A frozen embryo transfer (FET) is a cycle where a frozen embryo from a previous fresh IVF cycle is thawed and transferred back into a woman’s uterus. This means you won’t have to undergo another cycle of hormone stimulation and an egg collection. Frozen embryo cycles can be undertaken on your natural cycle or using hormone preparation, or ovulation induction. In a conventional IVF treatment cycle, multiple egg follicles (10 to 15) are typically produced through hyperstimulation of a woman’s ovaries resulting in the development of several high-quality embryos in vitro. Today’s standard practice of care is for only one or two fresh quality embryos to be transferred directly to the woman’s uterus for hopeful implantation into her uterine lining. This practice reduces the chances of multiple pregnancies. To increase their chances of future pregnancies, many couples are preserving their embryos through embryo cryopreservation rather than undergoing multiple fresh IVF cycles. After a fresh IVF cycle, excess quality embryos are cryopreserved for future Frozen Embryo Transfer (FET) procedures.
