Should We Transfer One Or Two Embryos?
Transferring more than one embryo will increase the likelihood that at least one embryo will implant
Whether created through intercourse, artificial insemination, or In Vitro Fertilization, the majority of human embryos do not have the potential to hatch out and implant successfully.
In the U.S., there are no laws limiting the number of embryos to be transferred. However, at Bay IVF, we adhere to the recommendation of the American Society for Reproductive Medicine, which suggests that most patients should consider transferring only one or two embryos.
There is no “crowding” effect inside the uterus. If you choose to transfer two embryos, the probability of achieving a live birth is higher compared to transferring just one embryo. However, it’s important to note that transferring two embryos increases the chances of a twin pregnancy.
It is well-known that a singleton pregnancy carries the lowest risk for both the mother and the newborn. Therefore, delivering a full-term, healthy singleton is considered the best outcome following assisted reproductive technology treatments such as IVF.
The decision on the number of embryos to be transferred is typically finalized during the embryo transfer visit at our clinic. At that time, we will have information about the number of embryos available for transfer and their quality assessment. This allows us to estimate the probability of a successful outcome with one or two embryos transferred. Additionally, we will provide information about the approximate risk of a twin pregnancy if you choose to transfer two embryos.
With the advancement of highly reliable embryo vitrification (cryopreservation), many patients now choose to transfer only one embryo at a time.
While we will provide guidance on how many embryos to transfer, the final decision will be yours, and you can choose to transfer either one or two embryos.
We look forward to meeting you at Bay IVF and, when your treatment is successful, celebrating your new pregnancy!
