A spermatozoon (pronounced /ˌspɜːrmætəˈzoʊən/,

Alternate spelling spermatozoön;

Plural spermatozoa;

From Ancient Greek: σπέρμα (“seed”) and Ancient Greek: ζῷον (“living being”))

Is a motile sperm cell, or moving form of the haploid cell that is the male gamete.

A spermatozoon 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.)
