IVF / PGT-A Outcome Estimator
Use this igenomix calculator to estimate how many embryos may reach biopsy and how many might be euploid (chromosomally normal) based on age and cycle assumptions.
What is an igenomix calculator?
An igenomix calculator is a planning tool used by IVF patients to estimate outcomes during an egg retrieval cycle, embryo development phase, and PGT-A testing stage. It is not a diagnostic test and it does not replace your fertility doctor. Instead, it helps you turn key assumptions into understandable numbers.
Most people ask practical questions like:
- How many embryos might make it to day 5/6 biopsy?
- How many of those embryos might be euploid?
- What is my approximate chance of getting at least one euploid embryo?
This page answers those questions with a simple, transparent model so you can have more informed conversations during cycle planning.
How this calculator estimates embryo outcomes
1) Eggs Retrieved → Mature Eggs
Not every retrieved egg is mature enough for fertilization. The maturity rate converts total retrieved eggs into expected mature eggs.
2) Mature Eggs → Fertilized Eggs
Fertilization rate depends on multiple factors, including sperm parameters and lab processes. This step estimates how many mature eggs become normally fertilized embryos.
3) Fertilized Eggs → Blastocysts
Only a subset of fertilized embryos will reach the blastocyst stage and be suitable for biopsy/freezing. This is often one of the largest drop-off points in IVF.
4) Blastocysts → Euploid Embryos
Euploid rate is strongly related to age, but cycle-specific variation is normal. You can either use the age-based estimate in this igenomix calculator or input your own clinic-provided expected rate.
Age-based euploid defaults used in this tool
When you leave the custom euploid field blank, the calculator applies a broad age-based estimate:
- Under 30: 65%
- 30–34: 55%
- 35–37: 45%
- 38–40: 30%
- 41–42: 18%
- 43–44: 10%
- 45+: 5%
These are general planning values, not guarantees. Real laboratory outcomes can differ cycle to cycle.
How to use your result
Set expectations, not promises
If your estimate is low, that does not mean success is impossible. If your estimate is high, that does not guarantee a live birth. IVF outcomes are probabilistic, and individual biology matters.
Discuss strategy with your care team
- Whether to do one retrieval or bank embryos across multiple cycles
- Whether to adjust stimulation protocol in future cycles
- How to interpret mosaic findings based on your clinic policy
- How many euploid embryos may be reasonable for your family-building goals
Important limitations of any online IVF calculator
Even a well-built igenomix calculator cannot account for all biological and lab variables. Ovarian reserve markers, stimulation response, sperm DNA quality, embryo grading details, and lab-specific performance all influence final results.
Use this tool as an educational framework. For treatment decisions, always rely on guidance from your reproductive endocrinologist and embryology lab reports.
Frequently asked questions
Is this an official Igenomix tool?
No. This is an independent educational calculator inspired by common IVF planning workflows.
Should I enter my own euploid rate?
If your clinic has provided a personalized expected euploid percentage, use that value. Otherwise, leave the field blank and the age-based estimate will be used.
Why does the calculator show decimal embryo counts?
Expected values are averages. In real life, embryo counts are whole numbers and outcomes may be above or below the estimate in any single cycle.
