WebbThe process of oogenesis starts in the fetal ovaries with the development of oogonia from primordial germ cells (PGCs). Oogonia are formed during fetal development (in the process called oocytogenesis), and divide via mitosis, much like spermatogonia in the testis. WebbIt occurs in three phases i.e., Multiplication phase, growth phase and maturation phase. In the multiplication phase, some cells of the germinal epithelium of ovary function as primary germ cells and are called oogonia, which multiply by repeated mitotic division and become primary oocytes when cell division ceases.
WebbDuring foetal development, as the process of oogenesis begins, few cells of the germinal epithelium enlarge and undergo repeated mitotic divisions to form a group of germ cells known as oogonia or egg mother cells. Around two to eight million oogonia are formed in the foetal ovary and no more oogonia is added or formed in the ovary after birth.

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis.
