spermatogonia, spermatocyte, spermatid, spermatozoa

Explanation:

In testis, the immature male germ cells or spermatogonia (2n) multiply by mitotic divide and increase in number.

The secondary spermatocytes undergo second meiotic division to produce spermatid which are transformed into spermatozoa (sperms) by the process called spermiogenesis.
