The best time to measure endometrial thickness

The normal endometrial thickness of women is generally 2-10mm, but there will be different changes in different stages. If female friends find that there is abnormal endometrial thickness after pre-pregnancy physical examination, they need to receive corresponding treatment in time, otherwise it will affect future fertility. So, when is the golden time to measure the thickness of the endometrium?

If women want to check the thickness of the endometrium, the best time is generally recommended to do a transvaginal B-ultrasound test three days before the menstrual period. The thickness of the endometrium seen at this time will be thicker. Because at this time, the estrogen and progesterone have basically reached their peaks and stimulated the endometrium to proliferate. At the same time, hormone withdrawal will occur, causing the menarche. Therefore, the endometrium thickness at this time is the thickest in the entire menstrual cycle, usually around 10-12mm. If it is less than 8mm, it is considered to be too thin.

There is no uniform standard for the thickness of the uterine wall. It will change with the changes in the menstrual cycle. Generally speaking, it is normal to change from one millimeter to two or three centimeters. From the follicular phase to the ovulation phase, the thickness gradually increases from millimeters to one or two centimeters. Finally, it falls off to cause menstruation, and the endometrium returns to millimeters. Therefore, as long as it conforms to normal regularity, the uterine wall is normal.

The uterine wall is mainly examined by color Doppler ultrasound, MRI, CT scan, and B-ultrasound. If the thickness of the endometrium is within the normal range, it is not a disease. If the echo is uniform, there is basically no problem and it is a manifestation of a normal uterine wall. If there are uneven echoes or cyst-like objects in the uterine wall, or there is rich blood in the uterine wall, you should be alert to whether there are symptoms such as common uterine intrauterine polyps, submucosal uterine fibroids in the uterine wall, or endometrial cancer, trophoblastic disease.
