What is FET and who is it for?
FET is for patients who have already had IVF treatment and have frozen embryos as a result. This may be because they had surplus good quality embryos available after having a fresh embryo transfer, or because all embryos were frozen in that cycle.
How does FET work?
The patients’ embryos will be thawed and placed into the uterus at the optimum time in the woman’s cycle to try to achieve a pregnancy. This may be in line with her natural cycle or within a medicated cycle to help time the treatment.
The patient will be scanned at certain points during their cycle, which will determine when the embryo should be thawed and replaced. Medications may be supplied to help support the lining of the womb to be as receptive to the embryo as possible.
Two weeks after the transfer, the patient will perform a pregnancy test to determine whether implantation has taken place. If the test is positive, an ultrasound scan will be arranged to determine the viability of the pregnancy. If the result is negative, the patient will withdraw the medication and a period will occur.
What are the features and benefits of FET?
FET allows patients to have attempts to conceive without the need to have a full cycle of treatment. This helps to reduce interventions, appointments and cost.
Success rates and statistics of FET
Success rates of FET is comparable to fresh transfers. As with all IVF treatment, success rates will be dependent on patient and embryonic factors and hence will vary between patients.
