How thick is the endometrium during pregnancy?

After pregnancy, certain organs of the female body can be tested to reflect the condition of the fetus, and the endometrium can achieve this purpose. Pregnancy is a big deal and has received a lot of attention from many families. They are very concerned about the condition of the pregnant woman, especially the thickness of the uterus. So, what is the thickness of the endometrium during pregnancy? Let’s take a closer look at it below.

The fertilized egg absorbs nutrients and oxygen from the fluid secreted by the fallopian tube and continues to undergo cell division. At the same time, the fertilized egg gradually moves toward the uterine cavity. When it arrives at the uterine cavity 3-4 days later, it has developed into a multi-cell entity, shaped like a mulberry, so it is called a morula. The morula continues to divide in the uterine cavity to form a blastocyst, which enters the endometrium about 6-8 days after fertilization. This process is called implantation or planting.

5-6 days after fertilization, the fertilized egg develops into a late blastocyst and implants through three processes: positioning, adhesion and invasion. The late blastocyst first approaches the endometrium, adheres to the endometrium and begins to differentiate. The differentiated trophoblast cells penetrate and invade the endometrium, the inner 1/3 of the myometrium and the blood vessels. The blastocyst is completely buried in the endometrium and covered by the endometrium. Implantation is now complete.

At present, the mechanism of embryo implantation has not been fully elucidated, but the factors for successful embryo implantation include high-quality embryos, receptive endometrium and a suitable endocrine environment. When the fertilized egg implants, the woman is generally in the secretory phase of the endometrium, at which time the thickness of the endometrium is between 5-10mm.

Women must do a good job of pre-pregnancy check-up. An endometrium that is too thin or too thick is not conducive to the implantation of the fertilized egg and will directly affect pregnancy. If a woman has an abnormal endometrium, she must wait until treatment is done before becoming pregnant. Women should also pay attention to maintenance after pregnancy. Once abnormalities such as endometrial abnormalities are found during pregnancy, they need to seek medical attention in time to avoid affecting the development of the fetus.

After pregnancy, the endometrium undergoes certain changes. The endometrium will be thicker than before pregnancy, ranging from about 10-12mm. The thickening of the endometrium can provide some protection for the fetus.

The above is an introduction to the thickness of the endometrium during pregnancy. I hope it will be helpful for pregnant women. The thickness of the endometrium is not fixed and varies greatly depending on the physical constitution of different women. It is necessary to go to the hospital for testing and then combine other data to fully understand the condition of the pregnant woman. The specific data needs to be communicated with the doctor to know.
