A high prevalence of sexual dysfunction in men with T2 diabetes has been reported in studies. Erectile dysfunction (ED) is associated with an increased risk for cardiovascular disease, stroke, and all-cause mortality, independent of conventional cardiovascular risk factors. Coronary endothelial dysfunction is independently associated with ED in men with early coronary atherosclerosis. Early diagnosis of ED could help prevent emotional and physical discomfort in men and aid in identifying reversible cardiovascular risk factors. Screening of sexual dysfunction should become a part of routine care in the management of T2DM patients. We aim to assess 500 patients with diabetes with a well validated ED score (IIEF Questionnaire)
