The authors found that only a very small number of the brains studied had features that were entirely male, female, or intermediate between the two. The vast majority had a mosaic.

rains with features that are consistently at one end of the “maleness-femaleness” continuum are rare," the scientists wrote in the study. "Rather, most brains are comprised of unique “mosaics” of features, some more common in females compared with males, some more common in males compared with females, and some common in both females and males."
Lead author Daphna Joel hopes that the study will help do away with assumptions made about gender differences. “We separate girls and boys, men and women all the time,” she told New Scientist. “It’s wrong, not just politically, but scientifically – everyone is different.”
