Similar to the Ramzi Theory, the nub theory says you can tell the sex activity of your baby at your very first ultrasound. So information technology'due south popular with those who can't await to find out if they're having a little daughter or boy.
Nub Theory: what is information technology?
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-xiii weeks, turning into a penis in males and a clitoris in females.
The idea is that, if you can go a clear view and baby isn't doing fetal gymnastics, yous can predict the sex of your babe based on the bending of the nub. Co-ordinate to this theory, the 'angle of the dangle' will indicate whether a baby is a male child or girl. It'southward said that if the nub is over 30 degrees upward from the spine, it'south a boy.

The nub is at a much steeper angle upwards from the spine, indicating that this could be a babe boy. At present, we're not certain what 30 degrees looks similar on an ultrasound. Just if you lot were to draw a straight line on the ultrasound along the bottom half of your baby's spine (near their bottom) y'all can come across whether the nub is pointing conspicuously upwards and away from that line or not.

If you compare the angle of your baby'south lesser/spine to the bending of the nub, and it sits horizontally in line with the spine or even points down towards it, believers would say this shows a little girl.
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 petty wishy-washy, there are studies to back information technology up. A 2016 study looked at the accuracy of the Nub or 'Nib' theory and the results were surprisingly authentic. The researchers found that out of 672 cases, sexual activity decision was possible 90 percentage of the time. And the baby's gender was correctly predicted 87 pct of the time.
"While the percentages [of those who accurately guess their baby'south gender using the Nub Theory] may seem pretty high, it'southward not as easy as information technology sounds." says Patricia Santiago-Munoz, M.D. "There are a number of variables that can bear on whether we can determine gender every bit early as 12 weeks."

Patricia explains that you'll have to promise for co-operation from your babe during the 12-week browse, as getting a skilful enough photo to employ for the Nub Theory all depends on the bending of the baby:
"First, your baby needs to be in a position for us to get a good photograph. That includes not having their legs closed!" If you lot can get a flick of them laying down on their side, that should provide you with a skillful view of the nub. Patricia as well explains that the quality of the ultrasound photo may besides be afflicted by other factors too.
"A mother'south weight also affects our ability to predict gender. The more than body tissue the ultrasound waves must travel through, the fuzzier the images may be. The 2016 study constitute that a body mass index below 23.8 was the best cutoff value for gender prediction at 11 to thirteen weeks. The odds of an accurate prediction autumn for women above that number."

Can the Nub Theory be incorrect?
Yes, the Nub Theory can definitely be wrong. Despite the loftier percentage of correct gender predictions from the study in 2016.
"In that location's a chance that our prediction merely will 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 bespeak up or the umbilical cord is mistaken for a penis.
"While gender prediction is much more authentic during the 20-week ultrasound, in that location's still a chance it tin can be incorrect. I recently had a patient who was expecting a male child. She and her hubby had a proper noun picked out and had painted the nursery for a boy when they institute out shortly before giving nativity that they actually were having a daughter. They were shocked but took the news in stride.
"I want to stress that the main goal of claret tests and ultrasounds during the first trimester or early on second trimester is not to determine gender."
"Ultrasounds are used to screen for certain conditions and check whether in that location is something noticeably wrong with your babe. While we understand you lot may be eager to learn the gender, try not to be upset if your sonographer tin't predict information technology."
In determination, the Nub Theory is a fun way to guess your baby's gender later your 12 calendar week scan. Though, probably best to await until a medical professional person has confirmed your baby'due south sexual practice. Or until y'all've met your baby in person, before committing to any kind of color scheme or wardrobe.
