The process of spermatozoa development from germ cells is called spermatogenesis and it occurs in the seminiferous tubules of the testis. The germ cells move towards the lumen as they mature. There are 4 phases of spermatogenesis: 1. Mitosis of spermatogonia-primary spermatocytes are produced 2. First meiosis - form the primary spermatocytes to the formation of secondary spermatocytes 3. Second meiosis-formation of the spermatids 4. Spermiogenesis-up to the completed sperm cells.
