They continue to increase until they peak around week 9 , between and bpm for boys and girls alike. How nature chooses boy or girl The Chinese Calendar: When is sex determined? Then, I underwent a LOT of fetal heart monitoring, including one week of almost constant monitoring while hospitalized for preterm labor, as well as twice-weekly non-stress tests in which both babies heart rates were tracked for 30 minutes. What does heart rate measure?
The Aloka Alpha 10 machine was equipped with 3. They found that during the first trimester, male fetuses had a slightly higher average FHR when compared to female fetuses We calculated that it would require a sample size of over 12 participants to detect a significant difference in FHR and this led us to believe that there would be no statistically significant difference between the FHR of female and male fetuses. Sometimes the boy's heart rate was higher, sometimes the girl's heart rate was higher. So why not have a little fun just to break the monotony and see if you can both take a punt of whether you are having a boy or a girl? Two Medical Studies Disprove Fetal Heart Rate for Gender Prediction In the s, a senior sonographer analyzed thousands of births to determine whether fetal heart rate could predict a baby's sex.

The study was stopped because there was a very small absolute difference between the sexes 0. Though many women swear heart rate clued them in, the overall results are mixed at best.

Results We found no significant differences between What was found instead was that there is a change in baby heart rate according to their gestational age. The accuracy of US before 14 weeks gestation in identifying the sex of the fetus is poor [ 1 ]. Of these pregnancies, were revealed to be girls, while were revealed to be boys. Continuous variables were compared using Student's t-tests while categorical variables were compared using Chi-square test. Methods This was a retrospective review of medical records and ultrasounds performed between 8 and 13 weeks of gestation. In , another study published in Fetal Diagnosis and Therapy, tells us that analysis of over births proves again that fetal heart rate cannot predict whether a baby is a boy or a girl. If the heart rate is below BPM then the chances are that the baby will be a boy. And interestingly, this is what happened when they were looking for a correlation between foetal heart rate and gender. We planned to have an over enrollment to provide adequate numbers for each gender since the delivery rate for females is slightly lower at
