[Sexuality in overweight and obesity].

The association between obesity and sexual dysfunction has been described in many studies. Neurobiological, hormonal, vascular and mental disturbances are the main reasons in male and in female gender. Sexual interest and desire, sexual arousal, orgasm, painful intercourse and premature ejaculation can be involved. Data for prevalence of sexual function disturbances in obese people are scarce and most studies were small. For screening of sexual function we recommend the International Index of Erectile Function (IIEF)-Score, which contains 15 Items for males and the Female Sexual Function Index (FSFI), which contains 19 items for females. Treatment of sexual function disturbances include lifestyle changes with an increase of physical activity, weight control, healthy eating and smoking cessation. Testosterone substitution in cases of real hypogonadism and treatment with PDE-5 inhibitors are well documented treatment options in male individuals. New treatment options for female patients with variable effectiveness are fibanserin, testosterone, bupropione and oxytocin.
