Women all hope to have healthy and intelligent babies smoothly, but many women encounter the sad thing of miscarriage during pregnancy. Do you know what causes miscarriage? The following is a detailed introduction by the editor. Couples must pay attention to it.
1. Blood group incompatibility
Due to previous pregnancies or blood transfusions, antibodies against Rh factors and incompatible ABO blood group factors were produced in the mother. This pregnancy resulted in hemolysis caused by the placenta entering the fetal body and agglutinating red blood cells, leading to miscarriage.
2. Endocrine disorder
Excessive estrogen and insufficient progesterone are also causes of early abortion. Due to the period of placental formation replacing the luteal function of pregnancy during the 12th to 14th week of pregnancy, endocrine disorders, especially luteal insufficiency, are prone to occur.
3. Psychoneural factors
Such as shock and severe mental stimulation can also lead to miscarriage. In recent years, research has shown that noise and vibration have a certain impact on human reproduction.
4. Chromosome abnormality
Chromosome abnormalities include chromosome number abnormalities, such as monosomic, trisomic, polyploid, and structural abnormalities, such as breakage, deletion, and translocation, which can lead to miscarriage.
5. Placental abnormalities and placental endocrine insufficiency
"During early pregnancy, deciduitis can cause bleeding or hyperplasia of the decidua basalis, dissolution of villous epithelial cells and decidual cells, obstruction of blood vessels in the villi, and affect the absorption and delivery of nutrients, leading to separation, bleeding, and miscarriage of the pregnant egg from its attachment.".
6. Diseases of reproductive organs
Uterine abnormalities, such as bicornular uterus and uterine septum, are often the cause of miscarriage. However, uterine dysplasia is often the cause of infertility.
The reasons mentioned above can seriously affect women's pregnancy. Therefore, when couples are having children, they must pay attention to comprehensive sexual reproductive health checks, which can more effectively prevent these things that may harm the health of the fetus and ensure the smooth birth of the baby.
