PeniMaster PRO Mode of Operation
The physiological mode of operation of PeniMaster® penis expanders:
Permanent pulling forces stimulate and train the penis. Long-term application causes the formation of new cells within the penis. Amongst others, this allows for penis elongation, thickening, and straightening.
A body part increases in size or changes its shape by means of the formation of new body cells with the tissue. Regarding the male genitals this natural procedure ends at the age of 20 at the latest (upon achievement of sexual maturity). If the penis is to be enlarged or straightened after this age, the penis tissue requires long-term stimulation with the capacity of stimulating further cell growth. For this, PeniMaster PRO subjects the penis to a physical pulling force - which is why these apparatuses are also called "penis expanders" or penis stretchers.
According to our experience the penis can become longer and thicker on the basis of an elongation treatment with PeniMaster PRO covering several months of regular device use, because new body cells grow three-dimensionally in all directions from a physiological point of view if the devices are applied successfully along the plane of traction in particular. Long-term treatment may furthermore compensate reduction in curvatures of the penis. The results of long-term application are likely to be remain post treatment if the stable phase of Peyronie’s Disease has been established.
If the devices are used for short periods of time, temporary elongations of the penis may result from stretching effects.
Furthermore, an elongation treatment may have the same effect on the cavernous body as weight training and may overall penile condition (from a tissue cell-health perspective).

Penis straightening with an expander
A normal (non-pathological) curve in the penis is caused by an uneven number of cells in opposite sides of the penis. The side with fewer body cells ( caused by the formation of more compact scar tissue - see illustration on the left) is shorter, causing a curve in the penis, especially during an erection. By stretching the penis, the side that has fewer body cells experiences more stress, so new cells grow faster on that side than on the side with more body cells. The curve begins to even out (new cells coloured pink).

Cultural changes in the body
Cultural changes in the body through pressure or pulling forces
For thousands of years, humans in various cultures have used pressure or pulling forces to permanently change their bodies. The warrior tribes of Mursi and Surma in southern Ethiopia achieve extensive deformations of soft tissue parts in lips and ears by using permanently attached pieces of jewellery. The jewellery acts like an expander due to its huge dimensions. The famous "Giraffe Women" of Mae Hong Son (Thailand) owe their popularity to extended cervical vertebrae. Their growth is achieved by rings around the neck that are worn permanently and push the head away from the shoulders.
Plastic-cosmetic changes to the body
Plastic-cosmetic changes to the body by means of pressure and pulling forces
The medical field uses both natural and special expanders to correct body parts through mechanical pressure and pulling forces.
An example of the effective use of natural pressure in orthopaedics can be found in the field of paediatric orthopaedics. With the help of an insole, the orthopaedic specialist uses the patient’s weight and pressure on the foot to turn it back into a healthy shape.
