Understanding Egg Freezing Success Rates
Success Rate Formula
The calculator uses validated research from Goldman et al. to estimate success probabilities based on your age and number of frozen eggs.
P≥1 = 1 - (1 - 0.6 × PE × PB)^n
- P≥1: Probability of at least one live birth
- PE: Probability of euploid blastocyst
- PB: Probability of blastocyst formation
- n: Number of frozen mature eggs
- 0.6: Live birth rate per euploid blastocyst
Age-Related Decline
Egg quality and quantity decline with age due to chromosomal abnormalities and reduced ovarian reserve.
Important Considerations
Before Freezing
- • Complete fertility assessment
- • Consider family planning timeline
- • Evaluate financial costs
- • Research clinic success rates
- • Consider emotional aspects
Limitations
- • No guarantee of pregnancy
- • Not insurance against infertility
- • Requires future IVF process
- • Storage costs and time limits
- • Multiple cycles may be needed
