Ultrastructural studies on the sertoli and spermatids in the bandicoot and ram during the movement of mature spermatids into the lumen of the seminiferous tubule

Abstract

In the terminal stages of spermiogenesis in the bandicoot, branches of Seroli cell cytoplasm are seen to invade the lateral aspects of spermatids. Some of the ivadeing branches pursue a course along the border of various parts of the spermatid tail; others penetrate into the Cytopasmic canal. One function of the invading branches is thus partially to dissect the future spermatozoon from sulphur spermatid cytoplasm.
