How Does Penis Traction Work?

Technically the device is a penis stretcher, but understanding how penile traction works isn’t as simple as saying “it stretches the penis.”

There’s a lot of scientific data to back up this product, and we’re going to do our best to explain how this product works fundamentally.

The Science Of Penis Traction Explained

how to use a penis extenderIf you’ve ever been to the gym or have even basic knowledge of how lifting weight helps build muscle, you have a good foundation to understand how the product works.

With weight training, the weight lifter’s hands grasp a dumbbell, his fingers clench the bar, he tenses his back keeping it erect and curls the weight using his bicep muscles.

He slowly lowers the weight back down and repeats the exercise in hopes of building muscle.

The clanking of the weights doesn’t build muscle nor does the iron that the weight is made of.

Small micro tears and cell duplication causes the muscles to grow.

Muscles, when put under pressure, develop small micro tears that strengthen and grow when healed.

Penis stretching works much in the same way.

how do penis extenders work

And no, you’re not going to be using a weight to make your penis grow although some people do use weights for penis growth.

The medical grade extender attaches to the penis in order to do one thing:

  • Supply a constant, gentle stretch to the Corpora Cavernosa

The Corpora Cavernosa is erectile tissue that makes up the bulk of the penis. This tissue is akin to a sponge, and when the penis gets erect, this tissue holds the most blood causing the erection.

Gentle, painless and constant pressure on the penis causes the cells to pull away and split.

Corpora Cavernosa

And these cells will heal causing new cells to be created at the same time. This is the same concept as the bodybuilder lifting weight to sculpt his biceps. See, the body deals with tears by healing them to ensure they’re stronger and better prepared for new stress.

The body heals the penis in the same way.

New cells lead to a bigger penis. The Corpora Cavernosa tissue heals and more cells are created. The healing allows the tissue to be larger allowing for more blood to fill the tissue. Bigger and harder erections are the result of more blood filling the Corpora Cavernosa.

This penis extender doesn’t use weights to achieve these small micro tears (don’t worry, you don’t feel the actual tears).

Traction tension is used to cause the tears and initiate the healing and cell duplication process. SizeGenetics utilizes 2,800 grams of traction tension to provide results faster than any other device on the market.

Real World Before & After Results

And, this traction device can work for two very concerning penile conditions.

#1) Peyronies Disease (Curved Penis Syndrome)

bent penis syndrome

That first is known as Peyronies Disease, this condition is a curvature of the penis which causes:

  • Pain
  • Lack of confidence
  • Low self-esteem

And a person suffering from Peyronies will also have a smaller looking penis.

The SizeGenetics extender is classified as a medical 1 type device. Through continual stretching of the penis, customers have successfully straightened their curved penis.

#2) Micro Penis Syndrome

Micro penis is an interesting condition where a person has a very small penis of under one-inch in some cases.

To be clear, a micro penis can sometimes benefit from SizeGenetics, but not always.

The company recommends that anyone suffering with a micro penis call their customer service team to see if the product can help.  You want to make sure the product will work for you before committing to a routine.

Multi-Directional Angling

You won’t see many people talking about multi-directional angling technology, but it’s vital to the way our device works. See, most devices use just one angle when stretching the penis. This one angle design causes discomfort and hinders growth.

But when multi-directional angling is used, penis stretching is more comfortable.

Results are amplified, too.
