| Abstract: | Cytochalasin B inhibits the penetration of sperm nuclei into Urechis eggs without inhibiting sperm-induced egg activation. The acrosome reaction appears normal, and plasma membranes of the acrosomal tubule and egg become closely apposed. It is uncertain whether or not the drug blocks fusion of these membranes; however, sperm penetration cone formation is inhibited. |
