The Viagra phenomenon wowed the world with the setting of the last century. For millions of men waiting with anticipation the magic pill could not have come a minute too soon. The pill treats erectile dysfunction or ED, as doctors term male impotence, with the disorder affecting one in every three men who suffer from mild to severe forms of the disease.

These patients have a normal blood supply to the penis but for some reason cannot effect local dilation of the blood vessels, so no erection takes place. The reasons can range from diabetes, hypertension and neurogenic causes (where the nerves are severed) to liver damage and sheer performance anxiety. Sildenafil citrate, as Viagra is scientifically known, acts by inhibiting an enzyme that blocks the blood supply to the penis. This consequently increases the supply and leads to erection.

Viagra was the brainchild of pharmaceutical Pfizer .It was originally invented as a medication for high Blood pressure, but was diverted as a E.D. drug when researchers realized after sample testing that the drug could restore the manhood of all those who were afflicted with E.D.

Drug industry estimates that 30 million American men suffer from some degree erectile dysfunction. Pfizer says 66 % of men with E.D. who have taken Viagra in clinical trials report being able to have sexual intercourse, as compared with 20% who were not given the drug. The pill helps men with E.D. achieve harder erections. They also measured other things like the ability to penetrate a partner, satisfaction with the hardness of the erection and overall sexual satisfaction.

Although Viagra can be purchased only against the production of a medical prescription, it is easily sourceable. You can order online from the numerous websites on the internet. But such purchases is not without its risks. The popularity of the drug has lead to spurious Viagra being sold in the market.

The wonderdrug however, like all chemically produced drugs is not free from sideeffects. The most common side effects of VIAGRA are headache, facial flushing, and upset stomach. But then its a small price to pay for a rejuvenated sexlife.
