Waves and stages of the cycle of the seminiferous epithelium were easily and economically demonstrated when sections of the testicle were treated with periodic acid Schiff reagent (PAS) then counterstained with hematoxylin. This combination aided in the visualization of the head cap and acrosomic system, all of which help to identify the various stages in the cycle of the seminiferous epithelium. Spermatogenic cells demonstrate with scanning and transmission electron microscopy, though more time consuming and using much more complex and expensive processes in preparation, reviewed a greater depth of field and elaborated more detail in an ultrastructural level.
