Abstract
BACKGROUND: Sex and gender are fundamental determinants of health, influencing disease risk, diagnosis, treatment, and outcomes across medical disciplines. While sex refers to biological characteristics, gender encompasses sociocultural dimensions, including behaviours and identities. RESULTS: The field of gender medicine has evolved significantly from its roots in the women's health movement of the 1960s and 1970s, which initially sought to address reproductive rights and the systematic exclusion of women from clinical research. Over time, the focus has expanded to recognize sex- and gender-based differences in all populations, including men and gender-diverse individuals. Despite progress, persistent challenges remain. Many clinical guidelines inadequately incorporate sex and gender considerations, and women continue to be underrepresented in clinical trials, resulting in suboptimal efficacy and a higher incidence of adverse effects in women. Recent initiatives, including government-funded research programs, specialized gender medicine professorships and regulatory measures promoting equitable clinical trial participation, represent positive steps forward. However, a systematic, interdisciplinary approach is required to fully integrate gender-sensitive medicine into research, education and clinical practice. This narrative review explores the historical development of gender medicine, current advancements and remaining challenges. We highlight the need for improved research methodologies, policy changes and targeted interventions to ensure equitable healthcare. A structured action plan emphasizing regulatory support, education, industry involvement and public awareness is essential to accelerate the field's integration. CONCLUSION: Recognising and addressing sex- and gender-sensitive health differences will lead to more personalised and effective medical care, ultimately improving health outcomes for all individuals.
