Discovering that your lizard or gecko has a prolapsed hemipenis can be alarming. As a pet parent, it’s natural to feel worried and unsure about what to do next. While this condition can be serious, prompt action and proper care can make all the difference in ensuring your reptile’s health and comfort.

⚠️ What to Watch For

A prolapsed hemipenis occurs when one or both of your reptile’s hemipenes (the paired reproductive organs in male lizards and geckos) fail to retract after mating or other stimulation. This condition is not uncommon but requires immediate attention to prevent complications.

Here are the key signs to look for:

  • A red, swollen, or irritated tissue protruding from the vent (the cloacal opening)
  • Dried or discolored tissue around the exposed area
  • Your pet licking, rubbing, or scratching at the prolapse

Left untreated, a prolapsed hemipenis can lead to tissue damage, infection, or even necrosis (tissue death). Early detection is critical to avoid severe complications.

🔍 Possible Causes

Understanding why a prolapsed hemipenis occurs can help you better care for your reptile and potentially prevent future issues. Common causes include:

  • Mating-related trauma: Prolapse is often triggered during or after mating, especially if the hemipenis becomes stuck or injured.
  • Overstimulation: Excessive handling or stress can sometimes lead to a prolapse.
  • Infections: Bacterial or fungal infections in the cloacal area can irritate the tissue, increasing the risk of prolapse.
  • Dehydration: Insufficient hydration can make tissues less elastic, making it harder for the hemipenis to retract.
  • Underlying health conditions: Parasites, nutritional deficiencies, or systemic illnesses can also contribute to this issue.

Once you notice a prolapse, it’s essential to act quickly to address the underlying cause and prevent further harm.

✅ What You Can Do at Home

While a prolapsed hemipenis is a medical issue that often requires veterinary care, there are a few steps you can take at home to stabilize your reptile until you can consult a vet:

  • Keep the tissue moist: Exposed tissue can dry out quickly, leading to further complications. Use a clean cotton swab or sterile gauze to gently apply a water-based lubricant (like plain, unmedicated petroleum jelly) to keep the area hydrated.
  • Limit handling: Avoid excessive handling or stress, as this can worsen the condition. Place your reptile in a clean, quiet, and warm enclosure.
  • Provide a clean environment: Ensure the enclosure is clean to reduce the risk of infection. Use paper towels or other disposable substrates temporarily for easy cleaning.
  • Soak in lukewarm water: A short soak in lukewarm, shallow water can help soothe irritation and keep the tissue hydrated. Avoid using hot water or adding any chemicals.

These steps are temporary measures. It’s crucial to seek veterinary advice as soon as possible for a thorough evaluation and treatment plan.

💡 When to Call a Vet

If you suspect your lizard or gecko has a prolapsed hemipenis, contacting a veterinarian promptly is essential. This condition won’t resolve on its own and can worsen over time.

Seek immediate veterinary care if:

  • The tissue is discolored, indicating possible necrosis (black or darkened tissue)
  • There are signs of infection, such as pus or a foul odor
  • Your reptile is lethargic, refusing food, or showing other signs of distress
  • The prolapse does not retract after you’ve taken home care measures

A vet may attempt to manually replace the hemipenis or recommend surgical removal if the tissue is damaged beyond repair. Don’t delay—quick intervention can save your reptile from unnecessary pain and complications.

FAQs
