Is 1.5cm endometrial thickness normal?

Is it normal for the endometrium to be 1.5cm thick? Women who are familiar with this aspect believe that such a thickness is abnormal for women and will seriously affect their success rate of conception. Therefore, for many women who want to get pregnant, if their endometrium is relatively thin, they can receive treatment as soon as possible to increase the probability of pregnancy.

It is normal for the endometrium to be around 1.5cm during ovulation, and it usually reaches around 1.2-1.5cm before menstruation. The most common cause of thick endometrium during puberty is that the ovaries do not ovulate. If menstruation does not come for a long time, the endometrium will thicken. Or, even if menstruation can come, the endometrium cannot be completely shed, which will also increase the thickness of the endometrium during menstruation and cause bleeding for a long time.

The thickness of normal endometrium changes with the menstrual cycle and is not constant. The endometrium is divided into the basal layer and the functional layer. The basal layer is not affected by the changes in ovarian hormones during the menstrual cycle and does not fall off during the menstrual period; the functional layer is affected by ovarian hormones and shows periodic changes, and becomes necrotic and falls off during the menstrual period.

Expert analysis: What are the causes of endometrial thickening?

Obesity: In obese women, androstenedione secreted by the adrenal glands is converted into estrone by aromatase in adipose tissue. The more adipose tissue there is, the stronger the conversion capacity and the higher the estrone level in the plasma, thus causing a persistent estrogenic effect.

Endocrine functional tumors: Endocrine functional tumors are rare tumors, but in research statistics, endocrine functional tumors account for 7.5%. The gonadotropin function of the pituitary gland is abnormal, and ovarian granulosa cell tumor is also a tumor that continuously secretes estrogen.

Anovulation: Anovulation may occur in adolescent girls, perimenopausal women, disorders in a certain link of the hypothalamus-pituitary-ovarian axis, polycystic ovary syndrome, etc., causing the endometrium to be continuously affected by estrogen for a longer period of time, without progesterone to counteract it, lacking the transformation of the cyclical secretory phase, and being in a state of hyperplasia for a long time.

Changes in the endometrium are related to many factors. I believe that through the above introduction, many women have a comprehensive understanding of this aspect. Therefore, many women with an endometrial thickness of 1.5 cm should pay attention to it, because such a thickness is abnormal. They should go to the hospital for a comprehensive examination to see what caused it.
