Abstract
Studies with hamster gametes in vitro have shown that the microvilli of the vitellus wrap around the head of the sperm and fuse with its plasma membrane in the postacrosomal region (Yanagimachi and Noda, 1972). The role of the postacrosomal plasma membrane in initiating fusion between mammalian gametes is in striking contrast to gamete fusion in marine invertebrates in which initial contact with the egg membranes is made by an apical process extending from the inner acrosomal membrane (Colwin and Colwin, 1967; Epel, 1975; Summers et al., 1975).
