Blastocyst transfer success stories

Most clinicians now believe that transferring better-developed embryos i.e. those that have reached the blastocyst stage makes pregnancy more likely. Under the microscope, a blastocyst is markedly different to a day-3 embryo.

Transferring blastocysts can make things more straightforward for implantation. In non-IVF reproduction, a day-2 embryo (usually comprising four cells) will still be rolling down the fallopian tube towards the uterus. Putting a blastocyst directly into the womb on day five or six is an easier prospect for the now highly receptive uterus. Also, genetic testing such as PGD is more accurately carried out on blastocysts.

The key point about blastocysts is that multiple births are less common than with younger transfers. The transfer of one good-quality blastocyst is often recommended. In the past, clinics might transfer up to four day-3 embryos and hope for the best. Blastocysts allow for more informed choices and better control over outcomes. Speaking of which, it’s time to work out your IVF due date!

Single or double embryo transfer

In cycles of in vitro fertilization (IVF), it is routine to stimulate the female’s ovaries to produce multiple eggs to use for fertilization. In many cases, we obtain more than one good embryo to consider for transfer to the uterus. The availability of multiple good embryos allows us to grade them and then choose the best for transfer. It also brings up a common dilemma.

The urge to transfer two embryos is sometimes based on the subtle fear that the embryos will somehow be wasted. Embryos not transferred can remain frozen, and frozen embryos can remain viable for 20 years or more.

The intended parents often have the freedom to choose whether to transfer one or two embryos. But they should not make this decision lightly or naively. They should make this decision only after carefully considering the risks to infants and mother, their desire for multiple children, their finances and their clinic’s implantation rate.

Types of embryo transfer

In order to extract and fertilize the eggs during IVF, doctors generally follow the same process every time. Once fertilization has occurred, there are a few different options available for embryo transfer:

Fresh embryo transfer: Once eggs have been fertilized; they are cultured for 1-2 days. The best embryos are chosen to transfer directly to the woman’s uterus.

Frozen embryo transfer: Any healthy embryos that were not used in the first transfer can be frozen and stored for future use. These can be thawed and transferred to the uterus.

Blastocyst embryo transfer: If many healthy embryos develop after the fertilization, it is common to wait to see if the embryos develop into blastocysts., blastocyst embryo transfer has a higher success rate than the standard embryo transfer on day 3. However, another recent study suggests that it may pose risks later in pregnancy and should not always be recommended.

Assisted hatching (AH): the process of assisted hatching weakening the outer layer of the embryo before it is transferred to the uterus does not improve pregnancy and implantation rates in women who are having fresh embryos transferred. The researchers noted, however, that women having frozen embryos implanted do benefit from having their embryos treated in this way.

Success rates of embryo transfers

The rate of success for embryo transfers may vary based on the transfer method used. There is no statistical difference between using fresh and frozen embryos. Embryo transfers using fresh embryos had a 23 percent pregnancy rate, whereas frozen embryos had an 18 percent pregnancy rate.

The study showed that frozen embryos could also be used for additional embryo transfers where fresh embryos could not. If the chance for pregnancy is low, doctors may consider freezing additional embryos for a second attempt at embryo transfer at a later date. Individual success rates can vary and may depend upon the cause of infertility, ethnic backgrounds, and genetic disorders.

After embryo transfer

  1. Bed rest for 4 hours is advisable after embryo transfer. You can resume normal activity at home because there is no clinical evidence that prolonged bed rest increases pregnancy rate.
  2. After discharge from the hospital, you can resume your daily activity. But do not do heavy chores, like lifting heavy objects, carrying a child or performing strenuous exercise.
  3. Sexual intercourse is not advisable before pregnancy is confirmed, because the period of implantation is rather unstable.
  4. There is no particular food restriction. It is best to use less or no oil at all in food preparation (use plant oil if you must), eat high fiber diet and you can steam, boil, toss, broil or stew them.
  5. Ovarian hyperstimulation syndrome (OHSS): In rare instances, some patients can develop this problem after receiving ovarian stimulation drugs, manifesting as mild abdominal discomfort, abdominal fullness and scanty urine. In serious cases, there may be ascites, abdominal pain and fullness or breathing difficulty. It may take several days to recover in mild cases, but admission for observation may be necessary in severe intances. Symptoms may be prolonged for weeks in cases of pregnancy. Please return to the hospital for treatment if you experience severe abdominal fullness, breathing difficulty or decrease urine output after embryo transfer, It is prudent to eat more protein (animal sources like egg, low fat milk, lean meat, chicken or sparerib soup but with oil removed; or plant sources like rice, noodle, beans or bean products - tofu, soybean milk, vegetarian based meat, green or red beans, cashew nuts or walnuts) to alleviate these symptoms.

