Gender equality is a wide topic. Through the six major aspects of "Power, Decision-making, and Influence," "Employment, Economy, and Welfare," "Education, Media, and Culture," "Personal Safety and Justice," "Health, Medical Service, and Care," and "Environment, Energy, and Technology," we may understand the morphology and development of gender issues in the healthcare field. Healthcare facilities, like other facilities, are mainly dominated by men. Medical personnel are subject to gender-specific stereotype of occupation and gender role limitation, which restrict the personnel’s career development. Although regulations regarding gender equality awareness and education are provided in basic school education, training of medical personnel, and advanced education, the implementation effectiveness requires evaluation. Managers in healthcare fields shall adopt gender-related policies in terms of workplace interaction and physician–patient relationships. When health professionals provide health care, they shall identify the effect of the interaction between the patients’ physiological sex and social gender. Healthcare institutions are recommended to establish gender-friendly measures and relevant evaluation indicators to create gender-friendly healthcare environments. Gender issues in the healthcare field require efforts from all aspects and attention from the policy implementation agents and hospital managers.
