Fetal heart rate of 150 cannot tell whether the fetus is a boy or a girl, and fetal heart rate has nothing to do with the sex of the fetus.
Normal fetal heart rate is 110-160 beats per minute, the fetal heart rate can reflect the condition of the fetus in the uterus, through the fetal movement, fetal heart condition, can be inferred whether there is intrauterine hypoxia in the fetus. However, fetal heart rate has nothing to do with gender, whether it is a boy or a girl, there is no difference in fetal heart.
Fetal heart rate is also not fixed, when measuring the fetal heart, if the fetus is in the sleeping period, the fetal heart rate will be slightly slower, if the fetus is in the active period, the fetal heart rate will also be slightly faster.
It is not scientific to estimate the sex of a fetus by its heart rate. There is no need for pregnant women to be overly concerned about the sex of the fetus, as long as the baby is normal, there is no need to worry. During pregnancy, pregnant women should pay attention to balanced nutrition, rest, appropriate activities, and go to regular hospitals for regular checkups.
