Male child sexual abuse is over-represented in institutional settings. This realization has increasingly come into public focus in recent decades initially through lived experience, often with male survivors’ stories told in the media and subsequently through court cases and government inquiries. Beginning at the turn of the century with the Irish Commission to Inquire into Child Abuse (1999–2009), numerous national and state inquiries into institutional child abuse followed around the world. This scoping review asks the question: What is known from the research about the institutional child sexual abuse of males? Conducted in 2023 five databases were used (APA PsycINFO, CINAL, Medline, Scopus, Web of Science) producing 973 studies for screening. Applying the Arksey and O’Malley framework resulted in 29 studies meeting the inclusion criteria, which were analyzed. Of the 29 studies, 27 could be categorized into 3 broad areas of focus: survivor experience, impact, and disclosure. Two further studies considered: turning points and meaning making. The findings are discussed under the following headings: disclosure, impacts (emotional, mental health, alcohol, and other impacts), and what is helpful to victim/survivors. Implications for practice, policy, and research are examined along with limitations of the current research.
