| Abstract: | Among a serie of more than 500 biopsies, the authors show some testicular lesions of difficult interpretation which do not seem to have been reported previously. The electron-microscopical findings are: Contrarily to the uniform thickening of the seminal tube's anhista basal hyalino -esclerosis, in the Klinefelter's syndrome, the anhista shows focal bizarre thickenings, which have been repeteadly observed in the 15 cases studied. Well defined collagen inside the Leydigs's cytoplasm the authors discuss the possible importance of this unique finding in a 28 years old azoospermyc as revealing cellular inmaturity (fibroblastic origin of the interstitial cells). In light microscopy, they discuss the role of the "Hiatus Germinalis", typical of the oligospermies, as related to alterations of the maturation process. |
