Abstract

An ambisexual male infant showed a normal female karyotype by the leukocyte culture 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".

摘要

一名两性男婴在两次不同的检测中，通过白细胞培养技术显示出正常的女性核型。来自右侧性腺的培养成纤维细胞也具有46, XX核型。它们的Y染色质呈阴性。令我们惊讶的是，在未经培养的性腺涂片的96%的细胞核中观察到了Y染色质。需要强调的是，在“XX男性”的研究中，采用喹吖因技术对未经培养的性腺进行检查是必不可少的。
