But first some background information on penile traction devices ...

A penile traction device is actually a little gadget that you can wear over your penis for gains in length and girth.

How does it work?

The pennis traction device (also known as an extender or stretcher) works on the same principle of traction long used in orthopedic surgery where body cells are "forced" to multiply under a traction force. This addition of new body cells results in the growth or enlargement of the body part as required.

Thus, you may conclude that penile traction devices are based on sound scientific principles and are the only enlargement devices approved by doctors.

In fact, a penile traction device is a mandatory tool for post-surgery treatment - it is indispensible to the patient if he hopes to achieve permanent increases in penis girth and length.

By the way, penile surgery will set you back at least $4,750 if there are no complications involved. The penile traction device, at about 6.3% of this cost, is indeed a smart alternative.

Physically, a pennis traction device is a small tool that you can hold in your hand. It can be worn comfortably under loose clothings like boxers, baggy trousers etc.

How much can you gain by using a penile traction device? It all depends on your usage time and schedule. On average, you should be able to add at least 3.06cm and more 6 months with a good penis extender device.

And as long as you use them according to instructions, these penile traction devices are not known to have any negative side effects on you.
