What are the causes of spontaneous abortion? The causes of spontaneous abortion are different for any pregnant woman.

There are many reasons for spontaneous abortion, including genetic factors and chromosomal abnormalities, including chromosomal abnormalities of the couple and chromosomal abnormalities of the embryo. Common chromosomal abnormalities of the couple include balanced translocation and Robertsonian translocation. Endocrine disorders in the mother, manifested as corpus luteum insufficiency, polycystic ovary syndrome, hyperprolactinemia, thyroid disease and diabetes, may all be causes of spontaneous abortion.

For many families, having a baby of their own is something to look forward to. It is not that the main purpose of having a child is to carry on the family line. In many cases, having a child can bring a lot of joy to a family. However, some people are prone to spontaneous abortion. So, what are the causes of spontaneous abortion?
The reasons for miscarriage for any pregnant woman are different. It may be due to external factors or the pregnant woman's own reasons. It is recommended that pregnant women go to the hospital for examination to find out more.
Wrong lifestyle habits <br/>Many spontaneous miscarriages of pregnant women are related to their lifestyle habits. It may be caused by excessive radiation or excessive mental stress of the pregnant woman. There are many reasons.
Abnormal fertilized egg <br/>Due to defects in the egg or sperm, or both, or in the early stages of pregnancy, the mother's lack of some important substances such as folic acid, vitamins, hyaluronidase, etc., will hinder the normal development of the fertilized egg, which will cause miscarriage.
Blood type incompatibility <br/>Due to previous pregnancy or blood transfusion, Rh factor and ABO blood type factor will produce antibodies in the mother's body. During pregnancy, these antibodies will enter the fetus through the placenta, causing red blood cells to aggregate and produce hemolysis, which will cause miscarriage.
Chromosomal abnormality <br/>After a spontaneous abortion, the fetus is usually found to have abnormal karyotype after a chromosomal examination, and is also accompanied by structural abnormalities such as the fetus or placenta. Placental abnormalities and decidual inflammation may cause decidual bleeding or hyperplasia, which may lead to the dissolution of chorionic epithelial cells and decidual cells, and blockage of blood vessels in the villi, which will affect nutrient absorption and transportation, leading to bleeding or miscarriage of the fertilized egg separation.
The mother suffers from systemic diseases such as acute infectious diseases, chronic diseases, vitamin deficiency or chronic poisoning such as lead and alcohol. These factors can cause miscarriage. Diseases of the reproductive organs and uterine malformation are one of the causes of miscarriage. Uterine fibroids, especially submucosal fibroids, are likely to affect fetal development and cause miscarriage.
