The process of fusion of the sperm and the ovum is known as fertilization. During fertilization the sperm induces changes in the zona pellucida and blocks the entry of other sperms. This ensures that only one sperm fertilizers an ovum.The enzymatic secretions of the acrosome help the sperm enter the cytoplasm of the ovum. This causes the completion of meiotic division of the secondary oocyte, resulting in the formation of a haploid ovum and a secondary polar body. Then, the haploid sperm nucleus fuses with the haploid nuclues of the ovum to form a diploid zygote.
