A Peyronies treatment device is described that is configured to treat an erect penis having curvature characterized by a first penis side with an unaffected length and a second penis side with an affected length that is shorter than the unaffected length. The device includes a band connected between a proximal support that is attachable to a base of a penis and a distal support that is attachable adjacent a corona of the penis. The band has an elastic material and a second material that is attached to the elastic material. The second material is provided to stop elongation of the elastic material at a length approximately equal to the affected length of the erect penis.
