Answer
Hi Kayla,

    Hold your hamster so that you can see their tummy, look at the private area, A male hamster will have 2 holes ( .  . ) far apart, depending on their age, you may also see 2 lumps (testicles), one on each side of the bottom hole. A female will also have 2 holes ( .. ), but they are closer together (may appear as only 1 hole).
     If you have anymore questions, please write again.

Thanks for writing!
