How to Tell if a Gerbil Is Male or Female

Do you have a gerbil and can’t tell if it’s a girl or a boy? How do you tell if a gerbil is male or female? Not to worry; with a few simple steps, you can easily gender-identify your little furry friend.

Knowing the physical and behavioral differences between male and female gerbils can make all the difference in providing the best care for your pet.

Let’s go back in time and explore the ancient art of gerbil sexing. We’ll cover the basics of gerbil anatomy, physical characteristics, and behavioral differences so that you can confidently determine the sex of your gerbil.

Key Takeaways

  • Sexing gerbils is crucial for understanding them, providing appropriate care, and implementing breeding methods.
  • Gerbils have distinct physical features that can help in determining their sex, such as size, head shape, tail thickness, and the presence of scrotal sacs in males.
  • Behavioral differences between male and female gerbils can also aid in sex identification, with males exhibiting more aggressive behavior during mating season.
  • When sexing a gerbil, look for a light-colored stripe down the back of males, observe feeding habits, examine scent glands, and check for a prominent bulge near the genitalia in males.

Sex Identification

Identifying a gerbil’s sex is an important step in understanding them. Breeding methods are often used to sex a gerbil, as males and females usually look similar in size and shape. The most reliable way to identify a gerbil’s sex is to look for sexing methods which include checking for scrotal sacs and nipples.

Male gerbils have scrotal sacs, which are two small lumps located beneath their tail near their rear legs. Female gerbils have nipples located on their underside, just behind their front legs. It’s possible to check for both of these characteristics by gently holding the gerbil and turning it over.

If you’re unsure, it’s best to consult a veterinarian who specializes in small animals. They can accurately identify the sex of your gerbil and provide advice on gerbil care and breeding methods.

Gerbil Anatomy

Now that you know how to identify a gerbil’s sex, let’s take a look at the anatomy of this small mammal. Gerbils are social animals with distinct physical features that vary from male to female. To understand the differences, let’s look at a few of the key characteristics.


In terms of breeding habits, male gerbils are most active when kept with two or more females, while females will become agitated if kept with more than one male. Females also tend to be more territorial, so it’s important to provide them with their own space. Knowing the differences between male and female gerbils can help owners ensure they are socializing them properly.

Physical Characteristics

By examining their physical characteristics, you can easily tell the difference between a male and female gerbil. Generally, female gerbils are smaller than their male counterparts, with a smaller muzzle and smaller claws. Female gerbils tend to have rounder bellies and smaller heads in comparison to males.

Moreover, when it comes to breeding differences, male gerbils have certain bumps on their undersides that aren’t present in females. These bumps are called ‘scrotal sacs” and are used in mating habits.

Lastly, the tails of male gerbils are thicker and longer than female tails, and they have got a larger gap between their anal and genital openings.

Behavioral Differences

Moving on from physical characteristics, behavioral differences can also help you tell if a gerbil is male or female. For example, male gerbils will exhibit more aggressive behavior during mating season. During this time, they will become territorial, competing with other males for access to females. On the other hand, female gerbils tend to be more passive. They will seek out social cues from their environment rather than competing with males.

Behavioral differences can also be seen in gerbils’ breeding habits. For example, females tend to take a more active role in raising their young. They will remain with their offspring until they have reached adulthood. Males, on the other hand, will leave after mating and may even reject their own young.

Sexing Your Gerbil

Four easy steps can help you accurately sex your gerbil.

First, look at the gerbil’s coat patterns. Males tend to have a light-colored stripe down their back that females lack.

Second, take note of the feeding habits of your gerbil. Males tend to be more aggressive eaters, often pushing other gerbils away from the food dish.

Third, observe your gerbil’s scent glands. Males have a more pronounced scent gland than females.

Finally, examine the area around the gerbil’s genitalia. Males have a prominent bulge near the genitalia that females lack.

By following these four steps, you can easily and accurately determine the sex of your gerbil. Remember to be gentle and patient when sexing your gerbil, as the process can be uncomfortable for the animal.

With the proper knowledge and care, you can easily know the sex of your gerbil and provide it with the best possible care.


Knowing how to tell the difference between a male and female gerbil can help you better care for your pet. With a bit of knowledge and observation, you can easily determine the sex of your gerbil.

Whether it’s the physical characteristics, behavior, or anatomy, you can now be confident in your gerbil sexing skills.

Now that you know how to tell, you can look forward to a long and rewarding relationship with your furry friend!
