Penile Prolapse

What is it?

Penile prolapse (paraphimosis) means a male glider's penis stays outside the body and can't go back in. The exposed tissue dries out and swells, and gliders often chew it. Causes include infection, trauma, bedding fibers wrapped around the tissue, and stress or excess sexual behavior.

What signs should I watch for?

Signs to watch for include pink or dark swollen tissue near the cloaca, licking or chewing the area, bleeding, difficulty urinating, and hiding or reduced appetite.

How is it diagnosed and treated?

This should be seen promptly. Your veterinarian cleans the tissue and tries to replace it, often under sedation, while treating swelling, infection, and pain. If tissue is badly damaged, surgical amputation of the penis may be needed; males still urinate normally afterward because the urethra is separate.

Can it be prevented, and what's the outlook?

  • Avoid loose, stringy fabric bedding, keep the cage clean, and watch for licking at the genitals.
  • Neutering may be discussed for some males.
