Despite early success with sperm and embryo cryopreservation, human oocyte cryopreservation has met with limited success both in terms of survival and subsequent fertilization. However, compared with embryo cryopreservation, oocyte freezing has great potential for eliminating the ethical and legal problems of embryo storage.

The penetration of the zona pellucida is a crucial step during fertilization. Spermatozoa that are unable to recognize and bind to the zona pellucida glycoproteins or respond to the zona pellucida by undergoing the acrosome reaction fail to fertilize the egg.

This Committee Opinion concludes that donors be advised on the number of cycles/donations that a given oocyte donor may undergo. Although existing data cannot permit conclusive recommendations, a concern for the issues of safety and well-being of oocyte donors warrants consideration.

[Oocyte maturation: can oocyte competence be defined?].
Journal de gynecologie, obstetrique et biologie de la reproduction, 2006Oocyte competence is acquired throughout oogenesis, via the interaction with somatic cells. The ability to reinitiate the meiotic process and undergo preimplantation development is progressively determined during the antral phase. It is well-known that these changes involve the nuclear and cytoplasmic compartments, respectively, but the underlying ...

The dialog between oocyte and cumulus cells brings a major contribution for oocyte meiotic and developmental competence. On the one hand, the oocyte will modulate follicle growth through specific gene expression (Figalpha, GDF-9, BMP15) as well as its meiosis (GPR3 et PDE3A).
