A normal endometrial thickness is generally considered to be less than 14 mm at any point in a woman's menstrual cycle.
Understanding Endometrial Thickness
The endometrium is the inner lining of the uterus, and its thickness changes throughout the menstrual cycle. This fluctuation is primarily influenced by hormones.
Normal Thickness Ranges
| Menstrual Phase | Endometrial Thickness (mm) |
|---|---|
| Menstruation | 2-4 |
| Other Cycle Stages | Less than 14 |
During menstruation, the endometrial lining sheds, resulting in a thinner lining, which typically measures between 2 and 4 millimeters in pre-menopausal women. However, a healthy endometrium during other phases of the cycle will generally be less than 14 mm.
Why is Endometrial Thickness Important?
- Pregnancy: A healthy endometrium is essential for a successful pregnancy. The fertilized egg implants into the lining of the uterus; therefore, optimal thickness is needed.
- Menstrual Cycle: Changes in endometrial thickness are part of the normal menstrual cycle. Monitoring the thickness can be useful in assessing menstrual health.
Considerations
- Variations: While the thickness should generally be less than 14mm, some natural variations do exist, and it’s important to discuss any concerns with a healthcare provider.
- Individual Health: Other health conditions might affect endometrial thickness. It's important to note that medical advice should be sought when questions or concerns exist regarding individual health.
