What are the most common causes of erectile dysfunction (ED)?

ANSWER

The most common cause of ED is reduced blood flow to the penis due to chronic conditions such as high blood pressure, high cholesterol, and hardening of the arteries.

Psychological problems such as depression, anxiety, and relationship issues are also possible causes of ED. So are multiple sclerosis, spinal cord injuries, chronic back pain, and other neurological conditions.
