It has been estimated that about 30 million men in the
USA 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 shorn to help about 70% of men with impotence
problems.
Viagra® improves a man's response to sexual stimulation.
To understand how, you need to understand how an erection
happens in the first place.
Erections are all about increasing blood flow to the
penis. Without sexual stimulation, the body limits blood
flow into the penis. This keeps the penis flaccid (soft
or not erect). |

When a man is sexually aroused, the arteries in the
penis relax and widen, allowing more blood to flow into
the penis. As the penis expands and hardens, veins that
normally carry blood away from the penis become compressed.
This restricts how much blood can flow out of the penis.
With more blood flowing in and less flowing out, the
penis enlarges, resulting in an erection.
If the nerves or blood vessels associated with this
process aren't working properly, a man may not be able
to get an erection.
Viagra® increases blood flow to the penis, so that
when a man is sexually aroused, he can have an erection.
When the sexual encounter is over, his erection goes
away.
If a man takes Viagra® and then circumstances change
and he isn't sexually stimulated, he won't get an erection.
You won't get an erection just by taking the pill.
Viagra® is not a hormone. Viagra® is not an
aphrodisiac. It is a prescription medicine that can
improve the erectile function of many men with erection
problems.
