Are all blastocysts of 4bb grade girls?

Everyone has a certain obsession with the birth of a boy or a girl, especially after the test tube transplantation, they will look for various information and ask other sisters. Just now a customer asked: "Is the transplanted frozen embryo 4bb level a boy or a girl?" For a moment, the editor didn't know how to explain it. In fact, the first thing to know is that the probability of having a boy or a girl is only 50%.

Are 4bb embryos usually all boys?

Is the 4bb embryo a boy or a girl?

Some sisters who have transplanted 4bb embryos are curious about whether it is a boy or a girl. In fact, let me tell you that the test tube embryo level cannot tell whether it is a boy or a girl. Whether it is a boy or a girl is determined by chromosomes, so the probability of having a boy and a girl is 50% each.

Embryo level cannot determine whether the baby is a boy or a girl

In fact, there are many legends about the folk customs of giving birth to boys and girls, such as: "a pointed belly means a boy, a round belly means a girl", "sour boy, spicy girl", etc. In short, I don't know whether the chance of embryo 4bb being a boy is high or not. It is more important and happy if the assisted pregnancy can be successful.

There is no direct correlation between the grade of test tube embryos and the birth of a boy or girl, so the probability of embryo 4bb being a boy or a girl is only 50%. If you really want to know the name, you only need to wait for a dozen weeks before B-ultrasound can tell the gender.

Embryos with more than 4bb are high-quality embryos

Embryos cannot determine the sex of the baby. The embryos used for IVF transplantation are test tube embryos that have been shaped into five or six-day-old test tube embryos. The success rate of embryo transplantation is relatively higher than that of fresh embryo transplantation. Of course, it does not mean that pregnancy will be successful if AA-level test tube embryos are transplanted.

The 4 in embryo 4BB represents embryos at different expansion stages. Here it refers to embryos that are already in the expansion stage, and the two Bs here are mainly for quality classification of inner cell mass and trophoblast cells. A 4BB embryo means that it is in the expansion stage and the cell group within the embryo is small in number and loosely arranged. The squamous epithelial cell layer of the trophoblast is composed of a small number of cells with a loose structure. Overall, it is a high-quality embryo. Generally speaking, BB, AA, AB, and BA grade embryos are considered to be of high quality and are more suitable for transplantation during the IVF cycle. They have a very high embryo implantation rate and pregnancy rate, and the probability of twins and ectopic pregnancy can also be relatively reduced.
