Obesity is a growing problem worldwide. This review aims to summarize the literature on the effects of weight on sexual function in both men and women from the past 5 years. In recent population-based studies of men and women, no relationship between weight and sexual function was identified. However, in studies of special populations such as women with gestational diabetes, polycystic ovarian syndrome PCOS , pelvic organ prolapse or urinary incontinence, weight affected some aspects of sexual function. In women, surgical, but not non-surgical, weight loss was associated with resolution of some aspects of sexual dysfunction. In contrast, in men, both surgical and non-surgical weight loss improved sexual function.
