Understand · educational ranges
Family goal simulator.
Three pathways with uncertainty at every step — not a single false personal percentage. Clinic counseling still owns the plan.
Educational ranges · not a fertility score
family-goal-sim-v0-tables
Transparent attrition ranges for education — not a personalized clinical probability model. No AUC claim. Not calibrated to Patriot or any single clinic.
Stage ranges
Mature eggs (this plan)5 – 9 – 13
Illustrative age/AMH band — not a prediction
Blastocysts (approx.)1.8 – 4.5 – 8.5
Assumes ~35–65% of mature eggs reach blastocyst — lab-dependent
Euploid embryos (approx.)0.7 – 2 – 3.9
From age-banded rates × mature eggs
Potential live births (very rough)0.3 – 1.1 – 2.5
Per-euploid live-birth rates vary widely by clinic and uterine factor
Three pathways
Conservative path
At the low end of each step: ~0.7 euploid and ~0.3 potential live births from this plan.
Median path
Mid bands: ~2 euploid and ~1.1 potential live births — still a wide real-world spread.
Optimistic path
High bands: ~3.9 euploid and ~2.5 potential live births. Do not treat as a promise.
Limitations
- Does not predict live birth for you
- Does not replace REI counseling
- Lab, protocol, PGT platform, and uterine factors dominate outcomes
- AMH (if entered) only shifts egg-count narrative bands
- Donor-egg mode uses younger-donor illustrative rates
Questions for your REI
- Given my age and prior cycles, how many mature eggs or euploid embryos do you recommend banking for my family size?
- How do your lab’s blastocyst and euploid rates compare to these educational bands?
- Should we plan one retrieval or sequential banking before a surrogate transfer?
- How does PGT-A counseling change the number of embryos we discuss transferring or storing?
