Tobacco, alcohol or drug use: All three of these substances can damage a person's blood vessels and/or restrict blood flow to the penis, causing ED. Smoking in particular plays a large role in causing ED in people with arteriosclerosis. Depression that accompanies ED is treatable. The first step in overcoming depression is to be honest with yourself, your partner, and your doctor. After depression has been brought out into the open, coping with it will be easier and less stressful.
