Chromosomal anomalies and testicular ultrastructure.

At the Clinic of Urology, Postgraduate Medical School, Budapest, between 1976 and 1980, 1043 andrological examinations were carried out. Among 62 couples, cytogenetic examinations were performed, too. Altogether 12 chromosome anomalies were developed, amongst them 5 Klinefelter's syndromes. The ultrastructure of the testicles of them, plus of a male patient with the dimorphism of chromosome E 16, is discussed.
