Related QuestionsHow are frozen embryos stored and monitored?
Pacific Fertility CenterThe air that we breathe contains a gas called nitrogen. This gas makes up about 78% of the air around us. If nitrogen gas is cooled, it becomes liquid at –1960C. This liquid is very stable and easy to work with. In the laboratory we have large tanks filled with liquid nitrogen in which we store frozen embryos. Each tank, actually called a DEWAR, is in many ways like a large thermos flask. It is vacuum lined and has a narrow opening to slow the evaporation of the nitrogen.

Related QuestionsHow long can embryos be stored?
Pacific Fertility CenterNo one knows what the maximum storage period might be. Procedures for human embryo freezing were developed in 1984 and only went into widespread use in the late 1980's. This means that the longest time a human embryo has been stored is 12-15 years, and typically, patients that have left embryos in storage for this long are not coming back for them. Some patients have come back after 10-12 years and the embryos have been thawed successfully.
Related QuestionsHow long can embryos be frozen and still be viable?
EMBRYO DONATION - Facts About EmbryosTheoretically, embryos may be frozen indefinitely, as no biological activity takes place during cryopreservation. In practice, it is unknown how long they can remain viable. The first frozen embryo transfers resulting in live birth took place in the mid-eighties. Since then, embryos frozen as long as 12 years have resulted in successful pregnancy. Freezing and thawing protocols continue to improve, making it possible that embryos frozen more recently may have better outcomes.
Related QuestionsHow are embryos frozen?
Pacific Fertility CenterEmbryos can be frozen at different times after fertilization. Most typically, embryos are frozen 1, 3 or 5 days after the sperm and egg were put together. Freezing is a stressful process for an embryo, and only embryos that are growing well in the laboratory will tolerate the freezing procedure. Before an embryo can be frozen, all the water that it contains must be removed.

How are embryos frozen and stored after an IVF cycle?
EMBRYO DONATION - Facts About EmbryosVery carefully! During the freezing process, even under the stringent protocols used by IVF labs, embryos must survive the dangers of ice formation, extreme changes in temperature, pH and the concentration of electrolyte in their environment, as well as transmembrane water movement. The cells of embryos, like other living tissue, contain water. Water forms sharp ice crystals and expands as it freezes, which would cause the embryo to burst if it were not removed first.
Related QuestionsCan my frozen embryos survive storage?
Frequently Asked Questions with Dr. Charles MPL on IVFThe quality of your embryos is the main determinant for survival and implantation. Expected survival is about eighty per cent. Quality of embryos is determined largely by the quality of your eggs (oocytes).
Related QuestionsWhat is the current supply of frozen embryos?
Embryos aliveA:At present, there are about 400,000 frozen embryos stored in fertility clinics around the country. However, only half of those embryos are expected to survive upon thawing (grade one and two embryos). Unfortunately, many embryo donors do not want to make their embryos available for adoption. Like traditional adoptions, there is a waiting list to adopt the embryos. Once again, demand is greater than the supply.
Related QuestionsCan embryos be frozen more than once?
EMBRYO DONATION - Facts About EmbryosYes. Sometimes when a large quantity of embryos are frozen at an early stage of development (2PN), all or a good number of them will be thawed and incubated. As with a fresh transfer, the best quality embryos will be selected for transfer and the remainders re-frozen.

Why weren't of my spare embryos all frozen?
WestMead Fertility Centre | Frequently Asked QuestionsFertilisation of an egg does not always produce a perfect embryo. Even at the very early stages it is possible to see differences in embryo growth. Embryos which do not have a normal shape and appearance may not survive the processes of freezing and later thawing. These embryos are also unlikely to cause a pregnancy. Specialist embryologists can tell by looking at an embryo if it has any chance of surviving or no chance.
Related QuestionsWhat are the costs for keeping embryos in frozen storage?
Pacific Fertility CenterThe costs to Pacific Fertility Center are significant. Most of the cost is accounted for by the manpower required to maintain the tanks. Embryologists receive special training in handling liquid nitrogen and maintaining the frozen embryo bank. Although nitrogen liquid is relatively stable, it can cause severe frostbite, rapid suffocation and death if mishandled.

Related QuestionsWill frozen embryos be as likely to produce a pregnancy as fresh embryos after they are thawed?
EMBRYO DONATION - Facts About EmbryosThe success rates for frozen embryo transfers are usually lower than those for fresh embryo transfers. This may be due to damage to the embryos during freezing, but may also be due to the fact that the embryos evaluated to be of the highest quality in the batch are usually transferred fresh. In addition, more patients undergoing a frozen embryo transfer have had a failed cycle than those undergoing a fresh transfer.

Related QuestionsWhat are my chances of success using donor frozen embryos?
Understanding Embryo DonationA number of factors determine the success rates of frozen embryo transfers. These include the quality of the embryos that are frozen, the stage of the embryos when they were frozen, and how well the embryos survive the thawing process. Depending on the stage the embryos were in when they were frozen (at fertilization, day 3 or day 5), between 50-80% of the frozen embryos typically survive the thawing process and continue dividing.

FAQ - In Vitro Fertilization, Artificial Insemination, Ferti...with in vitro fertilization involving fresh embryos, the age of the egg provider is the single most important predictor of outcome. For embryos frozen on Day 3, approximately 70% will survive the freeze/thaw process. This may be higher for embryos frozen on Day 5 (blastocysts).
