Answer: The acrosome of the sperm contains enzymes necessary for the penetration of the egg.

Capacitation process occurs to remove the glycoproteins found on the surface of the acrosome and this process takes place in the vagina. Without the process of capacitation the fertilisation of the egg by the sperm would not be possible.
