In older men, physical causes play a primary role in 60% or more of all cases of erectile dysfunction. In men over the age of 60, the leading cause is atherosclerosis, or narrowing of the arteries, which can restrict the flow of blood to the penis. Injury or disease of the connective tissue, such as Peyronie's disease, may also interfere. Damage to the nerves of the penis from certain types of surgery or neurological conditions such as Parkinson's disease or multiple sclerosis may also cause erectile dysfunction. Men with diabetes are especially at risk for impotence because of their high risk of both atherosclerosis and a nerve disease called diabetic neuropathology. Other causes include the use of certain drugs, including certain types of blood pressure medications, antihistamines, tranquilizers (especially before intercourse), and antidepressants. Smoking, excessive alcohol consumption, and illicit drug use may also contribute. In rare cases, low levels of the male hormone testosterone can cause erectile failure. Finally, psychological factors, such as stress, guilt, or anxiety, may also play a role, even when erectile dysfunction is primarily due to organic causes.
