Male hamster or female hamster: how to distinguish them?

When adopting a single hamster, knowing its gender is not always very important, unless you want to give it a very personal name or better understand its reactions and behavior. On the other hand, if you want to have multiple hamsters to live together and/or breed, it’s a good idea to know their gender to maximize your chances of success. Check out our tips to easily and reliably tell a male hamster from a female.

How to tell a male and a female hamster at birth?

From birth, you can find out the sex of a hamster. To do this, simply gently turn the animal over, holding it by the ribcage between thumb and forefinger. This manipulation must be carried out carefully and meticulously, because the hamster is fragile. It’s best to leave this to a regular professional if you don’t feel capable of doing it so as not to harm, scare or stress the animal.

By observing the distance between the genitals and the anus of the hamster, you can determine whether it is a male or a female. Indeed, in the male this distance is much greater, since at birth it averages 6 mm against only 1 mm in the female.

How to distinguish between a male and a female hamster in adulthood?

Whether you want to specifically adopt a male or female hamster, or just want to know the gender of your new little companion, just watch the adult animal.

Proceed in the same way, gently turning the hamster over. Hold him in the palm of your hand, not so hard that he doesn’t choke or hurt him, but hold him just enough that he doesn’t twitch and risk injury.

Pay attention to the distance between the anus and the genitals of the animal, which is always much greater in the male. Moreover, it is easier to determine the sex, because the vulva and rows of nipples on the abdomen are clearly visible in the female from the age of 4 weeks. In males, testicles are visible at 5 to 9 weeks of age, depending on the individual.

The croup can also help you tell a male from a female, but this depends on the type of hamster. In a dwarf hamster, the croup of the female is more rounded than that of the male. On the contrary, the sacrum is more elongated in the female than in the male in the case of the Chinese hamster and golden hamster.

You can keep males and females together if you want them to breed. However, be careful, because you should know that 12 babies can be born in a litter! If you want to avoid breeding without spaying or regulating your animals, separate males from females by differentiating them with our methods.

Is it better to take a male or female hamster?

If you only want to adopt one or two individuals and are unsure of the gender, know that males and females are more or less easy to live with depending on the subspecies of the hamster.

  • golden hamster : The golden hamster is easiest to live with males. Females are known to be more restless, more fragrant in estrus, and much larger. On the other hand, it should be noted that this type of hamster lives alone, whether male or female. So be content with a companion or separate them from 5 weeks of age if you have more than one.
  • Chinese hamster : The male and female Chinese hamster are very similar both physically and behaviorally. Therefore, you can accept one or the other without problems. However, if you want to raise multiple hamsters, give preference to male hamsters because they are easy to get along with and get along much better than females, who value social life less. This should not prevent you from remaining vigilant, because a fight may break out between males. In this case, you will need to separate them immediately and permanently.
  • Russian hamster : The Russian hamster is similar to the Chinese hamster. Males and females are similar to each other physically and behaviorally, but males coexist better with each other than females, who are less sociable. However, here too, if you are accepting multiple males, remember that a dispute may arise and therefore you will have to immediately and permanently separate the individuals, which implies two separate habitats if necessary.
  • roborovsky hamster : this species of hamsters is still little known, but it would seem that males and females are similar in every way. Roborovski hamsters are physically similar, exhibit the same type of behavior, and tolerate each other very well, regardless of gender.
  • Campbell’s hamster : Male Campbell’s hamster and female Campbell’s hamster are almost the same size. On the other hand, like the Russian hamster and the Chinese hamster, males coexist better with each other and are recommended for breeding in the community. Women tend to quarrel frequently.
