Impotence, also known as erectile dysfunction, is characterized by a man's inability to maintain an erection during sex, according to the Mayo Clinic. While there are a number of popular prescription treatments available for impotence, it's important to see your doctor and determine the cause of the disorder to rule out serious complications.
Mental Conditions
Conflict and poor communication with a sexual partner can trigger erectile dysfunction, because the brain plays a key role in getting and maintaining an erection. Stress, anxiety and depression are other mental conditions that can cause impotence.
Heart disease
Poor circulation caused by heart disease is a common cause for the disorder. Clogged arteries, high blood pressure and obesity are often associated with impotence.
Medication
Various medications can interfere with blood flow and create erectile dysfunction.
Substance Abuse
Drinking alcohol and substance abuse can interfere with sexual performance, as can tobacco use.
Disease
Several diseases, including diabetes, Parkinson's and multiple sclerosis, can affect the penis and the ability to support an erection.
