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.
Impotence: Impotence is a consistent inability to sustain an erection sufficient for sexual intercourse. Medical professionals often use the term "erectile dysfunction" to describe this disorder and to differentiate it from other problems that interfere with sexual intercourse, such as lack of sexual desire and problems with ejaculation and orgasm. 1
