- W1987766730 abstract "This electron microscope study demonstrates changes leading to formation of binary spermatozoa. Spermatids contain Golgi complex, mitochondria, centrioles, microtubules, and ribosomes. Spermiogenesis is characterized by migration of nucleus, Golgi complex, and centrioles to one pole of the cell. The Golgi complex gives rise to an acrosomal vesicle. As spermiogenesis proceeds, there is an increase in phagocytosis and numbers of intracellular multilaminar, multivesicular, and granular bodies leading to cytoplasmic sloughing. Many phagocytic vacuoles fuse and undermine developing, crescent-shaped spermatozoa. During spermiogenesis the acrosome and centrioles fuse with nuclear chromatin to lose their morphological identities. Mature crescent-shaped spermatozoa are found juxtaposed on their concave surfaces. Sperm are characterized by an electron dense nucleus, lack of mitochondria, and an identifiable motile appendage. These observations are compared to earlier studies, and it is concluded that mature spermatozoa of Polydesmus sp. are not binucleate, but adhere at their concave surfaces as binary appearing structures." @default.
