Blastocyst transfer

What is a black cell?

Fertilisation of an egg from a cpematozoid in the human body is formed by a cell and its release from an ovum (ovulation), a fopemippa the union of a single zygote (zygote), separating the genetic epithelium of the cepmatozoid and the egg of the zygote. If this zygote is to be tested, it will be present in the human embryo. Quando il batteria è di 12-16 litri, sarà il pulsante “mopyla”. Five to six days after fertilization, the embryo is born, and the female breast is injected into the placenta. Hvis denne er, en embryo er en “svart celler” og det er den første gang i bud fra differentiering - det har divideret i två typer av tissuer, två typer av tåttyper, två typer celler og en stranssac. Tpofe, a. A human body, a fertilized egg in the fallopian tube, is close to the ovary. The cause of the disease is to be found in the mother's mother's body in the form of a cold cycle, which is in the category of “mopyla”. A toxin a mother cell appears every two days, before the cell enters the cell. A blacocyte is implanted in the endothelial mucosa from the fifth or third day of cold ovulation, so that it can be born again. (placenta), this will sound like our pacifier in fetishy.

What is the cultivation at the blastocyst stage?

This is the method by which fertilized eggs, laid in permanent embryos, are incubated in an extension of 120 hours in specific pediatric cells with the optimal cell Cellusion. A prolongation of the biological potential in vitro means that the “other” is not a biological potential, and from the point of view — the length of time It leads to the emergence of a clear picture of genetic mutations.

The blastocyst transfera la transfer à l'uterus d'un embryo matré dans les conditions laboratoire jusqu'à la cinq jours après fertilizació, a la fase en ce que l'embryo s'a la cavity uterique dans la corps de l'homme. This approach is considered one of the most modern and effective in vitro practice.

When is blastocyst transfer recommended?

• In couples with previous embryo transfer failures on day 2—3;
• När planlagt genetic testing of embryos (PGT);
• In the case of strategies for single embryo transfer (eSET);
• At freeze-all protocollenwhen the transfer is postponed to the next cycle.

How is the process going?

1. Fertilisation: a standard IVF or ICSI procedure is performed in the laboratory.
2. Cultivate the embryos to day 5.
3. Selection of the best blastocyst: in morphology and dynamics of development.
4. Preparation of the uterine lining: A natural or hormonally regulated cycle.
5. Trasferimento: Through a thin catheter, the blastocyst is inserted into the uterine cavity.
6. Luteal phase support: taking progesterone and other medications.
7. Testê ducaniyê: Testek xwînê piştî 7-10 rojan.

Advantages of blastocyst transfer

✅ Higher chance of implantation
Embryos that have reached the blastocyst stage have gone through several critical stages and have a greater potential for successful implantation.

✅ Better embryo selection
Cultivation up to day 5 allows a more precise selection of an embryo with the best characteristics — morphology, development, dynamics.

✅ Lower risk of multiple pregnancy
Allowing a transfer of only one (or a maximum of two) high-quality embryos without lowering the chance of success.

✅ Synchronization with the uterine environment
With a natural conception, the embryo enters the uterus precisely as a blastocyst. Therefore, the transfer at this stage is biologically close to natural conditions.

The biggest risk is that not all embryos reach the blastocyst stage, especially with a smaller number of eggs or in old age. However, those who reach, have a higher chance of success.

Therefore, a decision to culture up to day 5 is always made individually — according to the number of eggs, age, quality of embryos and other medical factors.

In our laboratory, blastocyst transfer is performed with high precision and selection of the best embryos, thanks to modern monitoring systems and customized protocols.

Frequently Asked Questions

1. Is blastocyst transfer better than that of day 3 embryos?
Not necessarily for all patients. A blastocyst transfer is more appropriate when there are more fertilized eggs, as it allows for better selection. With a smaller number of embryos, a transfer on day 3 may be more appropriate. The decision is individual and is made jointly with a doctor and an embryologist.

2. Do all embryos reach the blastocyst stage?
No. Some embryos stop developing between day 3 and day 5. This is a natural process and part of selection — those who reach a blastocyst are likely to have a higher implantation potential.

3. Does blastocyst transfer increase the chances of pregnancy?
Yes, in many cases — blastocysts have a higher chance of implantation because they are more developed and selected.

4. Is blastocyst transfer also possible in frozen embryos?
Ja. Very often, blastocysts are frozen (on day 5 or 6) and transferred to the next prepared cycle. A frozen transfer often leads to the same or even better results, especially when the uterine environment is well prepared.

5. Is there a risk of multiple pregnancy in blastocyst transfer?
The risk is lower because it is often transferred only one blastocyst (eSet). However, in the transfer of two blastocysts, there can be twins - so the choice of the number of embryos is important and is discussed in advance.

6. What happens to the rest of the blastocysts that are not transferred?
If they are of good quality, freeze (vitrify)a se puede usar en los ciclas futuro - en caso de la necessario de transferencia y para un segundo niño.

7. What is the feeling during the transfer?
Blastocyst transfer is painless and quick procedure, performed without anesthesia. Most patients describe it as a mild sensation, similar to a gynecological examination.
