Nowadays, when people hear “fetal sterilization” is like talking about a tiger, very panic. The main causes of fetal sterilization are as follows: Western medicine analysis: From the perspective of Western medicine, there are several causes of embryonic sterilization: 1, reproductive endocrine aspects: because the early development of the embryo needs three important hormone levels, namely estrogen, progesterone, chorionic gonadotropin, if the mother’s own endogenous hormones are not enough to meet the needs of the embryo, it will cause embryonic sterilization; 2, immune factors: if you have some kind of antibodies, you will not be able to meet the needs of the embryo. If the mother’s own endogenous hormones are not enough to meet the needs of the embryo, it will cause the embryo to stop; 2. Immunological factors: if one has some kind of antibodies, it will resist the development of the embryo; 3. Reproductive tract infection: after the mother’s infection, the pathogen can exercise the placental infection through the blood, causing damage to the chorionic membrane and capillary endothelium, and destroying the placental barrier, and the pathogen will enter the fetus, leading to miscarriage, embryonic arrest and fetal malformation. In recent years, many studies have shown that mycoplasma infection is associated with embryonic arrest, and the rate of positive cervical secretion mycoplasma infection in women with arrested embryos is significantly higher than in normal women, with highly significant differences; 4. Problems of the uterus: the internal environment in the uterus and the overall environment of the uterus may have an impact on the embryo, the internal environment is the endometrium, if too thin, too thick will affect the implantation. Or the uterus is deformed and will not develop; 5. chromosomal problems; 6. environmental factors: such as the mother received harmful substances, received radiation or a lot of electromagnetic radiation, took some drugs, smoking or alcohol, infected with viruses or suffering from certain chronic diseases. The Chinese medicine analysis: Although the occurrence of fetal abortion is related to a variety of causes, but the main blame on the mother, Chinese medicine believes that the human body is an organic whole, the formation and development of the fetus, not only the need for kidney consolidation, but also inseparable from the blood to feed, if the subsidy to the expectant mother, so that the qi and blood strong and vigorous, consolidation of the normal mother strong since the sprouting of children. If the kidney essence is not enough to transform the blood, or the qi and blood are not enough, the twins are not fed, and the fetus is not nurtured. “The kidneys carry the fetus, the kidneys store the essence, the essence is transformed into gas, the essence is sufficient for the gas, the gas is strong, the fetus is strong; the essence is transformed into blood, that is, the fetus can sprout, and can moisten the fetus, so that the twins develop normally. The kidneys are the foundation of the innate, and the spleen is the foundation of the postnatal, the postnatal feeds the innate, so the deficiency of kidneys and spleen causes the environment for fetal growth to be affected, resulting in fetal arrest, fetal atrophy or slippery fetus, falling fetus.
