Biological sex and gender have a tremendous impact on the efficacy and safety of pharmacological interventions in virtually every disease state. This book presents a comprehensive and up-to-date overview on how sex-specific information is guiding the diagnosis and treatment of diseases affecting men and women, as well as of disease states that disproportionally affects women. Experts in various fields discuss both preclinical and clinical research that is contributing to a better understanding of the impact of sex in the presentation, etiology, treatment, and disease outcomes. Also discussed are the challenges encountered in implementing this growing body of knowledge into practice, as well as possible avenues to recognize and reduce health disparities between men and women so that therapeutic interventions are tailored and improved.
