Objectives:
     
     This review aimed to map and synthesize existing literature on sex and reproductive education policy implementation in primary and secondary schools in Asia and Africa.
   

Methods:
     
     Database searches yielded 24 relevant articles, which underwent thematic analysis.
   

Results:
     
     Most studies were conducted in Africa and looked at barriers to implementation. Studies assessing implementation showed it was incomprehensive. Barriers were: policy/curriculum issues, societal opinions, teaching discomfort, lack of educator training, and lack of sufficient economical support.
   

Conclusions:
     
     Based on the limited evidence, a cultural shift to reduce stigma seems necessary, alongside teacher and student involvement in policy formulation and implementation monitoring.
