Crested geckos are fascinating reptiles that have gained popularity as pets in recent years. Their unique appearance, low maintenance requirements, and docile nature make them ideal companions for reptile enthusiasts. While they may seem visually similar, male and female crested geckos possess distinct physical and behavioral differences.

In this article, we will explore these differences, weigh the pros and cons of owning each gender, and provide guidance on how to determine the gender of your crested gecko and select the right one for you.

Physical Differences Between Male and Female Crested Geckos

In the world of crested geckos, there is more than meets the eye. While these fascinating creatures may appear similar at first glance, there are distinct physical differences between male and female crested geckos. Understanding these differences is essential for proper identification and care. 

In this section, we will explore the various physical characteristics that can help you determine the gender of your crested gecko, including size and weight variations, the presence of hemipenal bulges in males, the absence of pores in females, and differences in coloration.

Size and Weight

One of the most noticeable differences between male and female crested geckos is their size. Males tend to be slightly larger than females, with an average length ranging from 8 to 10 inches, while females typically measure between 7 and 8 inches. Additionally, males are usually heavier due to their larger bone structure and muscular build.

Hemipenal Bulges in Males

Male crested geckos possess prominent hemipenal bulges at the base of their tails. These bulges are a clear indicator of the animal’s gender and are absent in females. The presence of hemipenal bulges becomes more apparent as males mature, usually around 8 to 12 months of age.

Pores on Femoral Regions

Another distinguishing feature found in male crested geckos is the presence of pores on their femoral regions. These pores secrete a waxy substance called femoral secretions, which males use for territorial marking. Females, on the other hand, lack these pores, making it a reliable method to differentiate between the two genders.

Coloration Differences

While coloration can vary between individual crested geckos, there are some general patterns that differ between males and females. Males often exhibit brighter and more vibrant colors, including bold reds, oranges, and yellows. Females, on the other hand, tend to have more subdued coloration, featuring shades of brown, gray, or olive. However, it’s important to note that coloration alone is not a foolproof method for sexing crested geckos.

Behavioral Differences Between Male and Female Crested Geckos

When it comes to behavior, male and female crested geckos have unique traits that set them apart. From territorial behavior and aggression levels to breeding tendencies and vocalizations, understanding the behavioral differences between the sexes is crucial for providing appropriate care. 

In this section, we will delve into the distinctive behaviors exhibited by male and female crested geckos, including their territorial nature, breeding behaviors, vocalizations, and activity levels.

Territorial Behavior and Aggression Levels

Male crested geckos are known for their territorial behavior and can become aggressive toward other males if kept together. This aggression is particularly prominent during the breeding season when males may fight over females or establish dominance. Females, on the other hand, are generally more tolerant and less prone to territorial aggression.

Breeding Behavior and Potential

Males exhibit specific behaviors during the breeding season, such as head bobbing, vocalizations, and territorial marking, to attract females. They also possess pre-anal and femoral pores, which aid in the deposition of sperm during copulation. Female crested geckos, when ready to breed, develop plumper bodies and exhibit digging behavior when preparing to lay eggs.


Both male and female crested geckos are capable of producing vocalizations, but the purpose and frequency of these sounds may differ. Males often use chirping or barking vocalizations to attract females or establish territory, especially during the breeding season. Female vocalizations, on the other hand, tend to be less frequent and are often associated with stress or discomfort.

Activity Levels

Males are generally more active and display increased movement compared to females. They are known to be more exploratory and may spend more time climbing and jumping within their enclosure. Females, although active, exhibit a slightly calmer demeanor and tend to be more content staying in their preferred areas. This behavioral difference can influence the type of enclosure and enrichment you provide for your crested gecko.

Pros and Cons of Owning a Male or Female Crested Gecko

Deciding whether to bring home a male or female gecko requires careful consideration of the advantages and disadvantages associated with each gender. In this section, we will weigh the pros and cons of owning a male or female crested gecko. 

We will discuss factors such as lifespan, pricing, behavior and temperament, breeding potential, and compatibility with other geckos. By understanding the pros and cons of each gender, you can make an informed decision and choose the gecko that best aligns with your preferences and goals.


Both male and female crested geckos have similar lifespans, ranging from 15 to 20 years or even longer with proper care. The lifespan of your gecko will depend on various factors, including genetics, diet, habitat conditions, and overall health.


