Most non-human mammals have a non-single uterus with separation of horns. Marsupials and rodents have a double uterus (uterus duplex).
Marsupial reproductive organs differ from placentals. For them, the reproductive tract is doubled. Females have two uteri and two vaginas, and before birth, a birth canal forms between them, the median vagina. [7] In most species, males have a split or double penis lying in front of the scrotum, [8] which is not homologous to the placental ...

There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus). [ 1 ] [ 2 ] A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus .
