[Intersexuality in domestic mammals]
1INRA, Laboratoire de Cytogénétique, Jouy-en-Josas, France.
Abstract:
With the exception of bovine freemartinism, intersexuality is rarely reported in domestic animals. The few cases of intersexuality reported here in dogs, cattle, goats, sheep and horses were classified according to the karyotype. The XX intersexes described here included goats which were either polled male pseudohermaphrodites or true hermaphrodites and dogs which were female pseudohermaphrodites. Among the XY intersexes studied, one dog was a true hermaphrodite, whereas the others were male pseudohermaphrodites, all mares showed gonadal dysgenesis and one cow was a female pseudohermaphrodite. XX/XY intersexes were detected in ovine cases of freemartinism.
