How can I tell if my guinea pig is male or female?

In order to ensure the sex of a guinea pig, we must wait until it is 3 or 4 months old. Before we can look at it, but it can always be that because of its young age we make a mistake when identifying the sex.

In order to distinguish the sex of our guinea pig, we must put our guinea pig on its back in the way that feels safest. To be able to be on top of our legs while sitting. Once in position, we can separate her legs and see what her sex is.

As we can see, the female genitalia is shaped like a Y, while the male is shaped like an i.

If you still do not finish seeing clearly what sex it is, you can apply slight pressure with the index and thumb fingers (putting them on one side and the other) on the genital area to see if the male member appears and thus fully confirm if Is it male or female.
