An IVF procedure known as a frozen embryo transfer (FET) involves freezing and implanting an embryo that has been cryopreserved from an earlier egg retrieval cycle. The gestational parent’s frozen embryos from an earlier conventional IVF round are frequently used in frozen embryo transfer procedure.
Your doctor might advise FET to assist you get conceived if you have particular health issues, relevant circumstances, or other factors.
Process of FET
If the initial IVF cycle is unsuccessful, the second IVF cycle can choose from the frozen embryos. The frozen embryo transfer treatment cycle is the name given to this cycle.
FET eliminates the requirement for a fresh IVF cycle because frozen embryos from an earlier IVF treatment are already present. You can use FET to transfer a frozen uterus if IVF was unsuccessful because the embryo failed to attach into the uterus, rather than initiating a new IVF round.
When frozen embryos are transferred, they are first kept in liquid nitrogen at a temperature under minus 196 degrees Celsius after being frozen. These froze embryos will be defrosted and put into the woman’s womb. You cannot use the fertility medication during this entire cycle, nor can you collect eggs and sperm for lab fertilization. In the frozen embryo transfer, the age of the women is also quite important.
What Situations Demand for the Use of Frozen Embryo Transfer?
The transfer of frozen embryos is sometimes advised by doctors, even though FET is often recommended in association with IVF to boost the likelihood of implantation.
- Frozen embryo transfer is advised if the woman has a greater risk of OHSS. The embryo must be frozen in order to minimize OHSS.
- It is perfect for females who have uterine malformations or inconducive uteri. The likelihood of implantations with an inconducive uterus is extremely low. Therefore, experts advise using frozen embryo transfer procedure to improve the likelihood of implantation.
- Best IVF team advises frozen embryo transfer if the first IVF round was unsuccessful in order to raise the likelihood of pregnancy.
- For blastocyst development, frozen embryo transfer treatment cycle is also advised. Frozen embryo transfer is necessary whenever blastocyst culture is used in IVF in order to choose the healthiest embryo.
- With the aid of FET, it is the ideal option to reduce the price and duration of IVF therapy. If you were to try IVF once again, you would have to start at the egg retrieval stage, which is more expensive than FET.
- FET works best in women with unusually increased hormone levels. The endometrium may be negatively impacted by the aberrant hormones, which could lower the likelihood of implantations.
- When embryos must be genetically tested. PGD, or pre-implantation genetic diagnosis, can only be performed after the embryos have been frozen.
Procedure for Frozen Embryo Transfer Using PGD/PGS
Preimplantation genetic diagnosis and preimplantation genetic screening may be used in conjunction with the frozen embryo transfer treatment cycle. To choose the best embryo, clinicians employ pre-implantation genetic diagnosis. When compared to traditional IVF cycles, the miscarriage chances are significantly lower with PGD treatment. With their initial IVF, FET, and PGS attempts, more over half of couples with women below the age of forty will give birth to a living child.
With the use of his extremely scientific methodology, experts are able to accurately inform expecting couples about how to have a safe pregnancy and baby.
Egg, Sperm, and embryo freezing has gained enormous popularity during the past few years. For fertility therapy, frozen embryo transfer procedure is employed. In a process similar to cryopreservation, embryos are also frozen before being transferred to the uterus to enhance the likelihood of implantation.
