Abstract
The presence of oblique striations on the cortex of the dense fibers of the rat spermatozoon is confirmed. They have a main periodicity of approximately 40 nm and a secondary one of about 20 nm. Disruption of spermatozoa by Triton X-100 and dithiothreitol and fixation in glutaraldehyde do not affect the pattern. The dense fibers cortex appears to consist of globular substructure units with a diameter of about 19 nm.This publication has 1 reference indexed in Scilit:
