Actually the exposure to sex hormones in the womb cause quite a difference in brain structure. We can talk about how the corpus callosum (the white matter cable connecting the hemispheres) is much thicker in women, which is why our brains are much more homogeneous, and men's are more localized. We can talk about how a man’s amygdala, part of experiencing emotions and the recollection of such experiences, is bigger than a woman’s and works differently. On the other hand, a woman’s hippocampus, important to learning and memorization, is larger than a man’s. It ALSO works differently.
A lot of cross cultural studies have been done that have exposed certain sex related differences in behavior and cognition. Now, the tops of the two bell shaped curves are actually fairly close together, so it is practical to treat both sexes as equals, but when you go out to the extremes, there is where you will find significant differences between them. One example among many: women consistently do better on verbal scales such as reading and writing.

How men's and women's brains are different
I am aware of those reported differences from many sources but the overlap between the is so great that without knowing you were examining a male or female brain you would not be able to distinguish them. There is just too much similarity. And in terms of true functional differences we see huge overlap of abilities making it difficult to distinguish male of female performances without knowing whether they are male or female. Also the basic "wiring" and structures are the same. men and women have a hippocampus, men and women have an amygdala. Men and women have a corpus callosum. I have not seen a study comparing sized and weigh associated with any differences and whatever differences exist they are insignificant compared to the similarity.
