Addition of follicular fluid to oocyte maturation medium can affect cumulus cell function, increase competence of the oocytes to be fertilised and develop to the blastocyst stage and protect the oocyte from heat shock.

Current Opinion in Obstetrics and Gynecology, 1992
Use of donor oocytes is becoming an increasingly important facet of assisted reproductive technology programs. Candidates for donor oocytes include women with premature ovarian failure or severe genetic disorders, women who respond poorly to human menopausal gonadotropin, and women older than 40 years who do not conceive with used of other therapies ...

Cumulus–Oocyte Complex Interactions During Oocyte Maturation
2004In most mammals, the oocyte in the Graafian follicle is surrounded by tightly packed layers of cumulus cells, forming the cumulus-oocyte complex. During the preovulatory period, cumulus cells change from a compact cell mass into a dispersed structure of cells for the synthesis and deposition of a mucoid intercellular matrix, a process referred to as ...

Current Opinion in Obstetrics & Gynecology, 2009
This review summarized the clinical breakthroughs in the human oocyte cryopreservation field in the past 2 years and gave special emphasis on the role of vitrification method. Human oocyte cryopreservation is an attractive strategy to preserve female fertility, as it offers more opportunities to the future destination of the female gametes and also ...

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.

Animal Reproduction Science, 2000
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.
