How does Viagra works?

Viagra works in response to sexual stimulation to increase the blood flow to the penis leading to an erection. Viagra does not result in an erection without sexual stimulation. When a man is aroused, muscles in the penis relax to allow this greater blood flow. Viagra helps to elevate the levels of a substance that causes the tissues to relax.

Viagra is a brand name of Sildenafil. There is another medications based on Sildenafil (also called "Viagra-generics") but Viagra is most popular Brand in the World.

It’s been proven to help guys with all degrees of ED. VIAGRA usually starts to work within 30–60 minutes. And you only take it when you need it.

VIAGRA enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection.

Viagra, also known as Sildenafil, does not directly give a man an erection. It works by boosting the natural mechanism that leads to an erection. When a man is sexually aroused, certain tissues in his penis relax. This allows large amounts of blood to flow into the muscle, thus producing an erection. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers.

VIAGRA works only when you are sexually stimulated. You may take it up to 4 hours before sexual activity. So don’t worry. So there's no need to rush. After sex? Your erection should go away. In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.
