Does the thickness of the endometrium affect pregnancy?

Will the thickening of the endometrium affect pregnancy? In life, many female friends have the trouble of endometrial thickening. Why is this? The main reason is that the thickening of the endometrium will have a certain impact on women's fertility. Whether the endometrium is too thin or too thick, endometrial migration, it may cause abnormal fertility. Regarding the question of whether the thickening of the endometrium will affect pregnancy, let's take a look at the detailed introduction of authoritative experts:

1. Normal endometrial thickening

During the ovarian cycle, when follicles develop and mature in the ovaries, the blood supply to the endometrium is enhanced under the action of estrogen secreted by the ovaries, and a gradual thickening phenomenon, namely proliferative endometrium, occurs. The thickening of the endometrium provides good conditions for the implantation of the fertilized egg and the growth and development of the embryo.

After ovulation, the corpus luteum of the ovary secretes progesterone and estrogen, causing the thickened endometrium to secrete, which is the secretory phase endometrium. The proliferative phase begins on the fifth day of the menstrual cycle and lasts for 7 to 10 days. At this time, the estrogen level in the blood gradually increases. The endometrium begins to repair, the endometrium gradually thickens, and blood vessels and uterine glands also grow accordingly, but the endometrium is still very thin at this time;

Secretory phase: It starts from the 15th day after the menstrual period and lasts for about 14 days. At this time, the ovarian follicle has ovulated, and the corpus luteum is formed after ovulation. The progesterone secreted makes the thickened endometrium continue to thicken, the gland further enlarges and bends, and secretes mucus. At this time, the endometrium becomes thick and soft, reserves the necessary secretions, and is ready to be implanted by the fertilized egg at any time.

2. Abnormal endometrial thickening

If the ovarian hormones are disordered, it is easy to cause abnormal thickening of the endometrium, that is, endometrial hyperplasia, which is caused by a large amount of estrogen stimulating the endometrium. The clinical manifestations are irregular and excessive abnormal uterine bleeding. Patients may have continuous bleeding after a long period of amenorrhea, which may be suspected of miscarriage clinically. It may also be manifested as shortened cycles and prolonged menstruation, and the bleeding time can be up to 1 month. Therefore, abnormal thickening of the endometrium will affect pregnancy.
