Erectile dysfunction and nervous system

Introduction

Erectile dysfunction is one of the most common medical conditions as it affects a large number of men everywhere around the world. In most cases it occurs suddenly so it causes a lot of surprise and shock. Stress is often the cause of erectile dysfunction, and it is also one of the most common of another similar medical problem called premature ejaculation. One needs to understanding the anatomy of the penis and the way the erection actually works in order to be able to achieve one again and maintain it successfully.

Erection

The human brain sends millions of neural communications down to the spinal cord so that various different types of voluntary tasks could occur on a regular daily basis.  There is also a separate set of communications which can be held responsible for the control of the so called autonomic nervous system. Autonomic nervous system is in charge of orgasms, gooseflesh, blushing and various other types of visceral occurrences. This nervous system has two distinct parts and those are the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system is in charge of reaction to emergencies and stimulants, so it speeds up the breathing, boosts the blood pressure and increasing the heart rate and the sexual arousal. It is also in charge of epinephrine and norepinephrine. The parasympathetic nervous system is quite the opposite and it is responsible for all the vegetative and calm functions inside the human body. All the organs in the human body receive messages from both of these nervous systems, depending on the purpose and the occasion. The same can be said for the penis. The penis requires a careful balance of information from the two systems in order to maintain proper sexual function. The parasympathetic nervous system modifies the flow of blood to the spongy tissues in the penis and makes the erection possible. And that is where the sympathetic nervous system may start kicking in. Increased sexual arousal leads to the increased activity of the sympathetics all the way up to the point where the person is no longer in control of the things. All that may lead to the loss of erection.

Erections Gone Awry

A person may become too anxious so the parasympathetic input does not occur and the penis cannot become erect. This is referred to as stress induced scenario. Causes of erectile dysfunction are often classified as psychogenic and organic.
