Both were also photographed 1 min after insemination during normal fertilization (Sato and Osa- nai. 1983). However, in normal fertilization, the sperm attachment step is rather inseparable, because it is fol- lowed quickly by the acrosome reaction. We could sepa- rate the sperm attachment step in Ca-free medium, in which the acrosome reaction was prevented. Sperm attachment occurred at only the head-tip of.
