonadism in obese males [ 218 ]. Otherwise, the effects of bariatric surgery on ED and fertility are still controversial [ 56 , 219 – 221 ]. A prospective cohort study of 32 men undergoing Roux-en-Y gastric bypass reported significant increases in total T, but non-significant improvements in sexual functioning, four years post operation [ 222 ].…”

Metabolic surgery in China: present and future

“…This occurs partly through reductions in adipose tissue, especially visceral fat ( Liu et al, 2018a ), as well as substantial weight loss, serum uric acid reduction, insulin resistance (IR) improvement ( Zhu et al, 2019c ), and amelioration of inflammation after SG ( Zhu et al, 2019b ). Furthermore, metabolic surgery promotes erectile function ( Kun et al, 2015 ; Liu et al, 2020 ). Patients with obesity who undergo metabolic surgery have higher chances of pregnancy, successful delivery, vaginal delivery, and fewer maternal complications during labor.…”

Sexual function and sexual activity in young total hip arthroplasty Chinese patients: A retrospective cohort study

“…Several validated instruments have been widely used to examine SF or diagnostic sexual dysfunction in either males or females, such as the Brief Index of Sexual Functioning for Women (BISF-W), the Changes in Sexual Functioning Questionnaire (CSFQ), the Female Sexual Function Index (FSFI), International Index of Erectile Function (IIEF) and the Brief Sexual Function Inventory (BSFI) ( 12 , 13 ). FSFI and BSFI are two validated questionnaires that have been used frequently to measure sexual function.…”
