Single Embryo Transfer

Single Embryo Transfer (SET)

Would you judge a book by its cover?

In the not so distant past, that’s exactly what doctors did when they chose which embryo to implant during IVF. Looking under a microscope, doctors would first choose the embryo with the most number of cells. But since they didn’t know how it would perform in the uterus, they chose another embryo that looked good, and sometimes, a third, too. Those would all be transferred back, hoping one would stick.

Often, two stuck, and sometimes more, leading women down a road of high-risk pregnancy.

With advances that were pioneered by our network, single embryo transfer – where only one embryo is transferred – is fast becoming the standard of care across the industry.

Single embryo transfer is possible thanks to breakthroughs that allow doctors to know much more about embryos than the number of cells they have. Thanks to NexCCS, Reproductive Medicine Associates of Northern California doctors can now look at the chromosomal makeup of embryos to decide which one has the best chances of leading to a pregnancy and live birth.

Because we are committed to healthy mother and child.

More about Single Embryo Transfers

More than 40 years after the first successful in vitro fertilization (IVF) procedure, the American Society for Reproductive Medicine stated an opinion that “The goal of infertility treatment is for each patient to have one healthy child at a time.” Nevertheless, twin birth rates in the United States continue to rise.

Although the majority of twin births in the U.S. occur through natural conception, the incidence of twins resulting from stimulated ovulation and assisted reproductive technologies (ART) rates higher than 20 times greater than that of naturally conceived twins.

IVF touches many stakeholders – patients, offspring, healthcare providers, insurance companies, and employers of patients undergoing the time-consuming and invasive treatments. Each of these groups may primarily focus only on its own immediate concerns and needs, not incorporating how each step and choice along the path are intricately tied to one another.


In addition to working to avoid health risks associated with carrying multiples such as an increased chance of Caesarean section and longer recovery periods following birth, Reproductive Medicine Associates of Northern California can also prevent the numerous medical complications that affect twins, triplets, or higher multiples during pregnancy, premature birth, low birth rate, and respiratory issues.
