Abstract
As men grow older they note changes in sexual function and voiding patterns, both of these conditions may have negative impact on quality of life (QoL). Erectile dysfunction (ED) defined as persistent inability to attain or maintain an erection sufficient for satisfactory sexual activity, is a highly prevalent problem in aging men although it is a frequently neglected aspect of health care. Main predictors of ED are age, cardiovascular morbidities such as hypertension and coronary heart disease, hypercholesterolemia and diabetes mellitus. Recently, many epidemiological and community based studies have added the severity of lower urinary tract symptoms (LUTs) attributed to benign prostatic hyperplasia (BPH) as an established and an independent risk factor for ED.
