A method of treating Peyronie's disease manifested in an erect penis having a first penis side with an unaffected length and a second penis side with an affected length that is shorter than the unaffected length includes attaching an elastic device subcutaneously to the first penis side; and providing the elastic device with a stretch stop that limits elongation of the first penis side to an erection distance that is approximately equal to the affected length of the erect penis.
