How do frozen embryo transfers work?

Biological clocks often don’t work in our favour. Many people simply aren’t ready to have children when their body is the most primed to support a healthy pregnancy.

Thankfully, advances in cryopreservation have changed fertility treatment options dramatically. The process itself is when organs, tissues, or cells are cooled before being stored at very low temperatures, which maintains their viability over an elongated period.

That means you can pause your fertility at its prime and choose to go through the process of having a child when you are ready to do so, many years down the line.

One option that has become possible as a direct result of cryopreservation techniques is frozen embryo transfer (FET). This is when you choose to use embryos that have been cryopreserved following an IVF/ICSI cycle. Once the embryos are thawed, they are checked to ensure that they are still alive and growing before they are made ready for transfer.

Many people choose to freeze their embryos for many years until they are ready to care for a child.

The FET process

The FET process

Frozen embryo transfers carry from a previous IVF cycle during which viable embryos were formed and cryopreserved.

The transfer of a frozen embryo doesn’t differ too much from an embryo transfer following a fresh cycle or a cycle that does not involve the cryopreservation step.

Step 01

Before the transfer can take place, the embryo placed in cryopreservation is thawed and prepared for the procedure.

Step 02

A catheter containing the embryo is then inserted into the uterine cavity through the cervical channel with the guidance of an ultrasound.

Step 04

A pregnancy test can be scheduled twelve to fourteen days after the embryo has been transferred to the uterus.

Step 03

The catheter is then removed and checked to ensure that the embryo has been placed safely.

Our fertility specialist will advise you on the best time for the transfer to take place. Depending on your circumstances, the embryo may be placed during a natural cycle without the assistance of medication or in a cycle that is optimised with hormone supplements.

Things to know

Here at itrust fertility, we understand the value of cryopreservation and the opportunities they present to make your fertility journey smoother and the least invasive it can be.


Studies have shown that the results of frozen embryo transfers are the same—if not better—when embryos are used in several treatment cycles (a full treatment cycle, i.e. all the monitoring, tests and procedures required in a full episode of treatment) as opposed to the embryos that are transferred directly after the egg collection process.

 
Our IVF programme is supported by our cryopreservation storage facilities and is an essential part of what we do here at itrust fertility.

Things to know

How long can embryos be stored before transfer?

The HFEA reports that embryos can be stored for up to ten years with no adverse effects or reduced viability. 


When embryos are cryopreserved, they are stored at a temperature of close to -200 Celcius to make sure they don’t deteriorate over time. The success of your embryo transfer is generally not affected by the length of time they are stored for. 


Your embryos will be ready when you are.

How many embryos are needed for frozen embryo transfers?

Generally, frozen embryo transfers involve the transfer of one or two embryos at a time. If you are over the age of 40 this number may be raised to three.


At I Trust Fertility, our best practice is to transfer one embryo at a time to avoid the possibility of twins being conceived. As always, this is entirely up to you, and our fertility specialists will do their best to provide you with the right solution to suit your requirements, age, embryo quality, and how many embryos survived being thawed.

How does the FET process compare to the IVF cycle?

In general, an FET is a much easier process than an IVF cycle. 


This is chiefly because you don’t need to go through the hormone self-injection process required to stimulate your follicles into producing more eggs. You also don’t need to go through the egg retrieval procedure. 


All that’s required for this process is a round of hormones needed to prepare your uterine lining to receive the embryos during the transfer process. Your fertility specialist will be keeping a watchful eye on your progress through regular ultrasound monitoring.
