How Viagra Professional Works
Viagra was discovered by accident. Originally it was being tested for its ability to cure angina. It didn’t help angina patients, but researchers found a different use for it.
When a man is aroused, his brain produces a chemical that increases blood flow to the penis. It does this by relaxing the muscles that hold the blood flow back and keep the penis in a relaxed state. Once the blood can readily flow, the penis gets erect.
