How To Tell If A Leopard Gecko Is Pregnant

Table of Contents

Leopard geckos are popular pet reptiles, and many owners are interested in knowing if their female gecko is pregnant. However, determining the pregnancy of a leopard gecko can be challenging because these reptiles do not show obvious signs of pregnancy, and it can be difficult to tell if they are carrying eggs or not. 


In this article, we will discuss some of the ways to tell if a leopard gecko is pregnant so that you can be sure your pet is in good health. Whether you are a seasoned gecko owner or just starting out, this guide will help you understand the signs of pregnancy in leopard geckos, and provide you with the information you need to keep your pet healthy and happy.


Physical Changes

There are several physical changes that can indicate a leopard gecko is pregnant:


  • Enlarged belly: A pregnant leopard gecko’s belly will become larger and rounder as the eggs inside her grow.
  • Fat storage: Pregnant geckos will often store fat in their tails, giving it a bulkier appearance.
  • Softening of the belly: As the eggs grow, the belly will become softer and more pliable.
  • Behavior changes: Pregnant geckos may become less active and more docile.


It’s important to note that not all of these physical changes may be present in every pregnant leopard gecko, and some may not show any noticeable signs at all. If you suspect your leopard gecko may be pregnant, it’s best to consult with a veterinarian for a definitive diagnosis.


Observing Oviposition

Leopard geckos are oviparous, meaning they lay eggs rather than giving live birth. Here are the steps you can take to determine if your leopard gecko is pregnant:


  • Observe the belly: A female leopard gecko that is gravid (pregnant) will have a slightly round belly that is noticeably heavier than normal.
  • Check for gravid spots: Pregnant female leopard geckos will develop gravid spots, which are small, dark dots on their belly that are a sign of the eggs growing inside.
  • Watch for oviposition: Oviposition is the process of laying eggs. It usually occurs about 3-5 weeks after mating and can be seen as a female leopard gecko digging a hole or searching for a suitable place to lay her eggs.
  • Inspect the eggs: After oviposition, the eggs will be visible in the hole. They will be about the size of a grape and have a hard, leathery shell. If the eggs are fertile, they will contain a developing embryo.


It is important to note that not all female leopard geckos will lay eggs even if they are sexually mature. If you are unsure if your leopard gecko is pregnant, it is best to consult with a veterinarian.


Testing For Pregnancy

Leopard geckos can be tested for pregnancy in several ways:


  • Physical examination: A veterinarian can perform a physical examination on the female leopard gecko and look for physical changes such as an enlarged belly and changes in her behavior or appetite.


  • Radiography: X-rays can be taken of the female leopard gecko to confirm pregnancy and check the number of eggs in the oviduct.


  • Ultrasound: An ultrasound can also be performed to confirm pregnancy and monitor the development of the eggs.


  • Egg production: Female leopard geckos usually lay eggs within 2-3 weeks of mating. If she has laid eggs within this time frame, it is a good indication that she is pregnant.


It is important to note that not all female leopard geckos will show physical signs of pregnancy and some may lay infertile eggs even if they have mated. The best way to determine pregnancy in leopard geckos is to have a veterinarian perform a physical examination and/or radiography or ultrasound.



In conclusion, to determine if a leopard gecko is pregnant, observe its behavior and physical appearance. Check for the presence of eggs or a bulge in the abdomen, increased appetite, and changes in skin texture. If you are unsure, a vet can perform a blood test or ultrasound to confirm pregnancy. It is important to provide adequate care and nutrition for a pregnant gecko to ensure a healthy birth.
