At Brown Fertility, our goal is not only to conceive miracles, but also to do our best to ensure a healthy pregnancy. Single Embryo Transfer (SET), a procedure in which one embryo, selected from the couple’s total number of embryo’s retrieved, is placed in the uterus. Embryos selected for SET may come from the couple’s current fresh IVF cycle or from a previous batch of cryopreserved embryos. Couples often want to increase their chances of a successful pregnancy by transferring multiple embryos at a time. However, today’s newer methods allow our team to identify the strongest embryos for transfer resulting in success rates that are comparable to and safer than a multiple embryo transfer as performed by most fertility centers.

What are the risks associated with multiple births?

Multiple births increase the risk of pre-term delivery, which can lead to low birth weight, developmental disabilities and delays. For the mother, multiples often require delivery by caesarean section (C-section). This can be accompanied by other health complications and is a longer and harder recovery for a mother now responsible for the care of multiple infants. At times, not all multiples can be sustained in the uterus until birth, which could lead to a medical necessity for fetal reduction. This process can be physically and emotionally taxing on the mother. Candidates for SET will benefit by avoiding these risks.

Who is a Candidate for SET?

You might be a good candidate for SET if you are younger than 38 and produce good quality eggs and embryos. The American Society of Reproductive Medicine (ASRM) established guidelines suggesting a maximum of 1 to 2 embryos transferred for a female under the age of 35. This maximum is reduced to a single embryo transfer for that age group if the transfer is done on a day 5 blastocyst. At Brown Fertility, 95% of our embryos are transferred as a day 5 blastocyst. Thus, a majority of our fresh transfers are done using SET. These guidelines are for patients with a “favorable prognosis” and take into consideration not only the age of the female but other pertinent health factors.

What are the success rates for SET?

At Brown Fertility, we uphold the ASRM guidelines, placing one embryo in patients 35 or younger during a fresh cycle and one to two embryos during a frozen one. Our success rates for this age group are consistently higher than the National average at an average of 80%. Some months our fresh IVF cycles see rates of 100%!

While we are very proud of these numbers and feel great joy in helping couples achieve their dreams of starting a family, our team will never prioritize success rates over the safety of our patients. Single Embryo Transfer is one of the many ways we are able to control the health and wellness of our couples and their future miracles.
