A companion to "Pregnant at 50: Miracle, Medicine, or Missing Information?" Headlines report one age. Real biology tracks four clocks — egg, uterus, sperm, and parenting. This tool shows the egg-age numbers behind the headlines.

Illustrative figures based on published IVF age-outcome ranges, rounded for clarity — every clinic and case is different. Cumulative math assumes independent cycles, which real life rarely is.
Not a prediction for you specifically. As Dr. Amols says: euploid (genetically normal) embryos change the odds but don't erase age completely, and donor eggs reset the egg clock — not the pregnancy or parenting clock. Ask your own doctor about your own numbers.
