Write note on : Spermatogenesis
- In testis, immaure male germ cell produce sperms by spermatogenesis.
- The spermatogonia present in the inside wall of seminiferous tubule multiply by mitotic division.
- Some spermatogonium called primary spermatocyte undergo meiosis,
- A primary spermatocyte completes first meiotic division to give rise to the secondary spermatocyte.
- After undergoing second meiotic division, spermatids are produced.
- By spermiogenesis, these spermatids form Spermatozoa.
