Failures in the sexual life of men are more commonly called impotence. However, this is not quite true. Dysfunction doctors consider a condition in which a man under any circumstances, is unable to perform sexual intercourse. This, fortunately, does not occur very often. A coincidence or recurring problems with erectile dysfunction should be called erectile dysfunction.
Mechanisms of erection
Before you start talking about the problem of erectile dysfunction, it seems necessary to refresh your memory a little structure of the penis, as well as modern ideas about how it operates.
Penis consists of two cavernous and a spongy body. Cavernous body reminiscent of a spindle-shaped and are arranged next to each other, and the spongy body, which passes into the head of the penis, is beneath them. The bodies of the penis are not related by blood vessels. Every body has its own artery, on which it is delivered to the blood, and his veins, for which the blood flowing from it.
The bodies of the penis in their structure resemble a sponge. They contain many small gaps, or in Latin cavities. It is this feature of their structure and makes possible the phenomenon of erection. More information about the structure of male genitalia, you can read the relevant article.
When sexually aroused men in the penis following happens. The arteries that bring blood to the cavernous and spongy bodies, expand, and the veins that carry blood flowing, sharply narrowed. As a result, in the bodies of the penis, or rather, in their gaps, there are substantial amounts of blood, each gap is strained, and there is an erection. This state of the vessels retained throughout erection. At this time, all the tissues of the penis, with the exception of the skin, do not draw their blood supply, and are in a state of ischemia. With a very lengthy sexual acts over time this can lead to certain problems, which we'll talk.
