How Traction Devices Work

Penile traction devices or Extenders/Stretchers work by pulling and causing traction on the penis creating micro tears in the structure which are then healed resulting in a longer penis. The idea of applying traction to these structures to lengthen the penis is a medically sound principle of which several studies have been conducted and found that traction devices can increase the overall size of the penis. Traction therapy has even been used to cure Peyronie's disease and penis curvature.

How To Use

1. Use a pair of comfort sleeves to secure the inner layer of the cup, use the smaller one to cover the inner liner of the cup, with the thicker part stick it into the cup with one end and with the other end wrap it around the shaft of the penis, you may need to insert the penis into the cup before you can get the second comfort sleeve around it
2. Use the adjustment nobs on either side to increase the length, or use the extender rods to the same function.

We recommend you use the extender 2-3 hours a day. If numbness or pain occurs activate the release mechanism and massage the penis to restore proper blood flow and take a break. Studies have shown examples that wearing the stretcher for longer periods of time does increase the total size. It's important to understand that slight discomfort is the only thing that should be felt during this time, outright pain during a stretching session can lead to diminished gains.
