Pregnancy is a time of remarkable changes in the body. Some of these changes have often sparked curiosity and led to the creation of numerous old wives' tales related to different aspects of pregnancy. One such common belief is that expecting mothers who experience higher levels of nausea are likely to give birth to a girl. While many such tales are proven baseless, this hypothesis seems to have some grains of truth, substantiated by recent data analysis carried out on the popular What to Expect app.
The belief that morning sickness may indicate a female child has a longstanding historical presence. It dates back to ancient Greek literature, effectively turning it into more than just a tale passed down generations. The foundations of these ideas are rooted in observations, but there's more to it than that.
The data analysis at What to Expect involved studying logged symptoms from nearly 118,000 mothers on their platform. It was found that mothers who are expecting a girl reported feeling nauseous more frequently than those expecting a boy. This contributes significantly to the understanding of why morning sickness may indeed be indicative of expecting a girl.
On the What to Expect app, the mothers could log their symptoms and share the sex of their baby, providing a tangible way to relate the symptoms to the baby's sex. A review of more than 1.8 million symptoms logged by 117,730 mothers showed a higher propensity for nausea amongst those expecting a girl.
Furthermore, it was found that mothers expecting girls were 3.2% more prone to reporting nausea or vomiting compared to those with boys. This was the largest difference amongst all the 67 tracked symptoms based on reported baby sex. These findings have been validated by anecdotal experiences shared by various mothers.
One member of the What to Expect community shared that while she was hardly sick during her boy's pregnancy, she experienced sickness every single day with her daughter. Similarly, another mother highlighted that she encountered morning sickness only during her daughter's pregnancy and never experienced it throughout her previous two pregnancies with boys.
However, the scenario is not the same for everyone. For example, a member shared that she experienced nausea during her son's pregnancy but not with her daughter. Another member had severe nausea during the first trimester with her son.
The prevailing belief of morning sickness being indicative of a female child has persisted for centuries. Caitlin Baulch, a faculty member at the University of Minnesota Twin Cities who studies old wives' tales, relates this belief to an ancient Greek book called Aphorisms by Hippocrates.
While part of this connection can be attributed to observations and experiences, other factors might have made it prevail through centuries. Gender bias plays into it to some extent. Many of the negative symptoms are associated with carrying a girl while positive ones are attributed to having a boy. This has led to the belief that girls make mothers experience more sickness.
This is corroborated by another mental phenomenon called confirmation bias. Gender prediction tales have endured due to them being just about right half of the time, further reinforcing the belief. There is also statistical evidence to support — What to Expect's data aligns with a 2021 study exploring similar variables.
Why might having a girl make a mother more nauseous? While more research is required, it seems that this might be linked to hormones. Specifically, nausea and vomiting during pregnancy are tied to higher levels of the human chorionic gonadotropin molecule, also known as hCG, which is tested to confirm pregnancy.
If you're wondering when you can find out whether you're having a boy or a girl, there are a couple of more reliable methods. At the gestational age of 10 weeks, a simple blood test called Noninvasive Prenatal Testing can detect the baby's sex. Alternatively, the 20-week anatomy scan, inspecting your baby from head to toe, can also determine the baby's sex.
For the expectant mothers struggling with nausea, small measures could provide relief. Eating a small snack as soon as you wake up might be helpful. Also, instead of having three large meals a day, consider having six smaller portions. Maintaining oral hygiene and keeping your mouth refreshed could also potentially help reduce nausea.
It would be worthwhile to experiment with taking your prenatal vitamins with food. If you suspect that the vitamins might be contributing to your nausea, don't hesitate to consult your doctor for alternatives. However, it's reassuring to know that nausea during pregnancies is usually temporary and would likely fade with time.
Despite the data and anecdotes suggesting a higher probability of having a girl if morning sickness has been experienced, there is no absolute certainty. Many mothers have had boys even after experiencing bouts of nausea. However, the statistical data serves as a piece of interesting information during a beautiful yet unusual period of life.
Anecdotes and personal experiences from members of the What to Expect community support that each pregnancy has its unique symptoms. Some have reported nausea only during a girl's pregnancy, while others have reported similar symptoms during a boy's pregnancy.
In a nutshell, the data analyzed from What to Expect shows a possible link between pregnancy nausea and carrying a girl. This study paves the way for additional research and possibly additional clarity. Nonetheless, every pregnancy is unique, and it's important to recognize that there is no absolute certainty with these symptoms and the baby’s sex.
