Every day intramuscular progesterone is included later in the cycle.Ĥ. Towards the beginning of the FET cycle, hormonal (oestrogen) infusions are utilized to set up the uterine covering and are regulated just once every three days. A FET cycle is simpler: FET cycles for the patients considered are simpler because of the fact that the couple needn't bother with medical procedure (the egg recovery) or anaesthesia. FET- IVF cycles are less expensive than a fresh IVF cycle: This is because the costs of both prescription and treatment in FET cycle are not the same as in a fresh IVF cycle.Įxpenses of FET treatment are reduced due to factors such as fewer doctor visits required as compared to a fresh IVF cycle, less medication cost, no requirement for egg recovery, insemination, or embryo development.ģ. The innovation of the vitrification process has resulted in high rates of successful pregnancies with single egg retrieval and sperm collection cycle.Ģ. In case the first fresh IVF cycle fails, frozen embryos provide a chance of attempting again for a new cycle without taking ovulation stimulation medicines and undergoing egg recovery. Frozen embryos provide couples with additional IVF opportunities: Having frozen embryos provide the patients undergoing IVF treatment multiple chances for successful conception from a single egg and sperm recovery cycle. Why is frozen embryo transfer recommended and used?ġ. Now that we have learnt the basics of frozen embryo transfer, let’s dig deep to get further insights about FET. In recent times, new innovations such as “vitrification” which is a fast freezing process, has incredibly improved the results from cryopreserved embryos.Īccording to the data, patients who utilize solidified embryos have equivalent or higher conception rates than those from fresh IVF cycle. However, earlier techniques resulted in excessive solidification because of ice covering formation on the embryo, rendering it unproductive. Talking about the history of FET, cryopreservation has existed for a long time. The point to be noted is that frozen embryo can be from a female’s own first IVF cycle or can also be a donor embryo. The process of frozen embryo transfer is almost same as of a traditional IVF treatment with the exception that in IVF treatment fresh embryos are used whereas in FET, additional embryos developed in previous IVF cycle are used.įET has proved to be a great advancement in the field of assisted reproductive techniques. These cryopreserved embryos are defrosted and transferred to a female’s uterus to help her conceive a pregnancy. These frozen embryos can be used in subsequent cycles if the first IVF cycle fails.įrozen embryo transfer or FET is a fertility treatment where embryos developed in an earlier IVF cycle are frozen and preserved (cryopreservation). So, in modern days the IVF specialists recommend the couples to go in for embryo freezing of the additionally developed embryos during the initial IVF cycle. However, the low success rate in a single IVF cycle is a great challenge. Treatments like IVF are a silver lining for couples who cannot have children naturally.
