Spermatogonium : it is diploid contains 46 chromosomes. 

Primary Spermatocyte (2n): it complete 1st meiotic equal division (reduction) & forms 2 secondary spermatocytes. 

Secondary spermatocytes : it is haploid, undergo the 2nd meiotic div to produce four equal haploid spermatids. 

Spermatids : They transformed into spermatozoa (sperms) by the process called spermiogenesis with the help of FSH. 

Spermiation : After spermiogenesis, sperm heads become embedded in the sertoli cells and finally released from seminiferous tubules by the process of spermiation.
