Frozen embryo transfer procedure is more popularly known as FET is basically a type of in vitro fertilisation treatment in which a frozen embryo or a cryopreserved embryo which was created previously in a full in vitro fertilisation cycle is actually transferred and thawed to the uterus of the female. In this procedure, the frozen embryo may also be a donor embryo instead of the previous conventional in vitro fertilisation of the female. At this point of time, it is to be kept in mind that if a donor embryo is being used at the time of frozen embryo transfer process, then the embryo would certainly not be related genetically to the female or her partner.
In this procedure, the females need not undergo one more cycle of stimulation of hormone and collection of eggs. The frozen embryo cycles can be very easily and conveniently undertaken on the natural cycle of the females or by the use of preparation of hormone or simply ovulation induction. At KARE, we have some of the most experienced doctors who make sure that the overall process of frozen embryo transfer is carried out smoothly without any kinds of interruptions with the hope of getting the ultimate result is a positive one.
Frozen embryo transfer is a process which is opted for because it provides a number of solid benefits which cannot be overlooked at any cost. This procedure of embryo freezing allow more opportunities for pregnancy for each of the hormone cycle and collection of egg. If it happens that the female does not get pregnant from the first transfer of the cycle, the expert doctors at KARE transfer a frozen embryo at the time of a frozen embryo transfer cycle. This clearly indicates that the females need not have to go for another cycle of hormone stimulation and collection of egg which is highly beneficial.
The Process of Freezing Embryos
The embryos can be frozen from the second day or Day 2 which is referred to as the four stage cell till the fifth day or Day 5 which is the blastocyst stage. Labelling is done by the doctors at KARE with a unique identification number along with name and are placed in very thin straws made of plastic which are sealed at both the ends. Then these straws are transferred into a freezing machine where the temperature maintained is around -150 degree Celsius. This process is called vitrification. Later, the straws are placed in goblets and then transferred to tanks which is filled with liquid nitrogen where the temperature maintained is around -196 degree Celsius. Utmost care is taken by the experts at KARE so that the overall process goes on perfectly.
The Place of Storage
The embryos so frozen are stored in an IVF facility where they are actually stored frozen in cryostorage till the time of next use or donation or simply discarded. But immense care needs to taken at each and every step to conduct the process appropriately.
