Spontaneous abortion 2 times, what reason is this?

Genetic abnormality is the most common cause of spontaneous abortion. 50% - 60% of the patients have chromosome abnormality in early abortion. Chromosomal abnormalities can be divided into numerical and structural abnormalities. The abnormal chromosome numbers were polyploid, trisomy and monosomy; Structural abnormalities include chromosome breakage, deletion and translocation. Most embryos with chromosomal abnormalities will have abortion. The causes of chromosomal abnormalities are inherited from parents and influenced by acquired environmental factors. Women after miscarriage should have a chromosome test with their husband to see if there is a problem. If there is any problem in the examination, it is advisable to consult the relevant doctor about the possibility of re pregnancy and related matters.

The environmental factors that can cause spontaneous abortion are physical, chemical and biological. Such as radioactive substances, heavy metals, DDT, pesticides and TORCH infection (rubella virus, herpesvirus, cytomegalovirus and Toxoplasma gondii, etc.). If there is adverse environmental contact before and after pregnancy, it may cause spontaneous abortion.

Maternal factors pregnant women suffering from certain diseases, such as acute infectious diseases can cause fetal death, abortion; Luteal insufficiency, hypothyroidism or hyperthyroidism, diabetes can affect decidua, placenta, fetal development and abortion. If it is this kind of factor, we should actively treat the primary disease, or use drugs during pregnancy to control the condition and make it stable, so as to achieve the purpose of preventing abortion.

Blood group antibodies, anticardiolipin antibodies, anti ovarian antibodies, anti endometrial antibodies, anti sperm antibodies, etc. If there are such immune factors, we should treat them according to the causes. After the elimination of immune factors, pregnancy again.
