| Abstract: | Summary An ambisexual male infant showed a normal female karyotype by the leukocyteculture technique in two different occasions. Cultured fibroblasts from the right gonad had also a 46,XX complement. They were Y-chromatin negative. To our surprise, Y-chromatin was observed in 96% of the nuclei in smears from the uncultured gonad. It is emphasized that the examination of the uncultured gonad by the quinacrine technique is mandatory in the study of  XX males . |
