Erectile dysfunction (impotence)
Erectile dysfunction (ED), also known as impotence, is the inability to get and maintain an erection.
Erectile dysfunction is a very common condition, particularly in older men. It is estimated that half of all men between the ages of 40 and 70 will have it to some degree.
Symptoms
The main symptom of erectile dysfunction (ED) is the inability to get and maintain an erection for satisfactory intercourse.
ED should not be confused with ejaculation problems such as premature ejaculation, which is a condition where the process of arousal, orgasm and ejaculation occurs very rapidly.
