Preconception care for men: a scoping review of knowledge, behaviours and interventions

AIM: This scoping review mapped quantitative evidence on men's preconception care (PCC) focusing on: (1) knowledge, (2) behaviours and attitudes, (3) reproductive intentions and (4) outcomes of educational or counselling interventions. The review also sought to identify evidence gaps and inform future policies and practices to enhance male engagement in reproductive health. METHODS: Quantitative studies involving men aged ≥18 years from high- and upper-middle-income countries were included. Studies focusing on couples, non-English-language publications, qualitative research, reviews and commentaries were excluded. Quantitative designs were prioritised to map measurable determinants and outcomes of engagement in PCC. Searches were conducted across seven databases in September 2025, following the PRISMA-ScR framework. No critical appraisal was performed, consistent with scoping review methodology. RESULTS: Fourteen studies (n=18 733 men) were included, most of which were observational. Findings indicated low fertility awareness, inconsistent engagement in preconception behaviours, and minimal use of supplements or healthcare services. Differences were noted by age, education and fatherhood status. One intervention improved knowledge but did not address systemic barriers. CONCLUSIONS: Men remain underrepresented in PCC. Gender-transformative, system-level reforms integrating men into primary care, health education and public messaging are needed. Future research should test context-specific, equity-oriented interventions to promote inclusive PCC for all.
