About Translations. This page introduces spermatogenesis the development of spermatozoa, the male haploid gamete cell. In humans at puberty, spermatozoa are produced by spermatogonia meiosis in the seminiferous tubules of the testis male gonad. A second process of spermiogenesis leads to change in cellular organisation and shape before release into the central lumen of the seminiferous tubule. This overall process has been variously divided into specific identifiable stages in different species: 6 in human, 12 in mouse, and 14 in rat.
