Frequently Asked Questions
How is IVF due date calculated?
For a 5-day blastocyst transfer: add 261 days to transfer date. For a 3-day embryo transfer: add 263 days. These account for embryo age at transfer.
Why is IVF due date different?
In IVF, the embryo's age is known precisely. A 5-day embryo is already 5 days old, so fewer days are added compared to natural conception dating.
What is the difference between 3-day and 5-day transfer?
A 3-day transfer uses a cleavage-stage embryo. A 5-day transfer uses a blastocyst. Blastocyst transfers generally have higher success rates.
