Abstract
Erectile dysfunction (ED) is defined as die persistent inability of a man to achieve and/or maintain an erection sufficient for mutually satisfactory sexual intercourse, this may be complete or partial.
It was thought that erectile dysfunction is mainly due to psychogenic k causes, but tills concept has been changed after the new diagnostic modalities have been used.
Erectile dysfunction is a complex procedure involving the interaction of psychological, hormonal, neurological and vascular factors. Erection is essentially a hemodynamic process and so vascular diseases are leading causes of erectile dysfunction and atherosclerosis is the most common cause of vasculogenic ED.
Atherosclerosis is a systemic disorder that uniformly affects the vascular system even though clinical manifestations of vascular diseases rarely appear simultaneously in the same patient.
This is likely the result : of the different sizes of the arteries supplying different districts.
The j retinal vessels, being one of the smallest vessels in the body, ar-3 affected early by atherosclerosis before other vessels, so it is thought to be a predictor of other vascular atherosclerotic diseases such as coronary heart disease and crebrovascular stroke.
The likely-worldwide increase in the prevalence of ED and the social problem attached to the condition present a serious challenge for health care policy makers to develop and implement measures to diagnose and treat ED.
