When you first see your baby on an ultrasound, it’s an incredibly special moment. You might start wondering: Is it a boy or a girl? This curiosity leads many parents to explore early gender prediction methods like the nub theory, which suggests you can determine gender from the angle of the ‘nub’ (genital tubercle) seen on an early scan.
However, at The Original Window to the Womb, we know that nub theory is far from accurate. Here’s why you should be cautious – and why waiting until 15 weeks for a professional early gender scan with us is the best way to find out.
Why Nub Theory Isn’t Reliable – And Why You Should Wait Until 15 Weeks for a Gender Scan
Nub theory is based on the idea that the angle of the genital tubercle at 12-14 weeks can predict whether you’re having a boy or a girl. While it may seem convincing, the reality is:
- The nub can look similar in both boys and girls at this stage – It only begins to develop into either male or female genitalia after this point, making predictions unreliable.
- Baby’s position can affect visibility – If your baby is lying at an awkward angle, it can make the nub appear differently, leading to incorrect guesses.
- Scientific studies show mixed results – Some claim up to 80-90% accuracy, but this depends on perfect imaging conditions. In real-life scans, accuracy can drop significantly.
Simply put, nub theory is fun to guess with – but it’s not a medical or scientifically proven method. That’s why we only offer gender scans from 15 weeks onwards when we can confidently provide the most accurate result.
Why Choose a Gender Scan at 15 Weeks?
At 15 weeks, your baby’s gender is clearer and easier to identify on an ultrasound. Our highly trained HCPC-registered sonographers use advanced ultrasound technology to give you 99.9% accuracy – much more reliable than a guess based on the nub theory.
But a gender scan with us is about more than just finding out whether you’re having a boy or a girl. It’s an emotional bonding experience. Unlike early blood tests, which simply give you a result on paper, our scans let you see your baby moving, waving, and wriggling around on a big screen with your loved ones by your side.
Here’s why parents love our early gender scans:
