The anatomy of the penis is complex. It is comprised primarily of two cylinders of sponge-like vascular tissue that fill with blood to create an erection. Blood is pumped into the penis under great pressure and a series of valves keep it in the penis to maintain the erection.

A third cylinder is the urethra, a tube that carries the urine and the ejaculate. The knobby head of the penis is called the glans. Blood flows to the penis by two very small arteries that come from the Aorta. These arteries are the same size as the arteries to your finger. The main problem that causes impotence is that the blood vessels become blocked and the blood can not get to the penis.

An erection occurs when during sexual arousal the nervous system activates a rapid increase in blood flow. The vascular muscle in the spongy area becomes engorged with blood and the outflow of blood is cut off. An erection can occur as a reflex as we see in spinal cord patients, or can be caused by psychogenic (originating in the mind) stimulation. Numerous sexual stimuli are processed by the brain and transmitted to the penis via the nervous system.

In order to increase the size of an erection, there must be an increase in blood flow and, at the same time,  the blood has to be prevented from leaving the penis.

Kinsey and associates collected data concerning penis size from 3.500 adult males. All lenght measurments were taken when the penises were erect, along the top of the penis, from the point where the top of the penile shaft meets the pubic area to the tip.

The foreskin was retracted in circumcised men. All girth measurments were taken from around the middle of the penis. Later data published included flaccid penis lenght. Kinsey found out that the average penis lenght is 6,36 inches, and the average girth is 4,94 inches.

Does penis size matter to women? In a poll conducted by Durex condoms, 67% of women said that they are unhappy with their lover’s penis size. In other words, two out of three girls prefer bigger penis.

That survey also revealed that 93% of women have never achieved orgasm during intercourse and 76% admit that they are dissatisfied with their partner’s sexual performance.

ProSize is a powerful blood flow promoter that increases blood flow to the erectile chambers of your penis during arousal (erect state). Over time, the increase in both the amount and force of blood flow may cause the erectile chambers to expand, thereby creating a larger, fuller erection with extended pleasure. Some of the ingredients in ProSize act as an aphrodisiac, increasing your sexual desire and therefore hightening nerve stimuli from your brain which also play crucial role in erection.

If  ProSize penile exercises are combined together with pills, over several months one can experience gains in penis size up to 20%!
