All guinea pigs have nipples regardless of gender.

Answer 2

To be honest both gender of Guinea pigs have nipples, so they are no help in deciding which s*x you have.

If you notice a puckered (irregularly folded) looking spot just above the genital area, it's a good possibility that you're holding a male.

Next, press gently just above the genital area. If the guinea pig is a male, his p***s should come out. If the guinea pig is young, you can also examine the area around the animal's r****m. A donut-shape also signifies a male because this is where the guinea pig's testicles are located.

Hope this will help you.

Answer 4

No, I don't think any sort of mammals can change gender, maybe he is getting man b***s like tubby men do.

Answer 5

One may be developing testes.  Are they right above the hind legs?  And to double check the gender, boars have enlarged genital areas, sows don't.
