Detailed explanation-1: -The seminiferous tubules of the testes are the starting point for the process, where spermatogonial stem cells adjacent to the inner tubule wall divide in a centripetal direction-beginning at the walls and proceeding into the innermost part, or lumen-to produce immature sperm. Maturation occurs in the epididymis.
Detailed explanation-2: -Two haploid spermatids (haploid cells) are generated by each secondary spermatocyte, resulting in a total of four spermatids. Spermiogenesis is the final stage of spermatogenesis, and, during this phase, spermatids mature into spermatozoa (sperm cells) (Figure 2.5).
Detailed explanation-3: -spermatogenesis, the origin and development of the sperm cells within the male reproductive organs, the testes. The testes are composed of numerous thin tightly coiled tubules known as the seminiferous tubules; the sperm cells are produced within the walls of the tubules.
