Frozen Embryo Transfer (FET)
FET stands for Frozen Embryo Transfer. FET is a cycle in which a frozen embryo from a previous fresh IVF cycle is thawed and transferred back to the woman’s uterus. This means that you don’t have to go through another cycle of hormonal stimulation and egg collection.
The frozen embryo cycle can be carried out either in the natural cycle or by using hormone preparation or ovulation induction.
Clinical Studies of FET
Some clinical studies have shown that hormonal interventions can be harmful to endometrial receptivity and pregnancy success. Thus, in the absence of hormonal intervention, the true effect size of the FET in the natural cycle may be Read More
What are the Benefits of FET?
Ten years ago, Min and his colleagues strongly advocated a new indicator, BESST (Birth Emphasis on Successful Single Person in office), to measure the best outcome of the IVF cycle. Read More
Success Rates with Elective FET?

A systematic review and meta-analysis of three randomized controlled trials, including 633 women, assessed clinical and ongoing CPRS and abortion rates after effect and fresh embryo transfer.

In most cases, cryopreservation is performed when an "extra" embryo after a regular IVF cycle. “Fresh" transfer is usually preferred. However, some doctors recommend selective frozen embryos. This transfer is also identified as an "all frozen" method. In this case, all embryos are cryopreserved and transferred in the FET cycle around the next month. Read More
