Uterus didelphys (sometimes also uterus didelphis) represents a uterine malformation where the uterus is present as a paired organ when the embryogenetic fusion of the Muellerian mÃ¼llerian ducts fails to. Occur as a result there is a double uterus with two separate, cervices and often a double vagina as. wellach uterus has a single horn linked to the ipsilateral fallopian tube that faces its ovary. In non human species (e.g. nematodes), a didelphic genital tract may be normal rather than a malformation.
