~The testis in males produce sperms by the process of gametogenesis.
~In testis, the spermatogonia produce sperms by spermatogenesis that begins at puberty. The spermatogonia which is diploid(2n) present on the inner wall of seminiferous tubules multiply by mitotic division and increase in numbers to form primary spermatocytes.
~A primary spermatocyte undergoes meiosis to form two haploid(n) secondary spermatocytes. These then undergo second meiotic division to produce 4 equal, haploid spermatids.
~The spermatids are transformed into spermatozoa by the process of spermiogenensis. after this, the sperm heads become embedded in the sertoli cells from where they gain nourishment.
~ they are finally released from the seminiferous tubules by the process of spermiation.
