How do I Calculate a Gestational Carrier's Due Date?

The heart-wrenching challenge of couples experiencing infertility often leads to creative solutions. One way to solve fertility problems is to use a gestational carrier. A gestational carrier provides a host uterus that will carry a fetus created by in vitro fertilization of the egg and sperm of the intended parents. A surrogate carrier differs from a gestational carrier as the surrogate contributes her own egg fertilized by the intended father's or a donor's sperm. Calculate a gestational carrier's due date with a simple equation.

• 1

  Note the egg retrieval date on a calendar. This is fertilization day (similar to ovulation day for a typical cycle).

• 2

  Count forward on the calendar 38 weeks or 266 days from the egg retrieval date. For example, if the eggs were retrieved on January 7, count forward 38 weeks or 266 days.

• 3

  Note the date on the calendar. This is the estimated date of confinement. Using the same example, the EDC is September 30.
