Summary Introduction
Introduction:
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.

An ¬¬¬¬ _, or fallopian tube, extends from the __________ toward a funnel-like opening at each ovary. Upon _____________ , cilia on the epithelial lining of the oviduct help collect the egg by drawing fluid from the body cavity into the oviduct.

Spermatogenesis is the final stage of reproductive cell division by which there is the development of haploid spermatids into sperm.
