What causes erectile dysfunction (ED)?

ED can be caused by a number of factors, including:

• Vascular disease: Blood supply to the penis can become blocked or narrowed as a result of vascular disease such as atherosclerosis (hardening of the arteries).
• Neurological disorders (such as multiple sclerosis): Nerves that send impulses to the penis can become damaged from stroke, diabetes, or other causes.
• Psychological states: These include stress, depression, lack of stimulus from the brain and performance anxiety.
• Trauma: An injury could contribute to symptoms of ED.

Chronic illness, certain medications, and a condition called Peyronie's disease can also cause ED. Operations for the prostate, bladder, and colon cancer may also be contributing factors.
