<P> In mammals the acrosome reaction releases hyaluronidase and acrosin ; their role in fertilization is not yet clear . The acrosomal reaction does not begin until the sperm comes into contact with the oocyte 's zona pellucida . Upon coming into contact with the zona pellucida , the acrosomal enzymes begin to dissolve and the actin filament comes into contact with the zona pellucida . Once the two meet , a calcium influx occurs , causing a signaling cascade . The cortical granules inside the oocyte then fuse to the outer membrane and a transient fast block reaction occurs . </P>
