The main surgical ask for penis elongation is of men having a penis size within the standard limits but not considered satisfactory by the subject ("small penis"). The aim of this study was to verify the efficacy of the penis-stretching physiotherapy for penis elongation using the Size Genetics extender.
Nine healthy men suffering from "small penis" were enrolled (range age: 26-43 years). The initial stretched penis length was 12.0 cm (range 8.1-15.4). The Size Genetics device was prescribed for at least 6 hours per day, for at least 4 months.
In all subjects the elongation of penis was proportional to the device time of use. After 4 months the stretched penis augmentation was +1.8 cm (range +0.5-+3.1 cm). The daily average use was 6½hours (range 3-9 hours). No side effects occurred.

Our data show the efficacy of the penis-stretching physiotherapy in the "small penis" treatment.
