How Viagra works?

Viagra enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and expand, 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 pressurized, setting the the circulation of blood out of the penis. And with blood flowing in and less flowing out, the penis grows larger, resulting in an penile erection. It is to be noted that Viagra is not a hormone or aphrodisiac, it works only when a man is sexually stimulated.
