How Viagra 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.
In many men, especially when they get over 40 years old, a variety of problems can inhibit this blood flow. Stress over a job or financial situation, and poor or inadequate sleep are a couple of examples
Other men have physical reasons for erectile dysfunction. Both poor diet and lack of exercise can affect blood flow, thus making it difficult to get and keep an erection.
With Viagra the solution is simple, increase the chemical and increase the blood flow. Viagra increases the content of this chemical in the blood. In this way, it enhances the natural systems of the body to allow a man to more easily get and keep an erection.
It should be noted that the drug doesn’t create an erection, it just makes it easier to get an erection. Stimulation is still required for a man to get erect.
