How many days can an embryo survive without implantation?

Key reminder: After the male sperm meets the egg cell, they become sperm-egg fusion. The sperm and egg combine and enter the uterus, which means the fertilized egg has successfully implanted. If the test tube embryo fails to implant, it means that the embryonic development process has failed and the embryo can only survive for about 8 days. The reasons why the test tube embryos fail to implant are: the shedding of the uterine wall in the woman's uterus and certain problems with the bilateral fallopian tubes. The poor health of natural test tube embryos themselves and men is also part of the reason.

We know that at different stages of a woman's pregnancy, we call the fetus differently. The young body that appears in the first two months of pregnancy is called a test tube embryo. Not until the fertilized egg implants successfully will the baby enter its development stage. It is very important for pregnant mothers and fathers to master these knowledge related to pregnancy. Next, let's talk about topics related to test tube embryos. Let's talk about: How many days can a test tube embryo survive without embryo implantation? What is the reason for the test tube embryo not to implant?

How many days can a test tube embryo survive without embryo implantation? We know that test tube embryo implantation means that the test tube embryo successfully enters our uterus, stabilizes in the uterus, and gradually grows into a fetus. If the test tube embryo does not implant, we know that the sperm can only survive 1 to 3 days in the fallopian tubes, and the egg cell can survive for about 1 day. When the male sperm meets the egg cell, they combine into a sperm-egg. The sperm and egg combine to continuously absorb nutrients, process and decompose at the same time, and move towards the position in the uterine cavity. It will enter the uterus about 68 days after fertilization. Once the test tube embryo fails to implant, it means that the embryonic development process has failed and it can only survive for about 8 days.

What is the reason why test tube embryos cannot implant? There are many reasons why test tube embryos cannot implant. Generally speaking, the main reason is that women’s physical conditions are not good. In particular, the shedding of the uterine wall in women's uterus and certain problems in the bilateral fallopian tubes can affect the implantation of the fertilized egg. The quality of natural test tube embryos themselves is not very good, which is also the reason why test tube embryos fail to implant. If a man is in poor health, it is possible that the test tube embryo may not implant.

According to the above, we know that test tube embryo mainly refers to the 2-month stage of preparing for pregnancy. This stage is the critical period for test tube embryo to implant in the uterus. If the test tube embryo does not implant, it means that the embryo development process has failed and the pregnancy is not successful. We need to pay attention to the cause immediately and find out where the problem lies. If it is due to the human body, we need to take good care of our body.
