What is a Frozen Embryo Transfer?
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.
How does it work?
01
Embryo Freezing
Embryos are frozen at Adora Fertility on days five and six after the egg collection. Not all embryos will be suitable for freezing and some couples may not have any embryos suitable for this procedure.
Embryos will only be frozen if they have grown to the right stage, they are of sufficient quality to survive the freezing and thawing process and if they have potential to form a pregnancy. These embryos can stay in storage for five years.
02
Monitoring Your Cycle
Your cycle is monitored with or without medication. Our aim is to transfer the embryo into your uterus at the correct time in relation to your ovulation and the thickness of your uterus lining (endometrium).
Your cycle will be tracked with blood tests and ultrasounds as advised by your Adora fertility specialist and nursing team.
03
Embryo Transfer
On the day of transfer, your embryo will be thawed. Not all embryos survive the freezing and thawing process, in fact, approximately 5% do not survive. In these circumstances you will be contacted by the embryologist if there is a problem.
04
Follow Up
Once your transfer has occurred you will continue any medication you have been asked to take. You’ll also be advised when your pregnancy blood test is due.
