Frozen Embryo Transfer (FET) Procedure
Services / Service Details
What is Frozen Embryo Transfer?
A type of IVF treatment, the process of Frozen Embryo Transfer requires a cryopreserved embryo created in a full IVF cycle to be defrosted and transferred to a uterus. Typically, FET or Frozen Embryo Transfer requires embryos frozen from a previous IVF cycle to be used in a new cycle. The procedure is carried out in an unstimulated cycle/natural stimulation and requires diligent preparation and monitoring of the endometrium (uterus lining), set for the transfer of frozen embryos. With FET, you don’t need to go through an entire IVF cycle with injectable(stimulation ) again as you already have embryos.
Freezing the Embryo: All you need to know
When did people first start freezing embryos?
Why choose Frozen Embryo Transfer?
They have extra embryos
An IVF can typically result in several embryos. However, it is considered safe to transfer only one or two at a time as transferring multiple embryos is known to increase the risk of multiple pregnancy. In order to minimise this risk, doctors usually advise an elective single embryo transfer, and the remaining embryos to be cryopreserved. And if the transferred embryo doesn’t result in a successful pregnancy, you would have the option of transferring one of your previously frozen embryos, or use it at a later time to create a sibling.
They’re at a high risk of developing OHSS
There are times when a woman having IVF treatment is advised to freeze all her embryos. Typically, doctors recommend not to transfer the embryos immediately when the lining of the uterus or endometrium has not developed suitably or the patient is at a high risk of developing Ovarian Hyper-Stimulation Syndrome or OHSS.
They have a better chance at pregnancy during a later cycle
It is also common for fertility specialists to recommend freezing the embryos due to a more natural environment in the uterus during a later cycle, increasing the chances of a successful pregnancy.
They want to postpone pregnancy for later in life
For women who wish to postpone pregnancy until their late 30s or early 40s, freezing the embryo serves as a perfect option, as they may not have suitable eggs of their own by then.

Does Freezing mean that embryo quality will go bad & result will be less?
What is difference between Freezing & Thawing?
Freezing means your embryos are mixed with special medium and rapidly frozen to glassy state which is known as vitrification. Once vitrified embryos are stored in special container which contain liquid nitrogen Embryos can left like this for years together whenever patient wishes to conceive ,the lining of her womb is prepared with special medication or may be sometimes is natural cycle and then embryos are transferred in the womb. Some progesterone support are given afterwards. This process of taking out embryo from liquid nitrogen adding some medium and resuming it to normal is known as Thawing.
A Peek Into Delayed Frozen Embryo Transfer
Also referred to as freeze all IVF cycle, Delayed Frozen Embryo Transfer usually involves freezing all embryos created in an IVF cycle for potential future use.
- Reducing the pregnancy risks of fresh embryo transfer cycles.
- Allowing the uterus environment to return to normal after the retrieval of eggs.
