nub theory

If you are so eager to find out your future baby's gender that you can't wait until the 20 week scan, which clears up any doubts, you should look into the nub theory.

This is the concept used to describe an alternative way to predict your baby's gender at just 12 weeks pregnant (yes, you read it well!). Such a theory is based on checking the forming baby's genitals between the weeks 12 to 14 of your pregnancy. To do so, experts basically focus on the 'nub', the genital protuberance that both future boys and girls show in the scans at this stage of pregnancy, as their sexual organs aren't fully developed yet. 

Do you want to know how the baby nub theory works and how reliable it is? Or should you keep on biting your nails? Find the answers below!

 

How does the nub theory work? 

This theory works on the basis of 'the angle of the dangle' or, in other words, how the genital protrusion mentioned above looks like in the scan picture. Depending on how it's angled, it can help determine the foetus's sex or, at least, estimate it with high accuracy rates (according to its supporters).

The experts on the matter have come to the following conclusion regarding the nub theory: when the nub is sticking out upwards, at an angle of over 30 degrees in relation to the spine, the foetus is meant to be a boy. On the contrary, if the, let's call it, genital tubercle is pointing downwards, sticking out horizontally or upwards at an angle under 30 degrees to the spine, you will be a lot more likely to carry a girl, instead.

 

Is the nub theory reliable? 

Although many mums claim that the baby nub theory turned out to be accurate, helping them predict their baby's gender in advance, there's no scientific evidence to support it. However, the controversy goes on as there are studies that have proven a nub theory accuracy rate of 48%, at 11 weeks pregnant; 92%, at 12 weeks; and 94%, at 13 weeks.

 

On the eyes of the beholder

Leaving aside the controversy on whether it's reliable or not, what's clear is that not everybody is prepared to get an answer out of looking at scan pictures. Only 'experienced eyes' from veteran sonographers who have analysed thousands of such pictures could decide on a 'nub theory boy' or a 'nub theory girl' with decent outcomes. Also, let's not forget that first of all, your sonographer will have to take an optimum picture of the foetus inside the womb, because if he's turned away or kicking his legs, it may be impossible to tell.

If you don't want to wait to find out whether you are expecting a boy or a girl, you could look into clinics that advertise themselves as specialists in interpreting the foetus's sex based on scan pictures. Yet, be sure to leave some room for disappointment, as there's no guarantee of such predictions being correct.

 

What do you think? Do you rely on the nub theory or not? So far, only the 20 week scan is proven to give the ultimate answer about your baby's gender, and you shouldn't forget that. But, until you reach that point of your pregnancy, why not let yourself take some steps ahead on such an inquiry? As long as you are aware that the results may not be accurate and you put off any attempt to buy boy or girly clothes and items, guessing can be fun!
