Many medical conditions and medications can cause ED.
Smoking, alcohol abuse, drug abuse, stress and depression may cause erectile dysfunction.  ED can affect the brain and nerves (neurologic) or may affect the arteries and veins (vascular).

The most common neurologic conditions which cause ED are spinal cord injury, lumbar disk disease, stroke, Parkinson's disease, multiple sclerosis, Alzheimer’s disease and pituitary disease. In addition, certain surgical procedures can injure the pelvic nerves.  Always discuss the affects of surgical procedures with your doctor for complete clarification.

From a vascular standpoint, any disease process that can affect arteries may also affect the arteries that supply blood to the penis. These vascular disease can be: coronary artery disease, cerebrovascular disease, peripheral vascular disease, high blood pressure, and high cholesterol levels.  Radiation therapy (to kill cancer cells) to the pelvis can cause damage to the blood vessels supplying the penis. Again, this should be discussed with your doctor.

Psychogenic causes of ED include:

  • Performance anxiety
  • Depression

Libido: is governed by psychogenic factors and involves all five senses
(sight, smell, taste, touch, and hearing) as well as hormomal factors. Low libido, or hypoactive sexual desire occurs in 15% of men and in about 20% of the general population, both men and women. Depression and anxiety may adversely affect one's libido, and depression is the leading cause of hypoactive sexual desire.
The hormone testosterone is the main hormone responsible for libido in men. Testosterone levels have an effect on libido and on sexual thoughts and fantasies.
