Are you a proud owner of a Tokay Gecko but unsure of its gender? Knowing the sex of your gecko is essential for its health and well-being, as it determines the type of care and diet it needs.

However, determining the gender of these feisty creatures can be tricky, especially for beginners.

That’s why we’ve put together this comprehensive guide on how to sex your Tokay Gecko.

From signs that differentiate male from female geckos to the age and size at which they can be sexed, we’ll cover everything you need to know.

Why Sex Your Tokay Gecko?

Sexing your Tokay Gecko is essential in ensuring its health and happiness. Knowing the gender of your gecko is important because it helps you provide them with the appropriate care, diet, and living conditions.

For example, female Tokay Geckos require different lighting conditions and diets than males, and mistaking their gender could lead to health problems.

Moreover, knowing the gender of your gecko is also important if you plan to breed them.

Breeding geckos without knowing their gender can lead to aggressive behavior and stress, which could ultimately lead to a decrease in their lifespan.

Sexing your Tokay Gecko can also help you determine the size and weight it should be, which can help you monitor their overall health.

How To Sex Your Tokay Gecko

Sexing your Tokay Gecko can be done by observing physical characteristics that differ between males and females.

Males are typically larger than females and have a more robust appearance. They can grow up to 13-16 inches in length.

Females, on the other hand, are usually smaller and can grow up to 8-12 inches.

The easiest way to determine the gender of your Tokay Gecko is by examining the pre-anal pores, which are small bumps above the cloaca.

Signs That Differentiate Male from Female Tokay Geckos

Male and female Tokay Geckos have certain physical differences that can help differentiate between them.

Males range from about 13 to 16 inches in length, while females range from 8 to 12 inches. Additionally, males are generally larger than females and appear more robust.

One of the most prominent signs that can help determine the sex of Tokay Geckos is the presence of pre-anal pores.

These pores are more pronounced in adult males and are absent in females. Males also have slight hemipenile bulges at the base of the tail, which is not present in females.

Another distinguishing characteristic is the coloration and pattern of the Tokay Gecko.

Male Tokay Geckos are usually brighter and more vivid, while females tend to be duller in color.

Males also have a more defined pattern than females, with black spots that form an irregular shape around the neck and shoulders.

It is important to note that some of these characteristics may not be noticeable in juvenile Tokay Geckos, and it is best to wait until they reach adulthood before attempting to sex them.

How Old Does Your Tokay Gecko Need to Be Before Sexing?

It’s recommended to wait until your Tokay Gecko has reached sexual maturity (12-24 months old) before attempting to sex them.

While it is possible to differentiate between the sexes as much earlier, waiting until they are a bit older can help increase the accuracy of the process.

This is because the characteristics that distinguish males from females may not be as noticeable in juveniles.

It is important to note that sexing a Tokay Gecko is not easy and should only be attempted by experienced individuals.

It is also essential to handle the gecko with care during the process to prevent any harm or stress.

How Big Should Your Tokay Gecko Be When Sexing?

When it comes to sexing your Tokay Gecko, it is important to take into consideration its size.

Male Tokay Geckos are generally larger than females, ranging from about 13 to 16 inches, while females typically measure 8 to 12 inches in length.

Therefore, the size of your Tokay Gecko can be an indication of its sex.

Another way to determine the sex of your Tokay Gecko is by examining the shape of its body.

Male Tokay Geckos tend to have a more robust appearance with bright colors, while females tend to be slenderer and have dull colors compared to males.

It is important to note that the size of a Tokay Gecko alone may not be a definitive way to determine its sex.

Other signs, such as the presence of pre-anal pores and hemipenile bulges, should also be taken into consideration.

When Should You Sex Your Tokay Gecko?

Genetics determines the sex of Tokay geckos. Males have raised pre-anal pores that form a V-shape right above their cloaca.

Females lack these pores and have a spherical cloaca. While captive tokays may generally mate at any time of year, offering seasonal changes may help boost breeding.

Overall, it’s best to wait until your Tokay Gecko is at least 18-24 months old and to ensure that it’s healthy and stress-free before attempting to sex it.

It’s also important to seek guidance from experienced reptile keepers or veterinarians to ensure accurate and safe sexing of your gecko.

Can A Tokay Gecko Change Its Gender?

No, the gender of Tokay geckos is determined by their chromosomes, which means they cannot change their gender.

Once a Tokay gecko has been identified as either male or female, it will remain that gender for the rest of its life.

This is because sex is determined by genetics and once that determination is made, it cannot be changed.

While some species of reptiles can change their gender in response to environmental factors, this is not the case for Tokay geckos.

They do not have the ability to change their gender, even if they are kept in different conditions or subjected to different environmental factors.

This is because gender in Tokay geckos, as in most reptiles, is determined by genetics rather than environmental factors.

It’s worth noting that some male Tokay geckos can exhibit behavior similar to that of a female, such as laying eggs.

However, this does not mean that the male has changed gender. Instead, it is likely that the male has a hormonal imbalance that is causing this behavior.

FAQs

How old does my Tokay Gecko need to be before sex?

Tokay Geckos can be accurately sexed after they have reached sexual maturity, which occurs at around 12-24 months of age.

What is the required size to establish the sex of a Tokay Gecko?

The size of a Tokay Gecko is not necessarily a good sign of sex. However, males are often larger than females.

Males can range in length from 13 to 15 inches, while females are typically slightly shorter, averaging 8 to 12 inches.

It is essential to note, however, that size alone is insufficient to reliably establish the sex of a Tokay Gecko; other physical traits and behaviors must also be considered.

Summary

Sexing your Tokay Gecko is important to ensure that you provide the right environment, diet, and socialization for your pet.

The signs that differentiate male from female Tokay Geckos are the size and shape of their body, tail, cloaca, and hemipenal bulges in males.

Tokay Geckos should at least reach sexual maturity (12-24 months old) before attempting to sex them.

Additionally, sexing your Tokay Gecko should be done in a stress-free environment, such as during a routine cleaning or feeding.

Unlike, some other reptiles, Tokay geckos cannot change their gender.

However, sometimes due to hormonal imbalance, males can exhibit characteristics of females, like laying eggs but this does not mean that the Tokay gecko has changed its gender.

By following the tips and guidelines outlined above, you can ensure that your Tokay Gecko thrives in its environment and lives a healthy, happy life.
