What is blastocyst culture?
An embryo cultured in the lab until day 5 or 6 reaches a stage of development called blastocyst. The culture of the blastocyst enables the selection of embryos with the highest implantation and transfer potential, thus increasing the clinical pregnancy rate, reducing the high-order multiple pregnancy rate, and improving the implantation rate.
Why blastocyst culture?
- Embryos with the selection during a blastocyst culture may have a higher chance of implantation.
- The well-known fact is that not every embryo can develop further after the transfer and achieve pregnancy. To increase the chances of pregnancy and revive some embryos whose growth has already stopped, many embryos at the 4 to 8-cell stage are being transferred.
- The chance of becoming pregnant rises with the number of embryos transferred, but there’s also a noticeable rise in the likelihood of getting multiple pregnancies, including higher-order multiple pregnancies.
- Assume that blastocyst culture will allow us to choose the embryos. In that scenario, we can increase the chances of getting pregnant while transferring fewer embryos. The probability of multiple pregnancies can be considerably decreased.
- Additionally, we have to perform a culture of the blastocyst and transfer the normal blastocyst for those patients who desire preimplantation genetic testing PGS/PGD using the PGT-A, PGT-M, or PGT-SR technique.
When is Blastocyst culture recommended?
It is recommended that blastocyst culture be performed on all women undergoing IVF. Blastocyst culture is recommended for each patient for whom embryo selection is practical. If there are indeed few embryos, you should contact your doctor before deciding whether to proceed with blastocyst culture.
Who Can Benefit from Blastocyst Culture?
The following women may benefit from blastocyst culture:
- A comprehensive history of unsuccessful IVF cycles.
- Preparing for a single pregnancy.
- An earlier miscarriage history.
What is the process of Blastocyst culture?
Embryos are developed in an aseptic lab with rigorous controls over temperature, light, humidity, and pressure. Special culture media are used for the growth of the embryos, which are appropriate to facilitate their development to the blastocyst stages. The human body’s ideal conditions are emulated in the growth of the embryos in carefully regulated atmospheres.
Does the transfer of blastocyst have any disadvantages?
Not every clinic uses blastocyst culture. Successful blastulation requires excellent quality control and ideal laboratory culture conditions.
The possibility exists that none of the embryos will develop into blastocysts and the embryo transfer process is then cancelled. This usually is a sign that, in good IVF centers, none of the embryos was probably good enough to make it to a blastocyst, and performing a day three transfer would also most likely not result in a pregnancy.
After the first embryo transfer in the next cycle, fewer or no extra embryos may freeze since fewer embryos develop into blastocysts. However, a freeze may not be necessary after all, as blastocyst transfers have higher success rates than day three transfers.
Should blastocyst transfers be performed on all patients?
For women undergoing their first IVF cycle in particular, it might be preferable to transfer a day 3 embryo, depending on variables including age, medical history, and the quantity and quality of embryos.
