Impotence is the inability of a man to achieve or maintain an erection that is sufficient to complete sexual intercourse. Impotence is a common condition that may temporarily affect most men at some time in their lives. If impotence is short-lived and does not recur frequently, it is generally considered normal. If impotence persists, impotence can result in complications, such as male infertility and mental health issues, such as anxiety and depression.
Achieving and maintaining an erection is a complex process that involves a complex interplay of psychological elements as well as processes of the nervous system and the circulatory system. In a normal erection, sexual stimulation or arousal triggers nerves to increase the blood flow in the penis, which enlarges, strengthens, and becomes hard. Normally, the penis will maintain the erection until after ejaculation or when sexual excitement has ended.
Impotence, also called erectile dysfunction or ED, can result from diseases that impede normal circulation to the penis, such as diabetes, atherosclerosis, alcoholism, kidney disease, and multiple sclerosis. Impotence can also be due to conditions that interfere with normal nerve impulse transmission to the penis. These include neurologic diseases and some types of spinal cord trauma. Impotence can also be caused or worsened by psychological causes, such as depression, anxiety, guilt, and low self esteem.
Other causes of impotence include testosterone deficiency, obesity, testicular trauma, and some surgical procedures, such as those for prostate cancer or bladder cancer. Certain medications, such as some high blood pressure medications, may also cause impotence in some men.
The primary symptom of impotence is an inability to achieve or maintain an erection sufficient to complete sexual intercourse at least 25 percent of the time. For more information on symptoms, refer to symptoms of impotence.
Making a diagnosis of impotence begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination and neurological evaluation. It also includes performing blood and urine tests and other tests that check blood flow to the penis. These tests help diagnosis the cause and/or any other conditions, such as diabetes, that may underlie impotence.
A diagnosis of impotence can easily be missed or delayed due to a variety of factors. For more details on misdiagnosis, refer to misdiagnosis of impotence.
Treatment of impotence varies depending on the specific cause of the condition, a patient's goals, and the individual case. Treatment may include medications, the use of special devices, psychotherapy, sex therapy, addressing underlying causes of the condition, and/or surgery. For more information on treatment, refer to treatment of impotence. ...more »
Impotence or "erectile dysfunction" is the inability to attain or sustain an erection
for long enough for sexual activity.
About 70% of cases of impotence are actually caused by an underlying disease,
such as diabetes or kidney disease,
rather than a mental or physical problem.
Secondary impotence from various drugs and medications is common.
Physical damage from injury or surgery is another common cause of impotence.
Psychological causes of impotence are estimated to be only 10-20% of cases.
Although psychological aspects such as anxiety and fear of sexual failure
are commonly associated with impotence, they are not usually the real case,
but are a reaction to having impotence. ...more »

Fear, embarrassment, and shame are key reasons that a diagnosis of impotence can be missed or delayed. In addition, many men do not seek medical care for a diagnosis and treatment because they assume that impotence is a normal part of aging.
