Sperm is the male reproductive cells produced by the seminiferous tubules of the testes. A human sperm has likely three parts, head, mid-piece, and tail. The head part contains a nucleus or a sac of an enzyme that covered the nucleus, called the acrosome. Mid-piece contains the mitochondria, which provide the energy for the movement of the tail. And the end part of the sperm is a tail, the whip-like movements of the tail propel the sperm through the female reproductive tract.
