Oneneeds to understanding the anatomy of the penis and the way the erectionactually works in order to be able to achieve one again and maintain itsuccessfully.
The human brain sends millions of neural communications downto the spinal cord so that various different types of voluntary tasks couldoccur on a regular daily basis. There isalso a separate set of communications which can be held responsible for thecontrol of the so called autonomic nervous system. Autonomic nervous system isin charge of orgasms, gooseflesh, blushing and various other types of visceraloccurrences. This nervous system has two distinct parts and those are thesympathetic nervous system and the parasympathetic nervous system. Thesympathetic nervous system is in charge of reaction to emergencies andstimulants, so it speeds up the breathing, boosts the blood pressure andincreasing the heart rate and the sexual arousal. It is also in charge ofepinephrine and norepinephrine. The parasympathetic nervous system is quite theopposite and it is responsible for all the vegetative and calm functions insidethe human body. All the organs in the human body receive messages from both ofthese nervous systems, depending on the purpose and the occasion. The same canbe said for the penis. The penis requires a careful balance of information fromthe two systems in order to maintain proper sexual function. The parasympatheticnervous system modifies the flow of blood to the spongy tissues in the penisand makes the erection possible. And that is where the sympathetic nervoussystem may start kicking in. Increased sexual arousal leads to the increasedactivity of the sympathetics all the way up to the point where the person is nolonger 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 inputdoes not occur and the penis cannot become erect. This is referred to as stressinduced scenario. Causes of erectile dysfunction are often classified aspsychogenic and organic.
