No， the fetal heart rate (FHR) cannot determine the gender of the baby. While there are many old wives' tales and myths around fetal heart rate and gender prediction， there is no medical evidence to support them.
The FHR refers to the number of times the baby's heart beats per minute， which can be detected via ultrasound or a fetal heart monitor. The normal range is between 120 and 160 beats per minute， but it can fluctuate based on various factors like fetal activity， maternal heart rate， and maternal position. A higher FHR， like 170， may indicate that the baby is in an active phase or responding to external stimuli， but it doesn't reveal anything about the baby's gender.
Determining the sex of the baby requires a different approach， either through genetic testing， ultrasound， or amniocentesis. Most commonly， ultrasound is used to look at the baby's genitals between 18 and 20 weeks of pregnancy. However， it is important to note that even ultrasounds are not 100% accurate， as the position of the baby or other variables can obscure the view or lead to misinterpretation.
Therefore， it is best not to rely on FHR or any other unsubstantiated methods for gender prediction， and instead wait for medical confirmation through proper testing methods.
