WebSpermatogenesis is a process of gametogenesis in males. In females, oogenesis occurs to form a mature ovum. The male germinal cells or spermatogonia present in seminiferous tubules undergo proliferation by mitotic division. Some of the spermatogonia cells undergo meiotic division and are known as Primary spermatocytes (diploid, 2n=46). WebThe growth period lasts a long time. Duration. From adolescence until death, spermatogenesis occurs every day. From puberty through menopause, oogenesis occurs once a month. Stages. The testis is the origin of all phases of spermatogenesis. The oviduct is the final stage of oogenesis. Release. The testis releases its sperm. The …
