Oogenesis finds impetus and purpose in casting scientific perspective towards this unique cell for the benefit of scientists and assisted reproductive technology ... WebINTRODUCTION. Oocyte maturation is the terminal process of oogenesis during which fully grown oocytes initiate meiotic divisions and become fertilizable (see [11] for review). The onset of oocyte maturation is signalled by breakdown of the oocyte nucleus, the germinal vesicle (GV).

It cannot be neglected that oogenesis is a precisely orchestrated process, during which the oogonia and primary oocytes are formed, and RNA synthesis takes place. These RNAs are crucial for oocyte growth and maturation. WebThe process of oogenesis culminates in steroid-induced oocyte maturation to produce the fertilizable egg.
