How to tell the sex of a Hamster ?

Knowing the sex of your hamster is a must in case you want it to reproduce. It can also be interesting in order to know its physiognomy, to prevent its reactions and behavior. A female will have periods of heat and will see her mood change. You have to be prepared for this, unless you decide to spay her, or castrate her.

Sexing at birth

You don’t have to wait long to find out the sex of a hamster. This can be done from birth. Simply turn it over by circling its thorax with your thumb and index finger. However, avoid this technique, which can be dangerous for your rodent if you do not have the hand or the experience for such a procedure. If you can see the lower abdomen of your hamster, you will notice that the distance between the anus and the genital tract of the male is greater than that of the female. At birth, the distance is about 6 mm in males and 1 mm in females. Of course, this becomes obvious once your hamster is an adult.

Sexing in adulthood

Same procedure as for the hamster at birth. But this time the visibility is much better. For example, you will notice that the distance between the anus and the genital apparatus of your male hamster is much greater than that of the female. Moreover, in a female hamster, the anus, urethra and vulva are clearly visible to the naked eye.

Rows of rosy nipples can be seen on its belly. All this is visible after 4 weeks of life.

In a male, on the other hand, you will have to wait 5 to 9 weeks to see his testicles. Before that, they are stuck in his abdomen.

Finally, the last method: the croup. It is more rounded in a female dwarf hamster than in a male dwarf hamster. Conversely in the Chinese or golden hamster. More elongated in the female than in the male.

A male and a female together ?

If you venture on the path to reproduction, sexing your hamsters is essential. On the other hand, if you have no desire to have a litter of baby hamsters (they can be up to 12), then you must imperatively separate the males and females before their sexual maturity, otherwise an unwanted gestation will occur before your eyes.
