A silent shift is taking place in the world of ageing science—one that challenges long-held assumptions and spotlights a side of human biology that has long been overlooked. This story delves into a field where surprising discoveries are being made, long-standing gaps are being addressed, and a powerful new perspective is emerging. For decades, the science of ageing has mostly revolved around male bodies. Men dominated both the research labs and the headlines, often experimenting with extreme anti-ageing routines, from blood transfusions to VO2 max tracking. But quietly and powerfully, a new revolution is unfolding. And it begins with understanding the female body, not as an exception, but as the key to unlocking healthier, longer lives for everyone. What was once considered a niche subject, female biology in longevity research, is now being called “the canary in the coal mine” of ageing. And the ovary? It might be the most misunderstood organ in this story. The numbers don’t lie. Women, on average, outlive men by five years in almost every corner of the world…
