Frozen Embryo Transfer (FET)
A frozen embryo transfer (FET) is a procedure of IVF in which frozen embryo from a previous IVF cycle is thawed or warming of embryos is done and transferred into the endometrium. FET has high effective success rate in patients who are not able to conceive with repeated IVF failure.
FET – IVF cycles can be two kinds depending on the patient’s condition and medical history:
- Hormonal support cycles – is where estrogen and progesterone are given to thicken the endometrium; and
- Natural cycles – The timing of the frozen embryo transfer will be determined in the natural cycle as HCG shot is given to trigger ovulation, and progesterone will support the luteal phase after ovulation and embryonic transfer.
