The reason behind this phenomenon is that not all the embryos are capable of reaching day 5 and becoming a blastocyst - which in some occasions could lead to transfer cancellation. Generally speaking, there is a higher likelihood to have an actual transfer if the choice is to transfer on day 2 or 3. It is essential to understand what difference this makes to the rate of success. There are important differences to highlight between transferring an embryo at the cleavage stage (day 2 to 3) or when they become blastocysts at day 5 and day 6.

For example, fresh embryo transfers for women undergoing pre-implantation genetic testing for aneuploidies, or for single gene disorders, may be performed on day 6 - but some units now freeze all the embryos and replace in future cycles. Usually, the procedure is performed on day 2, day 3 or day 5 of the embryo development but occasionally, due to certain cycle requirements, it might be performed on day 4 or day 6. Together you will discuss your wishes and decide the best day to transfer the embryos back into the uterus. They will evaluate the quality of your embryos, the number available and your background (including maternal age, previous treatments, medical history, etc.) among other relevant information. The day of the embryo transfer is typically decided by the embryology team. At your planning session, this will most certainly be discussed but the final decision may not actually be made until the potential day of your transfer.

One of the most important influences to consider is the day embryo transfer should take place. More reliably, your case specialist or nurse should also be able to help you nail down a specific date and gestational age.Ĭlick here to contact Growing Generations for more information.We are focused on maximising your chances of pregnancy. There are a great number of online calculators to help you get an accurate age and due date. These pregnancies are often delivered before 40 weeks gestation.Ĭalculating gestational age in IVF can be confusing. Multiple pregnancies are more common in IVF. An exact gestational age and estimated due date will be determined at the first ultrasound based on the size of the gestational sac and the fetus inside. A 5-day embryo is equivalent to a gestational age of 2 weeks and 5 days.Īt the close of the two-week wait between transfer and beta pregnancy test, you could be up to 5 weeks pregnant, depending on the age of your embryo at transfer. In general, transferring a 3-day embryo will leave you 2 weeks and 2 days pregnant as you leave the office. This adds up to a clearer picture of gestational age. In these instances, the exact date of ovulation, fertilization, and conception are known. The nature of IVF allows for more specific date stamping. Therefore gestational age in IVF, and by virtue in surrogacy, begins accumulating well before transfer. By the time conception occurs, the gestational age is already somewhere around two weeks. In a traditional pregnancy, gestational age begins accumulating on the last day of your menstrual period.

In this way, you are transferring an embryo into your uterus that already has an age assigned to it. Gestation is determined by the age of the egg as opposed to the time spent carrying it. Many people don’t realize that when using IVF, you don’t begin counting those 40 weeks on the day you transfer the embryo into your uterus.

Human pregnancies are counted in weeks, with 40 weeks being considered a full term.
