This tool estimates the expected date of delivery following a successful assisted reproductive technology procedure utilizing cryopreserved embryos. Unlike natural conception or fresh embryo transfers, the timing of implantation is precisely controlled during a frozen cycle, allowing for a more accurate prediction of the gestational timeline based on the age of the embryo at the time of freezing and the date of uterine transfer. For instance, a five-day blastocyst transferred on a specific day will have a predetermined developmental age, and the delivery date is calculated accordingly.
Accurately forecasting the delivery date provides several key advantages. Obstetricians can precisely schedule prenatal care appointments and anticipate key developmental milestones. Patients benefit from a reduced uncertainty regarding their pregnancy’s progression. Historically, estimating delivery dates relied on the last menstrual period, which is not applicable in frozen embryo transfer cycles. The ability to pinpoint the gestational age with greater precision has improved the management of high-risk pregnancies and allows for the informed planning of labor and delivery.
