How thick is the endometrium during menstruation?

When female friends have a physical examination, one of the items is to check the condition of the endometrium. The thickness of the endometrium will be marked in the physical examination report. After the doctor looks at it, he will also ask what stage the woman is in to understand whether the endometrium is normal. The endometrium is a very magical part. The endometrium is different in each period. Let’s talk about how thick the endometrium is during menstruation.

Generally speaking, menstruation will come when the normal thickness of the endometrium reaches 8-10mm.

At this time, the levels of estrogen and progesterone decrease, activating the synthesis of prostaglandins in the endometrium. Prostaglandins can stimulate the contraction of the uterine muscle layer and cause continuous spasm of the spiral arterioles in the functional layer of the endometrium, resulting in a decrease in endometrial blood flow. The area of ​​damaged, ischemic, and necrotic tissue gradually expands. Tissue degeneration and necrosis, increased permeability of the blood vessel wall, and rupture of the blood vessels lead to the formation of hematoma at the bottom of the intima, which promotes tissue necrosis and exfoliation. The degenerated and necrotic endometrium mixes with blood and is discharged to form menstrual blood.

In fact, when menstruation comes, the estrogen and progesterone in the body quickly withdraw after the thickening of the endometrium, and bleeding occurs. If you are sure that you are not pregnant, you can measure the hormone level in your body to find out the cause of the menstrual cycle disorder.

Does endometrial thickness affect pregnancy?

Does the thickness of the endometrium affect pregnancy? Many patients with endometrial thickness are very concerned about this issue. The endometrium is the mucous membrane covering the uterine cavity. It is one of the most differentiated tissues in the human body. The thickness of the normal endometrium changes with the menstrual cycle and is not constant.

The thickness of the endometrium affects pregnancy, just like crops cannot grow in barren land. If the thickness of the endometrium is not enough, it is like the land is not fertile enough and cannot provide sufficient conditions for the implantation and growth and development of the fertilized egg, thus affecting women's fertility.

So, what is the appropriate thickness of the endometrium required for pregnancy?

The thickness of a woman's endometrium changes with the menstrual cycle. Generally speaking, the normal endometrial thickness is between 5mm and 10mm. It is thickest during ovulation and falls off during menstruation, leaving only the basal layer.

Currently, most people believe that an endometrial thickness of 8-10mm is more suitable for conception.

Due to the different physical conditions of each woman, the standard of endometrial thickness is also different for each woman. Some women have a thin endometrium but can still successfully implant, while some women have difficulty implanting despite normal endometrium. This requires the doctor's experience to make a judgment, while also considering the possibility of other lesions.

There are many reasons for infertility, not only the problem of endometrial thickness, but also other factors such as ovarian factors, fallopian tube factors, cervical factors, etc., which require clear judgment before effective treatment.
