Male guinea-pigs can start mating when they are as young as 3 weeks old, although it is recommended that you make sure they been bred by six months old to make them a breeder.

Female guinea pigs can start having babies when they are three months old, however, it is highly recommended that you don't mate them when they are over a year old, due to pelvis bone fusion. A female guinea pig any older than a year old will have a dead litter before she will be able to produce a live litter.

Female guinea pigs are able to get pregnant as soon as 3 weeks. That's why it's important to separate them from males around that time.
10 weeks, but it is best if you want to breed them to allow them to get pregnant at 12 weeks

Guinea pigs are a rodent and they are made to breed quickly. A guinea pig can breed at a young age of 3 months old. As soon as babies are eating on their own, the males should be separated from their mother. The males will mate with her if they get a chance.

Guinea pigs can reproduce when they are as young as four weeks, but this is not good for them. If you have baby males and females in together, they should be separated by then.

It is healthiest to breed your female guinea pig between the ages of four and seven months. DO NOT wait until they are older than eight month to breed them for the first time as the pelvic bones may be fused together by then, instead of being flexible enough to allow for easy delivery.

When do male guinea pigs become fertile?

Male guinea pigs have been known to make a female pregnant when they are only a month old. But usually the male becomes fertile and wants to breed around 3-6 months of age. If you are planning on breeding, I suggest not to because the risk that the female will die giving birth or that she will give birth to "lethals" (babies without eyes or have crooked teeth) is high.
