Precision Due Date Calculations for IVF Pregnancies

For parents conceiving through In Vitro Fertilization (IVF), the traditional method of calculating a due date based on the last menstrual period (LMP) is replaced by calculations based on the embryo transfer date. This provides an extremely accurate timeline for monitoring fetal growth.

How IVF Due Date Calculation Works

Because the transfer date represents a specific embryonic development stage, we calculate the due date by subtracting the embryo's age from the standard 266-day post-fertilization timeline:

  • 3-Day Transfer: Adding 263 days to the transfer date.
  • 5-Day Transfer: Adding 261 days to the transfer date.
