Amy Killen

Dr. Amy B. Killen, M.D., is a leading physician on a mission to empower women to take control of how they age. Through her focus on women's longevity, reproductive aging, hormones, and sexual health, she illuminates the physiology that has historically been understudied and misunderstood in women - making complex science not just accessible, but genuinely fun.
A board-certified former emergency physician, Dr. Killen has dedicated the past 13 years to health optimization and regenerative medicine. She specializes in evidence-based longevity interventions, integrating cutting-edge treatments such as stem cell therapy, body-identical hormones, and peptides with personalized lifestyle strategies and technology-driven decision-making.
Dr. Killen speaks on international stages about longevity, hormones, regenerative medicine, and what she calls "sexponential health," the surprising relationship between sexual wellness and healthspan.
A clinician, practice owner, online educator, and entrepreneur, Dr. Killen has founded several companies and clinics at the intersection of women's health, longevity, and technology, including Humanaut Health and the Human Optimization Project. Her approach challenges the male-dominated longevity field's one-size-fits-all thinking, advocating for pragmatic, personalized strategies that reflect how women actually live - and thrive.
She lives in Salt Lake City, Utah, with her family of five.
