The Technology Of Erection
By: Robert Stalling


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
