A tool used to estimate the expected date of delivery following a successful in-vitro fertilization (IVF) cycle involving a blastocyst transfer. It uses the date of the embryo transfer and the age of the embryo at the time of transfer (typically five days) to calculate the estimated due date (EDD). This EDD is based on the standard gestational period. For example, if a five-day embryo transfer occurred on March 1st, the calculator would add approximately 261 days (37 weeks) to that date to determine the expected delivery date.
The determination of a due date after an IVF cycle is beneficial for several reasons. It provides expectant parents with a timeline for pregnancy milestones, facilitates appropriate prenatal care scheduling, and aids in the management of potential pregnancy complications. Historically, accurate dating of a pregnancy was challenging, particularly for individuals with irregular menstrual cycles. IVF provides a precise starting point for calculating gestational age, leading to more accurate due date predictions compared to relying solely on the last menstrual period.
