The Sperm cell is known as the male reproductive cell. The word sperm comes form the Greek word for seed, 'sperma'. Sperm cells contain 23 chromosomes and are known as a haploid cell, since it contains half of its parents' chromosomes. The Sperm cell consists of two structures: the head which is 5 µm long and 3 µm wide and a flagellum that is 50 µm long. The structure was first observed in 1677 under a microscope.

It can be either motile or non-motile. It is considered motile (or "spermatozoon") when the sperm has the single flagellum, which moves in a whip-like manner and it goes to the egg. While the non motile sperm do not have the flagellum and it is called "spermatium"[1].
