In September 2006, as a result of advocacy by international and national non-governmental organisations (NGOs), the United Nations (UN) General Assembly finally adopted the target of universal access to reproductive health. This health key issues guide explores issues relating to universal access to sexual and reproductive health (SRH) services using a rights-based approach. The guide examines factors that inhibit access to and use of SRH services, and discusses methods for removing barriers to care and improving access. Lack of access to SRH services and information contributes to high levels.
