If a woman intends to have a baby, it is recommended to keep the fetus for the time being, but she should pay attention to regular obstetric examinations during pregnancy, including 4D ultrasound, Down’s syndrome screening and other related screening tests. If the development of the fetus is normal, no special treatment is needed. If the fetus has developmental abnormalities, it is recommended to terminate the pregnancy in order to achieve eugenics.
