“…The present case had functional ovaries, as indicated by the presence of growing follicles on the left ovary and a corpus luteum on the right one, which indicated normal cyclic activity of the ovary. Clinical studies have reported that congenital anomalies due to the fusion failure of the Müllerian ducts are associated with reproductive difficulties ( 35 ). Ishiyama, Nakamura ( 36 ) reported that severe cases of incomplete fusion, such as double external os with a blind diverticulum, complete double cervix with blind diverticulum, and uterus didelphys, are associated with infertility in cattle, while the double cervix and external cervical os increase the incidence of dystocia in animals ( 9 , 33 ).…”

BackgroundUterus didelphys is a rare congenital anomaly of the female reproductive tract characterized by a divided uterine cervix and body. It occurs due to abnormal development of the paramesonephric (Müllerian) duct. Different forms of uterus didelphys have been reported in several animal species, including bovine, equine, ewe, goat, swine, and bitch. However, there is no previous report that has documented a completely divided female genital tract in she-camel. Moreover, there is a lack of literature regarding this anomaly in animals. Therefore, the present study reports, for the first time, a rare case of a completely divided female genital tract in a she-camel. In addition, the existing relevant literature on uterus didelphys in different animal species is reviewed.Case presentationA female reproductive tract of she-camel, approximately 10 years old, with a history of previous successful pregnancy, was brought to the anatomy department following the slaughtering of the animal. Initial examination revealed a normal reproductive tract consisting of two ovaries, two fallopian tubes, a uterus, and a vagina. A closer examination revealed a completely divided vagina, with an external os opened into each part of the vagina, as well as a divided uterine body and cervix. Intrauterine infusion of saline through one external os confirmed complete separation of uterine body and cervix.ConclusionTo the authors’ knowledge, this is the first reported case of a completely divided female genital tract in a she-camel. This review summarizes the previous reports about uterus didelphys in farm animals.
