I've said more than once that there are minor differences in male and female brains, one of them being the part that enervates the penis, but discounting brain plasticity is pretty unscientific.
It's also pretty well established that any studies that claim innate differences in connectivity, white matter, etc., are all shoddy science done on tiny samples and with bias and or just plain stupid methodology. And there's never been any reputable science that demonstrates differing abilities.
"The supposedly larger female corpus callosum, a claim built on shaky foundations, is under no less serious dispute.18 This research has been thoroughly examined and critiqued by Brown University professor of biology Anne Fausto-Sterling who, in Sexing the Body, explains the challenges of establishing the size of a particular structure in the brain. And a meta-analysis conducted by Katherine Bishop and Douglas Wahlsten in 1997 concluded that “the widespread belief that women have a larger splenium than men and consequently think differently is untenable.”19 Summarizing this literature in a 2008 review, cognitive neuroscientist Mikkel Wallentin concluded that “the alleged sex-related corpus callosum size difference is a myth.” The culprit? Look no further than “the possibility of ‘discovering’ spurious differences when using small sample sizes,” says Wallentin.20

One particularly funny and telling study involved showed emotionally charged images to dead salmon.
"The researchers conclude not that this particular region of the brain is involved in postmortem piscine empathizing, but that the kind of statistical thresholds commonly used in neuroimaging studies (including Witelson’s emotion-matching study) are inadequate because they allow too many spurious results through the net."

If you truly want to understand the problems with these sorts of "studies" I highly recommend you read Fine's book. It will be a real education on how shoddy science that people want to believe in gets validated. She methodically takes apart ALL of this stuff. If you instead prefer to cling to your biases that come out of that shoddy science, there's not much I can do to change that.
