How does sex affect your body ? When a man is sexually excited, the penis rapidly fills with more blood than usual. The penis then expands and hardens. This is called an erection. After the man is done having sex, this extra blood flows out of the penis into the body and the erection goes away. What is Viagra ® and how does it help ? Viagra ® is a pill used to treat erectile dysfunction (impotence) in men. It was originally developed as a heart medication to improve blood flow by relaxing the arteries. During these studies, it was found Viagra ® to be effective in increasing blood flow to the male genitals. Increased blood flow will allow men, who in the past were diagnosed as sexually dysfunctional or impotent, to perform normally for up to 6 hours after taking it. It was approved by the FDA on March 27th, 1998. It has been estimated that about 30 million men in the US alone suffer from erectile dysfunction. Traditional treatments which include suppositories, injections, penile implants and other procedures, many of which are painful and embarrassing were followed. Viagra ® manufactured by Pfizer is a revolutionary medication that has been shown to help about 70% of men with impotence problems. What Viagra ® does not do ?
