Guidance for elective single-embryo transfer should be applied to frozen embryo transfer cycles

Frozen-thawed embryo transfer cycles

In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...

Elective single embryo transfer

The aim of the study was to evaluate if the elective single embryo transfer (eSET) strategy could maintain the delivery rates, with at least one live born child, and at the same time decrease the rate of multiple births. A costeffectiveness analysis was also performed between the elective single embryo transfer (SET) (1+1) and double embryo transfer (DET)(2+0) strategies. Another aim was to inv...

Elective single-embryo transfer

N umerous publications have investigated the practice of elective single-embryo transfer (eSET) (1–27). Single-embryo transfer after in vitro fertilization (IVF) has been advocated as the only effective means to avoid multiple pregnancy in IVF cycles (28). Elective SET is defined as the transfer of a single embryo at either the cleavage or blastocyst stage of embryo development that is selected...

Morphological embryo selection: an elective single embryo transfer proposal

OBJECTIVE To describe a patient selection method for elective single embryo transfer (eSET), emphasizing inclusion criteria and results. METHODS This retrospective study included all cases seen in a private clinic between June 2011 and December 2016, in La Paz, Bolivia (3600 meters above sea level). Elective single embryo transfer was the method of choice in 34 IVF/ICSI cycles, all in the bla...
