How common are the symptoms?
Erectile dysfunction is very common in men aged between 40 and 70 but it can also affect younger men.
According to a recent study, one third to one half of all men in this age group have experienced erectile dysfunction at least once.
In younger men, the symptoms are often caused by anxiety, a lack of confidence or nervousness. Drinking and drug abuse also contribute to erectile difficulties in the short term and the long term.
