The true role of nitrogen monoxide in human physiology has become understandable only in the past decade. This gas is a vital chemical element of the body. Researchers found that the nitrogen monoxide is necessary for a large number of different physiological processes, such as the transfer of nerve impulses, immune reactions and regulation of vascular tone. Thanks to the duly expansion of penis vascular erection happens.
When excitation of penis occurs NO is moving from one muscle cell to another, conveying a signal to relax. During the relaxation of the muscle cells additional nitrogen monoxide is allocated, which, in turn, provokes a chain reaction in nearby biocides of muscle cells (artery walls and empty spaces). Each molecule of nitrogen monoxide transmits the same signal to each muscle cell, however much they are at the whole length of the penis arteries, involving another chemical compound-cyclical adenozinmonophosphoric acid- c-AMP) into a chain reaction. And when all cells of vascular walls simultaneously produce the cycling AMP, the muscles of penis begin to relax. Arteries extend and more blood flows to penis.
Erection occurs because of the overwhelming blood fills the penis. But there are men who are unable to have erection because of disorders. Here is a help for them-VIAGRA. This drug guarantees a concentration of cyclical AMF in the body, which is effective for increasing of arteries, and will support them in the expanded state for quite a long time. That’s why VIAGRA makes the erection to appear and last longer.
Erectile dysfunction can arise for a variety of reasons and often these violations being developed are just symptoms of another disease. In general, the reasons usually affecting the development of erectile disorders can be divided into five groups:
However, one should keep in mind that the combination of these reasons can hamper the finding out the main cause of erectile dysfunction. Most often the reason is senescence of the body.
Unlike other ways to treat erectile dysfunction, which imply injections into penis, or other medical procedures, Viagra is a simple, convenient and easy- to- use product. Using Viagra you just take one pill when planning to have sexual contact.
Regarding the mechanism of Viagra, it is to increase the amount of blood coming into penis that helps men to have a natural erection. Viagra works only when a man feels a natural sexual arousal and when sexual intercourse is completed, the penis naturally returns to the relaxed state. In other words, Viagra influences only natural mechanisms of penis erection and this is its undeniable novelty and the secret of enormous popularity.
What can you expect from Viagra?
If you still erect, but is occurs infrequently, and you are unsure of its resistance, then your chances that Viagra will help easier to achieve and maintain a firm erection, are up more than 95%. If you have no erection or it is quite unsatisfactory, still you have 70-percentage chance that you will get quite adequate and functional penis.
Not everyone will want to try Viagra. Some choose to act "naturally and spontaneously" always. Possible side effects can push the others. It cannot be used by those taking nitroglycerin or close to this compound, and those whose heart has been unstable, and who may suddenly take nitrate intake.
According to numerous studies and clinical trials for drug volunteers with various erectile dysfunctions Viagra has a high efficiency. However, some points should be emphasized. Effectiveness of Viagra depends much on the type of erectile dysfunction and opportunistic diseases. For example, if the drug is effective at vascular erectile dysfunction, then if the reason is the so-called pathological venous drainage, the results will be much worse.
Unfortunately, there is no and there can be no drug that can cure all diseases, or, as in our case, all kinds of erectile dysfunction. Viagra is not panacea, it can help in many cases but not all the patients.
Viagra is effective for patients with atherosclerosis, damage of nerves going to penis vascular and sugar diabetes. In each of these cases your doctor may help in the treatment of the disease. Only a doctor can assign the correct treatment and find the best means.
As with any other drug receiving t in the case of Viagra treatment side effects can appear. As a result of extensive clinical studies more than 3,700 patients showed good portability of the drug Viagra. Once again draw your attention to the fact that the simultaneous introduction of "Viagra", nitrate and nitrate donors of any drug form is contra-indicated.
Can the long-term prescription of drugs somehow harm? Can it lead to a certain depletion of mechanisms responsible for the erection? The question is often asked by healthy men wishing to try Viagra to make some diversity in sexual activity.
Frankly, there is no data and observing people, which have taken Viagra for a long time. In fact, the drug appeared on the market drugs only recently. It would be wrong to say that the long, in a few years, receiving the drug could not show any side effects. Even if it seems obvious. Nevertheless, we are quite optimistic about the future.
