Webwww.kgmu.org WebThey are 2 – 3.5 cm long. Within the ovaries two important processes occur, folliculogenesis and oogenesis. Folliculogenesis is the process of developing the ovarian follicle while oogenesis is development of the mature ova. As explained later, these two processes occur simultaneously and are intimately associated with each other.

The process of oogenesis starts pre-natally, i.e. before the birth of the female child. It begins about 8-20 weeks after the fetus has begun to grow and goes on until the birth of the child.
