Impotence

Erectile dysfunction (ED) is the inability to get and maintain an erection that is sufficient for satisfactory sexual intercourse. ED is also known as impotence.

How common is erectile dysfunction?

ED is a very common condition, particularly in older men. It is estimated that half of all men between 40 and 70 years of age will experience ED at least once.

ED can have a range of causes, both physical and psychological.

Possible physical causes include:

heart disease,
diabetes,
high blood pressure (hypertension), and
hormonal problems.

Possible psychological causes of ED include:

stress,
anxiety,
depression and
relationship problems.

Prognosis

Many men will experience episodes of ED that improve without the need for treatment. Sometimes, persistent ED can be the result of a more serious underlying health condition, such as heart disease. In such cases, treatment will be needed to treat the underlying condition.

Other causes include head injury, which can result in low levels of production of the hormone testosterone. Treatment of testosterone can treat ED when it is caused by head injury.

Generally, the prognosis for ED is good. Some men will just need to make some lifestyle changes, such as losing weight and taking regular exercise. Other men may need to take medication such as sildenafil (known as Viagra).
