How does Viagra work?

Viagra improves the quality of an erection by boosting blood flow to the penis. This is achieved through the action of the active ingredient sildenafil which works by restricting the chemical phosphodiesterase type-5 in the human body. Even today, increasing number of people prefer to buy Viagra because it is the first medication to work on this principle.

A man achieves an erection through a complex chain of events involving signals received from the nervous system and the release of chemical messengers inside the tissues of the penis. These chemical messengers help blood vessels in the penis relax and widen so as to accommodate better blood flow into the penis. As the blood vessels widen and fill up with blood, they press down on the veins taking blood away from the penis; this restricts blood flow out of the penis. As a result the penis fills up with blood and becomes erect. Buy Viagra as it helps boost the process and extend the time blood is held in the penis.

In erectile dysfunction the blood vessels in the penis are not able to relax fully to accommodate extra blood influx. This in turn does not fully restrict the veins and so the incoming blood finds a way to flow out again and the erection achieved does not last. When you buy Viagra, you sort this problem out as the medication help you maintain an erection long enough to enjoy satisfactory sex. Consult your doctor if you feel you have erectile dysfunction and would like to buy Viagra for treating the same. If you have a valid prescription you can buy Viagra online from 121doc.com.
