Dynamic changes in the cytoskeleton during human spermiogenesis

Dynamic cytoskeletal movement was observed during human spermiogenesis. Cytoskeletal rearrangements in the Sb2 period appear to play important roles in the morphologic changes that occur during human spermiogenesis. Studies of the cytoskeletal system during spermiogenesis may help identify some causes of male infertility (e.g., teratozoospermia, maturation arrest).
