抄録

The shape of the infertile seminiferous tubules was examined on the testicular biopsied specimens from the infertile men, using the scanning electron microscope. A parallel study of the same sections was performed by routine light microscopy.<br>The normal seminiferous tubules revealed the shape of the weaving cylinder, but the infertile seminiferous tubules showed the rope strangulated in various places, or the tail-like rope that became gradually slender.<br>These strangulated or slender parts of tubules seem to correspond to the smaller and waste tubules with the thickened tubular walls, found under the light microscope. This thickened wall seems to be the primary changes, which occurred in the infertile testes.<br>The author supposes that these thickened tubular walls suppress the spermatogenesis by the nutritional disturbance, and these strangulations of infertile tubules interfere with the travel of sperms in the tubules by disorganizing “the wave of the seminiferous epithelium” and disturbing the rhythmic peristaltic contractions of the tubules.
