[A] In human males, the primordial germ cells divide mitotically and produce spermatogonia. Some of the spermatogonia grow into large primary spermatocytes. Each primary spermatocytes undergoes first maturation division which is a reductional (meiotic) one. Thus, the primary spermatocytes divides into two haploid daughter cells called secondary spermatocytes. Each secondary spermatocyte now undergoes second maturation division which is a mitotic one. Thus, each secondary spermatocytes gives rise to two sapermatids that undergo transformation to form two sperms. Overall, two secondary spermatocytes give rise to four sperms
