In the last 25 years, Mongolia has made important strides towards establishing a favorable legal environment for providing youth- and adolescent- friendly sexual and reproductive health services. The current state of reproductive health services is a clear example of the failure of the government to ensure adequate management and coordination of various mechanisms and integrate services so as to improve their quality. The system of providing comprehensive sexuality education to adolescents is not fully functioning. This is readily seen from the fact that SRHR knowledge is low among youth and adolescents, adolescent fertility and birth rates are not declining, and STI prevalence rates are persistently high. The key goal of this monitoring research is to identify challenges and barriers in the implementation of policies to provide comprehensive sexuality education and reproductive health services to youth and adolescents.
