Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient to complete sexual intercourse. In healthy men, sexual stimulation causes a series of physiological events that increase blood flow to the penis and results in an erection. Erectile dysfunction, or impotence, is classified as a medical disorder and may be a symptom of an underlying medical or psychological condition that affects blood flow such as atherosclerosis, depression, diabetes, high blood pressure (hypertension), high cholesterol (hypercholesterolemia), obesity, or spinal cord injury as well as side effects due to treatment for prostate cancer; ED also may result due to the use of certain medications or lifestyle habits such as excessive drinking or smoking.
