How Viagra Works

As you understand, we will talk about drugs that increase potency or, in the language of doctors, used to treat erectile dysfunction, or impotence. This problem is very urgent, because every year in our country people are sexually active with less frequency. On average, about 30% of men between the ages of 30-35 already have erection problems and cannot live a normal sex life. At the age of 40-50, this percentage increases. According to the research results of the company - manufacturer of condoms, from 40 countries, Greeks, French and Italians are most often sexually active. On average, men of reproductive age in these countries have 130-140 intercourses per year. In Ukraine, this figure is only 10-12 times a year. Of course, there are men who have sex more than once a month, but there are many who have not had sex for years and do not see this as a problem.

How Viagra Works

A bit of history

The drug Viagra appeared recently, about 15 years ago. A German firm was researching a drug for the treatment of cardiovascular diseases, invented by a German pharmaceutical firm. One of the side effects of the drug was the appearance of an erection in the presence of sexual arousal. In the course of further development, Viagra appeared. Since then, the drug Viagra has saved many families, brought pleasure to many women and men.

What does Viagra affect?

What is interesting about the drug - when there is sexual arousal, an erection occurs. That is, Viagra is designed to increase the blood supply to the penis in order to achieve and maintain an erection.

If a man took the drug, and his genital organ did not take combat readiness, then he did not have sexual arousal. Excitation arises from direct contact with a woman of interest to a man: caresses, hugs, kisses, inhalation of pheromones, etc. Then, under the influence of Viagra, an erection appears, which the same drug maintains and holds throughout the entire sexual intercourse. After the end of intercourse, arousal subsides, and the drug again ceases to work.

Whom Viagra will not help

Since sexual arousal depends on testosterone levels, the drug is less effective for people with low levels of the male sex hormone.

The drug has little effect on men with certain diseases, for example, diseases of the inner lining of blood vessels (endothelium). If the endothelium produces little substance that is a mediator of erection, then Viagra also works badly. This is observed in patients with diabetes mellitus, in patients with metabolic syndrome.

The drug is contraindicated in women.

Viagra is ineffective for people with severe atherosclerosis. With this disease, the vessels cannot dilate, and after all, an erection is an expansion of the arteries of the penis.

What are the contraindications

Sometimes in the media you can find news that someone died from Viagra. In fact, the person did not suffer from Viagra, but from the load that he gave to his body during coitus. After all, sexual intercourse is a kind of stress for the body, with a load on the cardiovascular, respiratory, muscular system, and the central nervous system. If a person, for health reasons, cannot bear these loads, then Viagra has nothing to do with it.

Medical contraindications include allergic reactions to the composition of the drug, intolerance to individual components, as well as diseases in which it is contraindicated to live sexually.

What besides Viagra?

After the invention of Viagra, other drugs with similar effects appeared. The next drug was Levitra. It has fewer side effects, more affects the vessels of the penis and less on others (from Viagra, there are headaches due to the concomitant expansion of the vessels of the head, there is swelling of the nose due to the expansion of the vessels of the mucous membrane). The third drug is Cialis (Tadalafil). This drug has already been invented by the Americans, and it has a fundamentally different formula. "Cialis" acts for 36 hours due to the fact that it has a longer half-life in the body. If it is used 2 times a week, then you can live a normal sex life all week. This does not mean that an erection is observed all 36 hours. As mentioned above, it occurs only when there is sexual arousal.

No matter how popular methods of treating impotence are advertised, not a single medicinal herb can reach the level of Viagra. Plants are adaptogens that, in small amounts, can increase testosterone production, increase blood supply, blood circulation, increase defenses, muscle strength, etc. There are no phytopreparations of the Viagra level that directly affect the vessels of the penis, and cannot be.

Viagra: pros and cons

Sildenafil (the original drug has the trade name Viagra) affects only the natural mechanisms of an erection.

Scientists have been developing a new drug to increase blood flow to the heart muscle and lower blood pressure. However, he did not live up to expectations. But it was noted that this drug provides a tangible blood flow to the male genitals, and, as a result, improves the quality of erection. This drug was named "Viagra".

The active substance of the drug is sildenafil. Currently, many drugs have been registered in the Russian Federation with this active substance. It works only when the man is naturally sexually aroused, and when the intercourse is over, the penis naturally returns to a relaxed state. In other words, the drug affects only the natural mechanisms of an erection. It was in this that its indisputable novelty and the secret of the enormous popularity of Viagra was.

How Viagra Works

Studies have shown that sildnenafil may help:

  • patients with psychogenic erectile dysfunction;
  • with diabetes;
  • with atherosclerosis;
  • with damage to the nerves going to the vessels of the penis;
  • with spinal cord injury and other concomitant clinical conditions;
  • people taking a number of medications at the same time, etc.

But, unfortunately, the drug cannot cure all types of erectile dysfunction. In any case, before taking any medications, you need to consult your doctor.

When should you be careful?

Everyone has heard about sildenafil or "Viagra". But few people know about the side effects and serious consequences of uncontrolled intake.

Caution in the use of sildenafil is necessary for people who are going to control various mechanisms after taking it. Sometimes, after taking the drug, a person may experience a rapidly passing change in color perception with a predominance of blue colors. In this regard, the management of one of the American airlines forbade its pilots to take Viagra an hour before flights.

People with severe diseases of the cardiovascular system (heart failure, angina pectoris, impaired cerebral circulation) need to be especially careful. They need constant medical supervision. Sexual intercourse is a serious physical activity for a person with cardiac problems. This should be borne in mind if symptoms such as pain in the heart during physical exertion and / or at rest, memory and mental impairment, have progressed over the past few months. Those who have suffered a heart attack or stroke should also take a serious approach to the issue. This means that you should definitely consult with your doctor about the advisability of taking sildenafil.

There are some men who should not take this drug. Because sildenafil is involved in nitric oxide biochemical processes, it can interact with other drugs called nitrates, which are used to treat heart disease. Therefore, any man who takes nitrates in any form should not take sildenafil under any circumstances.

Caution should also be exercised in those patients who have previously had priapism. Although to date there have been no reports of the occurrence of priapism while taking sildenafil, patients who have a predisposition to its occurrence also need serious medical supervision.

As for the effect of sildenafil on healthy men who have heard about the miraculous drug and want to satisfy their curiosity, then, according to the experts of Pfizer, the developer of Viagra, the drug has no effect on them! That is, if you feel some kind of revolutionary breakthrough in your own sexuality while using the Viagra pill, then, most likely, you should go for a consultation with an andrologist. This does not necessarily mean the presence of any disease, but the examination does not hurt.
