Teachers' conflicts in implementing comprehensive sexuality education: a qualitative systematic review and meta-synthesis.

This qualitative systematic review and thematic meta-synthesis highlighted several conflicts among teachers in CSE implementation. Despite the teachers having a perception that sex education should be provided, traditional sex education has not yet transformed to CSE. The study findings also emphasize the need to identify the teacher's role in CSE implementation. The thematic meta-synthesis also strongly reflected the context of Christianity in Europe and Africa; thus, further research on the religious context in other regions is needed.
