What is Generic Viagra?

How does Generic Viagra work?
Generic Viagra enables men with ED to respond to sexual stimulation. When a man is sexually excited, the arteries in his penis relax and widen. This allows more blood to flow into the penis. The increased blood flow causes the penis to become hard and erect. The veins that normally carry blood away from the penis then become compressed. This restricts the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection. Sometimes the nerves or blood vessels that are part of this process don't work properly. If this happens, a man may not be able to get or keep an erection. Generic Viagra increases blood flow to the penis, so that when a man is sexually excited, he can consistently get and keep an erection. When he is done having sex, the erection goes away.
