Spermatogonia $ \to $ Spermatocyte $ \to $ Spermatid $ \to $ Spermatozoa Spermatogonia are present on the inside wail of seminiferous tubule multiplied by mitotic division and increase in number. Spermatocytes are some of the spermatogonia, which periodically undergo meiosis. The secondary Spermatocytes undergo the second meiotic division to produce four, equal haptoid spermatids. The spermatids are transformed into spermatozoa (sperm).
