Nub theory - The most talked about theory across the internet, it really can help you find out if your baby is a boy or girl from just 12 weeks.
The nub theory is proven to be the most highly accurate form of early gender prediction, unlike most of the old wives tales – If examined by an expert, it can predict the sex of your unborn baby just by simply analyzing your 12 week scan photo.
Predicting your baby's gender as early as 12 weeks
Between 11 to 13 weeks in gestation, all babies have a nub between their legs called the genital tubercle, and according to the nub theory, the angle of the dangle will indicate whether its a boy or a girl. If the nub is over 30 degrees from the spine, its a boy - but if its under 30 degrees, its a girl.
All nubs will image as a fork. This fork is split into two parts. The bottom half also known as the urogenital folds will develop into the labia minora, and the top half will develop into the clitoris and will continue to retract into its final resting place in the weeks to come.
For male fetuses the genital tuber will develop into the glans of the penis,
the urogenital fold becomes the shaft and the labioscrotal fold matures into the scrotum.
DOES BLADDER POSITION HELP?
There is a lot of confusion around the bladder position and how this helps determine your baby's gender. The bladder is not any different in males or females.
The bladder should only be used as an anchor to measure the axis which helps determine if this is above or below 30 degrees.
THE NUB THEORY EXPLAINED
NUB THEORY CONFIRMED GIRL
Nub is parallel to the spine and below 30 degrees
NUB THEORY CONFIRMED BOY
Nub is above 30 degrees and showing full scrotum and penis in development
SO HOW ACCURATE IS THE NUB THEORY?
Nub Theory accuracy ranges......From 11 weeks in gestation the accuracy is around 70%. The reason for this is that all baby's will present with a nub that is parallel to the spine, this is because the nub is still in development and making rapid changes....
From 12-12.5 weeks there is a huge range in accuracy, between 80-98%, this is based on a whole lot of factors, such as the visibility of the nub, the position of the fetus, the thickness of the abdominal wall, image clarity and BMI. Drinking a pint of water before you have your ultrasound can help to get the baby moving and get a clearer picture for a nub theory prediction.
By having one of our experts analyse your scan images it will help you to understand the difference between the actual nub and what may be mistaken for cord, leg and sometimes foot.
When you make a purchase with us, we will check the visibility of your baby's nub, the angle in which it points too, the shape and overall look, we will also check for stacking or shadowing and the bladder position in which we use as an anchor. All factors mentioned above are taken into account when predicting your baby's gender, these factors are backed by science and with that proves the nub theory to be the most accurate way of determining gender from as early as 12 weeks.
However not all images will show a nub shot if this is the case, we will email and let you know, a full refund will be offered or we will offer the option of predicting through The Ramzi Theory
11 WEEK ULTRASOUND - NUB THEORY EXAMPLES
Below you will see 4 examples, these examples will show you why the nub theory is not accurate at exactly 11 weeks. Two of these nubs present very girly but were later confirmed by ultrasound to be boys, the other two nubs actually look slightly boyish in appearance and were later confirmed to be girls. The rapid changes between 10-12 weeks can lead to a lot of incorrect predictions.
APPERANCE OF THE GENITAL TUBERCLE
We often get asked, if a nub is showing as a fork it has to be a girl, is this right?
This information is actually incorrect. As you can see from our examples, we illustrate how a male nub is angled above 30 degrees, you can also see the tip of his nub points upwards indicating a baby boy. We also illustrate a female nub shot which is angled below 30 degrees, the nub points downwards and sits flush to her spine indicating a baby girl.
The length and shape of your baby's nub may sometimes indicate gender, but not always. For example, some say that a “forked” shape at the tip is indicative of a girl fetus, however we do not adopt this, as its clear that both sexes can be seen with a forked nub in the early stages of development. The reason you see a fork shaped nub in both female and male fetuses, is because this fork serves an important purpose. For females, this fork will become the labia and clitoris, for males, the top half of the fork will develop into the penis, and bottom fork into the scrotum.We also know a forked nub is a sign of an undeveloped nub or a late riser (in males)
The "stacked" nub as it's most commonly known consist of the developing penis and scrotal line. Both can be seen imaging in bright white at the base of baby's body. The penis is seen as a round shape, while scrotal line is located right underneath and longer in length this images as a short line (but not always)
Female nubs can sometimes image in funny ways too, this makes them appear as "stacked". This happens when the top part of the fork on baby's nub, also known as baby's clitoris has been captured at an off angle. These angles can often lead to much confusion and wrongful prediction of baby's sex in the nub theory community.
