Can Exercises Cause or Worsen Peyronie’s?

Short Answer Aggressive manual stretching and jelqing have been linked in clinical literature and society statements to the possibility of tissue injury, scarring, and curvature. Men with known Peyronie’s should seek specialist advice before any exercise or device program.

Detailed Explanation

Peyronie’s disease involves fibrous plaques in the tunica albuginea that can cause curvature, pain, and erectile difficulties. The exact cause is not fully understood, but trauma (including microtrauma) is considered a contributing factor in many cases.

Because jelqing and forceful manual stretching deliberately apply repeated stress to penile tissues, medical sources (including SMSNA-related statements and clinical reviews) caution that these practices may increase risk of injury that could lead to or worsen fibrotic changes.

In contrast, carefully controlled penile traction is sometimes used under medical supervision as part of the management of existing Peyronie’s disease, with a different risk–benefit profile from unsupervised aggressive routines.

Any new curvature, pain, or deformity after an exercise or device session warrants prompt medical evaluation.
