This book was an incredibly important read. So many believe that the brain functions identically in males and females which is utterly incorrect. Learning about the intricate nature of the female brain as it relates to hormones and the different stages of womanhood was extremely fascinating. I enjoyed the personal stories of patient interactions as they related to the content of the book. I look forward to reading more books on sex differences to further my understanding of the importance for analyzing topics from both the male and female point of view.
