OBJECTIVE: To review the literature on the relationship between obesity and sexual function. METHOD: A search in the medical literature from 1966 and onwards was carried out through Medline and Embase for publications on obesity, in combination with Medical Subject Heading words related to sexual function and dysfunction. COMMENTS: Four prospective and seven cross-sectional studies were found describing association between obesity and erectile dysfunction (ED). One cross-sectional study was found describing obesity and female sexual dysfunction (FSD). The prospective studies on ED all demonstrated a direct association and so did five of the seven cross-sectional studies. The single FSD study did not find any relationship. Eight intervention studies on weight loss and sexual difficulties were identified. All included few individuals and results were mixed even if most indicated an increase of sexual activity among both men and women after weight loss intervention. CONCLUSION: Support for the assumption that obesity is associated with ED was found in both prospective and cross-sectional studies. FSD was not adequately described in the literature and prospective studies are needed here. Results from weight loss intervention studies are less conclusive, but also point toward improvement in sexual dysfunction with reduced weight.

PURPOSE: We reviewed the effects of obesity and long-term weight loss on nononcological urological disease, particularly urinary stone formation, erectile dysfunction, female sexual dysfunction, voiding dysfunction and urinary incontinence. MATERIALS AND METHODS: A literature search was conducted using Ovid's MEDLINE, accessed through Emory University's Health Sciences Library web site. The subject headings obesity, weight loss surgery, urolithiasis, sexual dysfunction, erectile dysfunction, benign prostatic hyperplasia and urinary incontinence were used as indices for the search. Articles published earlier than 10 years before the literature review (performed in summer of 2007) were not used. RESULTS: There is ample evidence to support an increased risk of urolithiasis in obese patients. However, the effects of long-term weight loss on urinary stone formation have not been studied as extensively in the literature. It is unclear whether the decreased food intake after surgical weight loss procedures may negate the associated risk of malabsorption and decrease the risk of urolithiasis in the long term. The incidence and severity of erectile dysfunction in men increase with obesity. Female sexual dysfunction also appears to be positively correlated with obesity, although the literature is less clear as to the extent to which this is true. Despite a scarcity of relevant data, preliminary evidence indicates that weight loss improves sexual function in men and women. Obesity is associated with an increased incidence of benign prostatic hyperplasia and subsequent lower urinary tract symptoms in men, as well as an increased incidence of stress urinary incontinence in women. Despite a lack of relevant data, there is preliminary evidence that stress urinary incontinence and benign prostatic hyperplasia may be reversible after weight loss. CONCLUSIONS: Despite the abundant evidence that indicates a correlation between obesity and several urological diseases, there is a paucity of data regarding the effects of long-term weight loss on these conditions. However, the preliminary data indicate that the detrimental effects of obesity are reversible, and that long-term weight loss may decrease the incidence and severity of urological disease. Therefore, further research is needed to elucidate the impact of long-term surgical and medical weight loss on urolithiasis, lower urinary tract symptoms and incontinence, and sexual dysfunction.
