Men's and women's brains are remarkably similar, yet they also exhibit consistent distinctions that have significant effects on each sex.
In other words, brain sex differences specifically affect biochemical processes, may raise the risk of contracting particular diseases and may have an impact on particular behaviors. The biological variations must never be used as an excuse for prejudice or sexism. However, we think that a thorough comprehension of these variations can help researchers and doctors better address significant problems.
