Private cord blood banking is the practice of paying to save cord blood for potential future use. Informed by the literature on corporeal commodification and feminist theories, this article analyses women’s work in banking cord blood. This article is based on in-depth interviews with 13 women who banked in a private bank in Canada. From learning about cord blood banking to collecting cord blood and transporting it to the private bank’s laboratory, women labour to ensure that cord blood is successfully banked. Private cord blood banking involves the overlap or insertion of commercial practices, and relations with clinical practices and relations that may cause tensions and confusion for women and clinical practitioners. Moreover, private banking reinforces and is reinforced by an ‘intensive mothering’ ideology. This article shows that corporeal commodification is not confined to a laboratory and the work of experts but extends into women’s everyday lives.
