It is commonly called impotence, although I don't think that men have to be sexually active to consider themselves 'potent' human beings. Erectile Dysfunction can occur for a range of reasons and commonly results in an ability to maintain an erection.
Erectile Dysfunction can happen to a man at any age, although it is more likely to occur in men as they grow older. Middle-aged men are most at risk of Erectile Dysfunction and it tends to affect them deeply as sexuality and self-esteem seem commonly linked at this age.
Erectile Dysfunction was once considered too taboo to discuss but recently, with advent of Viagra and an ad campaign involving the former football star and soccer Legend Pele, it is becoming more common that men are willing to talk about it and seek help.
The problem can be caused by physical issues, blood being unable to travel to the require areas or sustained. It can also be related to stress, poor self-image, negative thoughts and as the result of surgery in the prostate area.
Treatment involving counseling and medicine (such as viagra and other types of drug) may be used to treat the issue. However, seeing a doctor immediately will begin that process. Although these drugs can be purchased on the internet, it is not always the right solution to your particular problem. Go and see a doctor, ask for a male doctor if you feel self-conscious and ensure yourself that these days, it is a problem with solutions available.
