What's the reason for the stillbirth

summary

My good friend was pregnant twice, and her baby stopped when she was less than 3 months old, which made her very painful. Now I'd like to share with you the reason why she always stopped.

What's the reason for the stillbirth

First, endocrine disorders: embryo implantation and continued development depend on the coordination of complex endocrine systems. Any link disorder can lead to abortion. During the early development of embryo, three important hormone levels are needed, one is estrogen, one is progesterone, and the other is human chorionic gonadotropin. As a mother, if her own endogenous hormone is insufficient, it can not meet the needs of the embryo, which may cause the embryo to stop breeding and abortion.

Second, immune factors: intrauterine embryo or fetus is allogeneic transplantation, because the fetus is the combination of parents' genetic material, and the mother can not be exactly the same. Maternal fetal immune maladjustment causes maternal rejection of the fetus. The common autoimmune diseases are systemic lupus erythematosus, scleroderma, mixed connective tissue disease and dermatomyositis. The second is the problem of reproductive immunity. If we carry certain antibodies, it may affect the development of embryos. In fact, the detection of antibodies varies from hospital to hospital, and doctors have different opinions. From our research point of view, we think that there are four influencing factors,

Third, the problem of chromosome: if the chromosome is abnormal, it will also lead to early abortion. Chromosome abnormalities include quantitative and structural abnormalities, which can be divided into aneuploid and polyploid. The most common abnormal karyotype is triploid, and trisomy 16 accounts for 1 / 3, which is often fatal. 25-67% of trisomy 21, 4-50% of trisomy 13 and 6-33% of trisomy 18 were inevitable abortion.

matters needing attention

There are many reasons leading to embryo arrest. As long as a woman has had a fetal arrest, it is recommended to have a detailed examination, such as chromosome, vaginal secretions, sex hormones, endometrial examination. Only after the cause is clear, can symptomatic treatment be carried out.
