Patient's question:

Doctor's answer:

The thickness of the normal endometrium varies between 5-10 mm. The thickness of the endometrium also differs in different periods:
1. In the proliferative phase, the endometrium is about 9-10 mm thick.
2. In the secretory phase, the thickness of the endometrium is approximately 5-6 mm.
3. During the menstrual phase, the thickness of the endometrium can reach 8-10 mm.
The thickness of the endometrium fluctuates with the cyclical changes of the ovary. Starting from the 5th day of the menstrual cycle, the endometrium is in the proliferative phase, continuously thickening until the 14th day, when it can reach 3-4 mm. In the second half of the menstrual cycle, the endometrium is in the secretory phase.
