When is the most accurate time to check the endometrial thickness? What is the endometrial thickness?

The normal thickness of the endometrium is 0.8-1.0cm. If the endometrium is too thick or too thin, it will directly affect pregnancy. To check the thickness of the endometrium, you can choose to check it 3-5 days after the menstrual period, or you can choose to check it during the ovulation period for close observation.

Endometrial examinations must be done at a set time, and there is only one chance per month. Sometimes, in order to find out the various causes of infertility, it takes 2-3 months. This is not because doctors intentionally make things difficult for patients, but because only one egg matures and is ovulated in a woman's ovary each month, and the endometrium also only reflects the changes of ovulation once a month. In order to actively cooperate with the doctor's examination, it is necessary to understand some information about endometrial extraction.

The uterus is hollow in the middle. The uterine wall is divided into three layers. The outermost layer is the serous layer, which acts as a coating. The middle is a thick muscle with strong elasticity, so the uterine cavity can be large or small, large enough to accommodate a fetus. The inner wall is a thin film called the endometrium. The endometrium is directly affected by the sex hormones secreted by the ovaries and undergoes periodic changes. Before ovulation, the follicles mainly secrete estrogen during development, which gradually thickens the endometrium. After ovulation, the corpus luteum secretes progesterone. At this time, under the combined action of estrogen and progesterone, the glands in the endometrium develop significantly and begin to secrete mucus. If there is no fertilization, the endometrium becomes thinner and the glands collapse before the onset of menstruation, and no mucus is secreted. Then the endometrium of the uterus falls off and menstruation comes. A woman ovulates about 400 eggs in her lifetime, and the endometrium will fall off and regenerate 400 times accordingly. When the fetus is delivered, this layer of endometrium is called decidua, which is discharged along with the placenta, and a new endometrium will grow after delivery.

Since the endometrium changes periodically, if you want to examine the endometrium, you must take samples within the specified time to accurately reflect whether there is ovulation or other abnormal phenomena. The most suitable time is 2-3 days before menstruation or within 12-24 hours of menstruation. If the endometrium taken out is secretory endometrium after pathological examination, it means that ovulation has occurred. If menstruation has occurred for more than one day, the old endometrium has mostly fallen off and the new endometrium has begun to grow. At this time, taking the endometrium for examination often does not get the correct result. Because the ovaries do not ovulate every month, they may ovulate after a month.

Therefore, if no ovulation is found during an endometrial sampling, it does not necessarily mean that the ovaries are not ovulating. In addition to knowing whether ovulation has occurred, endometrial examination can also diagnose other diseases. For infertile women, the endometrium should be checked for tuberculosis. Sometimes patients with endometrial tuberculosis do not have any symptoms and can only be diagnosed by taking endometrium.

The above is the introduction of when to check the thickness of the endometrium. In order to improve the diagnosis rate, it is best to scrape the endometrium 2-3 days before the menstrual period. At this time, the endometrium is thick, and it is easy to take more endometrial tissue for examination by the pathologist. In addition, by taking the endometrium, it is also possible to understand whether the patient has lesions such as fibroids or polyps in the uterine cavity.
