["The Australian Journal of Anthropology, EarlyView. ", "\nAbstract\nDrawing on fieldwork among the Akha people in Phongsaly District, Phongsaly Province, northern Laos, this paper examines Akha patrilineal kinship and its links to reproduction. The Akha people's reproductive decisions and behaviours are shaped by patrilineality, ancestral connections and cultural–spiritual perceptions of reproduction, which produce both continuity and contradiction in kin relations. Patrilineal kinship plays a crucial role in shaping reproduction by defining the number and gender of children, as well as assigning the duties and responsibilities of women and men. Reproduction is a means through which kinship is negotiated, defining women's values and contributions to sustaining patrilineage. However, far from being inferior, Akha women demonstrate agency by actively upholding patrilineal values. After relocation, Akha cultural practices concerning kinship and reproduction are subject to state policies and interventions aimed at integrating the Akha into national development. While the Akha informants expressed a willingness to change some cultural practices, such as the abandonment of infanticide, they were also firm in upholding the values of producing sons. This suggests that, despite their integration, Akha communities have negotiated to preserve their kinship, highlighting its continued centrality in guiding reproductive decision‐making and reinforcing social belonging in the post‐relocation context. In turn, reproduction remains fundamental to maintaining patrilineage, despite the alternative of adoption.\n"]
