[Effects and mechanisms of bariatric surgery on sexual function in males with obesity].

Abstract

Obesity has been identified as one of the risk factors for male sexual dysfunction, and it also has a certain impact on fertility. For people with obesity, sexual function is an important aspect of quality of life, but it is often overlooked. Society's stigma against obesity exacerbates the psychological stress of patients with obesity and negatively affects sexual function. Current studies have found that bariatric surgery can reduce body weight and improve sexual function in patients with obesity, and obesity-related gonadal dysfunction is also improved or even subsided after surgery. However, attention needs to be paid to postoperative body mass management and mental health status of patients to prevent postoperative body mass recovery and reversal of sex hormones and sexual function. In addition, there is still controversy about the change in sperm quality after bariatric surgery, and there is a lack of research data on sexual function and sperm parameters and mechanisms after bariatric surgery. Therefore, this article reviews the latest research progress of bariatric surgery and sexual dysfunction, as well as related mechanisms and sperm parameters, to provide a reference for bariatric surgery in patients with obesity with sexual dysfunction.
