Review medicine

Patients come to doctors to receive complaints of violation of erection, often ask the question: “How often erectile dysfunction?”. That question is difficult, and easily. The simple answer usually is: “Well, as you surely know from the newspapers and other media, erectile dysfunction found one in four men older than 40 years”, etc. etc. In the same spirit. Actually, not so simple. The difficulty lies in the fact that, despite the huge number of sociological and medical research in this field the exact answer to the question about the prevalence of erectile dysfunction has been received and that’s why.

First, not every man is inclined to discuss their sex life with strangers.

Secondly, the number of patients have a satisfying their sex life despite the problems with erection, that is of questioning or survey, they view themselves as healthy.

And thirdly, the very nature of sociological research in this area can not give a complete picture precise answer to the question about the prevalence of erectile dysfunction.

For example, the famous German urologist Hartmut Porst wrote in one of his books : “For all sorts of data in Germany there are about 10 million men with erectile dysfunction. However, when trying to determine the source of this information, its trace is lost in the jungle of secondary and pseudo-scientific literature. ”

Nevertheless, studies on the prevalence of erectile dysfunction is not terminated and research data are regularly updated. Today’s most rigorous research in this issue is held in 2010 in the U.S. “Program for the Study of aging men in Massachusetts (MMAS)». In the course of this program was subjected to questioning 1,709 people aged 40 to 70 years. As a result of processing of the data yielded the following figures: minimal erectile dysfunction, which in principle do not interfere with live more or less a full sexual life were detected in 17% of respondents, moderate violations, which have a significant influence on the quality of sexual life are found in 25% of respondents and the complete impotence – 10%. Thus, disturbances of erection of different severity were detected in 52%   men.

In real terms this means that 18 million American men have a place of erectile dysfunction of different severity. Needless to say, the figure is huge! In this case the obtained data clearly show that the prevalence and severity of erectile dysfunction is strictly correlated with age, while not a sign of very old age.
High injury of the male population (common are injuries of the pelvic bones, which resulted in very often suffer from blood vessels supplying the penis), alcoholism and smoking of low-quality varieties of tobacco. In addition to these three causes of common risk factor for erectile dysfunction is psychological stress, which leads to a depressed mood, reduced sex drive in men and as a consequence – the development of erectile dysfunction. As a result, more than 30% of the male population over age 50 have pronounced erectile dysfunction, and the age of 60 complete impotence occurs in 25% of men. These dismal. But with the advent of “Viagra“, in our opinion, this alarming statistics can change for the better.

Speaking about impotence treatment, it is necessary to mention about such exotic ways, as the use of powders of some animals prepared from dried penises, implant a costal cartilage in a sexual member, applying of every possible erotic creams and ointments, and also the use in a crude kind eggs young calfs. Yes-yes! All these ways not our invention and actually them much more. And all of them were at various times applied at the different people, and some are applied and to this day. But it is exotic. And if to speak seriously for today in the world it is applied two groups of medical measures in struggle with dysfunction. First, conservative actions, (i.e. psychotherapy and rehabilitation, application of different medical products which “Viagra” and mechanical devices for achievement excitation concerns also), and, secondly, operative actions – i.e. any surgical operations.
So, as to conservative measures. As it was already mentioned at the answer to the previous question, the medicines most known until recently for struggle against . All these preparations have a number of lacks which essentially limit their application.
The separate chapter in treatment dysfunctions is use of different technical adaptations. Their basis make any compressing devices. The sense of their action is extremely simple: on a sexual member the transparent plastic flask which through a hose is connected to the compact pump puts on. The pump extorts air from a flask, causing strengthening of inflow of blood to a sexual member and as consequence – erection. But this way of treatment presently differently as a curiosity you will not name. Because if a prick in a member before sexual intercourse it still all right to rattle flasks, to buzz pumps before the most intimate event in private life of each person – it already, in our opinion, too. But, nevertheless, it exists actually that as it seems to us, once again proves, on what victim the person for achievement of pleasure of a high-grade sexual life is ready to go.
As to surgical ways of treatment they can be divided into three categories:
Operations on vessels of a sexual member which are directed on restoration of normal inflow and blood outflow in a sexual member (these operations are carried out by vascular surgeons). Such operations are especially effective at young men who have transferred a trauma of bones of a basin with damage of vessels which go to a sexual member.
Operations on elimination of curvatures of a sexual member (are carried out by urologists and cosmetic surgeons). These operations widespread since the curvature of a sexual member can be eliminated only a surgical way.
Operations on prosthetics bodies of a sexual member (it is carried out also by urologists). The given interventions are necessary to people with rough bodies after the transferred trauma, an inflammation or long applications папаверина in the form of pricks in a sexual member.

