I know for sure one is a female - thoughts on the other two? They are 7 weeks old, each photo is of the same three gerbils. There are 3 other boys in the litter (not pictured), and they all have obvious testes at this point. The two with the dark line and the seemingly increased space between holes are throwing me for a loop!

The surest way to sex gerbils (aside from looking for testicles in older gerbils) is to look closely for a vaginal opening underneath the urethra (the little bump) but above the anus. If you see an opening, you have a female. It's not usually easy to see from photos though. Ano-genital distance is a very good indicator too but not perfect since it's slightly more subjective. If you have a look at my photo of a female in this thread you can just about see an opening under her urethra. Maybe if one of my girls is in a co-operative mood tomorrow I will try to get a clearer photo. |
