Spermatogenesis Spermatogenesis is the production of the male gametes (reproductive or sex cell) otherwise known as sperm. The production of sperm takes place in the seminiferous tubules within the testes and are formed from cells by a type of cell division called mitosis and then meiosis. This process begins at puberty. Spermatogonia cells are made by mitotic division of the primordial germ cell. Mitotic cell division produces diploid cells that are identical to the Parent cell with 46 chromosomes

Describe the cell cycle. Include in your discussion the role cyclins and CDKs play in controlling this cycle. The cell cycle is a process that cells undergo to grow‚ reproduce‚ and divide to make 2 daughter cells. The cell cycle has different stages including G1‚ S‚ G2‚ and the M phase. Also we have the G0 phase. There are checkpoints that control the transitions between the phases of the cell cycle in which the process is regulated by cyclins and cyclin-dependent kinases (CDKs). G1 is known as
