Smoking and Erectile dysfunction
January 31, 2007

A survey has been taken over 1368 men having age 50, 60, 70; it has been found that men having vascular disease are three times more likely to report erectile dysfunction.

Among ex-smokers, erectile dysfunction could signal vascular disease, Dr Rahman Shiri of the University of Tampere concludes

It has also been found that smokers not suffering from vascular disease were not at greater risk of erectile dysfunction non smokers.

According to Finnish Researchers report smoking can harm blood vessels which can lead to erectile dysfunction

But the mechanism by which smoking contributes to erectile dysfunction isn't clear: it could impair penile blood flow, interfere with the nitric oxide activity essential for erection, or lead to atherosclerosis (hardening of the arteries).
