They need to be checked one by one. Before pregnancy, intervention can prevent 11 weeks of pregnancy miscarriage!

1.孕卵异常。因精子和卵子有着某种缺陷，导致使胚胎发育到一定程度而终止妊娠。

1. Pregnant eggs are abnormal. Because sperm and eggs have some kind of defect, the embryo develops to a certain extent and terminates the pregnancy.

2.免疫因素。抗胚胎抗体阳性(大于1：64)。由于经期性生活、人流或分娩时，夫源组织通过开放的子宫内膜静脉进入母体，母体产生了特异性抗胚胎抗体，再次妊娠时，抗胚胎抗体与胎盘表层的Fibronectin 网发生体液免疫反应，Fibronectin遭到破坏后，胎儿绒毛组织暴露于母血中，细胞免疫发生，胚胎停育，继而发生自然流产。

2. Immunological factors. Antiembryonic antibody positive(greater than 1:64). Due to menstrual sex, miscarriage, or childbirth, the husband's source tissue enters the mother through an open endometrial vein, and the mother produces specific anti-embryo antibodies. When pregnant again, anti-embryo antibodies and the Fibonectin network on the surface of the placenta undergo a humoral response. After the destruction, The fetal villous tissue is exposed to the mother's blood, cell immunity occurs, the embryo stops breeding, and then spontaneous miscarriage occurs.

3.激素异常。当孕妇体内孕激素分泌不足时，使子宫蜕膜发育不良，影响受精卵的发育，从而容易引起流产。

3. Hormones abnormal. When the pregnant woman's body progesterone secretion is insufficient, causes the uterus molting membrane to develop poorly, affects the development of the fertilized egg, thus easily causes the miscarriage.

4.子宫形态因素。如子宫畸形、子宫肌瘤，腺肌症，内膜息肉，影响胎儿的生长发育而导致流产。

4. Uterine morphological factors. Such as uterine malformation, uterine myoma, adenomyosis, endometrial polyps, affecting the growth of the fetus and leading to miscarriage.

5.外因作用。如腹部受到外力的撞击、挤压，情绪受到重大刺激，情绪起伏大等，诱发子宫收缩引起流产。

5. External effects. For example, the abdomen is hit and squeezed by external forces, the mood is greatly stimulated, and the mood is undulating, causing uterine contractions to cause miscarriage.
