The causes of fetal arrest during pregnancy usually include chromosomal abnormalities, endocrine factors, environmental factors and so on.
1. Chromosomal abnormality: usually when either parent has chromosomal abnormality, it may lead to fetal arrest during pregnancy. If the pregnant woman is older than 35 years old, it may also affect the chromosome segregation process, leading to chromosome abnormality and fetal arrest during pregnancy.
2. Endocrine factors: Diseases such as polycystic ovary syndrome, luteal insufficiency and abnormal placental function may also lead to fetal arrest during pregnancy.
3. Environmental factors: If the pregnant woman is exposed to radioactive substances and toxic chemicals during pregnancy, it may also lead to fetal arrest during pregnancy.
Patients need to go to the hospital for regular checkups after pregnancy. In case of fetal arrest, it is recommended to remove the embryo in time to avoid infection in the uterine cavity.
