A report from University of California at Irvine reviewed twenty years of studies and found that smoking tobacco causes impotence.
When you smoke tobacco, you inhale hydrocarbons that damage the lining of arteries to start plaques forming in their inner linings and slow the flow of blood. Nicotine constricts arteries to make them even narrower. When your arteries leading to your heart are completely blocked, you suffer a heart attack. When the arteries leading to a man’s penis are blocked, he is impotent. Arteriosclerosis is the most common cause of impotence in North America.
Many men are not afraid of heart attacks enough to make them reduce their weight to normal; control high blood pressure; eat a diet that is loaded with vegetables, fruits, nuts, seeds, beans, and whole grains; exercise regularly; and stop smoking. When they find out that smoking makes them impotent, perhaps they will change their minds. More on causes and treatment of impotence.
