Endometrial thickness refers to the thickness of the lining of the uterus, also known as the endometrium. This lining is shed during menstruation, and then rebuilds itself in preparation for a possible pregnancy.
The measurement of endometrial thickness is typically done using an ultrasound, and is important in determining a woman’s fertility and reproductive health. Here are some key things to know about endometrial thickness:
Normal endometrial thickness: The normal thickness of the endometrium varies throughout the menstrual cycle, and can range from 1 to 16 mm. In the early part of the cycle, the endometrium is thin, but it thickens in response to the hormone estrogen as ovulation approaches. After ovulation, the endometrium continues to thicken in preparation for implantation of a fertilized egg.
Abnormal endometrial thickness: Endometrial thickness that is outside the normal range can be a sign of various conditions, such as polyps, fibroids, endometrial hyperplasia, or cancer. In general, an endometrial thickness of less than 8 mm is considered thin, while a thickness greater than 16 mm is considered thick. However, the interpretation of endometrial thickness should always be done in conjunction with other clinical factors.
Diagnostic uses: Measuring endometrial thickness can be useful in diagnosing infertility, as a thin endometrium may not be able to support implantation of an embryo. It can also be used to detect abnormalities such as endometrial hyperplasia or cancer.
Treatment implications: If a woman has an abnormally thick endometrium, treatment may be necessary depending on the underlying cause. For example, if the thickness is due to endometrial hyperplasia, treatment may include medication to regulate hormone levels or surgery to remove the abnormal tissue. If the thickness is due to cancer, treatment will typically involve surgery, chemotherapy, or radiation.
In summary, endometrial thickness is an important factor in a woman’s reproductive health and fertility. Measuring endometrial thickness can help diagnose various conditions, and guide treatment decisions when necessary.
