Why does a member get up – an erection mechanism

Why does the member get up and how – the mechanism of erection.

If you look at how a member gets up with men, the one does not really cause particular surprise and delight, if you don’t observe this for the first time, of course!You must admit, it looks quite a simple and uncomplicated process, is it so? But this is just in appearance, that is, externally. In fact, if we consider an erection at the level of physiological and biochemical processes occurring in the body, then we will see a completely different picture, much more difficult and interesting. Outwardly, a simple phenomenon inside is an amazing and subtly -minded mechanism, the essence of which we will try to reveal to you in this article. And so why does a member get up or how an erection occurs in men.

Which allows the member to get up – features of the structure of the penis

In order to answer in more detail and most importantly, to answer the question: “How and why a member rises,” you need to carefully consider the structure of the penis, figure out how it is arranged and what is so special in it that it allows him to be so surprisingly transformed and performing such vitalAn important function.

So, as can be seen in the figure, the body of the male member consists of 3 components: 2 shares of the cavernous bodies located on both sides of the member along its length and the spongy body, which is also located along the entire length of the penis, but is located under the cavernous bodies, as if between them. The head of the penis is a continuation of the spongy body and consists of the same spongy tissues. So the main determining and extremely important feature of all these bodies is their structure. These bodies in its internal structure are very reminiscent of the structure of the sponge (washcloths) – they are porous, that is, they consist of many small cells surrounded by small blood vessels, which, under certain conditions, can fill these cells with blood, due to which all the cavernous and sponge body can significantly increase in insize.

How a blood system makes a member get up

As can be seen in the figure below, arterial blood in a member enters the four main arteries: two cavernous and two pre -rsal, located on both sides of the deep pre -rsal vein. Caves are supplied directly by cavernous arteries. Smal vessels come out of these arteries along their length, along which blood goes into the depths of the cavernous body and, if necessary, fills the blood of the same cells. Blood leaves the penis through the veins and one of the largest, into which the smaller ones flow, is a deep pre -rsal vein. And here, attention, another important point that allows erections not only to arise, but also support. As we know, blood not only comes to a member, but also leaves, comes the arterial (red in the figure) vessels, and leaves along the venous (blue). But if the blood left the member with the same speed that it came, then the erection would never have arisen and the member would never have risen. And the focus all is in the venous locking mechanism. As can be seen in the figure, when the blood actively begins to flow into a member of the caution and spongy body begins to fill with blood and increase, thereby passing the veins lying between and around these bodies, and the main deep pre -rsal vein is transmitted by the pre -rsal arteries lying on both sides of it, which whenincreased blood pressure becomes more in size. As a result, blood arrives faster than manages to leave. Under such conditions, in the cavernous and spongy body, a certain blood pressure is constantly maintained, which as a result increases these bodies in size and makes them solid. That is why the member gets up and continues to stand.

We examined the structure of the penis and its blood supply during an erection. Now it’s time to understand what makes the member actively be filled with blood. After all, blood begins to flow into it only upon excitement, and for some reason it does not flow there in a calm state. So what serves as a kind of control valve?

To answer this question, you need to consider another interesting and very important point. All vessels are covered with small smooth muscles that control the tone of these vessels. So, in the relaxed state of the member, the vessels in it are fascinated, that is, they are compressed by these muscles and the blood in them enters very slowly and in small quantities. And when a man is excited these vessels relax, expand and blood begins to actively enter them. But what makes these vessels relax? So we got to the biochemistry of this process!))

Biology and chemistry of erection

Before starting to talk about biochemical processes during an erection, we immediately note that erections are 3 types: reflex, psychogenic and spontaneous. And although the external result of these erections is the same (a member rises), the causes of their occurrence are slightly different. In the following example, we will consider the reflex and psychogenic erection, that is, when a man sees something, hears or imagines and as a result of this is excited.

So the reaction chain is approximately the following. A man sees, hears, feels or imagines something that begins to sexually excite him. Brain departments responsible for sexual functions respond to signals coming from the corresponding organs of perception (eyes, ears, nose, skin). From there comes the command of the adrenal glands and testicles to produce testosterone. Testosterone activates the work of the prostate, which converts that testosterone into a more active shape. Under the influence of this testosterone, as well as receiving a command from the corresponding brain of the brain, nerve cells located near the penis are injected into the blood nitrogen oxide (no), which easily penetrating through membranes of smooth muscle cells of the cave and spongy bodies activates guanilantcyclase (special enzyme), which inIn turn, contributes to the production of cyclic guanosine monophosphate (CGMF). But just the CGMF is the peculiar valve that opens the vessels in the penis and makes it so that the member rises in men when excited.

The main property of the Central Military Service enzyme is precisely the relaxation of muscle fibers by reducing the content of calcium in their cells and an increase in potassium content. Thus, the smooth muscles of the cavernous and spongy bodies, as well as the small muscles of the surrounding vessels of the penis relax and expand, allowing the blood to freely pour into them.  Blood continues to actively enter the member until the CGMF continues to be produced and act. At the same time, the member continues to stand and remains solid.

But this does not continue forever, true? As we recall, after a man ejaculates (cums), a member usually gradually begins to fall and an erection disappears. Why? The culprit of this is the enzyme phosphodesterosis (FDE), the level of which in the blood rises after the man ends. He neutralizes the CGMF. In fact, there are about 10 forms of FDE, but only FDE-5 is engaged in the decomposition of the CGMF. By the way, Viagra appeared as a result of unsuccessful experiments with FDE-5. Initially, this enzyme was planned to be used to treat heart failure, and men participating in testing a new drug as one joyfully noted a very important side effect – their member stood for a clock!!)) After that, the project was turned, but another was deployed – to create a pill for men suffering from erectile dysfunction. So actually appeared world -famous viagra pills.

Erection process from A to Z

Now, when we examined and dismantled all the features and components of this process, it would be time to unite all the details into one holistic picture and once again describe how and why a member of men arises when excited.

In an unexplored man, the member is at rest due to the fact that the vessels inside him are tense and the blood practically does not enter them. When a man is excited, the Central Military Service enzyme is produced, which relaxes and expands the vessels of the penis. Caves and spongy are filled with blood and increase in volume, while supporting the veins by which the blood should leave. Thus, the blood begins to enter the member quickly than manages to leave. As a result of this, blood pressure in a member increases and it increases in size and becomes more firm, gradually reaching a complete erection.

It would seem so much said, although the whole essence could be conveyed by the last written paragraph, where it was a multiple of its own why a member of men is getting up. However, without that the above piece of explanatory material, it would be much more difficult to understand this last paragraph. Therefore, we approached the description of this process thoroughly, so that, as they say, there are no questions left.

Why is it important to know?

“Yes, interesting material, but what a practical benefit from it?” – you ask. And the benefit is that, knowing how an erection occurs, how and why a member rises, every man will be able to more likely realize the role and significance of a healthy cardiovascular system, the role and importance of testosterone and health in general. After all, the lifestyle of most modern men is very far from that which contributes to their health, rather, on the contrary. Therefore, follow your health! We wish you all a strong erection and that the member stood until old age!)
