Can you tell the sex of a baby by its heartbeat?

Answer 1

No.

As the old wives' tale has it, if your unborn baby's heart rate is higher, above 140 beats per minute, that means you're carrying a girl. A lower heart rate below 140 bpm means you're having a boy. It's hard to resist such an easy test, and ever so tempting to over-analyze the pitter patter of that tiny heart. In early pregnancy, the reassuring sound of that heartbeat is just about the only thing we've got to show a baby's even there. But don't get your hopes up, or have your hopes dashed, based on your baby's heart rate, because it has absolutely nothing to do with what your baby has between its legs. This particular old wives' tale was found to be completely false by a medical study 20 years ago. Another medical study in 2006 confirms that fetal heart rate has nothing to do with the baby's sex. Here is more about it.
