Detailed explanation-1: -As mentioned above, spermatogenesis is the process by which sperm cell production occurs; the germ cells give rise to the haploid spermatozoa. Sperm production takes place inside the seminiferous tubules, which is a convoluted cluster of tubes located inside the testes.

Detailed explanation-2: -The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.

Detailed explanation-3: -The final phase of spermatogenesis is the maturation of spermatids from round to elongated spermatids and then to mature spermatozoa; this process, known as spermiogenesis, is followed by release of spermatozoa into the lumen of seminiferous tubules (spermiation).

Detailed explanation-4: -The spermatogonium(2n) undergoes mitosis to form primary spermatocytes(n). The primary spermatocytes divide meiotically to form the secondary spermatocyte (n) which further divide to from the spermatids(n). These spermatids mature to form the sperms(n). The ploidy of secondary spermatocytes is n(haploid).
