Understanding Blastocyst helps you read clinic and registry data correctly and judge your real cost per baby — the figure that actually matters when comparing IVF across countries. Our cost-per-baby tool and country pages use these terms with real CDC, HFEA and ESHRE data.
We compare IVF success rates, prices and laws across 12 countries — using real CDC, HFEA and ESHRE data — to show your true cost per baby, not per cycle. Donor eggs, age 40+, single or same-sex: we show where it's affordable and legal for you.
