Sexing Pregnant males?

Hi everyone :)

Me and my boyfriend brought home 2 male guinea pigs 3 months ago. One is 4 months old, the other 6 or 7 months.

In April, we found an aborted fetus inside their cage - it had the mouth, teeth and nose formed but no eyes.

We naturally assumed one of the pigs was a female and waited a couple of months before checking to figure out which one would it be.

Nothing else (babies or apparent pregnancy) happened in the meantime so we checked again today. And, according to every online sexing guide, they're both males. :eye-poppi

Any ideas...?

Thanks!
 
I think I'd take them to an exotic vet to confirm whether they are male or female.
 
Some guinea pigs can have ambiguous genitalia, just like people can. Usually the females can't get pregnant, but apparently you have one that can.

Have you seen the pictures at Sexing Guinea Pigs: How to Sex a Guinea Pig

And can you post pictures here of the pertinent parts of both pigs?

My recommendation is that you separate them until you figure out which is which, rather than leaving them together for the female to get pregnant again. In addition to an apparently high risk of dead/deformed pups, you're putting the sow at risk also.
 
Yes. Separate them until you figure out the gender. Are there any rescues in your area that can help you determine it?
