It is induced by substances from the egg investments and releases enzymes involved in penetration of the ovum.crosome reaction. fusion of the outer acrosomal membrane with the sperm plasma membrane, and the breakdown of the fused complex, after the attachment of the spermatozoon to the zona pellucida.
