It uses sound energy and not radiation, such as X-rays, to generate images of the fetus.ĭuring a transabdominal ultrasound, a pregnant woman lies on her back while a clear gel is spread on her belly, according to Johns Hopki n (opens in new tab) s Medicine. Ultrasound is a safe prenatal test, according to research published in the journal Ultrasound in Obstetrics & Gynecology (opens in new tab). Is ultrasound a safe way to predict gender? In addition, ultrasound can identify certain birth defects, such as Down syndrome and spinal abnormalities, and investigate pregnancy complications, including miscarriage, according to the Mayo Clinic. The scan is also done to see if a woman is having more than one baby, as well as to determine the location of the placenta and umbilical cord. It's typically during the second ultrasound that parents can learn the sex of the baby. ![]() This early ultrasound is often done to confirm a pregnancy, detect the fetal heartbeat and determine the due date, according to the Mayo Clinic (opens in new tab).Ī second ultrasound is usually done between the 18th and 22nd weeks of pregnancy to make sure that the baby is growing and developing properly. But the common prenatal scan wasn't intended as an exam to find out the baby's gender it was meant to image the developing fetus for other medical reasons, he said.Īlthough the test can be done at any point during pregnancy, women typically get one during the first trimester. hospitals have used ultrasounds since the late 1970s and early '80s, Carr said. Pregnancy diet & nutrition: What to eat, what not to eat Mood swings & mommy brain: The emotional challenges of pregnancy So essentially – a square-shaped little skull for a boy, and round itty bitty head for a girl.- Having a baby: Stages of pregnancy by trimester ![]() For boys you’re looking for a more square skull and jaw because men have lower and more sloping foreheads.įor a girl, the top of the head is rounder and tapers at the top and the cheekbones are less pronounced. This method of gender prediction is based on the shape of your unborn babe’s skull. This method is based on the genital tubercle or the ‘nub’ that babies have between their legs between 11 and 13 weeks. If the nub points up more than 30 per cent, it’s a boy. The theory goes that if the nub is pointing up less than 30 per cent from the spine, it’s a girl. There are entire forums dedicated to the gender prediction nub theory, where you can ask thousands of people what they think you’re having based on your ultrasound and the direction of bub’s genital ‘nub’. However, studies since have disproved the theory (but it’s still fun to see if it’s accurate for you). On the right side of the uterus for a boy and on the left side of the uterus, for a girl. According to a research paper more than 5000 women had an ultrasound at six weeks to see where their placenta was forming, and they had a follow-up ultrasound at 18 to 20 weeks to find out their baby’s gender.Īccording to the study, the side that the placenta had formed on was correct in predicting the baby’s sex around 99 per cent of the time. Placenta positionĪlso known as the Ramzi theory, this method of gender prediction is all based on the position of the placenta. The labia lips on either side of the clitoris sort of looks like a little hamburger, or three lines. For a boy, you’ll see a ‘turtle’ – the tip of the penis peeping ever so slightly from behind the testicles. A ‘hamburger’ sign will usually mean it’s a girl. It’s pretty much what an ultrasound tech is looking for if they’re checking bub’s gender. If there’s a clear ‘between the legs’ image, you may be able to spot either a hamburger or turtle (really!). So, here are four ways to ‘predict’ baby’s gender from an early ultrasound. ![]() While mums-to-be now have the option of having non-invasive Prenatal Testing at 10 weeks, which is 99 per cent accurate in predicting gender, for those opting for the traditional 12-week ultrasound, there’s a bit of fun to be had in trying to guess whether there’s a boy or girl on board. In fact, there’s one ‘scientific’ method that claims a baby’s gender can be predicted as early as six-weeks, using an ultrasound. ![]() And apparently there are clues hidden in that first ultrasound image that may just tell you if you’re having a boy or a girl. The grainy, black and white 12-week ultrasound that makes it all seem so real.
