A [[flagellum|flagellated]] cell that serves as the male gamete in fertilisation. Sperm are produced in large quantities by males in their [[testes]] and are stored in the [[epididymis]]. Their part in human [[reproduction]] is amongst the most amazing feats of nature due to the intense and exhausting journey sperm make up the vagina, [[uterus]] and [[fallopian tubes]] in order to reach the [[ovum]] and fertilise it.

A sperm cell ('''spermatozoon''', pl. '''spermatozoa''') is a [[flagellum|flagellated]] cell that serves as the male gamete in fertilisation. Spermatozoa are produced in large quantities by males in the seminiferous tubules of the [[testes]], and are stored in the [[epididymis]]. Their part in human [[reproduction]] is amongst the most amazing feats of nature due to the intense and exhausting journey sperm make in travelling up the cervix, [[uterus]] and (in some cases) [[fallopian tubes]], in order to reach the [[ovum]] and fertilise it. They are guided to it partly by a hormone released by the ovum itself.
