Penis Anatomy

One of the most frequently asked questions when it comes to penis enlargement is simply ‘how does it work?' How is it possible to increase the size of your penis by simply popping a pill?

Well, that's a reasonable question. Much of the information you find on the Internet will tout penis enlargement pills as nothing short of magic beans. However, since doctors don't pull rabbits from hats and magicians don't perform surgery it's probably a good idea to take the mysticism out of the subject and apply a little science.

Here we'll see exactly how the penis functions: what causes an erection, and how it is possible to increase its erect size.

Anatomy of the penis

How is an erection caused?

An erection occurs when the Corpora Cavernosa – two spongy bodies that run the length of the penile shaft – become engorged with venous blood. Sexual arousal triggers vaso-dilation in the arteries that supply blood to the penis, causing a greater volume of blood to flow into the organ.

Is it that simple?

Well, not really. The above explanation makes it sound as if an erection can be switched on and off like a light switch, but in fact there are many complex processes, both physical and psychological, that must occur in order to cause penile erection – though it isn't necessary to go into the details for our purposes.

All we need to know about the penis is this simple fact – the greater the volume of blood the penis can hold, the larger an erection will be. This is where penis enlargement techniques come into play.

The various techniques of penis enlargement help to increase the maximum capacity of the Corpora Cavernosa, allowing more blood to flow into the penis upon sexual arousal. While mechanical techniques aim to stretch the Corpora Cavernosa themselves, medical techniques (such as pills and patches) target the densely packed mass of blood vessels that fill the Corpora Cavernosa.

So it is simple?

Yes, I suppose it is. By improving the condition of the blood vessels in and around the genitals it is possible to increase the erect size of the penis. Penis enlargement pills may not be magic beans, but when you apply a little science you can see how they make the penis grow like a beanstalk.
