How much is normal pregnancy endometrial thickness?

The thickness of the endometrium is 5 to 10mm when not pregnant. In early pregnancy, the thickness of the endometrium is generally 12 to 14 mm. Because after pregnancy, estrogen levels in the female body will increase, so it will cause the thickness of the endometrium to increase. This situation will also facilitate the implantation of fertilized eggs, which can play a role in protecting the fetus. After pregnancy, there is no need to measure the thickness of the endometrium. Because the endometrium will further proliferate after pregnancy, the decidua will be formed by the corpus luteum of pregnancy. Under the influence of estrogen and progesterone levels, the endometrial glands will also enlarge, the blood vessels will present a state of congestion, and the connective tissue cells will gradually become hypertrophic. At this time, there is actually no way to measure the thickness of the endometrium. Therefore, it is generally not necessary to measure it after pregnancy, but it is necessary to confirm it in the early stages of pregnancy.
