Recent social science commentary on the donation of body tissues and organs typically invokes Richard Titmuss's work on altruism and the gift relationship as a way of framing donative processes. Much of this discussion, however, has neglected to consider how altruism and body gifting is structured and promoted by organisations and institutions that make such processes possible. In this article I suggest that the accounts people give of their body gifting practices do not always fit orthodox notions of tissue donation as unconditional. Rather, people's perceptions of body gifting and donation depend very much on the kind of tissue being donated and who the tissue is being donated to. Given these complexities, we need more thoroughgoing discussion of the rituals associated with specific donation practices.
