Otherwise we'll project unrelated biases under the guise of science. Otherwise we risk unconsciously ignoring or lessening the relevance of facts that contradict those biases.
There's nothing sexist about studying the differences between male and female and learning about the biological/physiological strength and weaknesses of each. But there's little scientific justification in extrapolating that to unrelated conclusions.
Edit: Not to mention the fact that we know very little about the brain compared to literally any other internal organ, so attempting to draw conclusions about behavior or sociology based on changes in the brain in some women during pregnancy is probably a fool's errand.
It isn't sexist to study sexual dimorphism. It would be sexist to have a conclusion about the sexes and then cherrypick evidence to support it- but finding evidence and then drawing a conclusion is in no way sexist.
