dumb q on nubs

[atomic sagebrush]

Ok, I am confused. Is the angle of the nub REALLY that make-or-break when it comes to gender? People seem to put a lot of emphasis on the angle of the dangle but when I look at an u/s pic, some of them just look like peeners/balls and some look like VJs.

People post sets of pics where the angles seem different to me on every shot, but the sum of the parts seems more girly or more boyish to me overall.

So my question is, is it really JUST the angle? How much does gestation matter - I mean like the diff. between 12 and 13 weeks??

ETA - Please understand, I've read the theory and understand, so I don't need a real basic explanation of that, it's just that babies are always moving and it seems to me that esp. with a boy, the angle could change (and does seem to) so I'm just curious how much weight to give the angle as opposed to something that looks identical to a penis but happens to be pointing down. I hope that makes sense!!

I don't think it is all about the angle but more of the shape IKYWIM? My nub was staight but a definate blob on end!!! Much different to my girls who were straight but two horizontal lines stacked on top of each other from end to end.

I think the nub needs to be captured really well for it to be accurate. And the spine as straight as possible, if the baby is curled then the angle can look really off which is why the shot looks different in different pictures. I don't think the shape matters so much at all tbh, I definitely think it's all about the angle, which is why the nub theory is also named "angle of the dangle"
All nubs look different to me, some girls nubs are thin and forked and some are thick and look more boyish but then both have been confirmed girls. Some boys you can really tell that they are boys and some not so much because babies develop at different rates. Sometimes you can still see a nub at 15-16 weeks. As for the weeks, 11 weeks is still 50/50 so isn't a good week for guessing at all, 12 weeks is about 75% accurate and 13 weeks is the best for guessing at around 85% accurate. I am definitely not an expert though so if anyone wants to explain a bit better then feel free.

I think some nubs can be obvious and I think if you wait until 13 weeks, it can be VERY obvious if it is a boy. Any nub from 11 weeks is just a random guess on here and the angle doesn't even apply yet and we have a lot of eager moms getting early NT scans.

I think at 13 weeks, it is a solid assumption with the correct view- straight spine and leg out of the way. I see lots of pics that the leg is clearly blocking any nub and many people guess girl because they do not see anything sticking up.

I went to a specialist for my NT scan due to AMA and he told me that it was accurate and he could tell me what it was with pretty high certainty. I was 13 weeks though.

I was JUST thinking this. ALL nubs looks girly to me lately on angle. The whole 'blob' on the end thing is not something I 'get' either.

After researching TOO much...I put my pic away today. It's so 50/50 for me either way. Angle was stressful enough, without deciding if there is a blob...and what if the blob is a shadow?! Curious what everyone else thinks.

For the life of me, I cannot figure it out. I have looked at a TON of ultrasounds trying to figure it out. I NEVER get it right.

I looked through the galleries on IG, and honestly, there are confirmed boy/girl nubs that look identical to me. I am not good at guessing, so I don't ever post guesses on people's pics. I have looked at a few u/s on youtube trying to guess there too, and there is one video in particular that shows a baby with what looks like both a boy and a girl nub, just depending on the way the baby is moving and how the tech is viewing it (and they refer to the baby as a "he").

This a good link, Embryo Development external genital sex organs - angle of the dangle boy or girl ultrasound gender scan - Baby2see that helps explain early genital development.
From my understanding we all start off with genitalia that looks very much like boy parts. At 11 wks we all have that round bit on the end of the nub (genital tuber), which eventually devolops into the clitoris for girls, and the glans penis for boys, by 20wks.
The link also has a good diagram on the "angle of the dangle". At 14 weeks pregnant, you can clearly see that the genital tuber at the end of the nub is still very present, and the nub has risen by 30deg for boys, and has remained parrallel to the lower portion of spine for girls. Thus IMO, more weight should therefore be given to "angle of the dangle" rather than the shape. Having said that, in order to get an accurate nub shot, it all depends on fetal position, amount of amniotic fluid and thickness of abdominal wall. Thats why, some nub shots can be misleading. And obviously the closer the nub shot is to 14weeks, the greater the accuracy. Hope this helps?

I'll be honest, I don't look for angle shmangle at all, but from years of nub-guessing I have learnt that a nub that is "long, straight, and forked" is a girl nub. And a short, straight or angled, blob nub is a boy nub. The deciding factor for me is "long" or "short".

[Typical_Jules]

I look for angle first and foremost and the shape does come into play a bit as well
