Please can we go over the process of spermatogenesis?

Of course. Spermatogenesis takes place in the seminiferous tubules of the testis. The germinal epithelium cells, which are in the wall of the seminiferous tubule, first differentiate into diploid spermatogonia. These spermatogonia divide my MITOSIS to produce primary spermatocytes, which are still diploid. The primary spermatocytes then divide by MEIOSIS, to become HAPLOID secondary spermatocytes. Then, the secondary spermatocytes undergo a second MEIOTIC division, to form spermatids. These spermatids differentiate into mature spermatozoa (also known as sperm.)
