Using The Nub Theory, we can accurately predict the gender of your baby by assessing the infantile version of their genitalia. We can also confirm the gender after your gender scan, by looking at the genitals in what is commonly known as the potty shot. We will offer a full refund if there is no gender visible! Simply submit all of your scan images via the Submit Your Scan page and we will look at your baby’s developing genitalia. For the best chance of a prediction, submit ALL your images, the exact gestation and any other information that you think will be helpful.
