Mainly this problem of ED is visible after the age of 60 but in many cases it can occur much before than expected. ED is normally caused when the blood flow to penile region is reduced due to some physical injury. It may also because of bad lifestyle, as a result of some mental or emotional stress, some kind of alcohol or drug addiction etc.

It was the overall change in the scenario and in the lives of men suffering from erectile dysfunction when viagra, scientifically called sildenafil was launched in market. This is the case of March 1998 when viagra was launched. It increases the physical ability to achieve and maintain erection for sexual relief.

When the man is sexually excited, the arteries of penis relax and widen allowing more blood to flow in to the penis resulting in the hardened and erected penis and the same time veins that carry blood out of the penis get compressed restricting the blood to flow out of the penis. When any of these processes aren?t working properly because of some physical or mental stress, viagra comes into action. It increases the blood flow to the penis. The success rate of this pill is more than 80 percent. But this should be kept in mind that viagra is not a hormone or aphrodisiac.
