Abstract
Fourteen patients with sexual abnormalities have been investigated for their chromosomal conditions. Eleven of the 14 cases had an apparently normal karyotype, 2 patients exhibited sex-chromosome mosaicism of the XY/XO, and one was XX/XXY mosaic. One of the two XY/XO mosaics is probably fertile.
The importance of chromosomal studies on more than one tissues and a detailed histological examination of the gonads in cases with sexual abnormalities in general and suspected mosaicism in particular, has been emphasized.
