Male skulls are more blockier and large compared to the female skull which are more round and delicate. The differences between the male and female skull develop during the maturity of the human, therefore not medically proven to be used on a developing baby. The ‘Skull theory’ seems to have originated online from many expectant parenting sites and discussions regarding baby gender and the skull differences between their boy and girl scan pictures. From this the trend has continued and many claim it has a high accuracy of 92%.
We advise this theory to be taken as entertainment only due to there being no medical evidence to support this theory for a baby gender prediction.