Abstain from vigorous exercise

Don’t restrict yourself from your routine activities but lifting heavy weight post embryo transfer is not a good idea. There is no a strict measure of how much to lift and twist but avoiding heavy weight and rigorous exercise should be avoided. Your ovaries are likely still enlarged and tender at this point and need to be protected, so a big NO to hard work out.

Take it Easy: Avoid Extreme of Temperature

Avoid heat completely. Hot baths, hot yoga, sauna, heating pads or anything that can raise the temperature of your uterus and should be strictly avoided after embryo transfer.

Expect the Worst and Wait for the Best

No IVF cycle guarantee pregnancy so you should keep yourself ready for all possible circumstances after the two weeks wait. This wait can make or break and you can’t deny this. But you should follow the above tips to keep your pregnancy chances higher after embryo transfer.

10 common questions about blastocyst transfer success stories

1Are blastocyst transfers more successful?
Most clinicians now believe that transferring better-developed embryos – i.e. those that have reached the blastocyst stage – makes pregnancy more likely. Under the microscope, a blastocyst is markedly different to a day-3 embryo
2How long does it take for a blastocyst to implant?
about 6 to 10 days Human blastocysts should hatch from the shell and begin to implant 1-2 days after day 5 IVF blastocyst transfer. In a natural situation (not IVF), the blastocyst should hatch and implant at the same time - about 6 to 10 days after ovulation
3What happens after blastocyst transfer?
Day by Day After a 5-Day Transfer Day 1: The blastocyst begins to hatch out of the shell – this is called hatching. The cells will carry on dividing throughout this process. Day 2: The blastocyst continues hatching and begins to attach itself to the uterine lining – this is an incredibly important part of the process
4How many fertilized eggs develop blastocyst?
benefits of blastocyst transfer with IVF Historically, if a woman has 15 eggs retrieved, an average of 10 would fertilize after one day. It is impossible to determine at this point which of these 10 are most likely to implant and develop into a baby
5Is blastocyst transfer better?
The chances of getting pregnant after blastocyst transfer are very high. ... However, blastocyst culture does not provide the same advantages for all women. Those with a low egg count and quality may indeed benefit from a day-3 transfer, in which the embryos are inserted in the mother's uterus at an earlier stage
6How many days after blastocyst transfer can I test?
IVF Pregnancy Test Your doctor will likely schedule a blood test 10 to 14 days after the egg retrieval. The blood test will detect and measure the hormone hCG, the “pregnancy hormone.”
7Is a hatching blastocyst more likely to implant?
An embryo reaching the blastocyst stage has an increased chance of implantation as opposed to a day 3 embryo (all things being equal regarding a healthy uterus). It is believed that the improved implantation rates following a blastocyst transfer are due to selection of the "best" embryos
8How soon can you test after 5 day blastocyst transfer?
Don't test early, or expect pregnancy symptoms. Wait for 14 days after your transfer (12 after a day-5 transfer), then test.
9Is bed rest necessary after embryo transfer?
When IVF first started, patients were rested strictly flat on their backs for 24 h. Subsequently embryo transfer became an outpatient procedure, with most women having only a few minutes rest. ... A study by Botta and Grudzinskas (1997) found that 24 h of bed rest after embryo transfer did not influence the pregnancy rate
10Can I bend down after embryo transfer?
You can't knock them out, but you also can't make them stick." Many of my patients worry the most about what they can and cannot do after an embryo transfer. ... Yes, you should relax and take it easy after an IVF embryo transfer.
