Frozen Embryo Transfer (FET)
Frozen Embryo Transfer at
Birla Fertility & IVF
FET or Frozen Embryo Transfer is the process of thawing embryos and transferring them into the uterus. Studies indicate that transfers performed in later unstimulated cycles have better results as compared to transfers right after egg collection. Advances in freezing technology have enabled an improvement in the survival rate for frozen embryos after vitrification and thawing.
At Birla Fertility & IVF, we offer FET as an additional procedure in your IVF cycle as well as a separate treatment if you wish to use frozen embryos from previous cycles.
Why Frozen Embryo Transfer?
If you have menstrual irregularities or ovulation disorders
If the transfer needs to be cancelled after egg collection due to the hormone therapy
If you are using genetic screening
If you wish to use frozen embryos from previous IVF treatments
The Frozen Embryo Transfer Process
Frozen embryos can be thawed and transferred into the uterus in a natural (unstimulated) cycle or in a cycle primed with fertility medications depending on your medical history and age. In a stimulated Frozen Embryo Transfer cycle, you will be given fertility medication to increase the thickness of the endometrial lining (lining of the uterus). During your hormone therapy, routine ultrasound scans are used to monitor the development of the endometrial lining. The transfer process is done once it has achieved the desired thickness, indicating the best uterine environment for implantation of the embryo.
The embryos are thawed on the morning of the procedure and transferred carefully into the uterus using a thin catheter under ultrasound guidance.
You will be asked to take a pregnancy test 12-14 days after the transferring procedure. Based on the results, our team will help you plan the next steps in your fertility journey.
Frequently Asked Questions
What is the full form of FET?
FET is the acronym of Frozen Embryo Transfer. It is the process of thawing embryos and transferring them into the uterus.
What are the risks associated with Frozen Embryo Transfer?
Not all embryos survive the freezing and thawing process. The risk of damage of destruction of embryos during the treatment depends on the quality of the embryo prior to being frozen.
What are the success rates for Frozen Embryo Transfer?
Success rates of Frozen Embryo Transfer cycles have increased due to advancement in freezing techniques and equal those of fresh embryo transfers. The treatment outcome also largely depends on factors such as maternal age and cause of infertility.
When are embryos frozen?
Embryos are frozen on day 2 (cleavage state) or day 5 (blastocyst stage) of their culture.
Does the duration of embryo storage impact success rate?
Successful transfers do not depend on the duration for which the embryos were stored. Frozen embryos are stored at -200°C in suspended animation and will not deteriorate with time if the temperature is maintained.
I had a good experience with my IVF treatment in Birla Fertility & IVF. The whole team was very supportive, motivated and well managed throughout the IVF treatment. The doctors’ team recommended a frozen embryo transfer, and everything went well. I would highly recommend Birla Fertility to all couples suffering from infertility. Thanks to the whole team.
