What is vitrification in IVF?
What is vitrification for IVF? To embryologists, vitrification is ultra-rapid IVF embryo freezing instead of the traditional slow freezing process. To a science dictionary, vitrification is the process of converting something into a glass-like solid that is free of any crystal formation.
What is vitrification process?
Vitrification is a proven and reliable technology used at U.S. and foreign defense waste processing facilities. The process converts liquid radioactive and chemical waste into a solid, stable glass, eliminating environmental risks. Molten glass is poured into containment vessels where it cools to become solid glass.
How are oocytes cryopreserved?
The procedure of oocyte cryopreservation involves hormonal stimulation, transvaginal retrieval of oocytes from the ovaries, oocyte freezing using vitrification or slow freezing methods, and storage. When ready to conceive, cryopreserved oocytes are thawed and inseminated using standard ART procedures.
When was vitrification introduced?
2006
The slow freezing approach worked well for embryos but not for eggs. The second technique to cryopreserve oocytes is vitrification, which was introduced around 2006 and is much more efficient than its predecessor.
What does the term vitrified mean?
: to convert into glass or a glassy substance by heat and fusion. intransitive verb. : to become vitrified.
What is the purpose of oocyte cryopreservation?
Egg freezing, also known as mature oocyte cryopreservation, is a method used to save women’s ability to get pregnant in the future. Eggs harvested from your ovaries are frozen unfertilized and stored for later use.
Why is vitrification important?
Vitrification is used in disposal and long-term storage of nuclear waste or other hazardous wastes in a method called geomelting. Waste is mixed with glass-forming chemicals in a furnace to form molten glass that then solidifies in canisters, thereby immobilizing the waste.
Is egg freezing successful?
Currently women using their own frozen eggs in treatment have a success rate of 18% (30% with frozen donor eggs), which offers no guarantee of achieving a successful pregnancy and birth.
When to use oocyte vitrification for fertility preservation?
Oocyte vitrification as an efficient option for elective fertility preservation At least 8-10 metaphase II oocytes are necessary to achieve reasonable success. Numbers should be individualized in women >36 years old.
How many babies were born with oocyte vitrification?
Forty babies were born. Conclusion(s): At least 8-10 metaphase II oocytes are necessary to achieve reasonable success. Numbers should be individualized in women >36 years old.
What are the protocols for vitrification of 2PN embryos?
The following protocols and tips are for the vitrification of embryos from 2PN (two-pronuclear zygote) to blastocyst using our Vitrification Freeze Kit, Cryolock or CryoTip or HSV Security Vitrification Straws. ALL PROCEDURES MUST BE PERFORMED AT ROOM TEMPERATURE (22 – 27°C).
How many metaphase II oocytes do you need?
Conclusion(s): At least 8-10 metaphase II oocytes are necessary to achieve reasonable success. Numbers should be individualized in women >36 years old. We suggest encouraging women who are motivated exclusively by a desire to postpone childbearing because of age, to come at younger ages to increase success possibilities.
