Heart rate vs gender

[kat.]

Been told the theory of telling gender from heart rate, we have stayed team yellow but still wondering if anyone has found this to be true..
140bpm or less boy or more for a girl iv been told ?

We had a girl and hb was always around 135-140

My mw correctly said girl when she heard my baby's heartbeat on the Doppler.. Not sure what it was though lol but it sounded like a train x

I'm having a girl, when I heard the heartbeat at 18w it was 146

It was true with my first two.

this one I haven't had a doppler, the MW has estimated 140 resting heart rate with the pinard and 150 when s/he was active. But I don't know what I'm having and it's right on the cusp lol.

I'm having a boy and his heart beat is always around 150-160 x

I'm having a baby girl & HB was 150. The sonographer however said this theory along with the skull theory is in his opinion an old wives tale. 🤔
