What is the normal thickness of the uterus?

According to experts in related fields, there are many reasons for the thickening of the endometrium. The most likely reason is that during the ovarian cycle, when follicles develop and mature in the ovaries, the blood supply to the endometrium is enhanced under the action of estrogen secreted by the ovaries, resulting in thickening of the endometrium. The following is a summary of the relevant knowledge:

Generally, the thickness of normal endometrium ranges from 5 to 10 mm. The thickness of endometrium varies in different periods: 1. The thickness of endometrium in proliferative stage is about 9 to 10 mm. 2 During the secretory phase, the thickness of the endometrium is about 5 to 6 mm. 3 Menstrual period: The thickness of the endometrium can reach 8-10mm. The thickness of the endometrium changes with the cyclical changes of the ovaries. From the 5th day of the menstrual cycle, the endometrium is in the proliferative phase, and the endometrium continues to thicken until the 14th day of menstruation, and can thicken to 3-4mm; in the second half of the menstrual cycle, the endometrium is in the secretory phase, but it continues to thicken, and the endometrial thickness can reach 10mm before menstruation. Under normal circumstances, the thickness of a woman's endometrium is 8-12 mm, and the minimum cannot be less than 6 mm. Generally speaking, the thickness of the endometrium is about 10mm just after pregnancy. Experts point out that the thickness of the endometrium that is conducive to conception is about 8 mm. The best time for the endometrium to be fertile is during the luteal phase.

The main causes of endometrial thickening are:

1. Endogenous estrogen. (1) Anovulation (2) Obesity (3) Endocrine functional tumors

2. Exogenous estrogen. (1) Estrogen replacement therapy (2) Application of tamoxifen: Tamoxifen (TAM) has anti-estrogen effects and is therefore used in postmenopausal patients with advanced breast cancer.

According to relevant experts, "The thickness of the endometrium will change at different times in a woman's menstrual cycle, mainly due to the influence of hormone secretion at different periods. If the endometrium is thin due to factors such as miscarriage, it will have a great impact on women's pregnancy." Therefore, women must not take their health lightly, and must always remember to take care of their bodies!
