Penis Enhancement based on stretching consists of attaching a penis stretcher or extender device to the penis for set periods of time. The device exerts a constant traction on the penis, which lengthens and widens the penis. The traction causes the cells in the penis to "split" and then reform and expand.

Andropenis is a penis enhancement device which employs the medical principle of traction to stimulate healthy growth of the corpus cavernosum and the rest of the penile tissues.

This penis enhancement occurs due to the reactive capacity of tissues to undergo cellular multiplication when they are subjected to a continuous traction force. Because it works with the body's natural ability to adapt to traction, it is a safe penis enhancement method.

Traction is also used in modern medicine, such as in plastic surgery, for the purpose of tissue expansion. The regeneration of new tissue through traction is used to cover skin defects, burns and hair loss areas. It is also used in orthopedic surgeries to enlarge the diaphysis of bones and phalanges

  The growth is natural and lasting the penis enlargement results are permanent.
