The heart rate of a male fetus is the same as that of a female fetus, there is no difference, the normal fetal heart rate is 110~160 beats per minute. Fetal heart is the sound of fetal heartbeat in the uterus, by listening to the fetal heart sound can understand whether the fetus is normal or not. Generally the fetal heart rate is related to the physical fitness of the pregnant woman, the normal development of the fetus, the uterus, the state of the placenta and so on, and has nothing to do with the boy or girl. If the measured fetal heart rate is much higher than the normal range, it may be caused by fetal hypoxia; if the fetal heart rate is lower, it may be caused by severe hypoxia or abnormal development of the fetus, etc. If a pregnant woman finds that the fetal heart rate is significantly higher than the normal range, it may be caused by fetal hypoxia. If a pregnant woman finds that the fetal heart rate deviates significantly from the normal range, it is recommended that she consult a doctor in time, complete the relevant examinations under the doctor’s guidance, identify the cause of the disease and take appropriate treatment measures.
