Is the quality of blastocyst 4bc good?

Speaking of what can directly affect the success rate of IVF, in addition to eliminating problems such as thin endometrium, the embryo is also a very direct impact. When patients encounter embryos 4bc and 4cb, how should they choose to increase the success rate? In fact, experienced people will tell you that whether it is 4bc embryos or 4cb blastocysts, the success rate is the same.

4bc and 4cb embryos are not far apart in terms of success

What do 4cb and 4bc mean?

In order to facilitate the understanding and comprehension of embryos, they are graded. The numbers represent the stage of embryonic development, while letters such as "b" and "c" represent inner cell mass and trophoblast, which are the key distinctions for graded classification.

The meaning of 4bc embryo

The "4" in the 4bc embryo here means that the embryo is in the expansion stage, and the "b" and "c" at the end mean that the inner cell mass is small in number and loosely arranged, and the germ cell squamous epithelial cell layer is composed of sparse cells.

For 4cb embryos, the inner cell mass and germ cells are reversed. The number of cells in the inner cell mass is very small, while the squamous epithelial cell layer is composed of a small number of cells, but the structure is relatively loose. Therefore, the two are similar, but if you make good preparations before transplantation and face it with a good attitude, the pass rate is actually much higher than that of test tube embryos.

Tips:

As for which embryo has a higher success rate, 4bc or 4cb, since they belong to the same level, the pass rate is very similar. Therefore, embryos 4bc and 4cb are at the same starting point, so there is no significant difference between embryos 4bc and 4cb. If they appear at the same time, they can be transplanted together.

Comparison of embryos 4bc and 4cb

There is no significant difference in terms of quality and development time, so there is no need to compare embryos 4bc and 4cb, and patients do not need to worry too much, just do a good job of transplantation.

Both 4bc embryos and 4cb embryos can be transplanted

There is no need to worry about the success rate after embryo test tube transfer, because the possibility of embryo implantation after either 4bc embryo or 4cb embryo test tube transfer is very high. Excessive anxiety will always affect the implantation of IVF embryos, so it is important to take things as they come and seek medical advice.

Past examples of transplantation

It is not necessary to analyze which of the 4bc and 4cb embryos has a higher success rate, because even if you are given high-quality embryos, it does not mean that you will definitely succeed, and conversely, a slightly worse embryo does not mean that you will fail.
