Nerve impulses “speed train” race to the center to different organs, causing breathing quickens, and your heart “flutter”. Increased blood pressure. Male body – penis – under the “guidance” of the brain centers is filled with blood, increasing many times (5 to 10 times) and tenses. This is how an erection occurs in men. Activating the head of the penis and emotional arousal leads to multiple reduction of the seminal vesicles, and then the release of sperm, thus the male ejaculate, so – orgasm.

Why is it difficult to influence the behavior of the penis?
A person usually controls his body is not bad: the hands and feet, even with his eyes closed completely subject to his will. However, we command, can only muscles attached to the bones. Although there are muscles that men unfortunately not subject. Located those muscles in the walls of blood vessels and internal organs. That’s penis just such controlled muscles and is virtually independent of the owner, as it lives its own life.
However, its behavior determined yet nerve impulses. If we imagine the nervous system regulation, it is more like us telegraphy. There is “order” command post appears in the form of electrical signals, which in turn runs over the wire, that is – the nerves. At the end of the line is “telegraph”, which translates these impulses into manhood orders. These instructions cause the member to contract and relax the muscles.
The penis consists of two so-called cavernous body. Past their walls are muscles, it is thanks to them these cavernous body capable of changing its scope. In the normal state – “sluggish”, the muscles of small arteries and corpus cavernosum are able to tone (weak reduction). Because they are constantly circulating blood, but in a small amount, which is insufficient to impart elasticity penis.
But during sexual arousal the situation changes dramatically. By the genitals are beginning to enter the powerful impulses, causing relaxation in the walls of arteries and the body member of the muscle fibers. As a result of the corpora cavernosa and the penis itself filled with arterial blood, thus increasing in size, that is – there is an erection.
It is necessary to pass the excitement and the muscles of the corpora cavernosa to contract, forcing the blood – is the end of an erection.
There is a substance, savoring the muscles relax the order, which is called – acetylcholine. This substance is destroyed rapidly by special enzyme. Over the rats performed the experiment and when they were injected with a substance that stops the action of the enzyme, the rats copulated hours. But these substances, however, are not selective.
In 1998, American scientists have found a solution to this problem. They even received a Nobel Prize for his discovery of the chemical link between specific muscles and acetylcholine. This material forms a nitrogen oxide, which leads to an erection muscle and relaxation of the corpora cavernosa. So pharmacists the opportunity to manage this process.
