Abstract
In recent years, there has been a paralleled increase between male obesity and infertility rates. Obesity is associated with impaired hypothalamic-pituitary-gonadal axis, aberrant semen parameters, and subfertility or infertility. Weight loss is strongly recommended for the management of obesity-associated infertility. Lifestyle modifications that include caloric restriction and increased physical activity have a short-lived impact. Bariatric surgery is a better and more durable weight loss alternative. Comprehensive information about the benefits of weight loss on obesity-associated male infertility following bariatric surgery is still emerging. In this review, we discuss the hormonal, physical and environmental mechanism contributing to obesity-associated infertility. We then assess weight loss approaches, which include lifestyle modification, medical and surgical approaches, that can improve fertility in obese men. This review focuses also on bariatric surgery for the management of obese men seeking fertility treatment. Anecdotal evidence suggesting that bariatric surgery can impair fertility is also discussed.
