Frozen Embryo Transfer

FET

In many cases, a frozen embryo transfer is the final step in an IVF or ICSI journey. If embryos have already been created and frozen, FET allows for one of these embryos to be thawed and transferred at a later date when the body is prepared and the timing is appropriate.

This stage can feel like a hopeful next step after a previous cycle. It is also usually easier than going through a complete IVF or ICSI cycle again. Our doctors and nurses will guide you through the process with clear information, personalised planning, and supportive care. This way, you will know what to expect before, during, and after treatment.

Understanding more about a Frozen Embryo Transfer

with Senior Fertility Midwife Emma

What is a Frozen Embryo Transfer and how does it work?

There are two kinds of embryo transfer: fresh and frozen. A frozen embryo transfer, also known as FET, occurs when an embryo created in an earlier IVF or ICSI cycle is thawed and transferred into the uterus.

If you have been wondering what a frozen embryo transfer is, it is simply the transfer of a previously frozen embryo at a later date, rather than in the same cycle as egg collection. Embryos are often frozen to provide a more optimal opportunity to prepare the body for transfer.

Frozen transfers can be just as effective as fresh transfers. In many cases, they may provide better conditions for implantation. This is because it can be easier to prepare the uterine lining and hormone levels in a different cycle. If our doctors think a fresh transfer may not be the best option, they might suggest a freeze-all approach and plan for a frozen transfer instead.

The Frozen Embryo Transfer process

  • 01

    Uterine preparation

    The first stage of FET is preparing the body to receive the embryo. This usually involves frozen embryo transfer medication, such as oral or injectable hormones, to help build and support the uterine lining.

    Throughout this stage, you will attend monitoring appointments so our team can check how the lining is developing. Once the lining reaches the desired thickness, the timing of the transfer is carefully planned. Progesterone is then used to help prepare the uterus for the embryo.

  • 02

    Monitoring and coordination

    Careful timing is one of the most important parts of a frozen embryo transfer procedure. Monitoring appointments help your doctor decide when conditions are most suitable for transfer, based on your uterine lining and hormone response.

    If you are wondering which day of the cycle is best for frozen embryo transfer, the answer depends on your medication plan and how your body is responding in that cycle.

  • 03

    Embryo thaw and transfer

    On the day of embryo transfer, the embryo is thawed and prepared in the laboratory. The embryo is then placed into the uterus using a fine catheter in a simple procedure that does not require anaesthesia.

    The transfer itself is usually quick. Positioning is confirmed using abdominal ultrasound, so you will usually need a full bladder for the procedure. After transfer, our team will explain what happens next, including medication, blood test timing and what to expect in the days that follow. You will attend the clinic about 10 days later for a blood test to check if you are pregnant.

Who is a Frozen Embryo Transfer suitable for?

Frozen embryos can be stored for future use, and there is no fixed limit on how long an embryo can remain frozen. If you have embryos in storage and are thinking about next steps, our team can talk you through timing, medication and what may be realistic for your individual circumstances.

  • You have frozen embryos from a previous treatment cycle
  • A fresh transfer was not recommended in your original cycle
  • A freeze-all cycle was planned
  • You are returning to use embryos for another pregnancy attempt
  • You would like a treatment pathway that is more straightforward than repeating a full IVF or ICSI cycle

A frozen embryo transfer may be suitable for anyone who has embryos already frozen from a previous IVF or ICSI cycle and wishes to use them to try to become pregnant.

How do I know if I need a Frozen Embryo Transfer?

You may need a frozen embryo transfer if you already have embryos in storage from a previous IVF or ICSI cycle and want to use them to try to become pregnant. It may also be recommended if your earlier cycle was planned as a freeze-all cycle, or if a fresh transfer was not considered the best option at the time.

The best way to know whether FET is the right next step is through a consultation. Our doctors will review your treatment history, embryo storage details, cycle timing and any medication needed to help you move forward with clarity.
