Do Crested Geckos Lay Eggs Without Mating?

Crested geckos are fascinating creatures that make wonderful pets. They are easy to care for and have a unique appearance that sets them apart from other reptiles. One question that many people ask about crested geckos is whether or not they can lay eggs without mating. In this article, we will explore this question in depth and provide you with all the information you need to know about crested geckos and their reproduction.

Understanding Crested Gecko Reproduction

Crested geckos are oviparous, which means they lay eggs. Unlike some other reptiles, crested geckos do not give live birth. In the wild, crested geckos mate during the breeding season, which typically occurs in the spring and summer months. During mating, the male crested gecko will deposit sperm into the female’s cloaca, which is the opening where both waste and eggs are expelled.

Once fertilized, the female crested gecko will lay a clutch of eggs within two to three weeks. The number of eggs in a clutch can vary, with most females laying between two to eight eggs. The eggs are typically laid in a warm, humid location, such as beneath leaf litter or in a tree hollow. After laying her eggs, the female will not provide any further care for them.

Can Crested Geckos Lay Eggs Without Mating?

While crested geckos do require mating to produce fertile eggs, it is possible for them to lay infertile eggs without mating. This process is called parthenogenesis, and it occurs when an egg is fertilized by the female’s own genetic material, rather than by sperm from a male.

Parthenogenesis is relatively rare in crested geckos, but it has been observed in captivity. In some cases, female crested geckos may lay eggs that appear to be fertile, but the resulting offspring will be genetic clones of the mother. These offspring will be female, as they do not receive genetic material from a male.

It is important to note that while parthenogenesis can occur in crested geckos, it is not a reliable method of reproduction. The resulting offspring are often weaker and less healthy than those produced through mating with a male.

Benefits of Crested Gecko Reproduction

Breeding crested geckos can be a rewarding experience for experienced reptile keepers. With proper care, crested geckos can produce healthy offspring that can be sold or kept as pets. Breeding can also help to preserve certain genetic traits or color morphs that are unique to a particular individual or breeding pair.

However, it is important to note that breeding should only be undertaken by experienced reptile keepers who are knowledgeable about crested gecko care and reproduction. Breeding can be stressful for the animals involved, and it is important to ensure that they are healthy and well-cared for throughout the process.

The Risks of Breeding Crested Geckos

Breeding crested geckos can also come with risks. Female crested geckos can become egg-bound, which means that they are unable to pass their eggs. This can be a life-threatening condition that requires immediate veterinary attention.

Breeding can also result in injuries to the animals involved, particularly if they are housed together for an extended period of time. It is important to monitor your crested geckos closely during the breeding process and separate them if any signs of aggression or stress are observed.

Caring for Crested Gecko Eggs

If you do decide to breed your crested geckos, it is important to provide proper care for their eggs. The eggs should be incubated at a temperature of around 78 to 82 degrees Fahrenheit and a relative humidity of around 80 to 90 percent.

Eggs that are not properly incubated may fail to hatch or may produce weak, unhealthy hatchlings. It is important to monitor the temperature and humidity of the incubation environment closely and make adjustments as needed.

Crested Gecko Breeding Versus Adoption

While breeding crested geckos can be a rewarding experience, it is important to consider the pros and cons before deciding to breed your pets. Adoption is an alternative to breeding that can provide you with a healthy, happy crested gecko without the risks and responsibilities of breeding.

Adopting a crested gecko can also help to reduce the number of unwanted pets in need of homes. Many rescues and shelters have crested geckos available for adoption, and these pets can make wonderful companions for experienced reptile keepers.

The Bottom Line

In conclusion, while crested geckos do require mating to produce fertile eggs, it is possible for them to lay infertile eggs without mating. Parthenogenesis is a rare occurrence in crested geckos, but it has been observed in captivity. Breeding crested geckos can be a rewarding experience, but it is important to consider the risks and responsibilities before deciding to breed your pets. Adoption is an alternative to breeding that can provide you with a healthy, happy crested gecko without the risks and responsibilities of breeding.

