The nub theory

Has anyone heard of or tried the "nub" theory? It's for an ultrasound 12-14 weeks and it has to do with the angle of he baby's nub and determining whether it's a boy or girl. 30 degree angle or more of nub from baby's spine = boy and parallel to spine= girl. We are not finding out what we are having with this pregnancy so I enjoy trying these different gender predictions. Here is the pic of our lil one. Not quite sure if what I think is the "nub" really is but as of now I'm thinking girl. Post nub pics. What does everyone think?

Re: The nub theory

  • Not an expert..but not a good nub shot. I'd say you have a 50/50 chance!
  • Loading the player...
  • Too early for this...

    50/50, OP.
  • I don't really understand... you don't want to know the sex but you want us to try to help you figure it out?

    Huh, I just skimmed and missed that part. Just a touch confusing there, Op.
  • I don't see a nub here. Those blips could be anything from a limb to a hip to the cord. These things are fun to guess at though :)
  • Never heard of this. I thought boys and girls looked the same until further along when a girl goes back in??

  • They do look the same but supposedly have different angles at a certain stage before developing into the genitalia you'll see at the anatomy scan to say for sure what the sex is. It's definitely an interesting theory though.
  • Never heard of this. I thought boys and girls looked the same until further along when a girl goes back in??

    Here is a link pay attention to the last section at the bottom...I think a lot of methods are wives tales, but this one kinda isn't. You need a good shot though, without it there's a lot of guessing.

    Nub theory is the same as Ramzi theory and Skull theory and all of the other BS sex determination theories out there that claim to have a scientific basis but always have the disclaimer of "wait until the anatomy scan before making any major decisions/purchases". Doesn't inspire the most confidence, does it now?

    It's 50/50, whether it's male or female. These things are typically fun to do with your friends and family, not so much with random people on the internet that you've never met or really talked to.

    Also, you've posted a profile shot with no nub whatsoever. Just wait the extra 6-8 weeks for the anatomy scan if you actually want to know, or wait until birth if that's what you want to do. On every other part of the bump, these go down really poorly (take a swing over by 1st/2nd trimester of you don't believe me). I'm actually really confused why this has gone down so relatively well thus far. Of course, you're always free to post what you want, just giving a heads up that the responses you (general you) get might not be quite what you were anticipating.

    I'm going to disagree with you on this. Many techs and doctors believe this theory and their comments are usually correct. The problem with this "theory" is that images are often blurred or inconclusive and people make assumptions not actually knowing where to look or what to look for. If you have a perfect ultrasound that is clear and you know what you are looking for, you have a very good chance of figuring out gender.

    But it gets annoying when people post pics and ask ...there's other forums for that. Like Ingender. But I wouldn't automatically debunk this one, it's the only one that can actually work. But I agree, this isn't the forum for it. There are more appropriate places on the Internet for it.

    Edited to add a link to a page that explains more & cites numerous scientific studies of the accuracy at 12 weeks.

  • @Bear14+ I just wanted to thank you for being rational and civil with your response. After some of the insane blow ups on here in recent days its oddly refreshing.
  • I believe the nub theory has some weight to it. It has some research to back it up. I wouldn't go decorate the nursery over it but there is some truth to it. It was right for me with my son last time too! I don't know if that's the nub in the picture but if so I'd guess girl
  • No there is no validity to any of these theories. The only reason why people are correct about these theories is because there is a 50/50 chance!
  • @crdo ur right there really wasn't anything nasty. I think I was just being sensitive/hormonal earlier. Haven't really posted before and didn't know what do except. Just sharing and looking for opinions from ladies who are going through the same things at the same time. I will have fun doing a bunch of other gender predictors with friends and family until we meet our lil one in June!

    I actually disagree. This is a study:
    https://biomed.papers.upol.cz/getrevsrc.php?identification=public&mag=bio&raid=264&type=fin&ver=3

    As well as plenty of info here and more links to studies:
    https://www.ingender.com/gender-ultrasound/Nub-Theory-Accuracy.aspx

    If you are trained and know what to look for with accuracy (plenty of OB's practice this) it is in fact possible to determine fetal sex at 12-14 weeks. It is not 50/50. The problem is all of the people who post pictures trying to figure it out with incorrect information on what to look for, photos that do not show, or those who try to guess at 11 weeks when it's too early.

    Like I said before, this isn't the forum to be asking questions like this. However, show me your information that debunks this because it has been proven to be a very reliable method. (Versus Ramzi, skull, etc which are all not reliable).

    Like my tech said to me when I was pregnant with my son, don't go buying boy clothes, but I'm pretty sure. Because she knew the anatomy and what she was looking at.
  • I agree with @Bear14+ on this because there are trained and fully licensed OB/GYNs who told me about finding out the gender with the nub theory. Also, because it's called "theory" it doesn't mean it's junk. Most things are referred to as "theory" in science because our knowledge is constantly changing.

