How to Calculate the Due Date of an IVF Cycle

In vitro fertilization (IVF) is the process by which an extracted egg and sperm are united in a laboratory setting and then inserted into a woman’s uterus through the cervix in the hopes that the fertilized egg will implant and pregnancy will occur. Sometimes more than one fertilized egg will be implanted into the uterus in the hopes of increasing the odds of success. IVF is a process typically undertaken by couples who face difficulties achieving pregnancy through intercourse for various reasons. Once pregnant after an IVF process, estimating a due date requires only a few calculations.

  Add 266 days (38 weeks) to the date of the IVF procedure (date of conception). This is the estimated due date of the pregnancy.

  Use online calculators as another way to determine a due date after IVF. Many online calculators allow you to enter the date of conception and automatically estimate a due date based on that data. Note that a few websites directed specifically at couples who have undergone infertility treatments will ask for the date of egg collection or insemination, which is the date of the IVF procedure. See Resources for examples of websites with due date calculators.
