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
Sometimes during an IVF cycle, we’ll be able to create more than one embryo. We’ll usually recommend transferring one, and freezing the others. This is due to the serious risks associated with multiple pregnancies if you transfer more than one embryo at a time.
Embryo freezing gives you more opportunities for a pregnancy for each hormone stimulation cycle and egg collection. If you do not become pregnant from the first transfer from that cycle, we can transfer a frozen embryo during a frozen embryo transfer cycle.
