[Familial true hermaphroditism (apropos of 2 families)]

The authors report the cases of two new families of true hermaphroditism (4 cases) defined by the coexistence of both testicular and ovarian tissues. Exceptionally the disease presents a familial recurrence: only 8 families have been reported in the literature. When the study is done HY antigen is always increased in patients with true hermaphroditism and sometimes slightly increased in their mothers who are phenotypically normal.
