Article

Summary

Sperm development inHymenolepis diminuta was studied by light and electron microscopy and cytochemical techniques. Spermatogenesis involves a complex series of events in which syncytia are formed. At the light-microscope level, spermatozoa formation was first observed as a ‘threading out’ of the peripheral cytoplasm of the 64-nuclear syncytium. Electronmicroscopic studies confirmed and expanded the light-microscopic observations. Cytochemical and morphological observations demonstrated that mature spermatozoa ofHymenolepis diminuta lack mitochondria. Glycogen was present only in mature spermatozoa and only in the form of β-particles. Acid phosphatase was demonstrated in the axoneme of mature spermatozoa.
