The sperm is divisible into 3 parts - the head, midpiece and tail. The head consists of acrosome which contains hyaluronidase and proteolytic enzymes, which help in penetrating the ovum during fertilisation. Along with the acrosome the head of the sperm also consists of a haploid nucleus and centrioles. The midpiece of the sperm has mitochondria which produce the energy necessary for sperm motility. The tail is mainly involved in providing motility to the spermatozoon, and propels it forward.
