A penis extender, also known as a penis stretcher, is one of the many non-surgical methods known to man to extend the size of his penis. They are aptly named, as their purpose is to indeed "extend" or "stretch" the penis by applying constant pressure or traction on the delicate organ. The amount of hours spent wearing the device is usually proportionate to the augmentation of the penis.

The roots of traction go back thousands of years to indigenous tribes on the African continent. This remains a common practice among such groups on body parts ranging from lips and ears to necks and arms. Certain penis enlargement companies trust in this time-tested method to permanently expand penises. An effective device allows one to adjust the tension level with metal bars and springs. The distance and traction force should increase as the penis grows.

Bear in mind that all parts should be hypo-allergenic and made from medical grade plastics and metals, or the chances of a rash occurring increases. Penis extenders are one of the most effective ways to enlarge one's penis. It is generally a safe and reliable method if used following proper instructions. Another advantage is that it can be worn under clothing for extended periods of time without any risk of side effects.

Marketed under many names, penis extenders have recently enjoyed a surge due to online companies that promote their brands via websites. It is important, however, to choose a brand that is doctor-approved as this can make all the difference between ordering an authentic penis enlargement tool versus a box of unmanageable and useless spare parts.
