Penis stretcher devices or penis extenders are the devices designed to apply continuous stretching force, known as “traction”, to the penis in order to permanently lengthen and enlarge it.

Penis stretcher device applies traction by means of adjustable, calibrated bars between an anatomically curved base that fits comfortably at the root of the penis, and a surgical-grade band that slips off the head of the penis.

As the penis lengthens, the traction and distance can be adjusted. This device is meant to be discreetly worn under the clothes and/or during sleep. Marketed under different names such as SizeGenetics, ProExtender and SizePro System, the device can be obtained from your medical practitioner or online.

How Do Penis Stretcher Devices Work?

As can be seen from the video, the device fits at either end of the penis and creates a gentle expansion by safely applying calibrated, continuous pressure by means of a system of expandable bars.

This stretching opens up spaces between penile cells, and triggers a growth or healing response in the body, in which adjacent cells begin to divide and fill in the space. With continued use, the growth can number in the millions of new cells, significantly adding size and tissue to the penis.
