What Are the Causes of Erectile Dysfunction?

Erectile dysfunction (ED) is a cause for concern, regardless of the cause. The condition could signal other health problems. ED has also been called impotence. Erectile dysfunction is associated with complete inability to obtain or sustain an erection. Some men may experience brief erection. The condition is often associated with aging, but it may occur in younger men as well. Any condition that reduces blood flow to the penis can cause erectile dysfunction.

Physical Causes of ED

It is normal to experience difficulty or inability to get an erection occasionally. When the problem persists, it signals an underlying cause. Erectile dysfunction can be caused by medication, alcohol and drug abuse, diseases of the blood vessels (atherosclerosis), diabetes, obesity, spinal cord injury, low testosterone level and tobacco abuse. Other conditions that interfere with erections include multiple sclerosis, prostate cancer treatment, spinal surgery, trauma to the penis, Parkinson's disease and Peyronie's disease.

Emotional or Psychological ED

It is also common to experience anxiety related to sexual performance, resulting in inability to get an erection. Lack of communication between partners and everyday stress and fatigue can contribute to erectile dysfunction.

Risk Factors and Prevalence of ED

According to estimates, 15 to 30 million men experience erectile dysfunction. The causes of erectile dysfunction vary. Physical and emotional issues can be intertwined to cause inability to obtain or maintain an erection.
