Vedclass · Answer

(D) Polyspermy refers to the entry of more than one sperm into an ovum during fertilization. To prevent this,the ovum undergoes specific changes immediately after the first sperm enters. The cortical granules present beneath the plasma membrane of the ovum release their contents into the perivitelline space. These contents harden the zona pellucida,forming a fertilization membrane. This membrane acts as a physical barrier that prevents any other sperm from entering the ovum,thereby ensuring monospermy.

Polyspermy is generally prevented by which of the following?
