How Penis Pumping Works

The Short Answer

Penis pumping works through the controlled application of vacuum pressure to a penis using a vacuum cylinder and vacuum pump. Vacuum pressure increases penile thickness (or girth) by enlarging the volume of the corpora cavernosa, a spongy tissue that retains blood to produce an erection. Vacuum pressure also lengthens the penis by stretching the suspensory ligament, making it more elastic, and thus allowing the penis to grow longer during an erection.

The Long Answer

Penis pumping produces two distinct types of penile enlargement: temporary gains and permanent gains.

Temporary Gains

First-time and recreational penis pumpers immediately experience an exciting temporary gain called Lymphedema.

Vacuum pressure applied to the penis immediately causes the spongy penile tissue known as the corpus cavernosa to engorge with blood, much as it does during an erection. Continued application of pressure for several minutes causes lymphatic fluid to slowly penetrate deep inside the tissue of the penis, where it becomes trapped. This condition is called Lymphedema, and it is the reason that your penis will be noticeably larger and dramatically heavier after pumping than it is normally during an erection.

While Lymphedema is a temporary condition that will begin to subside after the vacuum pressure is released, the bulk of the lymphatic fluid will take two to three hours to drain from the penis. This time frame can be dramatically lengthened through the application of comfortable pressure at the base of the penis with a cock ring after penis pumping.

Permanent Gains

Permanent penile growth occurs in the form of enlarged length and girth (also called circumference or thickness).

When you apply vacuum pressure with a penis pumping cylinder, you force blood into the penis. Penis pumping will force more blood into the penis than the penis normally contains during an erection. To accomodate the extra volume of blood, the spongy corpus cavernosa tissue expands. Over time, with regular penis pumping, the corpus cavernosa tissue will grow, developing a memory that will allow for a permanent increase in the volume of fluid that the tissue will accept. This persistant ability of the tissue to enlarge to a greater capacity results in enlarged penile girth.

Permanent lengthening of the penis through the use of vacuum pressure occurs when the elasticity of the suspensory ligament is improved through stretching. The suspensory ligament holds the penis to the pubic bone, and although it is resistant to stretching, regular and ongoing vacuum pumping will improve the ligament's elasticity. Significant sustained growth in penile length is much more difficult to achieve than similar gains in girth, but for those with the dedication, sustained growth of one or two inches is typical, and much more significant growth is possible.

Girth versus Length

Most penis pumpers experience more pronounced growth in the girth of their penis than in the length of their penis, and most women find girth to be more important to stimulation than overall length anyway. However, for those interested primarily in lengthening their penis, a vacuum cylinder that fits the girth of the erect penis snugly is best. The tighter fit relative to the sides of the cylinder wall produces more lengthening and stretching of the suspensory ligament, but limits enhancement of girth.

For even more effective lengthening, we offer Penis Enlargement Kits, medically designed for substantial permanent penis length increases, post surgery rehabilitation and penile curvature correction.

The Big Picture

Whether you desire a temporary increase in penis size or permanent gains, it is our experience that most men enjoy both the process and the immediate enlargement from penis pumping. Permanent gains are fantastic for obvious reasons, but will require a disciplined routine similar to an aggressive body building program at a gym.
