Egg Freezing Calculator
Estimate how many eggs you might need to freeze for a reasonable chance of future pregnancy. This calculator helps you understand the numbers behind egg freezing and set realistic expectations.
Your Situation
Egg Freezing by Age
| Age | Eggs Needed | Typical Cycles | Success Rate* | Egg Quality |
|---|---|---|---|---|
| Under 35 | 10-15 | 1 | 70-80% | Excellent |
| 35-37 | 15-20 | 1-2 | 60-70% | Very Good |
| 38-40 | 20-25 | 2-3 | 40-50% | Good |
| 40-42 | 25-30+ | 3-4 | 25-35% | Fair |
| 43+ | 30+ | 4+ | 10-20% | Lower |
*Estimated chance of at least one live birth when using all frozen eggs
Factors That Affect Success
Age at Freezing
The most important factor. Younger eggs have higher quality and better freeze/thaw survival rates.
Number of Eggs
More eggs = better odds. Not all eggs survive thawing, fertilise, or become viable embryos.
Lab & Freezing Method
Vitrification (flash-freezing) has higher survival rates than slow freezing. Lab expertise matters.
Ovarian Reserve
AMH levels and antral follicle count predict how many eggs you'll get per cycle.
