Can a condom that is too tight, which was left on while asleep cause an hourglass deformity? Could this hourglass shape be the beginning of PD?

Dr. Levine answers: It is unlikely that the condom itself could trigger PD, but if during sexual activity there was trauma to the penis this is the more likely cause. Hourglass deformity is not typically an early onset type of deformity associated with Peyronie’s disease. Usually there would be a small localized indentation which may progress to an hourglass deformity over time. In general, application of constriction bands, rubber bands, cock rings, are unlikely to activate the Peyronie’s process by themselves particularly in the flaccid state.
