Old Wives’ Tales for New Mothers

A lot of old wives’ tales, particularly those concerning childbirth and gestation period, have been proven ineffective and/or false by advances in medicinal knowledge. An interesting example is the use of fetal heart rate monitor, also known as the Doppler, in order to predict the sex of an unborn child instead of just dangling a ring suspended on a string over the pregnant mother’s abdomen. This old tale says that if the ring swings from one side to another, it is a baby girl. But in case it swings in a circle, it is a baby boy. Fetal heart rate monitor’s results are not as much fun. On the other hand, these test readings are definitely much more precise.

Baby’s Heartbeat and Gender Prediction

There is an old rumor that the fetal heart rate can predict the gender of the unborn child. Just for instance, in case the fetal heart rate is consistently over one hundred and forty, it is a baby girl and if the heart rate is under one hundred and forty, it is a baby boy. Sorry to disappoint you – this is not true.

On the other hand, one scientific study published back in 2009 in the American Journal of Obstetrics and Gynecology found that there’s a slight difference in the fetal heart rates of baby boys and baby girls throughout the labor. Physicians found that during labor baby girls had faster heart rates when compared to baby boys.

Dark Nipples and a Baby Boy

So, do dark nipples during pregnancy indicate a baby boy? Unfortunately, dark nipples during gestation period have nothing to do with the sex of the unborn baby. On the other hand, this sudden change has a lot to do with the increase in progesterone (this hormone is one of the steroid hormones) as well as with the melanocyte-stimulating hormone (this hormone is well known as a mediator of skin pigmentation) causes dark areas of the pregnant woman’s body to become much more pronounced. Therefore, nipples as well as birthmarks and even moles may look a lot darker throughout the gestation period. What’s more, a dark line can appear down the middle of the expectant mother’s stomach. This line is usually referred to as the linea nigra (or simply the black line). It goes from above the navel all the way down to the pregnant woman’s pubic area. Luckily, these darkened areas fade right after childbirth.
