Erectile dysfunction or sexual impotence is when the male is not able to maintain the penis in an erect position for a period of time.
One of the reasons for this sexual alteration are organic causes, that is to say, of physical origin. For example, if little blood reaches the penis, there will be no erection. Therefore, vascular causes are a type of organic reason for erectile dysfunction.
The same is true if there are neurological and hormonal problems. In addition, the administration of certain drugs can also cause sexual impotence problems.
