What is the cause of spontaneous abortion? It is best to check the cause first

The causes of spontaneous abortion are very complex, including fetal chromosomal abnormalities, maternal reproductive tract malformations, lesions, infections, endocrine diseases, immune abnormalities and other factors. In fact, the cause of spontaneous abortion in women is also related to men. When the quality of male sperm is poor, even if the woman is pregnant, she will have a miscarriage afterwards.

Women should be especially careful after pregnancy, otherwise it may lead to miscarriage. Spontaneous miscarriage is a common type of miscarriage. For healthy women, it will not affect their pregnancy, but for women with poor physical conditions, spontaneous miscarriage is very likely to occur. So, what are the causes of spontaneous miscarriage?
1. Chromosomal abnormalities <br/>Such as balanced heterotopia and Robert's heterotopia, although there is no abnormality in appearance, their children are very likely to have chromosomal abnormalities.
In addition, radiation, viruses, drugs and other factors may also cause chromosomal abnormalities. For these embryos, abortion plays a role of "survival of the fittest".
2. Abnormal sperm quality <br/>If a man is in a high temperature or radiation environment for a long time, or is addicted to alcohol or smoking, the sperm quality may be changed, leading to abnormal fertilized eggs and miscarriage.
3. Female illness <br/>Maternal factors including endocrine abnormalities, such as luteal insufficiency, polycystic ovary syndrome, diabetes, hypothyroidism and hyperthyroidism, obesity, etc., can also cause miscarriage after pregnancy.
Malformations or organic lesions of the female reproductive organs, such as uterine fibroids, uterine septum, uterine cavity adhesions, and relaxation of the internal cervical os, will increase the risk of miscarriage.
4. Immune dysfunction <br/>Abortion is closely related to immune factors and may be an important cause of recurrent miscarriage. After pregnancy, the fertilized egg must grow in the uterus, which is equivalent to allogeneic transplantation from an immune perspective. To put it in a more vivid way, there are certain antibodies in the uterus that can play a "sealing" role and protect the embryo well.
If this antibody is lacking, the uterus will think that the embryo is a "bad thing" and will mobilize the immune system to "attack" the embryo and expel it from the body as a foreign body.
If there has only been one spontaneous abortion, the couple should not worry, but should relax, exercise actively, and prepare for pregnancy after the menstruation returns to normal. If a woman has three or more spontaneous abortions during pregnancy, it is called recurrent abortion. For such couples, it is best to first check the cause and then carry out targeted treatment.
