Research on sex in Ireland has been mainly confined to the study of sexual attitudes. The availability or lack of representative and detailed data has an impact on the policy response. The Irish Study of Sexual Health and Relationships (ISSHR) was designed to fill the need for data. This report is one of four that detail the findings of the study. This report provides a general overview of the main findings from the ISSHR Survey. ISSHR Sub-Report 1: ‘Learning About Sex and First Sexual Experiences’ provides more detailed findings on how individuals learn about sex and on their first sexual experiences. ISSHR Sub-Report 2: ‘Sexual Health Challenges and Related Service Provision’ provides more in-depth analyses of sexual health challenges such as STIs and crisis pregnancy as well as examining associated service use. ISSHR Sub-Report 3: ‘Contemporary Sexual Knowledge, Attitudes and Behaviours in Ireland’ provides a detailed examination of contemporary Irish sexual knowledge and attitudes, and the manner in which these are related to behaviours.
