<unk>  <unk>  is a field of research, healthcare, and social activism that explores the health of an individual's<unk>  system and sexual wellbeing during all stages of their life. The term can also be further defined more broadly within the framework of the World Health Organization's (WHO) definition of health―as "a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity"― to denote sexual wellbeing, encompassing the ability of an individual to have responsible, satisfying and safe sex and the freedom to decide if, when and how often to do so. UN agencies in particular define<unk>  as including both physical and psychological well-being vis-à-vis sexuality. A further interpretation includes access to sex education, access to safe, effective, affordable and acceptable methods of birth control, as well as access to appropriate health care services, as the ability of women to go safely through pregnancy and childbirth could provide couples with the best chance of having a healthy infant. Individuals face inequalities in<unk>  health services. Inequalities vary based on socioeconomic status, education level, age, ethnicity, religion, and resources available in their environment. Low income individuals may lack access to appropriate health services and/or knowledge of how to maintain<unk>  health.
