Embryo selection tool
Estimates clinical pregnancy rate from historical frozen embryo transfer (FET) cycles in the PGT cohort: filter by embryo age (or any embryo age; use donor age if donor oocytes), biopsy day, number of embryos transferred, and morphology.
Morphology: with buttons, pick grade, ICM, and/or TE in any order — PR updates as soon as you select at least one; empty segments are not filtered. Or use the cohort dropdown.
Biopsy day: use any biopsy day to include all days, or pick 5, 6, or 7.
Embryos for FET: choose any number of embryos for FET to include all counts, or 1 or 2 specifically.
Dataset: 7,113 FET records .

Updates automatically when you change any filter.
Compare two embryos
Save the current filters and PR to slot A or B, then change the form and save the second embryo. Both snapshots stay until you clear them.
Empty — adjust the form and press Save current.

Clinical PR by morphology
For embryo age any embryo age, biopsy day 5, and 1: the ten most frequent morphologies (by FET count). Bar length = clinical PR (IUP / FET × 100%).
Bar color: pink if clinical PR <40%, blue for 40–55%, green for ≥56%.
Clinical PR by embryo age
For morphology 5AA, biopsy day 5, and 1: each bar is an embryo age group (same buckets as the age dropdown) with at least one FET. The Embryo age control above filters the main result only — this chart shows all age groups for comparison. Bar length = clinical PR (IUP / FET × 100%).
Bar color: pink if clinical PR <40%, blue for 40–55%, green for ≥56%.
Embryo morphology in IVF cycles — exploratory analysis
Full-cohort charts: morphology and age frequencies, morphology × age and morphology × biopsy day heatmaps, biopsy day vs clinical PR, quality vs clinical PR, expansion grade, morphology vs PR, and age vs PR—all unfiltered by the calculator above.
