How Can You Tell If a Rabbit Is a Male or Female?

Gently pressing on the area on either side of the opening below the anus will make the genitals pop out. Male rabbits have a penis or a shaft with an open end. Male rabbits will also have noticeable testicles appear between 9 and 20 weeks of age, which should be present unless the rabbit has been fixed. Female rabbits will have a vaginal opening become visible, and there aren't any testicles in the area.
