Answer:
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells.
Four spermatids: haploid (N) / 23
Primary spermatocyte: diploid (2N) / 46
Two secondary spermatocytes: haploid (N) / 23
Spermatogonium (types Ad, Ap and B): diploid (2N) / 46
Four functional spermatozoids: haploid (N) / 23
