“…The diagnosis of reported cases of uterine segmental aplasia was possible through macroscopic analysis of the reproductive system. In Brazil, no report of a unicorn uterus was found in sheep, but it has been reported in other species such as bitches (PINTO FILHO et al, 2001;PAGLIUCA et al, 2012;AGUIRRA et al, 2014), cat (CORREIA et al, 2018), cow (ANDO et al, 2007) and buffalo (OHASHI et al, 2012;RIBEIRO et al, 2016). In studies with bitches, despite the uterine malformation, there were no changes in the ovaries and the presence of these organs is justified by the embryonic origin different from the uterus (PAGLIUCA et al, 2012;SÔNEGO et al, 2018), which was also verified in the present report.…”
