The inability to attain or maintain a penile erection sufficient for sexual intercourse is a common problem experienced by a third
of men over the age of 40 years. Erectile dysfunction (ED) is a debilitating disease which can have profound psychological effects
on personal relationships and the social well-being of the affected individual. The diagnosis and evaluation of sexual dysfunction
has been well described, and several validated algorithms are available to quantify the classification and severity. The International
Index of Erectile Function and the Sexual Health Inventory for Men questionnaires are commonly used in the initial assessment
of ED. Several risk factors have been linked to the pathophysiology of ED. Endothelial damage has been the focus of many recent
studies. An evaluation of cardiovascular status, in addition to the administration of questionnaires to men with ED, might reduce
mortality and improve sexual quality of life.
