Frozen embryo transfer (FET) is a technique typically employed during in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) routines. The procedure is designed to cryopreserve surplus embryos after transferring up to two embryos to the uterus in any given fertility cycle. Embryos can be frozen at any stage of development during the IVF process. However, studies have shown that freezing embryos on Day 5 has its advantages. Such embryos are known as blastocysts.
What Is Frozen Embryo Transfer (FET)?
Why Choose Frozen Embryo Transfer?
Cryopreserving embryos for the future presents several advantages, including greater savings, access and convenience.
Allowing embryos to grow up to 5 days means that only the healthiest embryos survive, displaying natural selection. 5-day old blastocysts are more likened to organically developed embryos of a natural fertility cycle. As a result, the likelihood of implantation and pregnancy increase.
Repository of Surplus Embryos
The freezing of surplus embryos offers you a backup bank in case your first embryo transfer routine does not result in pregnancy. Frozen embryo transfer (FET) also entails a much lower cost and timeframe than if you were to restart an in vitro fertilisation (IVF) procedure from the ovum retrieval stage.
You may be advised by your doctor to freeze all your embryos in a given IVF cycle, especially when your endometrium exhibits traits of suboptimality. An underprepared endometrium may stem from the presence of a polyp or excessive endometrial fluid. In either situation, a transferred embryo presents minimal chances of implantation, and you may be advised to freeze your embryos until your uterus is more receptive.
Women with polycystic ovaries are prone to ovarian hyperstimulation. If severely stimulated ovaries are noticed, your embryo transfer may be postponed to the next month, allowing your ovaries enough time to heal.
Abnormally elevated hormones in an IVF cycle can adversely affect the endometrium and reduce chances of implantation. In such a case, a FET the following month is a recommended option.
Genetic Testing of Embryos
Genetic testing of embryos via preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS) is a useful tool to filter out embryos that display an unfavourable genetic predisposition.
Is Frozen Embryo Transfer Right for Me?
As you embark on your in vitro fertilisation (IVF) journey, it’s as important to be patient as it is to be positive. One of the reasons that healthy embryos fail to implant is a mismatch between their stage of growth and that of the endometrium. This could be because of high hormone levels or an array of other factors. Freezing embryos and transferring them in a subsequent cycle into an appropriately prepared endometrium offers superior pregnancy rates. Alternatively, you may choose to freeze your embryos if you plan on expanding your family further a few years down the line. On Cloudnine, the success rate of frozen embryo transfer (FET) is 60%, as compared to 40%, of fresh embryo transfers.
What Are the Steps of Frozen Embryo Transfer?
What Are the Risks of Frozen Embryo Transfer?
Frozen embryo transfer (FET) may give rise to risks if not carried out properly. On Cloudnine, we invest long hours ensuring that your procedure is seamless and that your risks are minimised.
Embryos are volatile and susceptible to damage when they are thawing, and that’s where the risk lies. If embryos are not thawed correctly, they can be encumbered by ice shards, and be damaged as a result. On Cloudnine, our advanced technologies are tailored to thaw embryos perfectly, ensuring that their survival rates are optimised.
Death of Cells
An embryo is made up of tens of cells, and sometimes, the thawing process could destroy some of them. However, a 100-cell embryo can generally withstand such weathering, and still be strong enough to survive inside the uterine cavity.
They say, ‘Never lose Hope’
Dr. Manju Nair was my doctor here at Cloudnine. I have a 9-year-old daughter but could not conceive for the 2nd time. After coming to Cloudnine not only were my spirits uplifted but my hope of conceiving after these many years turned into reality 🙂
Positivity spread across to enlighten our hearts
It was a good experience at Cloudnine. Dr. Uma is one of the best doctors in the city. She was very understanding of our situation and gave us a consultation in a very calm manner with much clarity. The atmosphere in Cloudnine is very positive and welcoming.
The touch of genuine care
The doctor assigned to us showed genuine care towards us and provided the best opinion, Dr. Uma explained all the processes involved with complete compassion. The environment was very comfortable. We give credit to cloudnine for this impressive treatment.
A great experience in making
The staff was immensely supportive, right from the support-desk staff, the nurses, to the doctors. I was guided and helped wholeheartedly. The entire team equally contributed to this great experience. I thank you all for it.
Dr. Manju Nair Has a Divine Persona
I don’t have enough words to describe Dr. Manju Nair’s qualities adequately. She is simply the best. She is confident, caring, friendly, positive and has some kind of magic in her hands. Among all the fertility specialists we met, she shone through with her divine persona. Dr. Nair’s vibrant personality made us feel comfortable and I thank her and her team for the wonderful care they took at every step of our treatment. Hats off to them all!
Dr. Manju Nair Is the Friendliest Doctor We Have Ever Met
This past year has been a wonderful journey for us. Dr. Manju Nair has helped us navigate highs and lows, and is the most honest and friendly doctor we have ever met. ‘Thank you’ doesn’t quite encapsulate the gratitude we have for her, and we are indebted to her for all she has done for us.
Coming to Cloudnine Fertility, Old Airport Road Was the Best Decision of My Life
I think I made the best decision of my life by coming to Cloudnine Fertility, Old Airport Road and meeting Dr. Manju Nair. She listened to my concerns with immense patience and calmed my fears about the scans I would have to undergo on my way to conception. A big thanks to her for tolerating the fuss and frenzy I inevitably made during each scan. Dr. Nair proposed a wonderful fertility treatment, due to which, I have now conceived twins. My husband, my family and I are grateful to her, and I would recommend any couple struggling to conceive, to meet her. Also, a big thanks to the support staff for being so considerate and taking such good care of me!
