Egg Freezing for Future Cycles and Fertility Preservation
The purpose of egg cryopreservation (freezing) is to preserve unfertilized eggs for fertilization using IVF at a future date. Eggs retain their "fertility capacity" present at the time of harvesting. If a woman freezes her eggs at 25 years of age, she can use them when she is older. Most experts believe that the eggs will still have the fertilization capacity that they did when they were frozen.
Egg freezing can be performed prior to chemotherapy, radiation, or surgery that might render a woman infertile by damaging her eggs or ovaries. Egg freezing is also used by women who delay child bearing because they are pursuing a career, have not found a partner, and for other reasons.
Egg freezing can also be used for freezing so that multiple recipient couples could use eggs from the same egg donor. Their is no need for endometrial synchronization and preparation of the female recipients at the same time the eggs are retrieved.
Freezing extra eggs when a large number of eggs are retrieved from an egg donor allows couples the option of donating unused and unfertilized eggs to other infertile couples. They also retain the option of using the eggs themselves if their initial in-vitro fertilization (IVF) fresh cycle does not result in a pregnancy, or when additional pregnancy(s) are desired at a later time. The egg freezing option eliminates the need to fertilize too many eggs that may result in extra embryos that may not be needed.
Our fertility specialists have followed egg freezing research closely over the past decade. Dr. Blauer was involved in research using frozen donor eggs in 1998. The first embryo Dr Blauer transferred using frozen eggs was performed in 2005 while in Virginia. Since then, the program has achieved a number of delivered pregnancies with the use of frozen eggs. The first delivered pregnancy using frozen eggs in Utah was performed at Reproductive Care Center in 2009.
There is an easy to use calculator that predicts the chances of success based upon the number of eggs frozen/thawed, the number of eggs injected with frozen sperm (ICSI), and the number of embryos transferred. See Innovation Fertility Preservation and IVF.
