Endometrial thickness 7mm

The thickness of the uterine wall changes at different times in a woman's menstrual cycle, mainly due to the influence of growth hormone metabolism at different stages. If the thin endometrium is caused by factors such as miscarriage, it will have a great impact on women's pregnancy. So, is the endometrial thickness of 7mm normal?

Is 7mm thickness normal?

The normal thickness of the endometrium is 7mm. The normal thickness of the uterine wall is 5-10mm, but the thickness of the endometrium changes continuously with the menstrual cycle. The uterine wall will thicken before the menstrual period and soften after the menstrual period. The thickness of the uterine wall will reach 1-3mm within 6-14 days of the menstrual period. During the 15th to 28th day of the menstrual period, the endometrium is 5-7mm thick. A uterine wall that is too thin is not conducive to pregnancy, and a uterine wall that is too thick may cause disease. If you have other uncomfortable symptoms, it is recommended to go to the hospital for a gynecological color ultrasound.

The thickness of the uterine wall changes with the ovarian cycle and the menstrual cycle. For example, on the 6th day of the menstrual cycle, the endometrium is 5 to 6 mm. During the ovulation period in the middle and late menstrual period, the thickness of the endometrium should be between 8 and 10 mm. If it is less than 8mm, that is, 7mm, the endometrium may be too thin, making it difficult for the sperm and egg to combine and the embryo to implant. During the metabolic period, which is the second half of the menstrual cycle, the thickness of the endometrium can reach 10 to 12 mm.

Therefore, if it is 7mm in the middle and late stages of the menstrual period and you are worried about not getting pregnant, you can undergo endocrine regulation and, if necessary, a hysteroscopy can be performed to check whether there is adhesion in the uterine cavity or whether there is endometrial fibrosis.

There are many reasons why the uterine wall becomes soft, the most common reasons are:

1. Endocrine imbalance

Women's mentality has a great impact on the uterine wall. Long-term anxiety and worry often lead to endocrine imbalance, which in turn affects the thickness of the endometrium.

2. Abortion curettage causes damage to the endometrium.

The endometrium is divided into three layers. The top layer must be shed every month, while the inner and bottom layers do not shed. If the inner layer is damaged, the impact is not significant. If the bottom layer is damaged, the impact will be serious.

3. Endometrial degeneration

Such as uterine polyps, endometrial cancer, etc.

A thin endometrium can cause the sperm and egg to combine and fail to implant, leading to infertility.
