If the endometrium is as thick as fifteen millimeters, there is no need to solve it, because the endometrium will undergo different changes in different stages. When the endometrium thickens to fifteen millimeters, it will fall off naturally, and menstruation will occur at this time, which is when menstruation comes. 1. The thickness of the endometrium is different at different stages of the menstrual cycle. It is recommended to do a vaginal B-ultrasound three days after the end of menstruation to understand the specific thickness of the endometrium. If the endometrium is thick, menstruation is likely to be very painful and the fertilized egg will have difficulty implanting! It means that the endometrium is thicker than normal. The thickness of the endometrium cannot determine whether you can get pregnant. Whether ovulation occurs is the key to whether you can get pregnant. The normal range is 0.2-1.0 cm. 2. Proliferative stage: Around the 5th to 9th day of the menstrual cycle, the endometrium is very thin, the glands are sparse, the glandular ducts are narrow and straight, and the glandular cavity surface is flat. 3. From the 10th to the 14th day of the menstrual cycle, the endometrium becomes thicker and wavy, the glands and stroma proliferate significantly, and the number of glands begins to increase. 4. Secretory phase: From the 15th to the 19th day of menstruation, which is 1 to 5 days after ovulation, the endometrium continues to thicken and the glands further increase in size and curvature. 5. Around the 20th to 24th day of the menstrual cycle, which is 6 to 10 days after ovulation, the endometrium shows a high degree of secretory activity, and the curvature and expansion of the glands reach a peak. 6. In the late secretory phase, the thickness of the endometrium is about 5 to 6 mm. 7. Premenstrual period: approximately from the 25th to the 28th day of the menstrual cycle, which is 11 to 14 days after ovulation, which is equivalent to the regression period of the corpus luteum. The glands and glandular epithelial cells begin to shrink, degenerate, and secretions dry up, showing a phenomenon of exhaustion, and the thickness of the endometrium decreases by 1/5 to 1/3. 4 to 24 hours before the onset of menstruation, local spasmodic contraction occurs in the intimal spiral arterioles, causing ischemia and necrosis of the intima distal to the spasm. The permeability of the blood vessel wall increases, followed by vasodilation, and blood flows out of the broken blood vessels. |
