Pathology of the mare reproductive system

Abstract

Pseudohermaphrodites are rare in the equine species. In these animals the chromosome constitution and gonadal sex are in agreement, yet the internal or external genitalia are ambiguous. There is one type of gonad, by which the individual is classified, and ducts modified toward those of the other gender. In animals, male pseudohermaphrodites are more common than female pseudohermaphrodites which are rare; for many of these abnormalities the mechanisms are not understood.
