What is the nub theory?

Gender scan Bristol

What is the nub theory?

Some parents-to-be are desperate to find out the sex of their unborn baby as early as possible, and will search for clues at the very first scan. Which is pointless, isn’t it? Everyone knows you can’t tell the baby’s sex at the 12 week dating scan. Or can you?

The nub theory works on the basis that from 12 weeks, boys’ genitals (or the genital tuber, as they are not actually properly shaped bits and pieces at this stage, and both sexes will have a little tube) will be angled differently to a girls’, and so by carefully examining your scan picture, you can work out the sex.

If the nub is angled greater than a 30 degree angle in relation to the spine, it is likely a male fetus. If it is pointing straight out, under 30 degrees, or down, it is likely a female fetus!

How reliable is the theory?

There is no firm research to bear the nub theory out, but many mums swear it is accurate – and obviously as a bit of fun, it can do no harm!

So what do you think about the nub theory? Let us know your story in the comments section below.

If you are further along and want to try another gender reveal method this one is also popular and seems fairly accurate.
