Here, we're going to answer the question: "Do penis enlargement devices work?"

You're in the right place because here we explain the scientific reasons.

In this guide, you're going to learn everything you need to know about extenders:

  • How size is added.

  • What penis traction is.

  • How the penis extender makes all of this possible.

Let's get started.

How Do Penis Extenders Work??

Penis extenders work by utilizing the "traction principle", also known as "penis traction".

What is Penis Traction?

The traction principle invovles keeping a body part in a "stretched" position for long periods of time.

The result?

The body adapts to the tension and experiences Cell Hyperplasia: A growth in body tissue size.

Cell hyperplasia means that the body cells (for us, in the penis) split and double, thus increasing the total number of body cells.

The traction force causes penis cells to divide - resulting in a net increase in penis tissue mass = physical size increase.

The end result is indisputable, permanent size gains due to increased penis tissue mass.

Typical Penis Extender Results

The results reported by the British Journal Urology International (BJUI) was:

.7 inch length gain in 16 weeks.

That's quite a remarkable result given that even the thought of trying to increase your penis size was thought to be a waste of time.

I don't know about you, but if I found out that I could permanently increase my penis size by nearly an inch with practically no safety risk, I would go for it 100%.

But don't take our word for it.

Here are the clinical studies done that contain all the data that back up these results.

In Conclusion

Penis extenders are the perfect tools that will guarantee your penis lengthening success.

They aid you in your penis training by allowing you to stretch for longer without affecting your day-to-day lifestyle.

They have been clinically proven to work and because all men are the same, there's no reason why it shouldn't work for you as well.

We covered the different types of extender systems (pulling and rod-based) how to use them.

We also covered the common things to expect when wearing it.

By applying these points covered in this guide, you'll practically be on your way to getting a larger penis in no time, just as tens of thousands of guys have done before you.
