Spermatogenesis is the production of sperm in the testes of animals. It begins at puberty and occurs in the epithelial lining of seminiferous tubules. It begins from spermatogonia which are germ cells found around the outer edge of the seminiferous tubules next to the basal lamina. They constantly reproduce by mitosis. Some cells then differentiate into primary spermatocytes which then divide by meiosis to form two secondary spermatocytes. These cells then divide by meiosis themselves to form 4 haploid cells called spermatids. Differentiation occurs producing mature sperm cells which migrate from the tubules to the epididymis where they are stored [1].
