Came across this diagram for the skull theory for all of you who like to guess the gender on scan pics
"Skull Theory is an at-home technique for predicting gender, although fans claim it has a 92% accuracy rate. Basically, you compare your baby’s ultrasound profile picture to the diagram below, looking for certain ‘male’ or ‘female’ markers in the shape of the skull."
"skull theory" originated from forensics, which uses similar diagrams to identify the sex of human remains. Unfortunately, the changes in the skull that differentiate male from female do not take place until after puberty...so there is no way that the theory is accurate in utero. If you conduct a search, you will only find the theory mentioned on pregnancy message boards and a search on pub med turns up no scientific evidence that it works on infants/fetuses. Its just for fun. However, if you look up nub theory, which looks at the angle of the genital tubercle, it has been proven by medical journal publications to be over 90% accurate at determining the gender at 12 weeks.
This is all completely correct Skull theory is completely for fun, and something I came up with a few years ago after watching Time Team! (any Uk mums may know the programme lol) Even on my original post on the In-Gender site, maybe 2 years ago? it was said that it was for fun with no scientific back up, but it seemed to have spread like wild fire since then!!
BUT!! I reckon if you have the right picture with the right angle you still can have a good guess I have rarely seen a girl with a completely flat forehead, usually they do have a more semi circle from eyebrow to top of forehead and again I have only ever seen a strong slope from eyebrow to top of forehead on a boy, so maybe if your lucky it will work for you! if not theres always the cabbage gender test lol!!!!!
