Frozen Embryo Transfer,Assisted Reproductive Treatment

Frozen embryo transfer (FET) also known as Frozen Embryo Replacement (FER), consists of the thawing of embryos which were frozen during previous IVF or related treatment, and the replacing of them in the uterine cavity at the appropriate time of the menstrual cycle.
In simple, Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy.
It is common during IVF/ICSI embryo transfer treatment for more embryos to be produced than are required at the time. Good quality embryos remaining after the initial embryo transfer can be successfully frozen and stored at extremely low temperature,which ensures that they do not deteriorate over the number of years they are stored.
This stored embryos are then embryo replacement, which allows a couple to have up to three or four cycles from the same egg collection.

Like the other conventional treatments like IVF or ICSI, Frozen Embryo replacement cycle does not require the ovaries to be stimulated. Instead Oestrogen is administered, normally in tablet or patch form. This enables the uterine lining to develop for the embryo’s to be replaced.In a Frozen Embryo Transfer Cycle, the woman takes medications to prepare her womb to receive these embryos.
The advantage of frozen embryo implantation treatment is that there is no need to use hormone injections to stimulate the ovaries.
An ultrasound scan is performed to assess the lining of the uterus to determine whether it is ready to receive the embryo. Once the lining is ready, embryos are thawed and transferred.

Dr. Soumyaroop Dash of Srishti fertility center, Puducherry,India is a leading infertility specialist who helps the couples to have a child with frozen embryo transfer procedure.
