Frequently Asked Questions
How is an IVF due date calculated?
For a Day 5 (blastocyst) transfer, add 261 days to the transfer date. For a Day 3 transfer, add 263 days — both reflect 280 days from a theoretical last menstrual period.
Is an IVF due date more accurate than a natural pregnancy due date?
Yes — since the exact fertilization date is known in IVF, the due date estimate is generally more precise than Naegele's rule used for natural conception.
