The Gender Gap in Longevity

Female Health, Male Health and Closing the Divide

Health systems have historically under‑served both women and men in different ways, from research gaps and underrepresentation in clinical trials to overlooked life stages such as menopause and andropause. This session explores how these biases shape health outcomes across the lifespan and considers what true “longevity equality” should look like in clinics, workplaces and policy, highlighting practical changes that can better support both sexes throughout longer, healthier lives.
