Egg Freezing Success Rate Calculator

Your details

Your age when the eggs are retrieved and frozen. Age is the single biggest driver of success rates.
years
Only mature (MII) eggs are viable. Immature eggs retrieved in the same cycle are not counted.

With 12 frozen eggs at age 32, your estimated chance of at least 1 live birth is 84.7%.

  • At age 32 (30-34), each frozen mature egg has about a 14.5% chance of resulting in a live birth.
  • From 12 eggs, roughly 11.0 are expected to survive the warming process, 3.6 to reach the blastocyst stage, and 2.2 to be chromosomally normal and available for transfer.
  • You have already reached the threshold (around 11 eggs) associated with an 80% chance of at least one live birth for your age group.
  • Your estimated probability of achieving your goal of 1 child is 84.7%.

Next stepThese estimates are based on population averages. Your personal AMH level, antral follicle count, and clinic-specific outcomes can all shift the probabilities. Ask your clinic for their own age-stratified live-birth-per-egg data.
