![]() Thus four sperms are formed from one spermatogonium. The spermatozoa are later on known as sperms. The transformation of spermatids into spermatozoa is called spermiogenesis or spermateliosis. ![]() (ii) Formation of Spermatozoa from Spermatids (Spermatogenesis): Both secondary spermatocytes now undergo second maturation division which is an ordinary mitotic division to form, four haploid spermatids, by each primary spermatocyte. ![]() Hence, the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. The first maturation division is reductional or meiotic. Each primary spermatocyte undergoes two successive divisions, called maturation divisions.
