Spermatogenesis
(i) The male germ cells of seminiferous tubules divide mitotically to produce diploid spermatogonia.
(ii) Spermatogonia grow and increase in size and forms primary spermatocyte (2n).
(iii) The primary spermatocytes undergo the first meiotic division and produces two haploid secondary spermatocytes (n).
(iv) Each secondary spermatocyte undergoes the second meiotic division and produces four-equal haploid spermatids.
(v) The spermatids are transformed into spermatozoa (sperms) by the process of spermiogenesis.
(vi) A sperm’s head gets attached to Sertoli cells to draw nourishment and finally released from the seminiferous tubules by the process called spermiation.
