Abstract:

Normal female fertility depends on normally occuring oogenesis and maturity progress. Oogenesis and folliculogenesis are different progresses but occure in a harmony and at the same time. Oogenesis includes the events that take place matur ovum produced from primordial germ cells. Although folliculogenesis includes the stages primordial, primary, secondary, mature (graaf) follicules in the influence of gonadotropines and local growth factors. During oocyte maturation meiosis is destroyed until puberty. Under LH influence it starts again and first meiosis completes before ovulation. Oocyte maturation can be regarded as the process of coming metaphase II from prophase I of oocyte at puberty and can be studied as nuclear and cytoplasmic maturation. Meiosis is completed when fertilization occurs and zygot is formed. In this article oogenesis, folliculogenesis and oocyte maturation process are summerized with related studies and reviews are revised.
