Erectile dysfunction (ED) is the inability to obtain or maintain an erection of the penis, which is sufficient to be able to have good sexual intercourse. Erectile dysfunctions are very common and can occur at any age. Their occurrence, however, increases with age and especially men over 60 years have to deal with it.


Erectile dysfunction may have a physical or mental cause, or a combination of both. The distinction is usually not difficult to discern.
Physical causes:

Mental causes:


Some men cannot have an erection at all, while in other men the penis becomes slightly stiffer, but not hard enough for penetration. In other cases, the erection can weaken during sexual intercourse. Some men have sometimes a normal erection and other times no erection at all. How the problems manifest themselves, depends entirely on the cause.

Mental causes can be examined by excluding physical causes. Therefore, a piece of perforated tape is applied around the penis at bedtime. When an erection is encountered at night, the tape tears, which is proof that there’s no physical cause for the erectile dysfunction.


The following treatment methods can be applied:


The ultimate success of medical treatment depends to a large extent on the expectations of the man and how he and his partner are able to adapt to the treatment.
