Females are fertile as their ovarian tissue is fully functional. Testicular tissue is abnormal and sterile, but produces high levels of testosterone. This phenomenon also characterizes other talpid species from Europe and North America. To study the origin of this singular reproductive specialization, we examined the gonads of several female specimens belonging to two critical taxa. Although large Japanese moles (\n                    <jats:italic>Mogera wogura<\/jats:italic>\n                    ) posses ovotestes, greater Japanese shrew moles (\n                    <jats:italic>Urotrichus talpoides<\/jats:italic>\n                    ) are characterized by normal ovaries. The results fit parsimoniously with a recent phylogenetic study that places\n                    <jats:italic>Urotrichus<\/jats:italic>\n                    relatively basal in the talpid tree and separate from the American shrew mole. Parsimony reconstruction on alternative phylogenetic hypotheses clearly indicates that reversal(s) must have occurred and suggests that a relatively simple genetic mechanism must be associated with the evolution of female hermaphroditism in moles.\n                    <jats:italic>J.
