what is the gender of my baby based on heart rate

The belief states that a heartbeat over 140 beats per minute (bpm) means you’re having a girl, while under 140 bpm indicates you’re having a boy. One that seems based on science is the belief that baby girls have faster heart rates than baby boys. So many old wives’ tales center on predicting a baby’s gender. Baby’s heart rate during pregnancy indicates its sex. That’s why we rounded up 17 popular beliefs about new motherhood and did some digging to find which ones are actually true and which aren’t.

While pregnancy and breastfeeding old wives’ tales are fun to talk about, they are not always based on fact. We’ve all heard some of the folklore surrounding pregnancy, birth and breastfeeding-like carrying your baby high means it’s a boy (this one is a myth!). The average female FHR was 151.7 +/- 22.7 bpm and male FHR was154.9 +/- 22.8 bpm (p = 0.13).Ĭontrary to beliefs commonly held by many pregnant women and their families, there are no significant differences between male and female FHR during the first trimester.What pregnancy and breastfeeding myths should you believe? We’re separating fact from fiction. There were no statistical differences in mean maternal age, gravidity, parity, and mean gestational age at the time of the first study (9.0 +/- 2.3 weeks for female fetuses and 9.0 +/- 2.3 weeks for males, p = 0.7). Of these, 244 (51%) were female and 233 (49%) were males. Of the 966 first-trimester studies performed, 477 met the inclusion criteria.

Sonographically assigned fetal gender was confirmed at delivery. Multiple gestations, miscarriages and pregnancies with uncertain fetal gender were excluded. All subjects underwent second-trimester sonography at 18.0-24.0 weeks' gestation by the same team, and fetal gender was recorded. The sonographic studies were performed by a single sonographer and reviewed by the first author. Indications for the sonographic study included first-trimester bleeding, uncertain gestational dating, poor obstetrical history, and aneuploidy screening by nuchal translucency. Our goal was to determine whether fetal heart rate (FHR) of males and females during the first trimester is significantly different.įrom November 1997 to February 2003 we enrolled pregnant women with singleton gestations who underwent obstetric sonography at less than 14 weeks of gestational age. Many expecting parents wish to ascertain fetal gender early in pregnancy.
