A 6-month-old fetus is usually not viable after birth because 6 months of pregnancy is about 24 weeks of gestation, which is the middle of pregnancy, and the fetal organs are fully developed but immature, especially the fetus has very poor lung function and lack of alveolar surface active substances, and the alveoli cannot expand normally after birth, and normal breathing will not occur, and various substances in the body will be lacking, which will easily lead to intracranial hemorrhage in newborns This can lead to intracranial hemorrhage or other serious complications, such as necrotizing small bowel colitis and respiratory distress syndrome. In the case of a fetus in the sixth month of pregnancy, if for some reason it is aborted, it will not survive after delivery.
