There are many ways to identify whether a pregnant woman is having a boy during pregnancy. Some identification methods do have some scientific basis, while others are purely folklore. You can use it as a reference. Many people also want to know whether fetal heart rate and fetal movement are related to the gender of the fetus. In fact, these have little relationship.
Can you tell whether the fetus is a boy or a girl by looking at the umbilical cord?
The umbilical cord cannot accurately determine the gender of the fetus. If the umbilical cord is too long or too short, pay attention to monitoring fetal movements and seek medical attention promptly if there are any abnormalities. The gender of the fetus is determined at the moment of fertilization. Both boys and girls are treasures. As long as the children are healthy, it is the greatest happiness for the family. Don\’t worry too much about whether it\’s a boy or a girl. You should go to the hospital regularly for prenatal check-ups, and adopt reasonable delivery methods according to the specific circumstances. 
Can B-ultrasound reveal umbilical cord torsion?
1. Umbilical cord torsion is a disease that can be discovered during obstetric fetal examination. The diagnosis is mainly made through obstetric B-ultrasound examination.
2. During the review, you can see a U-shaped or W-shaped image of the umbilical cord surrounding the fetal neck. On the color ultrasound, the umbilical cord blood flow can be seen in red and blue in the image, which clearly shows that the umbilical cord is entangled.
3. Therefore, using ultrasound to check whether the fetus has umbilical cord torsion is a good technical method that can help us further understand the condition.
Is umbilical cord torsion related to the immune system?
The cause of umbilical cord torsion is not entirely clear, but it may be related to abnormal development of the umbilical cord. Twist comes in many forms. It is possible that the umbilical artery and umbilical vein are twisted together in parallel, or that the umbilical artery is twisted around the umbilical vein, or that the umbilical artery and umbilical vein are twisted in a spiral.
Regardless of the cause, umbilical cord torsion requires close monitoring, fetal heart rate monitoring, and biophysical stage scoring if necessary. Because excessive torsion of the umbilical cord is associated with adverse fetal outcomes, that is to say, the umbilical cord is the channel that provides oxygen and nutrients to the fetus. Excessive twisting may affect the supply of oxygen and nutrients. If oxygen and nutrients are interrupted or reduced, intrauterine hypoxia may result. Therefore, if the B-ultrasound examination shows excessive torsion of the umbilical cord, fetal movements must be carefully counted. If you feel that fetal movement is reduced, you must go to the hospital in time.
By reviewing the above answers, we can find that umbilical cord torsion is not directly related to the immune system. If a pregnant woman is found to have umbilical cord torsion during prenatal check-up, she should remain calm and observe and treat according to the doctor\’s recommendations. At the same time, we should also pay attention to maintaining good living habits and emotional state to create a good environment for the healthy growth of the fetus.
