How Does It Work?

Viagra makes the blood vessels relax so that blood could easily flow to the penis.

This way the male organ stays erected and hard long, which is enough to have sex. It is important to say that Viagra works only if a man is sexually aroused. It is the brain that makes the nervous system release certain chemical compounds that relax the muscles in the penis and Viagra only helps to maintain in it on a high level.

The studies show that Viagra is a very effective treatment compared to placebo. It helps men to have erection in 80% of cases, whereas men on placebo had erection only in 50% of cases.
