Pregnancy is such an heady – only slow – time! During that beginning trimester y'all're excited to know as much about your infant equally possible; like the gender. Usually you lot accept to wait until your 18-22 calendar week anatomy browse to be in with a chance of finding out, but the Nub Theory is a popular mode for parents-to-exist to predict their baby's gender at simply 12 weeks.
Unlike other methods that apply astrology to predict a babe's gender or onetime wives tales about pregnancy to guess if you're carrying a boy or a girl, the Nub Theory uses the 12-week ultrasound scan movie to predict the sex of your baby more than accurately.
Similar to the Ramzi Theory, the nub theory says you tin can tell the sex of your baby at your very first ultrasound. And then information technology's pop with those who can't wait to find out if they're having a little girl or boy.
Nub Theory: what is it?
The Nub Theory is all about something called the genital tubercle, or a 'nub'. All babies have this between their legs and it develops between 11-13 weeks, turning into a penis in males and a clitoris in females.
The idea is that, if you tin get a articulate view and baby isn't doing fetal gymnastics, you can predict the sexual practice of your babe based on the angle of the nub. According to this theory, the 'angle of the dangle' volition point whether a baby is a boy or girl. It'southward said that if the nub is over xxx degrees upward from the spine, it's a boy. However, if it'south under that, then information technology'due south a girl.
To be able to apply the Nub Theory your babe needs to be in a articulate contour position, so the length of their spine is visible.

The nub is at a much steeper angle upwardly from the spine, indicating that this could be a infant boy. Now, we're non certain what 30 degrees looks like on an ultrasound. But if you lot were to draw a straight line on the ultrasound along the bottom half of your baby's spine (about their lesser) you tin meet whether the nub is pointing clearly upwards and abroad from that line or non.

If you compare the angle of your infant's bottom/spine to the angle of the nub, and information technology sits horizontally in line with the spine or even points down towards it, believers would say this shows a little daughter.
Nub Theory accuracy: what the experts say
The Nub Theory, does what it says on the tin. It's a theory. While it may sound a lilliputian wishy-washy, there are studies to back it up. A 2016 study looked at the accurateness of the Nub or 'Nib' theory and the results were surprisingly authentic. The researchers establish that out of 672 cases, sexual activity determination was possible ninety per centum of the time. And the baby'south gender was correctly predicted 87 percentage of the time.
"While the percentages [of those who accurately guess their baby's gender using the Nub Theory] may seem pretty loftier, it's non equally piece of cake as it sounds." says Patricia Santiago-Munoz, Thousand.D. "There are a number of variables that can bear on whether we can determine gender as early every bit 12 weeks."

Patricia explains that you'll have to hope for co-operation from your baby during the 12-calendar week scan, as getting a adept enough photo to apply for the Nub Theory all depends on the bending of the baby:
"Start, your infant needs to exist in a position for us to get a good photo. That includes non having their legs closed!" If you can get a moving-picture show of them laying down on their side, that should provide y'all with a good view of the nub. Patricia also explains that the quality of the ultrasound photo may as well be affected past other factors also.
"A female parent's weight also affects our ability to predict gender. The more body tissue the ultrasound waves must travel through, the fuzzier the images may be. The 2016 study found that a body mass index beneath 23.8 was the best cutoff value for gender prediction at 11 to xiii weeks. The odds of an accurate prediction fall for women above that number."

Can the Nub Theory be wrong?
Yes, the Nub Theory tin definitely exist incorrect. Despite the high percentage of correct gender predictions from the study in 2016.
"There'southward a chance that our prediction merely volition exist wrong," says Patricia. "We tend to over-predict boys more often than girls. This can happen, for example, if the baby is developing slowly and the tubercle hasn't begun to point upwardly or the umbilical string is mistaken for a penis.
"While gender prediction is much more than accurate during the 20-week ultrasound, at that place'south still a chance it can be wrong. I recently had a patient who was expecting a boy. She and her married man had a name picked out and had painted the plant nursery for a boy when they establish out shortly before giving birth that they actually were having a daughter. They were shocked but took the news in pace.
"I want to stress that the master goal of blood tests and ultrasounds during the showtime trimester or early second trimester is not to determine gender."
"Ultrasounds are used to screen for certain conditions and check whether there is something noticeably wrong with your baby. While we sympathise you may be eager to learn the gender, endeavour not to be upset if your sonographer tin can't predict it."
In conclusion, the Nub Theory is a fun way to judge your baby's gender afterward your 12 week scan. Though, probably best to look until a medical professional has confirmed your babe's sexual practice. Or until y'all've met your baby in person, earlier committing to any kind of color scheme or wardrobe.
