The Brigham Egg Freezing Calculator estimates the probability of achieving at least one, two, or three live births from frozen eggs. This tool is crucial for women considering egg freezing as it helps in making informed decisions about how many eggs to freeze based on their personal circumstances and family planning goals.
Formula of Brigham Egg Freezing Calculator
The formula used in the Brigham Egg Freezing Calculator is:
P(at least X live births) = 1 – (1 – P(live birth per egg)) ^ (Number of eggs x Survival rate)
Here, P(at least X live births) represents the probability of achieving at least X live births. The P(live birth per egg) is the probability of a single thawed egg resulting in a live birth, which varies by age and fertility factors. Number of eggs is how many mature eggs are frozen, and the Survival rate generally stands at 95% or 0.95.
Table of Typical Scenarios
The following table provides a quick reference for common scenarios using the calculator:
| Number of Eggs Frozen | Survival Rate | Probability of at least 1 Live Birth | Probability of at least 2 Live Births |
|---|---|---|---|
| 10 | 95% | 65% | 40% |
| 15 | 95% | 80% | 60% |
| 20 | 95% | 90% | 75% |
Example of Brigham Egg Freezing Calculator
For instance, if a woman freezes 15 eggs, and the survival rate of thawed eggs is 95%, using the calculator, she can expect about an 80% chance for at least one live birth and about a 60% chance for at least two live births.
Most Common FAQs
The best age is generally in the late 20s to early 30s, but consulting with a fertility expert is recommended for personalized advice.
The calculator provides estimates based on general statistical data and should be used as a guide rather than a guarantee.
Yes, the calculator can help estimate the outcomes for multiple pregnancies by adjusting the number of live births you aim for.
