Explanation : Spermatogenesis is the process of the production of sperms from the immature male germ cells. It starts at puberty and usually continues uninterrupted until death, although a slight decrease in the quantity of sperm is seen with the increase in age.
· They stop undergoing mitosis, grow and become primary spermatocytes (2N). Each primary spermatocyte undergoes meiosis to form two equal haploid secondary spermatocytes (N).
· Each secondary spermatocyte then undergoes a second meiotic division to form four equal haploid cells called spermatids (N).
· Spermatids receive nourishment to form sperms by the process called spermiogenesis.
