Arterial blood flow to the cavernous bodies is an essential component for the development of an erection. The causes of arterial insufficiency of the corpora cavernosa are divided into 5 categories:

* Atherosclerosis
* Traumatic occlusion on the level gipogastralnyh and penile arteries
* Cavitary deficiency
* Arterial spasm
The effectiveness of microvascular arterial bypass surgery highly variable according to different authors, ranging from 20% to 80%. Such significant variations in performance dependent on the diagnostic criteria, principles of patient selection and the type of operation.
The essence of this type of surgical treatment is to create a bypass arterial blood flow to the penis.

Mechanism of erection
In ancient times, ancient Greek philosopher and scientist Aristotle assumed that the erection of the penis was advancing in the process of filling it with some "miracle gas." At the same time, medical experts claimed that there are some sculptures, represented in the form of women, who made all efforts to fill this "miracle gas" the penis of their partners. This is so ancient idea.
Modern science, much less medicine, no longer believe in such fabrications. What would nevertheless look into the matter, as happens errektsiya, let's talk a little about how the male sexual organ is arranged.
Member is a root, body and head. An erection occurs due to the "cavernous" bodies, or as they are called "cavernous" body. The functioning of the sexual organ depends on its blood supply and innervation. The rush of blood in the cavernous body is due to the pair of arteries. Nerves and other order viagra arteries, located in the side rear of the vein member. The penis has muscles, which act as fixers root penis to the bones of the pelvis and abdomen. The "cavernous" blood from the arteries of the body comes from the so-called paired arteries phallus and depart on a spiral arterioles, small veins. These veins are very important to maintain the elasticity, we'll discuss this later.
As we already know, the elasticity and resilience penis depends on the corpus cavernosum. They consist of numerous cells, which form a connective tissue septum. They represent a complex three-dimensional grid. However, when the penis is in a relaxed form, the small arteries and arterioles, which fall into the very cells of cavernous bodies narrowed. It is because of this condition, the blood does not reach the "cavernous" sexual organ of the body and he thus raslablen.
When a man is excited, the nerve endings in the soft tissues of the penis receiving a signal from the spinal cord and brain. It widens blood vessels, thus greatly increasing the flow of blood, from which and an erection. When sexual stimulation stops, the blood moves away from the penis, which leads him into a relaxed state.
From this it follows that if the blood vessels, for whatever reason, are functioning properly, a man can not properly achieve sexual arousal - erection - and extend it.
