The worst nightmare of every man is to discover that at the height of the most passionate moment he does not have an erection. But they are lucky, because we live in the XXI century, and medical research began to bear results. Today, if you suffer from erectile dysfunction, at your disposal there are different methods of treatment – from the complex treatment of impotence to effective short-acting drugs. Viagra is the most famous of them, but My Canadian Pharmacy will talk about it later.
How does Erection Work?
Erection, in general sense, is a change in the condition and size of the penis. To provide it, several parts of the human body must work. The brain sends a message of sexual excitement through the nervous system to the penis. This message causes the muscles of the penis to relax. At the same time, the artery that supplies blood to this organ expands twofold and thereby significantly increases the flow of blood, and veins that divert blood from the penis are blocked. As a result, two cavities of spongy tissue inside the penis are filled with blood, and it becomes hard. Violation of any component of this system makes appearance and maintenance of erection difficult.
For a full understanding, let’s look at the mechanism of erection in more detail. As already mentioned, inside the penis along the entire length of the body there are two cavities, which are called cavernous bodies. They are filled with spongy tissue. The cavities are surrounded by a membrane, called albugineous coat. In cavernous bodies, there is a smooth musculature, fibrous tissue, veins, and an artery. Urethra – the channel through which urine is excreted and discharge of seminal fluid is released – is located on the inner sides of cavernous bodies.
Erection begins with sensory and mental stimulation. Impulses from the brain and local nerve endings cause cavernous bodies to relax through the release of certain chemicals. Thus, they let blood in and increase the volume of the penis. Filling hollow spaces inside the penis, blood creates pressure, which, in fact, increases size. Albugineous coat under pressure blocks the outflow of blood and thereby restrains erection. And when muscles of penis contract, the flow of blood stops, and discharge channels of blood are released. Erection cancellation is also provoked by the release of chemical substance phosphodiesterase-5.
Erection in a healthy man occurs several times a night during «fast sleep». Everyone knows such a phenomenon as «morning erection». It is also called «unprovoked erection». This is a very good sign – all your mechanisms work as they should.
Viagra for Steady Erection
If erection can not be caused even arbitrarily, you need help. Viagra is one of the most famous and popular drugs in our time. This is often used by scammers. There are so many advertisements for this miracle drug on the Internet that the manufacturer of Viagra had to take action. The company has created a special page on its website to warn its customers against fakes.
Viagra works simply – it provides erection with sexual stimulation. But how does it do it? And why does it work only when a man has sufficient stimulation? And what exactly is the cause of erection with use of medicine?
Viagra simply blocks phosphodiesterase-5. Then those substances that are responsible for erection, remain inside the penis, so that muscles of the penis do not contract, and blood lingers inside longer, and this is what allows a man to maintain an erection.
Does Viagra work without stimulation? Many men are interested in this issue. But the answer is negative because substances that cause erection must somehow get inside the penis. These substances are released only when a man is excited. Viagra itself does not release these components. It only helps to keep them inside the body for a longer time.
Many more men are interested in how long it takes to wait for Viagra to act. There is no definite answer. It depends on your body. In clinical studies, Viagra started working only 14 minutes later. But most representatives of the stronger sex will have to wait 30 minutes. In most cases, the effect of the drug can be seen after that another four hours, but it also happens that after two hours action is completely gone.
Erectile dysfunction, which is more often called impotence, happens to men of different ages. That’s why Viagra is so popular. Before taking the drug, be sure to consult your doctor. Canadian Pharmacy warns that like any other medication, Viagra can cause side effects. But if used correctly, it is very effective and harmless.
