Diabetes Mellitus frankly increases the prevalence of sexual problems in men, mainly in the form of erectile dysfunctions. Its effects on sexual function of the diabetic women have been less objectively studied, due to cultural reasons and methodological difficulties. The different phases of the sexual cycle, as well as their physiological control, are similar in human males and females. Several studies suggest an increased prevalence of sexual problems also in diabetic females. Their rate seems similar to that of the males. An increased prevalence of Female Sexual Arousal Disorder has been found in 6 studies of 6 comparing diabetic to non diabetic females. Its main symptom was a deficient vaginal lubrication, making sexual intercourse unpleasant. This disorder is the female equivalent to erectile dysfunction. It probably results from similar mechanisms, involving damages in the vascular and autonomic nervous systems, as well as alterations in the nitric oxyde production and efficacy. The prevalence of Hypoactive Sexual Desire Disorder was also increased in most studies (5 of 8, significantly in 3). This could result from the increased prevalence of depression in diabetic females. The Dyspareunia's prevalence was not significantly increased (0 of 6 studies). Available figures are not consistent as regards the orgasmic disorders (prevalence increased in only 4 of 8 studies). No significant correlation of female sexual dysfunction with diabetes duration, balance, or complications has been found. Conversely some significant correlations with depression or poor acceptance of diabetes have been found, supporting a causative role of psychological factors. Although still limited the therapeutic options should not be neglected. Merely prescribing a water soluble lubricating gel may greatly improve the sexual life of couples. Doctors should talk themselves about sexual function with their female diabetic patients. Most of these are too much embarrassed to ask themselves their doctor, although their sexual problems may seriously interfere with their quality of life and that of their partner.
