What is the normal thickness of the endometrium?

The uterus is a relatively important reproductive organ for women. The thickness of its endometrium is also within a fixed range, and the thickness of the endometrium also varies depending on the different conditions of women. Therefore, many women are concerned about endometrial thickness. So, what is the normal thickness of the endometrium? Let’s take a closer look at it below.

The endometrium of the uterus is thicker than that of normal people. The thickness of the endometrium cannot determine whether you can get pregnant. Whether or not ovulation occurs is the key to whether you can get pregnant. The normal range is 0.2-1.0 cm.

Proliferative phase: approximately from the 5th to the 9th day of the menstrual cycle, the endometrium is very thin, the glands are sparse, the glandular ducts are narrow and straight, and the glandular cavity surface is flat.

During the 10th to 14th day of the menstrual cycle, the endometrium becomes thicker and wavy, the glands and stroma proliferate significantly, and the number of glands begins to increase.

Secretory phase: From the 15th to the 19th day of the menstrual cycle, which is 1 to 5 days after ovulation, the endometrium continues to thicken and the glands further increase in size and curvature.

Around the 20th to 24th day of the menstrual cycle, which is 6 to 10 days after ovulation, the endometrium shows a high degree of secretory activity, and the curvature and expansion of the glands reach a peak.

In the late secretory phase, the thickness of the endometrium is about 5 to 6 mm.

Premenstrual period: approximately from the 25th to the 28th day of the menstrual cycle, which is 11 to 14 days after ovulation, which is equivalent to the regression period of the corpus luteum. The glands and glandular epithelial cells begin to shrink, degenerate, and secretions dry up, showing a phenomenon of exhaustion, and the thickness of the endometrium decreases by 1/5 to 1/3.

4 to 24 hours before the onset of menstruation, local spasmodic contraction occurs in the intimal spiral arterioles, causing ischemia and necrosis of the intima distal to the spasm. The permeability of the blood vessel wall increases, followed by vasodilation, and blood flows out of the broken blood vessels.

The above is an introduction to the normal thickness of the endometrium. I hope it will be helpful for women to understand. The thickness of the endometrium has a certain value. When it thickens or thins, it is an abnormal condition and requires timely treatment. Therefore, knowing the thickness of the endometrium can effectively detect various abnormal conditions in the body.
