Ultrasound Gender Prediction

The Nub Experts! Post your ultrasound images for our top experts in nub theory and potty shots


FAQ's and How To Post

How accurate is the gender prediction I will get in this forum?

ALL IMAGES POSTED BY A MEMEBER ARE THE PROPERTY OF THAT MEMBER AND BABYNUB ©️ THERE IS ABSOLUTELY NO COPYING OR DOWNLOADING IMAGES AS YOUR OWN FOR ANY USE WHAT SO EVER BEYOND THIS WEBSITE

*if* you provide a decent image.

Please keep in mind a still ultrasound image is much different than a live scan of baby, we are very experienced and compensate for this (as being a still image can sometimes be tricky!)

The image you have provided may not be appropriate for gender prediction, because of the quality or angle of the shot, or because of the week of pregnancy.

Nubs in the 11th week should only be taken as strictly guesses. Boys and girls start out looking the same up until the 12th week and just by our cumlative experience with nub guessing, the 11th week is just not reliable and has fooled a many of us seasoned guessers and experts!  So please just bear that in mind if you post an image when baby is measuring in this gestation.

Many people may respond with a gender prediction who do NOT have much experience with guessing and are just joining in with the fun. Which we encourage! But please know the moderators here have been early gender iding and guessing on nubs for many years. Even if someone says that your picture is "definitely" a boy or a girl, please remember this is not always a for sure thing. But I can say if a moderator says for sure, it is pretty for sure :)

What is a Nub?

Here is a quick link to a great site regarding the nub in very simple explained form:

Baby2See Gender External Nub

A nub is a small protuberance seen between the legs at as early as 9 weeks.  Both boys and girls start with a flat ambiguous nub (which is why most boys can be inaccurately guessed as girls during the 11th gestational week) It can be used to assess gender using the angle of the nub between the 12th and 14th week.  30 degrees and up=Boy, Under that=Girl. Sounds easy in theory, but this is used with a perfect mid line image of baby. Some nubs are tricky -they are angled in "the grey zone" where it can go either way. Gender guessing with the nub increases accuracy as you hit 13 wks, and is at its very lowest of accuracy in the 11th week. 

My Nub has a Fork?

A forked nub can be of either gender. Since ultrasound images in lines, especially anything round.

Is 3D or 4D better for assessing Gender?

No. And absolutely No. It adds lumps and bumps especially in early id'ing as baby has not much fat to them as yet.  A trained U/S will not attempt to id this early in 3D; only in 2D. If you have an elective scan and the tech says they can, please insist on 2D confirmation.

Can you get 3 Lines on a Boy?

Yes! Absolutely! If the tech takes the picture from too far back (ie behind the scrotum, near the bum), you can get 3 lines. Again, Many and most things will image as lines in ultrasound.

Potty Shots for Gender?

If you imagine yourself sitting inside a toilet and looking up. Someone comes and sits on the toilet, whilst you stare upwards. What do you see? Labia and on girls, and scrotum/penis for boys.

You can also identify and confirm gender in side profile shots well up until the 20th week as well.  If you have a tech that can confirm this way, please be rest assured the tech absolutely knows what they are doing!

One quick explanation to have a better understanding of this is to imagine a loaf of sliced bread.  Ultrasound images in planes. Each slice of bread is a "slice" of image. Also different image planes.

Most nub images will be in the sagittal plane putting baby into left and right parts as this is the plane used to measure the nuchal fold and CRL (crown to rump length)   A perfect mid-sag image will give a perfect image of the nub if baby is in a perfect supine position. 

In mid-sag, the loaf of bread would be sliced long ways

And always, information shared on this forum should not be taken as medical advice. Always only consult a trusted medical professional for any and all concerns.

HOW TO POST (You MUST read here before posting in this forum!)

This forum is for posting ultrasound gender images. 

Please read this as well as the FAQ announcement before posting here and please follow basic rules of the forum: Main rule #1! Just be nice to everyone. 

IMPORTANT: If possible, please try and remove any personal information from your images. 

Select Start a New Topic in the upper right to start your own thread  (you must be registered and logged in to post)

If you get an error saying an image is too large, you will need to resize it smaller. You can accomplish this in any paint program.  You can select resize image and usually putting it at 50% will make it workable.

PLEASE POST YOUR OWN THREAD. DO NOT POST PICTURES OF YOUR BABY IN SOMEONE ELSE'S THREAD FOR GUESSES. IT GETS WAY TOO CONFUSING. IF DONE, YOUR IMAGES AND RELATED POSTS WILL BE DELETED FROM THE ORIGINAL POSTERS THREAD. IT IS BETTER FOR EVERYONE TO REMEMBER: ONE BABY ONE THREAD (EXCEPTION, OF COURSE, IS ANYONE PREGNANT WITH MULTIPLES)

Please make sure to indicate the exact gestation of what baby was measuring at the time of the scan. This will guarantee more accuracy for nub guessing as the nub will differ greatly during the 12th week; believe it or not the days matter! Also, the same with any gender shots (profile and/or potty) it is just always better for members to know the gestation.

Also, you will automatically receive email notifications and site notifications on any new replies to your threads. You can also tag any member in a post simply by typing the @ followed by their site name.

Please know the forum can move fast some days, if you do not have a response to a question or new thread, you can bump your thread however much is needed to get it to the top so it easier to see.  Just post Bump!  Regular members as well as the moderators and admin are spread out all over the world, so consider time zone differences as well. 

Thank you!
