What are the main reasons for spontaneous abortion

Chromosomal abnormalities, spontaneous abortion of the fetus after chromosomal examination, will usually find the existence of karyotype abnormalities, but also accompanied by fetal or placental structural abnormalities. The fourth is placental abnormality. Decidualitis may cause decidual hemorrhage or hyperplasia, which will lead to the dissolution of villous epithelial cells and decidual cells, and vascular obstruction in villi, which will affect the absorption and transportation of nutrients, leading to the separation of pregnant eggs, bleeding or abortion.

It's a blood type mismatch. Due to pregnancy or blood transfusion, Rh factor and ABO blood group factor will produce antibodies in the mother. During pregnancy, these antibodies will have placenta into the body of the fetus, which will lead to red blood cell agglutination and hemolysis, which will cause abortion.

Abnormal pregnant eggs, due to the defects of eggs or sperm, or both, or in early pregnancy, the mother is lack of folic acid, vitamins, hyaluronidase and other important substances, will hinder the normal development of pregnant eggs, which will lead to abortion.
