What is Frozen Embryo Transfer (FET)?
Frozen Embryo Transfers (FETs) are when you use embryos that have been cryopreserved, from a previous IVF/ICSI cycle. They are thawed, checked to ensure that they have survived and are growing, and transferred into your uterus.
The whole process is a lot simpler than an IVF cycle as you do not need to take the follicular stimulating hormones that you previously self-injected to produce the eggs, and you do not need to have the procedure to retrieve the eggs from your ovaries. Instead, you will take hormones to build your uterine lining in preparation for receiving the embryos. You will still need to be monitored by ultrasound to check progress.
Freezing is now an essential part of every clinic’s IVF programme. Studies have proven that results are the same if not better when embryos are transferred in cycles rather than directly following egg collection. Thanks to improved freezing techniques.
* Cryopreservation: The process of cooling and storing cells, tissues, or organs at very low temperatures to maintain their viability.
