How Viagra Stimulates and Enhances Erections
Many men suffer from erectile dysfunction (ED) – the inability to achieve and maintain an erection long enough to be enjoyable and satisfying sex life. For various reasons ED is most common in men over 45 years. The sexual drive is often in older men, the drugs of various kinds can be reduced.
The most of us assume that the interest in sex gradually as we age, we are willing to accept ED as a natural state. But the fact is, the inability to maintain an erection for many men is the result of a treatable physical conditions rather than an actual loss of libido.
Until the early 1980s, most people – including most urologists trained – in fact, believed that ED was a mental or psychological problems. But in 1983, during a presentation at the American Urological Association, Dr. Giles Brindley showed that a penis by the injection of the drug phentolamine could be built. In a public demonstration, he used his penis to make the point.
Brindley had discovered that the penis by relaxing the blood vessels, which can be made consricted to normal. Once the blood vessels to relax, they allow more blood into the penis and inflated like a balloon, to form an erection.
It happens so gradually accepted that the ED result of physical changes in the adult male – not primarily mental or psychological conditions.
Viagra – the Mastery of the penis valve
Phentolamine – the drug used by Dr. Brindley is making a public erection – began to be used successfully in the 80s and 90s, but there are two problems with phentolamine. First, it is not selective enough to target only the penis, so the effects are unpredictable at other parts of the body. And secondly, the erection is not time to sexual stimulation. You can get an erection every time with phentolamine old, and you will have an effect until the drug wears off.
Viagra is the first drug for these two problems to overcome. (It was introduced in 1998 by Pfizer. The active ingredient in Viagra is sildenafil citrate.) No Viagra works by relaxing the blood vessels of the penis. Instead, promotes natural processes, if a man is sexually stimulated occur. It does this by controlling what we can “softener” call – the chemicals in the body is designed to go after soft erections.
It works something like this. If a man is sexually stimulated, his brain sends signals to the production of chemicals that relax the blood vessels in the penis to take effect. Consider it “hardener” as. Because the blood vessels to relax by the production of curing agents, the blood flow increases and the penis is targeting.
But nature also a way for the construction has been designed to disappear. At the same time as mullet, the blood vessels are produced, to relax, the body also produces water softener to break and to neutralize the hardener. This is an enzyme known as phosphodiesterase (PDE5).
While the man is sexually excited plasticizer produced by the hardener penis remains rigid. But once production begins, hardener refuse to rule plasticizers, and the erection begins to fizzle.
It is now generally accepted that SAD is caused by an imbalance of curing agents and plasticizers. The body does not produce enough, or hardener, or too much water softener. In any case, the result of the inability to sustain an erection upright.
What Viagra is the block for the manufacture of plasticizers. This allows the hardening of the arteries in the penis hard and build up, which prolonged erections.
The beauty of this method is that nothing happens without sexual stimulation. Viagra is not the place of stimulation. Instead, we just want the natural chemicals that sexual stimulation from their work. After sex, if not the brains disappear hardener create an erection. And if to bear the effects of Viagra – usually after 4 to 5 hours – the normal processes, the way they were taking the drug restored.
Of course, as with any medication there are possible side effects. Viagra should not be taken if a nitrate-based drug, including nitroglycerin or if your blood pressure or heart medications, such as the combination might result from Viagra with these drugs is a serious decrease in blood pressure. Even if you have liver or kidney problems, it is not recommended that you take Viagra.
