It is a device with medical certification that is used to lengthen the penis through traction. How does JES-EXTENDER work? JES-EXTENDER is easy to apply, does not cause pain and is undetectable under baggy pants. The JES-EXTENDER increases both the length and girth of the penis. It is the only proven and documented method of penis enlargement without surgery or doctor consultations. The beginningJES-EXTENDER uses traction to guide the natural ability of the human body to change and develop under physical influence. If you expose a certain part of your body to constant stretching, the cells in this area begin to divide and multiply, thereby increasing tissue mass. Consequently, elongation occurs in both the length and width (thickness) of the penis. Various and numerous different cultures know and have used this natural principle throughout the centuries to develop or lengthen various parts of the body.medical deviceA specially designed plastic ring is placed around the base of the penis. A plastic and silicone clip fits around the head of the penis. Between the ring and the fastener, two dynamic metal bars apply a tension ranging between 600 and 1,500 grams. The user regulates the tension. The JES-EXTENDER adapts to all people and penises of any size. How does it work in practice? The JES-EXTENDER can be used at any time of the day for extended periods, at work or in your free time, depending on your activities. The total number of hours of use of the JES-EXTENDER and the traction applied determine the result of the treatment. It is not necessary to use the JES-EXTENDER for a long, uninterrupted period to obtain results. Example: a treatment of 2 hours a day for 12 months will give the same final result as a treatment of 12 hours a day for 2 months. You can also stop using it for a while without affecting the final result. This does not mean you will "lose" part of the results obtained. It can also be used at night, although it may come loose if you move while sleeping or during a nocturnal erection. It is recommended to use the Protective Pad or any other protective measure for night use of the JES-EXTENDER. After some practice, applying the JES-EXTENDER will take less than a minute. Treatment with JES-EXTENDER has no side effects, it does not affect urination, erection or fertility and the lengthening is permanent. You don't need your doctor's help. In the field of surgery, the same principle has been applied to stretch fingers or legs and to cover defects on the face. Permanent results of 3 to 5 centimeters.
