erectile dysfunction

Erectile dysfunction (ED) or impotence, occurs when a man has difficulty with either getting or keeping an erection long enough for satisfactory sexual activity.

It is one of the commonest sexual problems in men, affecting about half of all men over 40 at some point. It becomes more common and severe as men get older.

Causes and Risk Factors

There are a number of causes of ED. In around two thirds of cases, there are physical problems affecting the blood and nerve supply to the penis. However, there is a complex relationship between physical and psychological aspects of sexual function. For instance, physical health problems can cause psychological distress that can have an additional effect on erection problems.
