陈凤林教授指出:怀孕一个月流产的病因多与以下因素有关,需一一排查,孕前可干预!Professor Chen Fenglin pointed out that the causes of abortion in one month of pregnancy are mostly related to the following factors, which need to be investigated one by one and can be intervened before pregnancy.

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. Abnormal pregnant eggs. Pregnancy is terminated because of a defect in sperm and eggs, which results in the development of embryos to a certain extent.

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. Immune factors. Anti-embryonic antibody was positive (greater than 1:64). During menstrual sexual life, abortion or childbirth, husband-derived tissues enter the maternal body through open endometrial veins, and the maternal body produces specific anti-embryonic antibodies. During the second pregnancy, the anti-embryonic antibodies react with the Fibronectin network on the surface of the placenta. After the destruction of Fibronectin, the fetal villi tissue is exposed to maternal blood, cellular immunity occurs, and the embryo ceases to reproduce. And spontaneous abortion 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. Hormone abnormality. When the progesterone secretion in pregnant women is insufficient, the uterine decidua develops poorly, affecting the development of fertilized eggs, which easily leads to abortion.

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. Morphological factors of uterus. Such as uterine malformations, uterine fibroids, adenomyosis, endometrial polyps, affect the growth and development of the fetus and lead to abortion.

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 factors. For example, the abdomen is impacted and squeezed by external forces, emotions are greatly stimulated, emotional fluctuations, etc., which induce uterine contraction and cause abortion.

生化妊娠:指发生在妊娠5周内的早期流产,血中可以检测到HCG升高,大于25mlU/mL或者尿妊娠试验阳性,但超声检查看不到孕囊,提示受精卵着床失败,又被称为“亚临床流产”。

Biochemical pregnancy: refers to early abortion occurring within 5 weeks of pregnancy. The increase of HCG can be detected in blood, which is more than 25 mlU/mL or positive in urine pregnancy test. But no gestational sac can be seen by ultrasound examination, suggesting failure of fertilized eggs implantation, also known as "subclinical abortion".
