Fetal arrest after pregnancy may be caused by chromosomal abnormalities, endocrine factors, environmental factors, infectious factors and so on.
1. Chromosomal abnormality: when either parent has chromosomal abnormality, it may cause fetal arrest. In addition, maternal age greater than 35 years old may affect the process of chromosome separation, resulting in chromosomal abnormalities and the occurrence of fetal arrest.
2. Endocrine factors: such as polycystic ovary syndrome, luteal insufficiency, abnormal placental function, hyperprolactinemia, hyperthyroidism, gestational diabetes mellitus and other diseases, may lead to the phenomenon of fetal arrest after pregnancy.
3. Environmental factors: If the pregnancy is exposed to radioactive substances, toxic chemical agents, microwaves, noise overstimulation, etc., it may cause lead to embryonic arrest.
4. Infectious factors: mainly refers to the inflammation that occurs in the uterus and neighboring tissues and organs, such as mycoplasma or chlamydia infection, it will easily cause endometritis, and there is the occurrence of post-pregnancy fetal arrest.
Pregnant women usually need to go to the hospital for regular checkups after pregnancy, and if the phenomenon of fetal arrest occurs, it is necessary to remove the embryo in time to prevent the infection of the uterine cavity.
