Sperm formation takes place in testes. The formation of sperms from immature germ cells or spermatogonia is called spermatogenesis. Spermatogonia (diploid) divide mitotically, grow in number and give rise to primary spermatocytes (diploid). Primary spermatocytes undergo the first meiotic division to produce secondary spermatocytes (haploid). The second meiotic division in the secondary spermatocytes leads to the formation of spermatids (haploid). Spermatids mature and transform into motile spermatozoa or sperms (haploid) by the process called spermiogenesis.
