Andrew Huberman and obstetrician-gynecologist Dr. Thais Aliabadi discuss how PCOS and endometriosis-two leading causes of infertility-are massively underdiagnosed and frequently dismissed as "normal" women's issues. They explain diagnostic criteria, underlying biology such as hypothalamic-pituitary-ovarian axis disruption and insulin resistance, and treatment options including lifestyle, supplements, medications, and surgery. They also cover egg count testing, egg freezing, endometriosis pain management, perimenopause and menopause symptoms, breast cancer lifetime risk assessment, and the need for women to actively advocate for their own health within a flawed medical system.