Frequently Asked Questions

Do Crested Geckos Lay Eggs Without Mating?

Yes, female crested geckos can lay eggs without mating. This is known as parthenogenesis, which is the process of a female reproducing without fertilization from a male. However, the eggs laid through parthenogenesis are infertile and will not hatch into viable offspring. This means that if you want to breed crested geckos, you will need a male and female pairing.

It is important to note that not all female crested geckos will lay eggs through parthenogenesis. This is a rare occurrence, and it is more common for females to lay eggs after mating with a male. If you have a female crested gecko that has laid eggs without mating, it is essential to provide her with proper care and nutrition to ensure her health and well-being.

What Should I Do If My Female Crested Gecko Lays Eggs Without Mating?

If your female crested gecko lays eggs without mating, it is essential to provide her with proper care and nutrition. This includes a well-balanced diet that is high in calcium and vitamin D3, as well as proper hydration. You should also provide her with a suitable nesting area where she can lay her eggs.

It is important to note that the eggs laid through parthenogenesis are infertile and will not hatch into viable offspring. Therefore, there is no need to incubate the eggs or try to hatch them. Instead, you can dispose of them in a safe and hygienic manner. However, if you suspect that your female crested gecko is experiencing any health issues, such as egg binding, it is essential to seek veterinary care immediately.

Can Male Crested Geckos Lay Eggs?

No, male crested geckos cannot lay eggs. Only female crested geckos have the ability to lay eggs, either through mating with a male or through parthenogenesis. Male crested geckos do play an important role in breeding, as they are necessary for fertilization to occur. Therefore, if you are looking to breed crested geckos, you will need both a male and female pairing.

It is important to note that male crested geckos can still experience health issues related to breeding, such as sperm plugs and impaction. Therefore, it is essential to provide them with proper care and nutrition, as well as monitoring their behavior for any signs of health issues.

How Many Eggs Do Crested Geckos Lay?

The number of eggs that a female crested gecko lays can vary depending on various factors, such as age, health, and breeding conditions. On average, female crested geckos can lay 2-8 eggs per clutch, with multiple clutches possible throughout the breeding season. It is important to note that not all eggs will hatch into viable offspring, and some may be infertile.

If you are looking to breed crested geckos, it is essential to provide them with proper care and nutrition, as well as monitoring their behavior for any signs of health issues. You should also have a suitable nesting area available for the female to lay her eggs.

How Long Does It Take for Crested Gecko Eggs to Hatch?

The time it takes for crested gecko eggs to hatch can vary depending on various factors, such as temperature and humidity. On average, it can take anywhere from 60-90 days for the eggs to hatch. It is important to note that not all eggs will hatch into viable offspring, and some may be infertile.

If you are incubating crested gecko eggs, it is essential to provide them with proper temperature and humidity levels to ensure their viability. You should also monitor the eggs closely for any signs of health issues, such as mold or fungus growth, and seek veterinary care if necessary.

How often do CRESTED GECKOS lay eggs?


In conclusion, crested geckos are fascinating creatures that have captured the attention of many reptile enthusiasts. The question of whether or not they can lay eggs without mating has been a topic of debate for quite some time. While there have been rare instances where female crested geckos have laid eggs without being exposed to a male, it is not a common occurrence.

It is important to note that female crested geckos have the ability to store sperm for several months, allowing them to fertilize their eggs at a later time. Additionally, it is crucial to provide a suitable environment for your crested gecko if you are hoping to breed them successfully. This includes a proper diet, temperature, and humidity levels.

Overall, while it is possible for female crested geckos to lay eggs without mating, it is not something that should be relied upon. It is always best to provide a suitable environment for your gecko and allow them to mate naturally if you are hoping to breed them. As with any animal, it is important to do your research and provide the best care possible for your crested gecko.
