When is A frozen embryo transfer done in IVF?

A frozen embryo transfer tin can be done at any point in the hereafter if you have already undergone an in vitro fertilization (IVF) bicycle that generated usable embryos.

In other words, it tin can happen as soon every bit the side by side cycle after your egg retrieval or several months (or years) afterward.

How long does a frozen transfer cycle take?

A frozen embryo transfer bicycle lasts approximately 3-4 weeks. The first two weeks will fix your uterine lining for implantation. One time your lining is ready, you will begin progesterone supplementation at some signal in the 3rd week.

The embryo transfer then takes place later 3 or v days of progesterone support.

What is the timeline for a frozen embryo transfer? (Day by day)

Now allow's pause down the steps of a frozen embryo transfer (FET) bicycle, solar day past 24-hour interval.

Step 0: Prep Piece of work

If you are using your ain eggs/embryos, you will kickoff need to undergo an IVF cycle.

The IVF process and the freezing of any usable embryos normally take 2-3 weeks. You can read my post on The IVF Cycle Timeline to learn more.

If you already take embryos frozen, speak with your medico to make up one's mind if you are eligible to brainstorm a FET right away.

Many fertility specialists will accept you come back for a consultation to decide if yous should do a medicated FET cycle vs. a natural FET cycle.

Y'all may also need a uterine cavity evaluation (saline sonogram or a hysteroscopy) or a mock transfer before proceeding.

In one case everything is cleared, you will exist instructed by your fertility dispensary to phone call or electronic mail to written report wheel day 1 of your menstruum.

30 day calendar showing the timeline of an FET cycle

Day ane:

Day 1 refers to the first day of your period. After informing your dispensary, y'all will be scheduled to come in on Day ii,iii or four of your cycle to potentially begin the FET bicycle.

24-hour interval ii,3 or 4:

On Days 2-4 of your menstrual cycle, you will come up in for forenoon monitoring, a transvaginal ultrasound scan, and claret work.

If the ultrasound looks normal and your hormone levels are "baseline," you lot will begin your FET cycle that day.

If you are doing a medicated FET bicycle:

You will begin estrogen supplementation on this day.

The estrogen tablets practise two things: It thickens the lining of your uterus and prevents an ovarian follicle from growing.

You will come dorsum in about a week or so to check on the progress of your lining.

If you are doing a natural cycle:

You won't be starting any medications. Yous will simply come back in about a week or so to bank check on the progress of your lining.

Days ~10-14:

At your 2nd morning monitoring visit, your lining should exist increasing in thickness.

The goal is to get your lining to ~ 7mm in size.

If yous are doing a medicated bike:

If your lining is growing as expected, you will be given a start appointment for progesterone supplementation.

This usually involves intramuscular progesterone injection with or without progesterone vaginal suppositories.

If you are doing a natural wheel:

Your lining should be thicker, and you should have a ascendant ovarian follicle growing.

Your reproductive endocrinologist may wait for your trunk to brainstorm the ovulation process (aka, your blood tests show that your LH hormone is surging).

In this case, your doctor may or may not have you have a trigger shot to kickoff ovulation.

Day ~15-18:

At some point later on the two-week mark, you volition begin progesterone.

If you are doing a medicated FET wheel:

You volition start intramuscular progesterone shots in one case your doctor has deemed that your lining is appropriate.

You lot will administer the progesterone injection twice on the starting time 24-hour interval and then once every day after that.

The embryo transfer process will then be scheduled:

on the 6th day of progesterone injections (if yous are having a blastocyst stage embryo transfer)
on the fourth day of progesterone injections (if y'all are having a cleavage stage Day 3 embryo transfer)

If you lot are doing a natural FET cycle:

Yous will brainstorm progesterone suppositories on the day after your trigger shot (or the 24-hour interval after yous ovulate).

The embryo transfer procedure volition then be scheduled:

on the sixth day of progesterone suppositories (if you are having a blastocyst transfer)
on the fourth day of progesterone suppositories (if you are having a cleavage stage Solar day 3 embryo transfer)

Day ~19-24:

This is the day of the embryo transfer. It is a simple procedure that shouldn't take more than twenty minutes.

Yous will be expected to come with a full bladder, which will help visualize and guide the catheter containing the embryo into your uterus.

24-hour interval~28-32:

You lot will and then accept your showtime pregnancy test no sooner than ix-xi after the transfer!

How many days after FET does implantation occur?

We believe that an embryo will implant in the outset 24-48 hours after the FET. You probable won't experience annihilation either way except for very mild cramping.

Can I do a pregnancy test eight days afterwards embryo transfer?

We highly recommend waiting at least ix-eleven days after the transfer to avert getting a simulated negative.

Before that time, the homo chorionic gonadotropin, aka hCG levels are non loftier enough to yield a positive abode pregnancy test.

Information technology is much improve to get a quantitative hCG blood exam at your physician'south office after 9-11 days.

How many weeks pregnant are yous after IVF frozen transfer?

Y'all are approximately two weeks and 5 days pregnant on the day of a blastocyst embryo transfer (assuming that it works).

Past the time y'all have a positive pregnancy test ~nine days later, you will be approximately iv weeks meaning.

What are typical five day frozen embryo transfer success rates?

Success rates vary among patients based on age and diagnosis, but a genetically tested blastocyst can have a success rate of fifty-60%.

However, the success charge per unit of an untested frozen embryo transfer can go every bit low as 20-30%, decreasing with increasing maternal age.

Here are some recent studies: [1] [ii] [3]

Check out my post on Embryo Biopsy to see if you are a good candidate for genetic screening.

Why practice frozen embryo transfers fail?

Unfortunately, we don't ever know why some embryo transfers neglect.

In general, at that place can be an embryo quality issue, an implantation failure, or other endometrial lining issues that we don't quite understand yet.

Preimplantation genetic testing can help command for numerical chromosomal abnormalities, but it cannot test for all types of genetic conditions that can exist.

What can you do after embryo transfer to increase success rates?

Unfortunately, there is non a lot that y'all can do to ensure a successful pregnancy.

You have already done everything within your ability. The rest is up to the embryo.

If y'all are on progesterone supplementation, practise non stop taking information technology until your doctor tells you to exercise and so.

You do not need bed residual. Too, information technology is a good thought to avoid any increased temperatures for the kickoff 1-2 weeks following the transfer.

In addition, you should attempt to consume a healthy diet and stay well hydrated.

Are FETs better than fresh embryo transfers?

Information suggests that frozen embryo transfers are better than fresh embryo transfers in certain patients, such as those who have a high response to ovarian stimulation.

However, many studies take shown that pregnancy rates and live nascency rates are like for many patients.

With that said, many patients are non good candidates for a fresh embryo transfer.

Bank check out my mail service on Freeze-All IVF cycles to learn when you should freeze your embryos, and my other post on the disadvantages of frozen embryo transfer cycles to assistance y'all make an informed decision.

Determination

You now understand the FET bike timeline as it relates to an IVF handling cycle.

FETs are a dandy way to provide flexibility in planning the timing of your pregnancy, as any generated embryos can be stored indefinitely for future utilize.
