At stage 7 of oogenesis, posterior follicle cells send a signal back to the oocyte that polarizes the oocyte's MT cytoskeleton, a prerequisite both for the migration of the oocyte nucleus to a point along the oocyte's anterior cortex [31], and the transport of bicoid, oskar and other mRNA that encode embryonic patterning determinants to specific ends of the oocyte [2], [4].

The outcome of the repolarization results in the disassembly of the MTOC at the posterior, nucleation of microtubules anteriorly and subsequent migration of the oocyte nucleus to an antero-lateral position.

How MTs are reorganized at this stage remains controversial, but a recent study has suggested that anterior migration of the oocyte nucleus during stage 7 is due to its being pushed by the posterior-lying centrosome (Zhao et al. 2012).

For example, Yamanishi et al. [5] succeeded in enucleation of oocyte by cutting the surface of the oocyte.

Human ovarian reserve is determined by the size of oocyte pool at birth and an age-related decline in oocyte numbers thereafter.
