NUB THEORY aka Angle of the Dangle Theory at 12 weeks pregnant!

Video taken from the channel: The Mims Life


If your baby’s nub is angled higher than 30 degrees in relation to its spine, that indicates your baby is a boy, according to nub theorists. Now, no one is saying to whip out a protractor to. Using this method is highly accurate. When your baby’s nub (genital tubercle) is forming and visible around 12 weeks, the angle of the dangle can assist in predicting the sex of your baby.

What is a nub? Before about 15 week gestation, both males and females have genital tubercles, also known as a nub. The nub theory is the theory used to decide whether you are having a boy or a girl.

Often called the ‘angle of the dangle’. Boys angle upwards and girls lay flat, This is a FACT and not a theory! The genital tubercle develops into either a penis or clitoris and this is possible to view from around 12 weeks by analysing the. The nub theory is all based around the angle of your baby’s nub. If the nub is pointing upwards, at an angle of more than 30 degrees to the spine, the baby is likely to be a boy.

If it’s pointing downwards, straight out or upwards at an angle of under 30 degrees, the chances are you’re having a girl. The gender of your baby depends on the angle of the nub of your fetus and also its shape and length. Suppose the nub happens to be tipping upwards, in an angle not less than 30 degrees of the spine of your fetus, mostly your baby will be a male.

The Nub Theory uses the “angle of the dangle” to determine whether the baby is a boy or girl. The nub begins to change around 11 weeks, but analysis of the nub angle is most accurate beginning at 12 weeks through 14 weeks gestation. Learn the timeline and characteristics of the genital tubercle in our Nub Theory Guide. The angle of the dangle (as its commonly referred to) is not the only gender marker we look for when predicting your baby’s sex, there is so much more that we take in to account.

The spine could be curved/straight due to your baby’s position in the womb, the exact gestation of the fetus, the bladder position which helps to determine the angle. It’s the angle of the dangle: Boy nubs angle upward Girl nubs lie down flatter Note that isn’t a theory; it’s a known biological fact, and is due to the genital tubercle’s development into a penis or a clitoris. The nub angle can be seen in a profile image of the baby. Look for the angle of the nub compared to the baby’s. It is otherwise referred to as the ‘angle of the dangle’ and may indicate if the baby is a girl or a boy.

If the angle of the nub is over 30° from the spine, it is said to be a boy. If the angle is below 30°, it is said to be a girl (2). The angle of the nub is determined by carefully examining the ultrasound scan picture.

The theory simply states, during early pregnancy on 12-week ultrasound, if the angle of the nub is beyond 30° from the spine, it is considered to be a boy whereas if the angle is below 10° then it is considered to be a girl.

At the 20-week anomaly scan it can be possible to determine the sex of the baby, depending on the baby’s position.

  • @chall1011 I know it’s not a cord. It could very well be a penis and the ultrasound is just picking it up weird. Or it’s swollen girl parts which majority of babies goods are swollen at this stage. No telling what this baby is?

  • I honestly never knew this was a thing until this video! We’ve got another scan tomorrow and if they still can’t tell me the gender I’ll definitely be letting you guys have a guess! xx

  • We’re team green but I’m totally guessing too lol but I can’t see the darn nub in our photos from 12 weeks but this video was helpful

  • Definitely a baby boy!! The risen nub shows the nub full. Your other scan shows a partial. And potty doesn’t show true gender! Congratulations on your son xx

  • I agree, I vote girl. Wish you a healthy pregnancy!

    After two girls I was super anxious, so I did the at home finger prick test and it said boy at around 10 weeks������ I was so happy it was also correct at my anatomy scan as well.

  • Want to find out your babies gender! Find out at 12 weeks. Check out the “nub theory club” on Facebook. They’ll tell you if it’s a boy or a girl.

  • Cute video. That’s for sure a little boy haha�� In my son’s ultrasound he was holding his private�� and the US tech and I thought that was so funny. Lol BOYS!

  • That nub was definitely stacked not so much as forked. I’m commenting before I look for an update. But my guess is Boy. We shall see how I am on my nub skills:)

  • Girl. when i went with my friend to her girl’s ultrasoundthe tech said that 2 lines indicated a vagina. I would definitely say that looks like a girl.

