This is pretty cool!!
Finding out the gender of the baby is one of the biggest things many families look forward to during pregnancy, whether they have a preference or not.
Most average pregnancies under OB/GYN care in the United States undergo two ultrasounds -- one at the end of the first trimester, around 9-13 weeks, and another around the end of the second, around 18-22 weeks, the latter being the "gender ultrasound" most frequently.
But what if you could find out at that first ultrasound, and NOT because you can see baby's family goods? According to a certain study, you can with 97 percent accuracy!
Researchers did a transvaginal ultrasound (you know, the fun wand up your vagina) at 6 weeks on more than 5,300 women and hypothesied gender due to one marker. Then a transabdominal ultrasound (the one on your belly) at 18-20 weeks, and their method of gender determination was right 98-99 percent of the time!
Obviously you're wondering what they could possible see at 6 weeks gestation that would tell them anything about the sex of the baby, right?
Or more specifically, the location of the placenta -- 97.2 percent of boys had their placenta on the right side of the uterus at that 6 week ultrasound, and 97.5 percent of girls had theirs on the left. Crazy, isn't it? According to their study, this method should be considered "highly reliable" in determining gender within the first few weeks of pregnancy.
I tried to look at ultrasounds of mine and many of my friends, but I'm no radiologist, so I'm not quite sure where the placenta is, especially in some of the less clear images. Apparently if your first ultrasound was transabdominal, the image is flipped, so you'd reverse the sides.
Get out your ultrasounds, ladies! Was this true for you?
