Dr. Sarah Berga, a reproductive endocrinologist at the University of Utah, explores how hormones shape the brain and influence gender identity. Drawing from decades of research on neuroendocrinology and neurodiversity, she challenges the traditional binary model of male and female brains. Through studies on conditions like polycystic ovary syndrome (PCOS) and neuroimaging research, Dr. Berga highlights the complexity of brain development, the role of hormones, and the distinction between genetic sex and gender identity. This discussion provides critical insights for scientists, educators, and clinicians studying neurobiology, endocrinology, and gender diversity.
