Is the success rate of IVF pouch collection high?

Understand that in IVF, embryo transfer is usually carried out on the third day after egg retrieval. At this time, the embryo contains 5~8 cells, and blastocyst means that the embryo is cultured in vitro for 5~6 days, reaching hundreds of cells. At this time, implantation in the woman's uterus is called blastocyst transplantation.

There is no doubt that the implantation rate of blastocysts is higher than that of normal embryos, because blastocysts have better grades and faster development. For women whose physical conditions are not suitable for multiple pregnancy, blastocyst transfer can achieve a higher pregnancy rate and reduce the risk of multiple pregnancy.

However, blastocyst transfer is not suitable for all patients, and not all embryos can be transplanted after reaching blastocyst level in laboratory culture. Only 40~50% embryos can develop to blastocyst stage. Blastocysts require higher quality of embryos. For patients with few embryos and poor quality, it is very likely that the blastocyst stage can not be cultivated, resulting in complete annihilation of the embryos. For such patients, it is generally recommended to transplant as soon as possible. Some embryos cannot survive in the laboratory environment, but may survive in the uterus. After all, the uterus is the best environment for embryos to survive and take root.

So whether blastocyst transplantation depends on personal situation, I hope it has reference value for you! ! !
