About Viagra

Viagra is a pill used to treat erectile dysfunction (impotence) in men. It can be a great help for many men who have erectile dysfunction in achieving and keeping an erection when they become sexually excited (stimulated).

Just by taking this medicine you will not get an erection. Viagra helps a man with erectile dysfunction get an erection only when he is sexually excited.

Viagra allows many men suffering from erectile dysfunction to respond to sexual stimulation. When a man is sexually excited, Viagra helps the penis fill with enough blood needed to keep an erection. After sex is over, blood flows out the penis and the erection goes away.
