When Do Gerbils Reach Maturity? A Guide to Gerbil Reproduction

Gerbils are small rodents that belong to the subfamily Gerbillinae. There are over 110 species of gerbils, and they are found in arid regions of Africa and Asia. The most common species of gerbil kept as pets is the Mongolian gerbil, which is native to Mongolia and China.

Gerbils are social animals that live in burrows in the wild. They are active and curious creatures that need plenty of mental and physical stimulation to thrive in captivity. Gerbils are herbivores that feed on seeds, grains, fruits, and vegetables.

Why is Gerbil Maturity Important?

Understanding gerbil maturity is critical for pet owners to manage gerbil reproduction effectively. Gerbils reach sexual maturity relatively early in life, and they can breed rapidly if allowed to do so. Proper management of gerbil reproduction is essential to prevent overpopulation and ensure the health and well-being of the animals.

Gerbil Maturity

Gerbil Sexual Maturity

Gerbils reach sexual maturity at around 3-4 months of age, which means they are capable of reproducing at a relatively young age. Male gerbils become sexually mature before females, and they can start exhibiting mating behavior as early as 8 weeks of age.

It is crucial to separate male and female gerbils before they reach sexual maturity if you do not plan to breed them. If allowed to breed, gerbils can produce several litters per year, which can lead to overpopulation and health problems.

Signs of Gerbil Maturity

Apart from sexual maturity, other signs of gerbil maturity include physical changes and behavioral changes. Physically, mature gerbils tend to be larger and heavier than younger gerbils. They may also develop more prominent scent glands, which they use to communicate with other gerbils.

Behaviorally, mature gerbils tend to be more assertive and dominant than younger gerbils. They may also exhibit more territorial behavior and become aggressive towards other gerbils if they feel threatened.

Factors Affecting Gerbil Maturity

Several factors can affect the age at which gerbils reach maturity. These include genetics, diet, and environmental factors such as temperature and light exposure. Generally, gerbils that are well-nourished and kept in a stable environment with proper lighting tend to mature faster than those that are not.

Gerbil Reproduction

Gerbil Reproductive System

The female gerbil reproductive system consists of two ovaries, two oviducts, and a uterus. The male gerbil reproductive system includes two testes, a prostate gland, and seminal vesicles.

When a female gerbil is in heat, she releases pheromones that attract male gerbils. Once a male gerbil detects these pheromones, he will begin to display mating behavior, including chasing, mounting, and copulation.

Gerbil Breeding Process

Gerbil breeding is relatively straightforward, but it is essential to understand the process to ensure a successful outcome. Before breeding gerbils, it is crucial to ensure that they are healthy and free from any diseases or infections.

The breeding process involves introducing a male and female gerbil into the same habitat and allowing them to mate naturally. Gerbils are monogamous animals, which means that they will typically mate with one partner for life.

If successful, the female gerbil will become pregnant, and after a gestation period of around 24-26 days, she will give birth to a litter of pups.

Gerbil Gestation Period

The gestation period for gerbils is around 24-26 days, during which time the female gerbil will carry the pups in her womb. The number of offspring in a litter can vary, but it is usually between 3-6 pups.

Gerbil Offspring

Gerbil Litter Size

Gerbil litter sizes can vary, but the average litter size is around 3-6 pups. The litter size can be affected by several factors, including the age and health of the parents, the environment, and the quality of the food they eat.

Gerbil Offspring Care

Gerbil offspring are born blind and hairless, and they are entirely dependent on their mother for food and warmth. The mother gerbil will nurse the pups until they are weaned at around 21 days of age. After weaning, the pups can be separated from their mother and cared for separately.

Gerbil Offspring Development

Gerbil pups develop rapidly, and they can reach sexual maturity as early as 3-4 months of age. It is essential to provide them with a healthy and stimulating environment to ensure their development.

Gerbil Reproduction Management

Gerbil Reproduction Control

If you do not plan to breed gerbils, it is crucial to control their reproduction to prevent overpopulation. One way to do this is by separating male and female gerbils before they reach sexual maturity. Another option is to have them neutered or spayed, which can prevent them from reproducing.

Gerbil Breeding Dos and Don’ts

If you plan to breed gerbils, there are several dos and don’ts to keep in mind. It is crucial to ensure that the gerbils are healthy and free from any diseases or infections before breeding them. You should also provide them with a clean and stimulating environment to encourage successful mating and gestation.

It is essential to avoid inbreeding, as this can lead to health problems in the offspring. You should also avoid breeding gerbils too frequently, as this can put a strain on the female gerbil’s health.

Gerbil Reproduction Risks

Breeding gerbils can come with various risks, including health problems in the offspring, injury or death during mating, and complications during birth. It is essential to understand these risks and take steps to minimize them, such as providing proper nutrition and veterinary care.


In this guide, we have explored the topic of gerbil maturity and reproduction in detail. We have answered common questions such as what age can gerbils get pregnant and when can gerbils get pregnant, and provided guidance on managing gerbil reproduction effectively.

Understanding gerbil maturity and reproduction is crucial for pet owners to ensure the health and well-being of their animals. By following best practices for gerbil reproduction management, you can provide your gerbils with a safe and stimulating environment to thrive in captivity.
