are medical expanders (extenders) that stretch the penis in a physiologically proper way over a long period of time. This method of tissue stimulation can, for example, be successfully used for the corrective enlargement and straightening of any man’s penis, by people suffering from Peyronie’s disease (IPP) or for penis therapy before and after operations (e.g. removal of the prostate).

Clinical Study 2019: Depending on the application intensity of PeniMaster PRO, the erect penis monthly can gain up to 1 centimeter / 0,4 inches in length and substantially in circumference. In addition, the penis can be significantly straightened.
