male fetus' heart rate can vary depending on gestational age and individual factors. Generally speaking， the normal fetal heart rate range is between 110 and 160 beats per minute. However， some studies have suggested that male fetuses may have slightly higher heart rates compared to female fetuses.
One study published in the Journal of Obstetrics and Gynaecology Research found that male fetuses had a mean heart rate of 148.7 beats per minute， whereas female fetuses had a mean heart rate of 144.4 beats per minute. Another study published in the Journal of Ultrasound in Medicine found that male fetuses had a mean heart rate of 150.2 beats per minute， whereas female fetuses had a mean heart rate of 147.2 beats per minute.
It's important to note that these slight differences in heart rate between male and female fetuses are not clinically significant and do not predict the sex of a fetus. Moreover， a fetal heart rate that falls outside the normal range doesn't necessarily indicate a problem. Other factors， such as abnormalities in the fetal heart， maternal illness， or medication use， can result in a higher or lower fetal heart rate.
If you're concerned about your baby's heart rate or have any other questions about your pregnancy， it's important to talk to your healthcare provider. They can provide you with individualized information about your pregnancy and help address any concerns you may have.
