The majority of patients suffering erectile dysfunction exhibit various risk factors of vascular diseases. Erectile dysfunction used to be recognised as one of the consequences of vascular diseases in patients suffering heart attack or myocardial infarction. During the last decade, however, the role of endothelial dysfunction in the occurrence of erectile dysfunction has been signifi ed, and it has been suggested that erectile dysfunction may not be simply a consequence of vascular diseases but an indicator of future vascular problems. Erectile dysfunction has been known as "the tip of iceberg" of a generalised vascular dysfunction, which typically happens before serious vascular problems. Considerable evidence shows a link between erectile dysfunction and vascular disorders. Several theories have been considered for the association between erectile dysfunction and vascular diseases. One of them is the "artery size" theory focusing on the differences between the diameter of the penile artery and other arteries. Another theory is based on "endothelial dysfunction", which highlights inappropriate vasoconstriction as a cause of erectile dysfunction and vascular diseases. "Age" has also been reported to have pivotal role in the development of vascular dysfunction resulting in erectile dysfunction and ultimately vascular diseases. Another theory explaining the pathophysiology of erectiledysfunction and its relationship with vascular diseases focuses on the formation of atherosclerosis plaques.
