What is the normal thickness of the endometrium?

The endometrium is a layer of tissue inside the uterine wall that responds to both estrogen and progesterone. The thickness of the endometrium changes with estrogen levels, and the normal range is about 7 mm to 14 mm. The main function of the endometrium is to provide an environment for the fertilized egg to implant. Every month, the endometrium changes at different stages of the menstrual cycle to provide the fertilized egg with the right conditions for growth and development.

During the menstrual period, the thickness of the endometrium is 2-4 mm; during the proliferative phase, which is the 5th to 14th day of the menstrual cycle, the thickness of the endometrium increases from 0.5 mm to 3-5 mm. During ovulation, the endometrium continues to thicken to provide a suitable implantation environment for the fertilized egg. The thickness of the endometrium is usually around 8-12 mm. If fertilization is not achieved, the endometrium will gradually thin at the beginning of the luteal phase. Usually, the thickness of the endometrium during the luteal phase is around 6-10 mm. If the thickness of the endometrium is less than 2 mm or greater than 15 mm, there may be diseases such as endometrial hyperplasia, polyps, and fibroids. It is recommended to seek medical attention in time. The thickness of the endometrium of menopausal women should not exceed 5 mm, and the endometrium of older women who are about to enter menopause usually does not exceed 8 mm after the end of menstruation. If the thickness of the endometrium exceeds this range, medical examination is required.

The normal range of endometrial thickness may vary due to individual differences and other factors, and the method of measuring endometrial thickness may also have a certain impact on the results. If you feel uncomfortable, you need to see a doctor in time for relevant examinations.
