Why Learn to Sex Your Crested Geckos?

Before we dive into the nitty-gritty, let's talk about why it's essential to know the sex of your crested geckos. For one, it helps you create the perfect pair for breeding, ensuring you get healthy, happy geckos. Plus, it's crucial for managing your collection, as male geckos can be territorial and aggressive towards each other.

When Can You Sex Crested Geckos?

The good news is that you can tell the sex of your crested geckos relatively early. While it's not always 100% accurate, you can typically sex them around 6-8 months of age, or when they're about half the size of an adult. However, some experienced keepers can sex them as early as 4-5 months. Let's explore the key differences between male and female crested geckos.

Male Crested Geckos: Spotting the Boys

Vocal Sacs

One of the most obvious differences between male and female crested geckos is the presence of vocal sacs. As the name suggests, these are small, sac-like structures located on either side of a male's throat. When a male is vocalizing, these sacs will inflate and deflate, amplifying his calls.

Pro tip: To see the vocal sacs clearly, try shining a light from below your gecko. The light will make the sacs more visible.

Hemipenes

Another way to tell the sex of your crested geckos is by looking at their hemipenes. Now, don't worry, we won't be performing any invasive checks. Instead, we can look for the pre-cloacal pores, which are small, raised bumps around the cloaca (the opening where waste and reproductive products exit the body). In males, these pores are more numerous and larger than in females.

Warning: Be gentle when handling your geckos, especially around the tail. A stressed gecko may release a foul-smelling substance called "gecko poop" (yes, that's a technical term).

Female Crested Geckos: Spotting the Girls

Larger Size

Female crested geckos tend to be larger than males, with a more robust body and a wider head. While this isn't always a reliable indicator, it can be a helpful clue, especially when looking at younger geckos.

Egg Laying Pouch

One of the most surefire ways to tell if your crested gecko is female is to look for an egg-laying pouch. This is a small, fleshy pouch located on the underside of the tail, near the cloaca. When a female is ready to lay eggs, this pouch will become more prominent and filled with eggs.

Fun fact: Crested geckos can lay up to three clutches of eggs per year, with each clutch containing one to three eggs.

Sexing Crested Geckos: A Step-by-Step Guide

Alright, let's put it all together and learn how to sex your crested geckos in a step-by-step process:

1. Gently handle your gecko: Start by carefully picking up your gecko, supporting its body and tail to prevent any stress or injury.
2. Check for vocal sacs: Look at the sides of your gecko's throat. If you see small, sac-like structures, it's likely a male.
3. Examine the pre-cloacal pores: Gently part the gecko's tail scales to reveal the cloaca. Count the number of pre-cloacal pores and look for size differences. In males, these pores are more numerous and larger.
4. Observe the size and shape: Compare your gecko's size and head width to other geckos of the same age. Females tend to be larger and more robust.
5. Look for an egg-laying pouch: In females, this pouch will become more prominent when she's ready to lay eggs.

Sexing Crested Geckos: Common Misconceptions

Now that we've covered the basics, let's address some common misconceptions about sexing crested geckos:

Myth: You can sex crested geckos by their color or pattern.

Fact: While there may be some slight differences in color and pattern between males and females, these are not reliable indicators of sex.

Myth: It's easy to sex crested geckos when they're young.

Fact: While it's possible to sex crested geckos at a young age, it's not always 100% accurate. Always wait until your gecko is at least 6-8 months old before attempting to sex it.

Myth: You can sex crested geckos by their behavior.

Fact: While males may display more territorial behavior, this is not a reliable way to sex your geckos. Both male and female crested geckos can exhibit a wide range of behaviors.
