The cortical reaction is important to prevent polyspermy (when multiple sperm fertilize one egg), but it occurs after the acrosomal reaction where the sperm releases enzymes to penetrate the egg's protective layers. If the cortical reaction occurred before the acrosomal reaction was complete, the egg would not have been fully prepared to receive the sperm, and fertilization would not occur.
