Spermatogenesis and the structure of the mature spermatozoon ofTrilocularia acanthiaevulgaris have been studied by light microscopic histochemistry and transmission and scanning electron microscopy. The primary spermatogonia occupy the periphery of the testis and undergo four mitotic divisions; incomplete cytokinesis results in two secondary, four tertiary and eight quaternary spermatogonia and sixteen primary spermatocytes. The quaternary spermatogonia and successive stages develop in a… CONTINUE READING
