The JES Extender uses traction to assist the human body`s natural ability to change and develop under physical influence.

If a certain part of the body is exposed to a constant, permanent stretch, the cells in this area begin to divide and multiply, thus increasing the tissue mass. This natural principle has been known and used through centuries in many different cultures in order to develop or extend various body parts.
The same principle has also been used in surgery to lengthen fingers or legs and also to cover tissue defects in the face.

The JES Extender applies constant traction, which should be gradually increased over the first few weeks, until the correct tension is achieved.

Treatment with the JES Extender has no side effects and no influence on either urination, erection or fertility.
