Umbilical cord torsion is not directly related to the immune system. If torsion of the umbilical cord is found, fetal movements need to be closely monitored and medical treatment is required if necessary. Gender does not affect the health of the fetus. Regardless of whether it is a boy or a girl, health is the most important thing. Regular prenatal check-ups and reasonable delivery. Maintain good living habits and create a good growth environment for the fetus.
