The main sex education programme in Scotland is "Healthy Respect", which focuses not only on the biological aspects of reproduction but also on relationships and emotions. Education about contraception and sexually transmitted diseases are included in the programme as a way of encouraging good sexual health. In response to a refusal by Catholic schools to commit to the programme, however, a separate sex education programme has been developed for use in those schools. Funded by the Scottish Government, the programme "Called to Love" focuses on encouraging children to delay sex until marriage, and does not cover contraception, and as such is a form of abstinence-only sex education.
