Common Breeding Problems In Leopard Geckos

Table of Contents

Leopard geckos are popular pets among reptile enthusiasts due to their unique appearance and relatively easy care requirements. However, like any living creature, they can encounter health problems and breeding issues. While breeding leopard geckos may seem like a simple task, it can be complicated and time-consuming, especially for inexperienced owners. In this article, we will discuss some of the most common breeding problems in leopard geckos and how to prevent or address them. By understanding these issues, you can provide the best possible care for your leopard geckos and ensure a successful breeding experience.



Infertility in leopard geckos is a common breeding problem that can occur due to a variety of factors. Here are some of the possible causes of infertility in leopard geckos:

  1. Age: Leopard geckos may not reach sexual maturity until they are around 8 to 12 months old. If they are bred before they reach sexual maturity, they may be infertile.
  2. Poor nutrition: Leopard geckos require a balanced diet that includes a variety of insects, such as crickets, mealworms, and waxworms. If they are not getting enough nutrition, they may be infertile.
  3. Inbreeding: Inbreeding can lead to reduced fertility and the production of infertile eggs.
  4. Stress: Leopard geckos can become stressed if they are housed in overcrowded conditions or if their environment is not suitable. This can lead to infertility.
  5. Temperature: Leopard geckos require specific temperature and humidity levels for optimal breeding conditions. If the temperature is too low, it can affect their ability to produce fertile eggs.
  6. Health problems: Leopard geckos that have health problems may be infertile. Common health problems include parasitic infections, respiratory infections, and metabolic bone disease.


Egg Binding

Egg binding is a common breeding problem in leopard geckos that occurs when a female gecko is unable to lay her eggs. This condition can be very serious and potentially life-threatening if not addressed promptly.

The most common cause of egg binding in leopard geckos is improper husbandry. Inadequate temperatures or humidity levels in the gecko’s enclosure can lead to dehydration, which can cause the eggs to become stuck inside the female. Additionally, a lack of appropriate nesting sites or substrate can also contribute to this problem.

Symptoms of egg binding may include a lack of appetite, lethargy, and a visibly swollen abdomen. In severe cases, the gecko may appear to be in pain or distress. If you suspect that your leopard gecko is experiencing egg binding, it is important to seek veterinary care immediately.

Treatment for egg binding may involve gentle massage of the abdomen to help stimulate the gecko to pass the eggs. In some cases, medication may be prescribed to help relax the muscles of the reproductive tract. Surgery may be necessary in extreme cases where the eggs are impacted and cannot be passed naturally.

Preventing egg binding in leopard geckos involves maintaining proper husbandry and providing appropriate nesting sites and substrate. It is important to ensure that your gecko has access to a moist hide box to aid in shedding and egg laying. Additionally, providing a lay box with moist substrate can help encourage your gecko to lay her eggs.


Mating Injuries

Mating injuries are a common breeding problem in leopard geckos. Male leopard geckos have hemipenes, which are two penile bulges located at the base of the tail, and during mating, they insert one or both of these into the female’s cloaca. If the male is too rough during this process, or if the female is not receptive to mating, she may resist and injure the male’s hemipenes. This can lead to serious injury and infection, and may even require surgical intervention. To prevent mating injuries, it is important to ensure that both the male and female are in good health and receptive to breeding, and to provide a suitable mating environment with plenty of hiding places and a shallow dish of water for the female to soak in.



Overbreeding is a common breeding problem in leopard geckos that can have negative consequences for both the adult geckos and their offspring. Overbreeding occurs when geckos are bred too frequently or are not given sufficient time to recover between breeding cycles. This can lead to a range of health issues, including malnourishment, weight loss, and reproductive problems such as egg binding. Overbreeding can also result in poor-quality eggs and hatchlings, as the adult geckos may not have enough energy or nutrients to produce healthy offspring. To prevent overbreeding, it is important to give leopard geckos adequate time to recover between breeding cycles and to ensure that they are provided with a healthy and nutritious diet.



Inbreeding is a common breeding problem in leopard geckos that can lead to a range of negative health outcomes. When individuals that are closely related are bred together, it can increase the chances of genetic disorders, reduced fertility, and weakened immune systems. Inbreeding depression can also lead to smaller clutch sizes, shorter lifespans, and decreased growth rates in offspring. To avoid these problems, it is important for breeders to maintain genetic diversity by avoiding mating closely related individuals and incorporating new bloodlines into their breeding programs.


Temperature Fluctuations

One of the most common breeding problems in leopard geckos is temperature fluctuations. Leopard geckos require specific temperatures to maintain their health and reproductive success, and even small fluctuations can have negative impacts on their breeding behavior. Temperature fluctuations can lead to stress, decreased appetite, and reduced reproductive activity. It is essential to maintain a consistent temperature in the breeding enclosure to ensure successful breeding and healthy offspring. Using a high-quality thermometer and heating equipment and regularly monitoring the temperature can help prevent temperature fluctuations.



In conclusion, breeding leopard geckos can be a rewarding and exciting activity. However, it is important to be aware of the potential problems that can arise and take steps to avoid them. By maintaining proper husbandry and monitoring your geckos’ health and behavior, you can help ensure a successful breeding experience.
