When should I check the thickness of the endometrium?

Many people have difficulty getting pregnant because the endometrium is too thin or too thick, so doctors will recommend checking the thickness of the endometrium. However, sometimes, doctors will ask patients to wait for a while before checking the thickness of the endometrium. This is because checking the thickness of the endometrium is not possible at any time and requires time. So when is it necessary to check the endometrial thickness?

Endometrial examinations must be done at a specified time, and there is only one opportunity per month. Sometimes it takes 2-3 months to identify the various causes of infertility. It is not that the doctor intends to make things difficult for the patient, but that a woman's ovaries only mature and ovulate once a month, and the endometrium also reflects the changes in ovulation only once a month. In order to actively cooperate with the doctor's examination, it is necessary to understand some information about endometrial removal.

There is a hollow cavity in the middle of the uterus. The uterine wall is divided into three layers. The outermost layer is the serosa layer, which acts as a covering. There is thick muscle in the middle, which is very elastic, so the uterine cavity can be large or small, large enough to accommodate a fetus. The inner wall is a thin membrane called the endometrium. The endometrium undergoes cyclical changes directly under the influence of sex hormones secreted by the ovaries.

Before ovulation, the follicles mainly secrete estrogen during their 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 fertilization does not occur until the eve of menstruation, the endometrium becomes thinner, the glands collapse, and no longer secrete mucus.

Then the lining of the uterus is shed and menstruation begins. A woman lays about 400 eggs in her lifetime, and the endometrium is shed and regenerated 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.

Through the above introduction, we can see that the reference value of time is different for different menstruation. It is best to check the thickness of the endometrium through vaginal B-ultrasound within three days after the menstruation is over. It is also worth noting that abortion can cause the endometrium to become thinner and lead to infertility, so female friends must pay more attention to this.
