Question

The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is

Accepted Answer

In spermatogenesis during growth phase, some spermatogonia either due to growth or due to food storage become 2 or 3 times larger of their original size and are known as primary sper matocytes, which undergo meiosis-I and as a result 2 haploid secondary spermatocytes are formed. Fuether, meiosis-II takes place that result in the formation of 4-spermatids. Then these round, non-motile and haploid spermatiatids are transformed into thread-like motile, haploid sperms (four).
