(plural: spermatozoa) [Gr. spermatos - seed, semen; Gr. zoon - animal]. A mature haploid male gamete. Synonym: sperm cell.
The final stage of development of the maturing sperm cell, as it leaves the tubules of the testis the testicular tubules, to mature in the epididymis. Composed of a head (including the acrosome), a midpiece loaded with mitochondria to provide energy, and a tail, or flagellum, for propulsion. Packed into the head of the spermatozoon is a haploid number of chromosomes (there are normally 23, including either an X-chromosome or a Y-chromosome).

A male gamete; also called sperm.
A spermatozoon or spermatozoan (pl. spermatozoa), from the ancient Greek σπÎÏμα (seed) and ζῷον (living being) and more commonly known as a sperm cell, is the haploid cell that is the male gamete. It joins an ovum to form a zygote. A zygote is a single cell, with a complete set of chromosomes, that normally develops into an embryo.
