Answer» The process of formation of female gametes is called oogenesis. Process: During embryonic stage millions of gametes mother cells are formed (oogonia). This is covered by primary follicles. At the attainment of puberty, about 60,000 + 80,000 primary follicles are left in each overy. Now it gets surrounded by secondary follicles. Then formation of tertiary follicle takes place. Tertiary follicle matures into Graafian follicle – Tertiary Follicle ruptures to release secondary ooclyle by the process called ovulation.