When it comes to pricing, male and female crested geckos are usually priced similarly, with variations depending on morphs, lineage, and availability. It’s important to note that the price can fluctuate within the reptile market, so it’s recommended to research prices from reputable breeders or pet stores.

Behavior and Temperament

Male crested geckos tend to be more territorial and may exhibit aggressive behavior towards other males. This aggression can make it challenging to house multiple males together. On the other hand, female crested geckos generally have a more docile temperament and are usually more tolerant of other geckos, making them easier to keep in groups or pairs.

Breeding Potential

If you’re interested in breeding crested geckos, owning a pair consisting of a male and female is necessary. Male geckos play a crucial role in the breeding process by courting females and fertilizing their eggs. However, breeding crested geckos requires careful planning, knowledge, and dedication, as it involves creating suitable breeding conditions and providing proper care for the eggs and hatchlings.

Compatibility with Other Geckos

When it comes to keeping crested geckos together, it’s generally recommended to avoid housing multiple males together due to potential territorial conflicts. Keeping a group of females together is often a better option, as they tend to coexist peacefully. However, it’s important to monitor their behavior and ensure they have enough space and resources to reduce the risk of aggression.

How to Determine the Gender of Your Crested Gecko and Choose the Right One

Determining the gender of your gecko is an important step in ensuring its well-being and happiness. In this section, we will provide you with practical guidance on how to determine the gender of your gecko and select the right one for you. 

We will explore methods such as examining the base of the tail and identifying hemipenal bulges, observing egg-laying behavior in females, consulting with professionals, such as veterinarians or reptile experts, and researching reputable breeders. Armed with this knowledge, you can confidently identify the gender of your crested gecko and make an informed decision when acquiring a new gecko for your collection.

Examining the Base of the Tail and Hemipenal Bulges

To determine the gender of your crested gecko, you can examine the base of the tail. Males will have noticeable hemipenal bulges located just above the vent, while females will have a more rounded and smooth appearance. This method is most reliable when the gecko is at least 8 to 12 months old.

Observing Egg-Laying Behavior

Female crested geckos will display specific behaviors when they are ready to lay eggs. They may become restless, exhibit digging behavior, and show a decrease in appetite. If you notice these signs, it’s likely that you have a female gecko.

Consulting with a Veterinarian or Reptile Expert

If you’re unsure about determining the gender of your crested gecko, it’s advisable to consult with a veterinarian or reptile expert. They can perform a physical examination and provide professional guidance in sexing your gecko accurately.

Researching Reputable Breeders

If you’re looking to purchase a crested gecko, especially a specific gender, it’s essential to research reputable breeders. Reputable breeders will have experience in sexing their geckos accurately and can provide you with the necessary information and documentation regarding the gecko’s gender.


Understanding the physical and behavioral differences between male and female crested geckos is crucial for reptile enthusiasts considering these charming creatures as pets. By recognizing the distinctions, you can make an informed decision when selecting the right gecko for your needs. Whether you choose a male or female crested gecko, provide them with suitable habitat, proper care, and a nurturing environment.

Male crested geckos exhibit larger sizes, prominent hemipenal bulges, and femoral pores, along with vibrant coloration. They tend to be more territorial, display breeding behaviors and may require separate housing to avoid aggression. 

Females, on the other hand, have a slightly smaller size, lack hemipenal bulges and femoral pores, and often exhibit more subdued coloration. They are generally more tolerant and can coexist with other geckos more easily.

Consider your specific preferences and goals when deciding between a male or female crested gecko. If you’re interested in breeding, a male-female pair would be necessary, but it requires careful planning and commitment. If you prefer a more docile and tolerant companion or wish to keep multiple geckos together, a female or a group of females may be the better choice.

When determining the gender of your crested gecko, consider methods such as examining the base of the tail, observing hemipenal bulges or the absence thereof, and monitoring behaviors like egg-laying in females. Consulting with a veterinarian or reptile expert can provide expert guidance and assurance. Additionally, researching reputable breeders ensures you acquire a gecko with accurate gender identification.

By understanding these distinctions and following appropriate methods to determine gender, you can choose the right crested gecko for your preferences and provide them with a loving and suitable environment for a happy and fulfilling reptile-human companionship.
