Of the approximately 281 million international migrants and 35.3 million refugees around the world, almost half are women. These individuals experience significant stress due to language barriers, financial difficulties, poor living and working conditions, and discrimination. Consequently, concerns related to sexuality may receive lower priority despite their significant impact on overall well-being. This scoping review aims to review the sexual function of migrant and refugee women and identify any knowledge gaps in the field. We conducted a scoping review following the PRISMA-ScR guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews). We searched online databases-Medline, Embase, Emcare, PsycINFO, CINAHL, Scopus, Web of Science, and Cochrane-and gray literature, with no restrictions on year of publication, language, or study design. Utilizing Covidence software, 2 authors screened and extracted data from studies based on predetermined eligibility criteria. A thematic analysis was executed, and findings were reported descriptively. Initially, we identified 5615 studies; after screening titles, abstracts, and full texts, we ultimately included 12 studies. The review identified a limited body of research with various unvalidated tools. Moreover, these studies yielded heterogeneous results: migrant women reported less sexual knowledge, experience, and liberal attitudes, resulting in lower rates of desire and arousal as compared with nonmigrants. Some studies showed lower sexual function in migrants, while others found no significant differences between migrants and nonmigrants. The assimilation into Western cultures may influence migrants' sexual attitudes and behaviors. Factors such as education and gender role ideology can also significantly affect sexual function among migrant populations. This review underscores the limitations in previous sexual function research, emphasizing the need for a more inclusive approach. It also offers valuable insights for codesigning programs to address sexual dysfunction among migrant and refugee women, improving their well-being. Future research should prioritize neglected populations and create culturally sensitive interventions to reduce sexual health disparities in migrants.
