Vitrification of Oocytes and Embryos
Currently, controlled ovarian hyperstimulation protocols commonly provide embryos in excess of those needed for fresh transfer. Therefore, techniques have been developed to store these surplus embryos in liquid nitrogen (referred to as cryopreservation) for an indefinite period of time without significant compromise of their quality. Based on data from the Centers for Disease Control and Preven...
متن کاملCryopreservation of Mammalian Embryos by Vitrification
protectant for spermatozoa41) led to research on cryopreservation of mammalian embryos. In the past quarter of a century since the first successful cryopreservation of mouse embryos58,60), basic and applied research has resulted in the cryopreservation of embryos of many mammalian species. Improvements have been made in nearly all steps of the cryopreservation process, resulting in considerable...
متن کاملA critical appraisal of cryopreservation (slow cooling versus vitrification) of human oocytes and embryos.
BACKGROUND Vitrification is now a commonly applied technique for cryopreservation in assisted reproductive technology (ART) replacing, in many cases, conventional slow cooling methodology. This review examines evidence relevant to comparison of the two approaches applied to human oocytes and embryos at different developmental stages. METHODS Critical review of the published literature using P...
متن کاملVitrification of Mouse and Sheep Embryos
Vitrification is a method of storing cells in a supercooled state, and is particularly useful for the cryostorage of embryos. With a supply of liquid nitrogen and simple apparatus, vitrification in the field situation is feasible and is potentially simpler and cheaper than the standard freezing processes. However, survival of embryos after vitrification has not yet proved better than after free...
متن کاملTerminology associated with vitrification and other cryopreservation procedures for oocytes and embryos.
Over the past 30 years many cryopreservation procedures have been applied to oocytes, embryos, sperm, ovarian and testicular tissue. Over this time many, often specialized, terms have been developed for all aspects of these procedures. This can make it difficult for readers who are not familiar with the terminology or protocols to compare and evaluate different procedures. This paper describes ...
