Fine Structure of Spermatogenesis in Klinefelter's Syndrome

Abstract

The case of a patient with clinical evidence of Klinefelter's syndrome, positive sex chromatin and a karyotype of 47/XXY is presented. Testicular biopsy showed a histological picture characteristic of Klinefelter's syndrome and areas of spermatogenesis were encountered in some tubules. The fine structure of the testes in the case was studied by electron microscopy and the findings are reported and discussed.
