What is the normal thickness of the endometrium?

The thickness of the endometrium will actually affect women's fertility. If the uterus is thin, it is difficult to preserve the fetus and miscarriage is more likely to occur. The normal thickness of the endometrium is around 0.2 to 1 centimeter.

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. The thickness of the endometrium changes cyclically

Proliferative phase: During the ovarian cycle, when the follicles in the ovaries develop and mature, the endometrium proliferates under the action of estrogen secreted by the ovaries, which is called proliferative endometrium.

3. Secretory phase: After ovulation, the corpus luteum of the ovary secretes progesterone and estrogen, causing the proliferating endometrium to secrete, which is the secretory phase endometrium.

4. Menstrual period: After the corpus luteum in the ovary degenerates, due to the decrease in the amount of estrogen and progesterone, the endometrium loses its support and becomes necrotic and flaky, which manifests as menstruation. This period is called the menstrual endometrium.
