What
causes erectile dysfunction ?
Since an erection requires a precise
sequence of events, erectile dysfunction can occur when
any of the events is disrupted. The sequence includes nerve
impulses in the brain, spinal column, and area around the
penis, and response in muscles, fibrous tissues, veins,
and arteries in and near the corpora cavernosa.
Damage to nerves, arteries, smooth muscles,
and fibrous tissues, often as a result of disease, is the
most common cause of erectile dysfunction. Diseases--such
as diabetes, kidney disease, chronic alcoholism, multiple
sclerosis, atherosclerosis, vascular disease, and neurologic
disease--account for about 70 percent of ED cases. Between
35 and 50 percent of men with diabetes experience erectile
dysfunction.
Also, surgery (especially radical prostate
surgery for cancer) can injure nerves and arteries near
the penis, causing erectile dysfunction. Injury to the penis,
spinal cord, prostate, bladder, and pelvis can lead to erectile
dysfunction by harming nerves, smooth muscles, arteries,
and fibrous tissues of the corpora cavernosa.
Medicines can produce erectile dysfunction
In addition, many common medicines--blood pressure drugs,
antihistamines, antidepressants, tranquilizers, appetite
suppressants, and cimetidine (an ulcer drug)--can produce
erectile dysfunction as a side effect.
Experts believe that psychological factors
such as stress, anxiety, guilt, depression, low self-esteem,
and fear of sexual failure cause 10 to 20 percent of erectile
dysfunction cases. Men with a physical cause for erectile
dysfunctionfrequently experience the same sort of psychological
reactions (stress, anxiety, guilt, depression).
Other possible causes for erectile
dysfunction are smoking, which affects blood flow in veins
and arteries, and hormonal abnormalities, such as not enough
testosterone.