  • Hmm I can hardly even tell what’s leg and what’s nub! But I reckon maybe more parallel than 30 degrees. So my guess is girl! But girl or boy… mini-Atkinson is exciting enough for me! x

  • my daughter at 12 weeks had nothing there at all hanging down, the 3 lines were in the pelvic area, unless that is a cord we are seeing an then the 3 lines?

  • This was soo sweet I loved feeling my baby’s’ hiccups and I agree the hardest thing about being pregnant during the holidays is no wine lol loved this! New friend here xoxo

  • Gender of baby determination. Gender determination by photo of parents only. To do this I have an account and a group on face book. Group is called Baby gender by parents photo\

  • I say GIRL! Lily’s looked just like that. In fact I was scared she was a boy because things looked all swollen down there in the ultrasound! but yes, I say girl:)

  • hey could u just tell me if its a boy or girl..?? my first baby nd just had 1st scan last week and cant wait for 2nd scan so if u guys help me would b great..

  • Im thinking girl too for you! I never found out with all 3 of my pregnancies but my 1st 2 I swore a boy and I was right my 3rd was also a boy but I kept flip flopping with what I thought he was! It was the hardest bit finding out but I wanted the surprise! Love the gender tests you keep doing!

  • Oh my god I have been going through every single theory as well to maybe find some insight on what my baby is! We find out very soon thro ultrasound and we cannot wait!

  • I’ve got some more opinions. And the verdict is… Emma and my Mum both reckon girl. My Dad still hasn’t seen it. There’s a few more to add to the tally then! x

  • I was 12 weeks when I found out i was having a boy and girl. the longest 12 weeks ever! lol i was so impatient and i was anxious to know!

  • Hmm I can hardly even tell what’s leg and what’s nub! But I reckon maybe more parallel than 30 degrees. So my guess is girl! But girl or boy… mini-Atkinson is exciting enough for me! x

  • Hey! I found this nub info..And was surprised you did a video of it. I’ll make a picture Video of my 13 week “nub”shot” And get your opinion…:-)
    I can’t believe after 8 yrs! we are having a baby! I followed your first Pregnancy:-) May make it a video response to this one of yours,so it’s easy to find. If you don’t mind.:-)

  • I wore maternity leggings pretty much my whole pregnancy instead of buying maternity jeans lol. I only bought a few maternity shirts and one pair of jeans

  • Your hilarious!! I couldn’t wait. I’m like a you type A also. My 1st wouldn’t co operate with the tech. Either time. But my instinct was it was a girl. And it was. 2nd was a boy. It’s much easier to see if it’s s boy obviously the dangle. Lol. ��

  • Mine has what they call a straight nub so according to this theory It’s supposed to be a girl. It is not and it is in fact a boy. Clearly a boy. Lol! The Harmony bloodwork done at 12 weeks is 99% accurate not this nub theory. Sorry to be a spoiler

  • I enjoyed this, girly! Congratulations on your pregnancy and how exciting to know you’re having a boy! I love that you don’t really need maternity clothes at this point in your pregnancy. You only have a few months left; amazing!!!! I’m very excited for you!

  • Hi where is the link so I can post my scan me and my partner are bickering we just can’t agree on what we think our baby is haha we need your help lol

  • I found it lol I just posted my scan picture under “can you help us lol” if you can can you take a look at it and let me know your opinion ❤️ Thank you xx

  • I just watched your video about the nub and skull theory and my guess was that you’re having a boy. The baby’s head shape is more bulky in the previous video and according to “skull theory” that means a boy. Lol congratulations on your baby boy ����♥️

  • At 12 weeks during the first screening test we have in Europe (combine test) the doctor told me the gender at 90% certainty. She was right of course because the morphology is different even at this stage.

  • Try the intelligender test! Its fun! I have 3 boys an didnt think I’d ever have a girl. I found out at 10 weeks with my 4 an according to the test it was a girl. It was right. Now im 12 weeks pregnant with my 5th an i truly think uts a boy! Took a test at 10 weeks an it said boy! Still awaiting for 100% but i dont have any doubt its not. The intelligender test results i think are around 98% right but i could be wrong. Good luck! Btw i think your having a girl too:)

  • I got to know my two daughters gender in a dream before first scan. First one I was a bit skeptic but the second time I knew the sex with full confidence. Two lovely girls.:)

  • Ive not had any children myself yet but every scan picture I have looked at, 90% of the time I have got it right due to shape of the skull! ��
