Metric to Ask Any Egg Bank

When you are choosing an egg bank, one clinical number matters more than any other: the frozen egg survival rate.

This is the percentage of frozen eggs that remain viable after the thaw. It is the foundation of every donor egg IVF cycle because an egg that does not survive the thaw is an opportunity that does not come back.

“An egg that does not survive the thaw is an opportunity that does not come back. This is the number that defines the floor of your cycle.”

Find Your Closest Egg Donor Match in Minutes

Freezing and thawing a human egg requires precision across the entire vitrification process. The quality of the egg at the point of freezing, the consistency of the freeze, storage conditions, and the thaw protocol all affect viability.
The industry average is approximately 80–85%. A 92.2% rate reflects a clinical standard that compounds across the entire egg donor selection and laboratory process.
Every percentage point above the industry average represents real eggs that remain viable — and real chances that otherwise would not have been available to the intended parent. Over the course of a cohort of frozen eggs, this difference is significant.

What to Ask Any Egg Bank

Not all egg banks publish their survival rates. When you speak with any egg bank, ask this specifically:

“What is your frozen egg survival rate per thaw?”

If they cannot give you a direct answer, that is itself information worth having. A bank that tracks this metric carefully will know the number. A bank that cannot produce it may not be measuring outcomes at the level of precision that donor egg IVF requires.
