Clinical reviews and studies indicate that penile traction therapy (stretchers) is effective at restoring and lengthening penile dimensions, particularly in clinical contexts like Peyronie's disease and post-prostatectomy recovery.

The analysis

Papers [1] and [5] specifically discuss the efficacy of penile traction therapy (stretchers) in preserving or gaining penile length (mitigating penile shortening and achieving mean length gains of 1.5-2.3 cm). The remaining papers are either background reviews on general augmentation, surgical techniques, or unrelated conditions.
