Sexing Hamsters

By Luna Bug
Sexing hamsters can be tricky, especially when they are young.
Syrian males are usually more obvious. Once they have reached 4 weeks old they will have noticeable testicles that hang down below the rear end.
Male Dwarves will have testicles as well, but they are less obvious. Also male Dwarves have a scent gland near the umbilicus (belly button). All male hamsters are capable of retracting their testicles up into the abdomen.
Female Syrians, if the hair is short enough, will have noticeable nipples. There are two rows of nipples that run parallel on either side of the belly. Female Dwarves also have nipples, but they are typically much smaller and much harder to see.
The easiest way to tell if your hamster is a male or female is to look at the distance between the two openings at the rear. This is the same with all hamsters, male or female.
In males the anus (opening for excreting feces) and the penis (which is kept tucked up inside a small opening) are further apart. In females the anus (opening for excreting feces) and the vaginal opening (which leads to where the female organs are located) are much closer together in comparison to the male.
