What to expect during fertility treatment?
Frozen embryo transfer or FET is a fertility treatment where embryos developed in an earlier IVF cycle are frozen and preserved (cryopreservation). Treatments like IVF are a silver lining for couples who cannot have children naturally. However, the low success rate in a single IVF cycle is a great challenge.
When should you consider fertility treatment?
Oct 27, 2017 · A frozen embryo transfer (FET) is a type of IVF treatment in which a cryopreserved embryo created in a previous egg retrieval cycle is thawed and transferred to the uterus. Often, FET uses frozen embryos a gestational parent has from a previous conventional IVF cycle. A cryopreserved embryo can also be a donor embryo.
When to seek fertility treatment?
Frozen embryo transfer (FET) You may undergo a frozen embryo transfer (FET) cycle whenever you have frozen embryos and wish to use them. This may be after the delivery of a child when you wish to come back and use your frozen embryos to grow your family, or it could be after an unsuccessful stimulated in vitro fertilization (IVF) cycle in which you had embryos cryopreserved.
Is FET same as IVF?
A frozen embryo transfer is a little bit different. In this type of cycle, a woman undergoes IVF, her eggs are retrieved and fertilized in the lab, and the resulting embryos are allowed to develop. On day 5 or 6, the embryos are frozen instead of being transferred back into her uterus.
Do you ovulate with FET?
In Natural FET-IVF cycles, the timing of your frozen embryo transfer is determined when you ovulate naturally. However, an hCG shot is typically given to ensure ovulation occurs and progesterone will be used for luteal phase support after ovulation and transfer.
How does FET work IVF?
A frozen embryo transfer (FET) is a cycle in which the frozen embryos from a previous fresh IVF or donor egg cycle are thawed and then transferred back into the woman's uterus.Sep 18, 2020
How long does FET cycle take?
approximately 6 to 8 weeksA FET cycle will take approximately 6 to 8 weeks. A cycle typically begins with 3 to 4 weeks of daily birth control pills to suppress the normal ovarian cycle, as it would lead to ovulation. After the course of birth control, you will need a baseline assessment involving bloodwork and ultrasound.
Why do FET fail?
When an embryo fails to implant, there can only be two logical reasons: the embryo is not good enough (genetically abnormal), or the endometrium is not “receptive” (doesn't allow the embryo to implant) enough.Dec 9, 2021
Can you get pregnant naturally during FET?

FET step by step. An IVF-FET cycle involves just two steps. Simply put, it works as if a conventional IVF cycle was split into two major parts. On the one hand, creating the embryos ( ovarian stimulation, egg retrieval, and fertilization), and on the other, endometrial preparation and embryo transfer.
How long before embryo transfer do you take progesterone?
Additionally, about 3-5 days before the transfer, she has to take progesterone (pills or vaginal pessaries). These medications should be taken from the first or third day of menstruation, that is, at the beginning of the cycle, until the day of the embryo transfer (in total, 10-15 days in a row).

How are IVF eggs fertilized?
Then, they are retrieved through a procedure called follicular puncture or ovum pick-up (OPU), and finally they are fertilized in the lab using the husband's sperm or donated sperm.
What is the treatment for a substituted cycle?
In case of a substituted cycle, the treatment consists of the administration of an estrogen in the first phase and the association of an estrogen and progesterone in the second phase. Both substances prepare the endometrium for implantation, but have no effect on follicular growth or ovulation.
When do embryos thaw?
Embryo thawing. When the embryo transfer day is set, the embryos are thawed considering the day when they were transferred. Simply put, if they were frozen on day 3 of development and you want to transfer them on day 3, they will be thawed on the transfer day.
What is the FET IVF cycle?
There are two kinds of FET-IVF cycles: hormonal support cycles and “natural” cycles. The most commonly performed FET-IVF cycle is a hormonally supported cycle, which is appealing to couples, clinics, and labs because the day of transfer is easy to control and hormonal support is available for any ovulatory problems.
What is a FET test?
FET is often part of preimplantation genetic testing (PGT). You might be able to do FET using untested, "leftover" embryos from PGT. You might have embryos to use because you froze them all to begin with for the testing.
Why is a fresh embryo transfer canceled?
If your risk of OHSS appears to be high before a fresh embryo transfer, it might be canceled. When this happens, all the embryos will be cryopreserved. Cancellation might be necessary because pregnancy can exacerbate OHSS. It may also take longer to recover from OHSS if you’re pregnant.
What is frozen embryo transfer?
A frozen embryo transfer (FET) is a type of IVF treatment where a cryopreserved embryo created in a full IVF cycle is thawed and transferred to a uterus. FET typically uses “extra” embryos a couple has from a previous conventional IVF cycle. A cryopreserved embryo can also be a donor embryo.
How long after egg retrieval can embryos be frozen?
To avoid this outcome, all embryos are cryopreserved three to five days after egg retrieval. The next month or in the month after, when the endometrium has had a chance to form without the influence of ovarian stimulating drugs, a frozen embryo transfer can take place.
When is a biopsy done for embryo transfer?
This is done through a biopsy on day three or five post-fertilization, post egg retrieval. Sometimes, the results get back in time to do a fresh embryo transfer. However, if a day five biopsy is done, or the genetic testing is complex and requires more time, all embryos that were biopsied will be cryopreserved.
When is an embryo transfer scheduled?
Instead, the embryo transfer is scheduled based on when ovulation naturally occurs. The timing of the embryo transfer is crucial. It must occur a particular number of days after ovulation. As mentioned above, that day will depend on whether the embryo was frozen on day 3 or day 5 post-egg retrieval.

What does FET stand for in IVF?
What is FET. FET stands for frozen embryo transfer. In in vitro fertilization (IVF) treatment, patients who have had previous rounds of IVF resulting in healthy embryos that were frozen can opt to use those frozen embryos instead of fresh ones.

On the one hand, creating the embryos (ovarian stimulation, egg retrieval, and fertilization), and on the other, endometrial preparation and embryo transfer. The parties involved in each party can be the same from beginning to end, or be different, as in the c…
Natural vs. Stimulated Cycle
- The treatment explained above refers to what we usually know as stimulated IVF cycle. The reason for this name is due to the fact that we are stimulating or replacing the natural menstrual cycleof the woman using artificial hormones, including GnRH analogs, estrogen, and progesterone. By doing this, we simulate the behavior of a natural cycle but controlling it to enha…
Success Rates
- The chances of getting pregnant after a FET depend highly on the quality of embryos after going through the thawing process, and the particularities of the IM's uterus. The embryo vitrification technique reaches high survival rates. Thus, individualizing the endometrial preparation protocol on a case-by-case patient and keeping a close eye on how the uterine lining progresses is crucia…
Advantages of Using Frozen Embryos
- According to Dr. Gorka Barrenetxea, Obstetrician & Gynecologist, there is a huge difference between conventional embryo freezing procedures and embryo vitrification. With the latter, the risk of late Ovarian Hyperstimulation Syndrome(OHSS) decreases, which is a major advantage. Also, in the word of Dr. Barrenetxea, the success rates with frozen embryos are actually higher. …
Cost
- The cost of embryo thawing for use in a FET cycle is cheaper than a complete IVF cycle, given that there is no need for the patient to undergo ovarian stimulation and in vitro fertilization again. The cost, however, varies from clinic to clinic.
FAQs from Users
