There is no scientific evidence to support the claim that a specific fetal heart rate (FHR) is indicative of a particular gender. It's a popular belief among many pregnant women and their family members that a high fetal heartbeat rate points to having a male baby， while a low one indicates a female. While it may seem like a fun old wives' tale to rely on， it is not reliable or trustworthy when it comes to determining the gender of the baby.
The normal FHR ranges between 120 and 160 beats per minute (BPM) throughout pregnancy. However， there is no guarantee that the fetal heartbeat will remain steady throughout pregnancy. It can vary significantly from day today， even during labour. Factors such as the activity level of the baby， the presence of a fever， and medications may cause temporary fluctuation in the FHR.
Ultra sounds performed by competent healthcare practitioners between 18 to 22 weeks are the most reliable method to determine the sex of the baby. Because of this reliability， ultra scans remain the preferred method for determining a baby's gender before birth. In rare cases， the baby's position or amniotic fluid levels may not permit the ultrasound technician to view the baby's genitals.
In conclusion， fetal heart rate is not a reliable way to determine the gender of your unborn baby. You should speak with your healthcare provider if you have any concerns about the likelihood of your unborn baby's gender. Moreover， as many popular beliefs about pregnancy are not factual， it is essential to consult a trusted healthcare worker during your pregnancy for information and advice.
