After obtaining the test tube embryo grade results, everyone may be confused about the above data and don't know what 4bc, 4cc, and 4BB mean. In fact, it is a way of expressing the test tube embryo grade. Taking "4BB" as an example, it is a mark of high-quality embryos and can be transplanted.

What does a "4bb" embryo mean?

The "4" in embryo 4BB refers to embryos at different expansion stages. Here it refers to embryos that are already in the expansion stage. Then "B" and "B" are mainly used to classify the quality of inner cell mass and trophoblast cells.

Generally speaking, BB, AA, AB, and BA grade embryos are considered to be of high quality. They are the most suitable types of embryos for transplantation during the IVF cycle. They have very high embryo implantation and pregnancy rates, and the probability of twins and ectopic pregnancy can also be relatively reduced.

Some netizens responded to the question "Are 4BB embryos good?": The blastocyst level is good, and the pregnancy success rate is very high; I have 2 4bb test tube embryos, and I am now 29 weeks pregnant; the quality is good, so I can rest assured and wait for the arrival of the babies!

Whether from the perspective of my own test tube embryo grade standards or some classic cases of my sisters in the past, this level is of better quality embryos with a high pass rate. Take good care of your body and I wish you a successful test tube baby.

What is the success rate after 4bb embryo test tube transfer?

Embryos above 4bb are high-quality test tube embryos, with high embryo implantation rate and pregnancy rate. Don’t worry if you are wondering about the pass rate. The pass rate is basically the highest among embryos. Since the higher the grade of the test tube embryo, the higher the pass rate, of course. Don’t worry, the baby is already in your belly!

4bb embryo transfer classic case

I had previously transferred two 4bb embryos, and both implanted. Don't worry too much during transplantation. You must know that this is already the best grade among embryos. You must carry out transplantation in the best condition, so that the chances of success will naturally be greater.
