Are Geckos Born From Eggs? Everything You Need to Know About Geckos’ Reproduction

Geckos are distinguished by their unique features, such as their large, lidless eyes, sticky toe pads, and the ability to vocalize. Most geckos are small, ranging from a few centimeters to about 30 centimeters in length. They have a scaly body and are often brightly colored, making them a popular choice for pets.

Gecko Species

Geckos are found all over the world, from the deserts of the Middle East to the rainforests of South America. Some of the most popular gecko species include the leopard gecko, crested gecko, day gecko, and tokay gecko. Each species has its unique characteristics and behaviors, making them an interesting group of animals to study.

Gecko Reproduction: Basics

Geckos, like all reptiles, reproduce sexually. The process of gecko reproduction involves both male and female geckos, with males and females having distinct physical characteristics and behaviors.

Male and Female Geckos

Male geckos are typically larger and more brightly colored than females. They also have enlarged hemipenes, which are the reproductive organs of male reptiles. Female geckos, on the other hand, have smaller hemipenes and are usually less colorful than males.

Mating and Copulation

Geckos mate during the breeding season, which varies depending on the species and location. During mating, males will often approach females and court them with a series of behaviors, such as head bobbing, tail waving, and vocalizations. Once the female has accepted the male’s advances, copulation occurs, with the male inserting his hemipenes into the female’s cloaca.

Gecko Eggs: Everything You Need to Know

After copulation, female geckos will lay eggs, which are the primary method of reproduction for geckos. Gecko eggs come in a variety of sizes and types, with each species having its unique characteristics.

Types of Gecko Eggs

Gecko eggs can be classified into two types: hard-shelled and soft-shelled. Hard-shelled eggs are laid by species such as the leopard gecko, while soft-shelled eggs are laid by species such as the day gecko. Soft-shelled eggs are more fragile and require more care during incubation.

Size of Gecko Eggs

The size of gecko eggs varies depending on the species, with smaller species laying smaller eggs and larger species laying larger eggs. For example, the eggs of the crested gecko are about the size of a jellybean, while the eggs of the tokay gecko can be as large as a ping pong ball.

Gecko Egg Incubation

Gecko eggs must be incubated to hatch successfully. The length of incubation varies depending on the species, with some species taking only a few weeks and others taking several months. The temperature at which the eggs are incubated also plays a crucial role in determining the sex of the hatchling, with higher temperatures resulting in males and lower temperatures resulting in females.

Gecko Hatchlings: From Egg to Baby

Once the gecko eggs hatch, the hatchlings are born with a small yolk sac attached to their belly. This yolk sac provides the hatchling with the nutrients it needs to survive for the first few days of life.


Hatchlings emerge from the egg by breaking the shell with an egg tooth, a small, sharp projection on their snout. After hatching, the hatchling will absorb the remaining yolk sac, and within a few days, it will be ready to eat.

Gecko Hatchling Care

Gecko hatchlings require careful attention and care to ensure their survival. They need a warm and humid environment, with proper food and water. Hatchlings can be fed a diet of small crickets, fruit flies, and other small insects.

Growth and Development

Gecko hatchlings grow rapidly during their first few months of life, shedding their skin frequently as they grow. As they mature, the geckos will begin to display adult behaviors and characteristics, such as mating and territorial behavior.

Gecko Reproductive Health

Like all animals, geckos can experience reproductive problems that can affect their health and wellbeing. Some of the most common reproductive problems in geckos include egg binding, where the female is unable to pass an egg, and infertility, where males or females are unable to produce viable eggs or sperm.

Common Reproductive Problems

Egg binding is a common reproductive problem in female geckos, which can result in serious health issues if left untreated. Infertility can also be a problem, with females laying infertile eggs or males failing to produce viable sperm.

Preventing Reproductive Issues

Preventing reproductive issues in geckos involves providing them with a healthy and balanced diet, proper housing, and regular veterinary care. It is also essential to ensure that male and female geckos are housed separately, as males can become aggressive and territorial during the breeding season.


In conclusion, geckos are fascinating creatures with a unique method of reproduction. From their distinct physical characteristics to the types and size of gecko eggs, gecko hatchlings, and common reproductive problems, there is much to learn and appreciate about these amazing lizards. Whether you are a gecko enthusiast or just curious about these fascinating creatures, understanding their reproductive biology is an essential part of appreciating their place in the natural world.
