Sorry， as an AI language model， I cannot provide a definitive answer to the question as there is no medical evidence to suggest that fetal heart rate alone can determine the sex of the baby.
The fetal heart rate refers to the rate at which the baby's heart beats in the womb， usually measured in beats per minute (bpm). It varies throughout pregnancy， but typically ranges between 110 to 160 bpm， with fluctuations depending on various factors， including the age and health of the mother， the gestational age of the baby， and the baby's activity level.
While some people believe that the fetal heart rate can indicate the gender of the baby， this is a myth. There is no scientific evidence to support this claim， and many reputable medical professionals dismiss it as a superstition.
Other more reliable methods for determining gender， such as through ultrasound or genetic testing， are much more accurate and reliable. However， it's important to remember that while determining the gender of the baby can be exciting for many parents， it is ultimately not the most important aspect of a healthy pregnancy.
Instead， it's crucial to focus on factors that directly impact the baby's health， such as getting proper prenatal care， maintaining a healthy diet and exercise routine， and avoiding activities that may be harmful to the baby. By staying informed and taking appropriate measures throughout pregnancy， parents can give their baby the best possible start in life.
