The developmental potential of oocytes that had undergone Germinal Vesicle
Breakdown (GVBD) or reached the MII stage via IVM were assessed by IVF.

Does cryopreservation of ovarian tissue affect the distribution and function of germinal vesicle

breakdown M-I, metaphase-I; Anaph.
It has been observed that the immature germinal vesicle
stage oocytes tolerate the cryopreservation damage more efficiently compared to oocytes at metaphase-II and cumulus compact oocytes are less vulnerable to cryo-injuries compared to their denuded counterpart.
After staying in the prophase for some time, a fully grown oocyte will be triggered by hormones or other stimuli into maturation during which the oocyte will complete germinal vesicle
breakdown (GVBD) and then into metaphase I or II before fertilization (Masui & Clarke 1979).
The size of the mass was measured to the nearest micrometer, and the number of separate entities per mass was assessed using the clearly visible germinal vesicle
as a reference.