As you can see, the dear reader, an arsenal of ways of treatment in this sphere of medicine is wide enough and various.

However all these methods by the efficiency, availability and, the main thing,safety cannot go to any comparison with “Viagra” tablets.

So, a medical product “Viagra” (VIAGRA) developed by firm Pfizer International Inc., is the first accepted through a mouth pharmaceutical  means in tablets  which shows significant and authentic efficiency at vast majority of patients with frustration of erection. The active substance of a preparation is citrate of sildenafil.  The preparation is issued in the form of tablets on 25, 50 and 100 mg which contain, accordingly, on 25, 50 and 100 mg citrate of sildenafil.

Unlike other ways of erectile dysfunction treatment which provide carrying out of injections in a penis or other medical procedures, “Viagra” is a simple, convenient and easily applied preparation. At use of “Viagra” you simply accept one tablet when plan sexual contact.

As to the mechanism of “Viagra” action it consists in an increase of the blood quantity coming in a penis that helps the man to cause natural erection.”Viagra” operates only when the man experiences natural sexual excitation and when the sexual intercourse is finished, the penis naturally comes back in the weakened condition. In other words, “Viagra” operates only on natural mechanisms of erection occurrence and there is its indisputable novelty and a secret of huge popularity in it.  How “Viagra” has been invented?

In the history of medicine there are many facts when occurrence of surprising opening was result of accidental supervision or finds. Two brightest examples till now are an opening x-ray radiation and antibiotics.

In 1895 the German scientist Wilhelm Konrad Rentgen  paid attention to an unusual green luminescence in the  darkness of objects which shortly before it were close with a worked high-voltage cathodic tube for some time.

Also he paid attention to that there was a light-striking of the packed photographic film which also was nearby from a worked high-voltage tube. These unexpected supervisions had allowed the ingenious physicist to come out with the assumption of radiation availability which earlier was not known to mankind. Later on, as is known, this courageous assumption had been completely confirmed.
The history of antibiotics opening is a sequence of even more surprising concurrences. In 1928 the British researcher Alexander Fleming incidentally detected, that a kind of dirty mould destroyed almost all types of bacteria which he grew up for bacteriological experiments. However instead of subjecting the laboratory dishes for cultivation of bacteria of sterilization and to begin experiments anew, Fleming had studied properties of a dirty mould in the most careful manner which to us is known now entitled “Penicillin“. So antibiotics which have made revolution in medicine had been opened.

The discovery of “Viagra” became, apparently, the third greatest “accidental” opening in medicine. That fact testifies to it also, that all the discoveries about which there had been told above, awarded the Nobel Prize. The same high award in the fall of 1998 the researchers who had opened, besides other things, properties of a preparation “Viagra” had been awarded. The history of “Viagra” began in 1992 in  Great Britain, in the place Pfiser the Sandwich, during pharmacological researches of firm ” Pfiser”. Researchers were carrying out clinical tests of new medicinal substance – Citrate Sildenafil which was developed as means for treatment of some cordial illnesses.

Scientists counted on that citrate of sildenafil will assist the increase of blood inflow to a cardiac muscle and decrease in arterial pressure. However it was noted, that citrate of sildenafil did not render essential influence neither on blood circulation in a cardiac muscle (myocardium), nor on arterial pressure.

There were, that many patients of a male who participated in research, refuse to return sildenafil tablets, despite of the termination of testing. The reason for refusal at all these patients was one – all of them noted themselves sharp improvement of erection quality. Thus, despite of the minimal influence of a new medicine on blood circulation in a myocardium, sildenafil caused perceptible blood inflow to a man’s genitals. The researchers of pharmacological company ” Pfiser ”  concerned to this unexpected property citrate sildenafil with due attention and  managed to distinguish  a powerful tool in it  against erection disturbances. The new preparation received the name “Viagra” – the name was born as though as a result of merge of the words «Vigor» (authority, energy, force) and Niagara – the most powerful waterfall in Northern America.

Since 1993 the long-term clinical tests necessary for confirming of “Viagra” properties began. As a result of these tests high efficiency of “Viagra” for treatment of impotence and a high security of this preparation were proved. And as the natural ending – on March, 27th, 1998 Department of the USA on the foodstuffs and medicines approved application of “Viagra“
