Oogenesis is the process of meiosis in female organisms from an oogonium to a primary oocyte, to a secondary oocyte, and then to an ovum. Spermatogenesis is a similar process of forming sperm by meiosis in males.

Oogenesis - Wikipedia, the free encyclopedia
Oogenesis or oögenesis (pronounced /ˌoʊ.əˈdʒɛnɨsɪs/ )is the creation of an ovum (egg cell). It is the female process of gametogenesis. It involves the various stages of immature ova. In mamma...

Oogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the gamete formed by oogenesis contains all the materials needed to initiate and maintain metabolism and development.

Genes involved in oogenesis ... Hundreds of genes participate in oogenesis, the building of the egg. The egg is a highly structured chamber. Its RNA, DNA and proteins do not roam freely, but rather are directed and controlled by the egg's dorsoventral polarity and anterior-posterior axis.

7.2 Spermatogenesis and Oogenesis ... First of all, oogenesis only leads to the production of one final ovum, or egg cell, from each primary oocyte (in contrast to the four sperm that are generated from every spermatogonium). Of the four daughter cells that are produced when the primary oocyte divides meiotically,

A major difference between spermatogenesis and oogenesis is that spermatogenesis occurs after meiosis, whereas differentiation of the female gamete may occur early in meiosis See Figs. 2.1 and 2.2. (Unless noted otherwise, all figure references are to Browder et al., 1991.
