Gametogenesis is the process of production of gametes. In males, it is spermatogenesis and in females it is oogenesis. The cells in the germline that undergo meiosis, primary spermatocytes or primary oocytes, are derived from the zygote by a long series of mitosis before the onset of the two meiotic cycles to form the mature gametes. Testosterone is an androgen that plays an important role in the formation and release of sperm from the seminiferous tubules.
