Women remain underrepresented in research, and this lack of representativeness leads to bias in how healthcare systems and solutions are designed, measured, implemented and evaluated. Women-specific health conditions and those that disproportionately affect women remain under-researched, and a considerable funding gap persists. Addressing the research gap in women’s health may yield evidence to support more effective diagnostics, treatments and preventive strategies, ultimately improving outcomes and reducing costs for half the population.
