Restricted blood flow
Erectile dysfunction, also known as impotence, is not being able to get and maintain an erection which is firm enough to have sex. An erection comes about when the arteries in the penis fill up with blood. Experiencing difficulty with getting an erection periodically, does not always have to be a cause for concern. However, if it is ongoing, it could be due to an underlying health issue which you need to have treated. This condition may also serve as a warning for heart disease.
The blood vessels can widen to allow more blood to flow within them by responding to signals from endothelial cells: specific cells which are found inside the blood vessels’ lining. These signals can restrict blood flow to various organs, including the penis, even if the vessels are not clogged with cholesterol or any other substances. When the endothelial cells are not functioning, the blood vessels become narrow, regardless of whether there is any clogging or not, and this stops blood flowing to the penis.
Damage can be done to both the veins and arteries which supply the penis. Atherosclerosis (the narrowing of an artery from the build up of plaque), is the main reason, and is due to the constricting of arteries, which is responsible for PAD (peripheral vascular disease), stroke and heart attacks. Moreover, this narrowing, constricting action stops the blood vessels’ muscular walls from dilating and relaxing as they should, and this is why the quantity of blood which can enter the penis chambers to keep the penis erect, is restricted. Moreover, blood vessels are also affected by altered levels of blood cholesterol, and high blood pressure.
When veins are not able to carry the blood away from the penis during an erection, then it is impossible to keep it going. This phenomenon is known as venous leakage. It can be the result of blood vessel disorders as well insufficient penis muscle relaxation. Difficulties with erections may also be due to physiological, neurotic or psychological reasons. Disorders include diabetes or Peyronie’s disease, which is an increase in the amount of the scar tissue of the penis protein coat and cavernous tissues. In the case of psychological factors, muscle relaxation can not be achieved when accompanied by a feeling of fear, or a neurotic disorder.
