Background: Post-sexual violence service utilization is often poor in humanitarian settings. Little is known about the service uptake barriers facing male survivors specifically. Methods: To gain insights into this knowledge gap, we undertook a qualitative exploratory study to better understand the barriers to service utilization among male survivors in three refugee-hosting countries. The study sites and populations included refugees who had travelled the central Mediterranean migration route through Libya living in Rome and Sicily, Italy; Rohingya refugees in Cox's Bazar, Bangladesh; and refugees from eastern Democratic Republic of the Congo, Somalia, and South Sudan residing in urban areas of Kenya. Methods included document review, 55 semi-structured focus group discussions with 310 refugees, semi-structured key informant interviews with 148 aid workers and human rights experts, and observation of service delivery points. Data were thematically analyzed using NVivo 12. Results: We identified eleven key barriers and situated them within a social ecological framework to describe impediments at the policy, community (inter-organizational), organizational, interpersonal, and individual levels. Barriers entailed: 1) restrictions to accessing legal protection, 2) legislative barriers such as the criminalization of same-sex sexual relations, 3) few designated entry points, 4) poor or nonexistent referral systems, 5) lack of community awareness-raising and engagement, 6) limited staff capacity, 7) negative provider attitudes and practices, 8) social stigma, 9) limited knowledge (at the individual level), 10) self-stigma, and 11) low formal helpseeking behaviors.
