Spermatogenesis is the process of sperm cell development, occurring in the seminiferous tubules of the testes. It involves several stages, starting with spermatogonia, which undergo mitosis to form primary spermatocytes. These then undergo meiosis to produce secondary spermatocytes and finally spermatids. The spermatids undergo a series of morphological changes to become mature spermatozoa, ready for ejaculation and potential fertilization.
