Morphological and hormonal features of an ovine and a caprine intersex.

A caprine and an ovine intersex were examined to compare their morphological and hormonal features in light of their cytogenetic make-up. Both animals, registered as females at birth, developed male-like appearance and behaviour as they approached the age of sexual maturity. Plasma testosterone concentrations in the intersexes were similar to those in adult males of the respective species. Cytogenetic analyses showed male and female cells in the blood while cultures of solid tissue contained only female cells suggesting that both were blood chimeras similar to the bovine freemartins.
