How long can the eggs be stored?
This question has not yet been answered. Animal studies indicate that, in some instances the viability of frozen eggs may decrease over time. Human egg freezing is relatively new. This is one of the important questions that needs to be answered. Frozen eggs will clearly remain viable for months, and in the case of eggs from younger women, years. Frozen human sperm have been shown to remain viable and capable of producing healthy pregnancies for decades. We encourage all women freezing eggs to place the use of their frozen eggs in the future on a very high priority schedule as we, at this time, simply do not know how long frozen eggs will maintain their ability to produce a healthy pregnancy outcome.
