This article focuses on the systemic logics underlying the resurgence of the phenomenon of teenage pregnancy in urban areas despite the approaches deployed so far. The aim is to identify the structural causes of teenage pregnancies through an in-depth analysis of the socio-cultural system. More specifically, the socialization system of girls and boys is questioned to highlight the influence on the persistence of unplanned pregnancies in adolescence. The qualitative survey conducted in the cities of Sokodé, Kara and Dapaong, together with individual interviews and group discussions, confirms the hypothesis that the persistence of teenage pregnancies in schools is partly linked to the gendered education of girls and boys within the families of the communities studied. The results highlight that by enrolling the girl early in her role as a future mother and the boy in that of future father, the socio-educational system predisposes her to accept her destiny. As such, pregnancy is a preferred route, which is not always involuntary. Therefore, the fight against the resurgence of early pregnancies must take into account the reform of basic education as a whole to hope to significantly reduce the phenomenon.
