The Technology Of Erection
There are a variety
of erection drugs currently on the market. It is
essential that you check with your doctor before using any of
these drugs. Although they can be beneficial they can
have serious side effects. Viagra ®, Cialis ®, and
several other choices are available once you contact your
physician.

When you want to move nearly any part of your body, you do
it using muscles. Whether you are moving your fingers, toes,
arms or legs, muscles do the work. Even when you stick your
tongue out, you do it using muscles:
1> You think about moving some part of your body
2> The appropriate muscles contract
3> That part of the body moves
Muscles let you move your body voluntarily with precise
control.

The penis, on the other hand, is completely different. There
are no muscle contractions involved in making the penis erect.
To become erect, the penis instead uses pressure.
Probably the easiest way to understand how the penis becomes
erect is to think about a balloon. If a balloon has no air in
it, it is limp. As you inflate a limp balloon with just a
little air, it becomes elongated and rigid.
The penis uses a similar mechanism, but instead of using
pressurized air to become rigid, the penis uses pressurized
blood. The penis contains two cigar-shaped structures, called
corpus cavernosa (singular - corpus cavernosum), that it uses
to become erect.
Think of the corpus cavernosa as balloon-like tubes. Arteries
bring blood into these two tubes, and veins carry blood away
from them. The penis can be either limp or erect, depending on
the flow of blood:
1> In a non-erect state, the arteries that bring blood into
the corpus cavernosa are somewhat constricted, while the veins
that drain the blood from the penis are open. There is no way
for pressure to build inside the penis. In this state, the
penis is limp.
2> When a man becomes aroused, the arteries leading into the
penis open up so that pressurized blood can enter the penis
quickly. The veins leaving the penis constrict. Pressurized
blood is trapped in the corpus cavernosa, and this blood causes
the penis to elongate and stiffen. The penis is erect.
If the arteries leading to the penis do not open up properly,
it is difficult or impossible for a man to become erect. This
problem is the leading cause of erectile dysfunction.
To solve an erection problem when the cause is poor blood flow,
you need to open the arteries and this can be done using
Viagra
