<P> It is commonly believed that , when oocytogenesis is complete , no additional primary oocytes are created , in contrast to the male process of spermatogenesis , where gametocytes are continuously created . In other words , primary oocytes reach their maximum development at ~ 20 weeks of gestational age , when approximately seven million primary oocytes have been created ; however , at birth , this number has already been reduced to approximately 1 - 2 million . </P>
