The female genital tract originates from the Müllerian ducts during embryological development. Fusion of the ducts occurs in different segments depending on the animal species, resulting in a variational number of the respective organ. Current literature on genital tract morphology of laboratory rodents is controversial. Therefore, the present study aimed at determining an anatomically correct definition of the uterus in laboratory guinea pigs, mice and rats. In all three rodent species, we found two separate cervical canals that communicate with an individual uterus via discrete ostia uteri interna . The correct anatomical definition should therefore be uterus duplex bicollis , vagina simplex .
