title: [True XX/XY hermaphrotide, HY antigen positive, without detectable testicular tissue. Observation from birth to the age of ten years (author's transl)].
abstract: A rare modification of true Hermaphroditism is demonstrated in a ten-year-old child we have observed since birth. The cytogenetic analysis revealed a XX/XY-mosaicism. Two kinds of origin are discussed: 1. an ovum with two nuclei was fertilized by two different sperm cells, 2. two heterosexual zygotes fused. -- We could not find tissue of the testes but confirmed the diagnosis of a hermaphroditism by the detection of the HY-antigen and by typical endocrinological findings. Two different cell populations found in erythrocytes and by GPT-isoenzymes indicated a chimerism. By knowledge of these findings, we could help the child to undergo a positive psychological and social development.
