Secretion of Acrosome:
When the sperm reach close to the ovum, they release enzymes stored in the acrosome. These enzymes help in breaking down the protective layer surrounding the ovum called the zona pellucida.
Penetration of Zona Pellucida:
Only one sperm is able to successfully penetrate the zona pellucida and reach the cytoplasm of the ovum. This sperm then fuses with the ovum, leading to fertilization.
Loss of Tails:
Once the sperm has penetrated the zona pellucida and fused with the ovum, it loses its tail. This prevents other sperm from fertilizing the ovum and ensures that only one sperm is involved in the fertilization process.
Prevention of Other Sperm:
The cells of the corona radiata, which surround the ovum, help trap and prevent other sperm from reaching the ovum after one sperm has successfully entered the cytoplasm.
In summary, during fertilization, the secretion of acrosome helps one sperm enter the cytoplasm of the ovum by breaking down the zona pellucida. This prevents other sperm from fertilizing the ovum, and only one sperm is involved in the process of fertilization.
