After fetal growth restriction occurs, it is still necessary to send the fetus for examination after dealing with any abnormalities that arise. There are many factors that can cause embryonic arrest, such as maternal factors, abnormal immune function, and the environment of the pregnant woman. More importantly, factors related to the embryo, such as chromosomal abnormalities in the embryo, are the main cause of embryonic arrest. Therefore, after embryonic arrest occurs, it is recommended to go to the hospital for a fetal chromosomal examination to lay a good foundation for the next conception.