    The problem with this method is that it's often hard to get a clear view of the nub, and even if you do the baby has to be totally straight. It's not the easiest method so I think this is why it's not popular. My OB friends have admitted that it is very difficult to see the sex this way because it depends on baby being in the right position, but that they do try to look when they do ultrasounds as early as 12 weeks. Maybe German doctors are more into this than Americans, but my friends treat it as a valid thing and I trust their opinion.

    All good! Have fun.
  • @CopperLane I asked the tech at my first appointment what the earliest they would be able to determine sex was and they said they won't speculate until the anatomy scan. There are theories that claim to work before that but they aren't reliable enough for the tech there to feel comfortable making a guess one way or another. Nub may have legitimacy on paper but unless that can translate into real life success, it isnt worth it to me. I would rather wait until a more legitimate guess can be made than have mind on one sex and have it end up going the other way.
  • Interesting theory! Thanks to the poster who linked the research, too. I can't tell based on the ultrasound but I'm not too skilled !

  • Unlike Ramzi and some of the other theories that are basically glorified wives tales, nub theory is used by many ultrasound techs (not all, but many). However, the pic you posted doesn't show the nub. I see that little blip that may look similar to the nub, but I don't think that's what it is. Sorry :-(
  • Everytime I read 'nub' I think penis.

    @Nikid27 I don't think it's a matter of who is right or wrong. Don't feel like you have to explain yourself to anyone! OR get permission from others on what is "acceptable" according to them. I think you are just trying to have fun and get support from other moms. After all, this is one of the main reasons a community board exists. Keep posting what you like (as long as it's not offensive). By no means what you posted was near offensive. I do agree that maybe some people are just hormonal and sensitive. I hope they find comfort in their second trimester.

    Every time I read this, I laugh.

    No one said OP couldn't post, no one said she needed permission, no one said anything about being right or wrong. OP said she was the one being hormonal and sensitive.

  • Sorry, I guess joking isn't allowed. I hope my sarcasm is just a first tri symptom and I won't be like this the whole pregnancy.

    I hope you find comfort and lose that terrible sense of humor in your second trimester! :wink:

  • Just trying to be supportive to my fellow Bump ladies, and this is honestly the first time I seen any level of trolling/bullying on these boards. Yes, in my eyes "your sarcasm and humor" is masking your foul attitude. Stop mocking others! Unreal....
    @hockeyfan42 @mdargie
  • I am not sure what facts you have provided? Besides stating your opinion, as I am stating my opinion. You are deliberately trying to elicit a negative response from others. Just look at the last couple posts where you and another are mocking me? This is honestly silly. I am done with this. Agree to disagree and move on?

    I stated facts regarding the original discussion in response to your initial post. You seemed to be a little confused about what had occurred. I made a joke in response to a statement you made that I found to be condescending. ::shrugs::

    I do not appreciate your bullying comment. Not sure what there is to "agree to disagree" about. Good luck to you with your pregnancy.

  • I can't honestly believe that
    A. This is the first time you've seen someone make a joke
    B. That you think anything in this thread could be construed to be trolling or bullying. FWIW on most boards here, posting an ultrasound pic and asking what we think the sex might be is flamed wayyy more than this post. Get a blood test or wait until your anatomy scan.

    Yeah I guess we can agree to disagree

    ^^This! Take a stroll over to 2nd trimester. There's at least 3 recent sex determination threads, all went down in the same way, a way that was much less positive than this one.

    This is getting very boring. It is very simple, 1/2 the group want to discuss old wives tales for fun, the other 1/2 don't. Yes, we understand that they are not all 100% science based and we are OK with that! We know how 1/2 the group thinks it's a load of rubbish but it doesn't need to be said each time. Jokes amongst people who don't know each other are likely to risk coming across as mocking. If you don't like nub/ramzi etc just don't click into the thread......simple. End of rows!

    I agree. I don't click on the threads I'm not intetested in.

    The problem is that many of us who don't want to deal with the pseudoscience ended up here because most other internet forums are very big on the pseudoscience BS. I spent all of 2 days on baby center before being driven insane by it being everywhere. Looking at the other BMBs, ours seems to be unique in having a group of people who want to do the old wives tales, most other BMBs and the trimester boards are against nub/skull/Ramzi/is my doctor wrong because baking soda said differently etc. It just feels like people are trying to change the tone that the rest of this site tends to hold regarding sex deteminination theories. Maybe it's just me and my hormones though.
  • Honestly, I was speaking independent of whether or not "the nub theory" was valid. I felt the OP had her back against the wall with comments about how these threads never end well, share with friends and family only, just wait for the gender reveal u/s, mocked for sharing a "superficial understanding." Please do not misunderstand, it's your right to disagree...just do it in a tactful manner! Be considerate of others. Also, wish someone well or dont say anything. Don't be half-hearted about it...it certainly reflects on your character.
    Especially if you're a FTM just trying to get support from others. @Atlast111 I agree that it comes across as mocking when it's a complete stranger over the internet. Just don't click the thread!
