Our entire line of medical male enhancement and penile augmentation devices must be used with the penis in a flaccid state. Depending on the model, the devices can be used between 4 or 9 hours per day, taking a break when needed. Each model applies the principle of traction but in different ways.
While using Andropeyronie, the patient can control the direction of the traction in order to apply stronger force to the opposite side of the curvature. This will help the penis to straighten by up to 50%. (PubMed)
