Canadian Family Pharmacy: FAQs about Viagra

Question – Answer

Erectile dysfunction is quite a common problem. Reasons for this are numerous – life full of stress, world population aging. Therefore, the «blue pill» is not a luxury but a great necessity. Canadian Pharmacy Viagra was the first, so most of information was collected about it. A little later, by the same path Levitra and Cialis came to us, and soon their generics. Which pill is the best, and are they really different? Canadian Family Pharmacy suggests «to get the root» and get answers to questions that will help to make a choice.

How does Erection Appear?

According to Aristotle, penis erection occurs as a result of «filling it with wonderful space gas». Some experts of medical history even claim that there were sculptures, showing women with swollen cheeks struggling to fill penises of their beloved with «gas». Well, if seriously, let’s look at human penis structure. It consists of root, body and balanus. The leading role in achieving erection belongs to cavernous bodies. Basis of normal function is blood supply and innervation. Blood flow to cavernous bodies is carried out by paired dorsal arteries. Arteries and nerves are located on each side of center deep penile dorsal vein. Lots of veins, enveloping penis, fall into it. Powerful muscles fix penis root to pelvic bones and anterior abdominal wall.

Arterial blood enters directly cavernous body from paired deep penile arteries and departing from them spiral arterioles (i. e. arteries of small caliber). Role of the latter in penile elasticity occurrence and maintenance is extremely important.

In penis, in rest state, small arteries, that flow into cavernous bodies, are «spasmed» – i. e. narrowed by small muscle fibers tension, which are located in each small-caliber blood vessel. It is due to this compression blood does not flow into penile erectile tissues and it is relaxed. There is an interesting physiological phenomenon – when penis is relaxed, its internal vessels are stretched, and therefore, penis tension (i. e., erection occurrence), occurs only when there is penile blood vessels relaxation and penis is filled with blood. Another important component involved in normal penis firmness maintenance is venous drainage system. In any other area of human body’s veins are vessels that simply carry blood away from the body, taking harmful substances with it. In penis it’s different, because if venous blood just flows out of penis, it would never «get up». Therefore, Mother Nature has invented an amazing device, which scientists named venoblocking mechanism. Its essence is very simple. As through expanded vessels blood flows into cavernous bodies and they increase in size, they press soft delicate veins. Venous blood outflow from penis is «blocked» and appears again only when blood flow to erectile tissues stops (after sexual stimulation cessation) – penis relaxes.

If blood vessels or nerves are involved, in erection development, are functioning incorrectly, a man can not achieve and maintain erection.

How does Impotence Differ from Erectile Dysfunction?

Impotence (from Latin – impotentia – weakness) is absence of penile erection at men, leading to impossibility of performing sexual intercourse. For a long time, «impotence» diagnosis is made to all, without exception, men who have complained on penile erection duration and strength reduction. However, there were patients who had, in fact, erection but its strength was not enough for full sexual intercourse. In other words, these people are not really impotent, but also not completely healthy. Therefore, a new term was proposed – «erectile dysfunction». And today in scientific press the term «impotence» is almost not used. More and more rarely this term is found on pages of popular science literature.

The term «erectile dysfunction» is commonly understood as pathological condition characterized by decrease in erection quality at men and as a consequence – lack of opportunities for performing full sexual intercourse. It turns out that impotence is nothing else, but an extreme form of erectile dysfunction.

How was Impotence Problem Solved Earlier?

At different times, different nations used such exotic methods as powders made from dried penises of some animals, inserting costal cart into penis, erotic creams and ointments, as well as eating raw testicles of young calves. Today there are two groups of treatment methods: conservative (psychotherapy, medications) and surgical. A separate chapter in erectile dysfunction treatment is use of different technical devices. Their basis is suction device. A transparent plastic bulb is put on penis, which through hose connected to compact pump. The pump is pumping air out of bulb, causing increased blood flow to penis and as a result – erection. But this method of treatment in our time is almost not used. Making noise with these bulbs, buzzing pumps before most intimate event in your personal life – it is for you to choose. All of these methods in their effectiveness, accessibility and, above all, security can not be compared with Canadian Pharmacy Viagra pills and its analogs.

How does Viagra Act on Women?

Today, one thing is clear – generic Viagra does not increase sexual desire at women as it does not increase it at men. It could probably help some women with lubricating secretions release, increased excitement and even achieving orgasm, especially in case of diabetes.

When should Viagra be Taken with Caution?

People with cardiovascular system diseases, as well as those who have previously suffered priapism (pathological condition characterized by appearance of erection, which is not connected with erotic stimulation, and can last for long time, causing severe pain in penis). Sometimes after taking Canadian Viagra there occurs rapidly transient change in color perception with blue colors predominance.
