Spermatozoa are a mature male germ cell, which fertilizes the oocyte in sexual reproduction and contains the genetic information for the zygote from the male. Spermatozoa, formed in the seminiferous tubules, are derived from spermatogonia, which first develop into spermatocytes; these in turn produce spermatids by meiosis, which then differentiate into spermatozoa.
Mature human spermatozoa are 60 µm long, actively motile, divided into 3 main regions: head, neck and tail. Thespermatozoa have to go through several temporal maturation steps in a series of different locations in order to be capable of penetrating into the oocyte.
