Men and Smoking
Factors such as age, blood pressure, cholesterol levels, diabetes, and body mass lead to erectile dysfunction. Men who smoke more than 20 cigarettes daily are at a much higher risk for ecertile dysfunction. Associated with erectile dysfunction is the build up of plaque. This plaque prevents blood flow through the vessels. The more cigarettes a man smokes, the more likely they are to develop erectile dysfunction.
