FET does help in the IVF process and although there is a cost involved, patients find this procedure very useful. The success rate of FET is high and has proved to be a method that is viable and effective.
What is FET (Frozen Embryo Transfer)?
FET means frozen embryo transfer. In Vitro Fertilization (IVF) treatment, patients who have undergone IVF resulting in healthy embryos that had been frozen can also opt to make use of those frozen embryos instead of fresh ones. Best IVF Hospital in Hyderabad, IVF treatment in Hyderabad is no doubt excellent.
The cost factor of FET
FET does reduce costs significantly, and in some cases also increases the chances of success. The reason is that frozen embryos are indeed very viable and fertilization has already occurred.
When patients make use of frozen embryos, they can rather skip the egg retrieval and fertilization process, saving thousands of dollars in medication and treatment costs.
FET Procedure :
In IVF making use of fresh embryos, the cycle consists of the following common steps:
- Cycle suppression
- Ovarian stimulation
- Egg and sperm retrieval
- Fertilization
- Transfer
But as far as FET cycles are concerned, none of the steps prior to transfer other than cycle suppression are required. Fertility specialists will indeed administer suppression of medication and may also administer some medications to thicken as well as improve the uterine lining, but other than that, the majority of IVF procedures are eliminated.
General Trends with FET Success Rate :
FET does increase the chances of success in multiple rounds of IVF.
Some clinics quote the chances of success per FET as high as 60% in women aged 35 or even younger. Best IVF Hospital in Hyderabad, IVF treatment in Hyderabad has shown positive FET results.
The age of the mother at the time the eggs were retrieved and fertilized before freezing needs to be considered. This is a primary variable in the success rate. Despite the time factor of how has passed, the mother’s age at egg retrieval does impact the success rate.
By focusing upon the egg quality and quantity both decrease with age, some patients do opt to freeze extra embryos in the first few rounds of IVF. This does increase the chances of success later, in case IVF fails in the initial rounds.
Factors that Impact FET Success Rate Quantity
The number of healthy embryos that happen to be successfully frozen as well as thawed does impact the FET success rate. Typically, people tend to forget that embryos need not survive the freezing process, but they need to survive the thawing process and then also survive the transfer.
Viability
Patients can go in for testing and evaluation of the quality of embryos. Some can also choose to test them prior to freezing, while other patients will wait until another round of IVF is required. Cost, of course, does impact, as testing does lead to additional costs. Ivf best hospital in Hyderabad, IVF treatment in Hyderabad does provide facilities. Best IVF Hospital in Hyderabad, IVF treatment in Hyderabad does cater to the needs of FET patients.
If thawed embryos are tested and determined to be unfit for transfer, the chances of success do sharply decline. On account of this, several patients prefer to have the embryos tested prior to the freezing of the embryo. The only major issue with testing prior to freezing is that some embryos do tend to get damaged in the process of testing.
Maternal Age
The mother’s age at the time of egg retrieval does impact the success rate of frozen or fresh IVF rounds. This is happening to be the primary contributing factor, as age does impact both quantity and viability of the embryos.
Age of Embryo (Day 3 vs Day 5)
The older embryos (Day 5 embryos called Blastocysts) do have a greater chance of success than zygotes (Day 3 embryos). Blastocysts have survived longer and are also exposed to further development.
Freezing Method and Clinical Procedures
Embryos are rather fragile and do not live outside of one’s uterus. In IVF, the manner clinics freeze and thaw embryos do have a major impact on IVF success in the present as well as the future. Recent freezing methods have improved the chances of survival after thawing.
Who Benefits from FET?
Older women do benefit in several ways on account of rounds of IVF treatment for them that can be extremely costly. FET can also eliminate the risk and cost associated with egg retrieval. At the very least, frozen embryo transfer does benefit older women over 40. Each round of IVF that involves egg retrieval as well as fertilization is risky and expensive.
