How Viagra works?
Viagra enables lots of men with Cessity to react to sexual stimulation. When a man is sexually aroused, the arteries within the penis relax and widen, allowing more blood to circulate in to the penis. Because the arteries within the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood circulation out of the penis. With more blood flowing in and less flowing out, your penis enlarges, resulting in a harder erection. It is to be noted that Viagra is not a hormone or aphrodisiac, it really works only when a man is sexually stimulated.
