What is erectile dysfunction?

Erectile dysfunction is when the mechanisms which allow the bloodflow into the penis to form an erection don't work properly. The messages from the brain are blocked in certain channels, whereas what happens when a man has got a full erection - certain channels block off, so that the blood stays in the penis. When you've got erectile dysfuntion, those channels don't close properly, so blood is able to leak out again and therefore the penis goes soft again. That is basically what it is.
