Yes, Elective Single-Embryo Transfer Should Be the Standard of Care

  • Chapter
Book cover Biennial Review of Infertility

Abstract

Despite early warnings of assisted reproductive technology (ART) pioneers about the risks of multiple births, the desire to improve effectiveness of ART procedures led to the widespread practice of multiple-embryo transfer. Adverse consequences for both the pregnant mothers and their children followed suit. Recognizing the risk of multiple births, the field is gradually moving toward elective single-embryo transfer (eSET) as the standard of care in good-prognosis patients. Overwhelming evidence from observational studies and randomized control trials supports the view that reliance on eSET versus on double-embryo transfer in appropriate groups of patients reduces perinatal morbidity and mortality, improves the likelihood of a healthy singleton infant, and reduces healthcare costs. Effective strategies for overcoming the barriers toward widespread implementation of eSET include the provision of expanded insurance coverage for infertility therapy coupled with limits on the number of embryos to transfer, as well as ongoing patient education on the benefits of eSET and risks associated with multiple births. From clinical, economical, and public health perspectives, transferring one embryo at a time in the context of good-prognosis infertility patients will lead to the most desirable outcome of ART – a healthy singleton infant.
