Steps and can be seen as
A-Sperm passes through corona radiate, B-Acrosome reaction, releasing lysing enzyme, C-Sperm passes through pellucida and reaches oolemma. D-Sperm and egg plasma membranes fuse, enabling the sperm contents to enter egg. E-Cortical reaction, releasing enzymes to harden zona pellucida
