Urban Kenya has seen a growing population of adolescents who face significant reproductive health challenges. A systematic review was conducted using multiple databases (PubMed, Embase) to identify relevant studies published between and . Studies were assessed for quality based on predefined criteria. Gender-responsive programmes reported a significant improvement in contraceptive use among adolescent females by 50% compared to control groups. Findings suggest that gender-sensitive interventions can effectively enhance reproductive health outcomes in urban Kenyan adolescents when properly implemented. Programmes should be tailored to address specific needs and barriers identified within the study sample, with a focus on community engagement and continuous monitoring. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
