Ideologies of reproduction are social facts, collective representations, of the dramatic ways in which human beings construct and appropriate gender for the imaging of social reality. Such symbolic universes are often centered on the body (Foucault 1980;Martin 1989;Turner 1984;Douglas 1973). As a template of cultural signification, the body becomes a model through which the social order can be apprehended. For instance, gender hierarchies are sometimes envisioned by means of an anatomical or physiological paradigm (Needham 1973;Hugh-Jones 1979;Theweleit 1987). However, the operation of societal power is generally focused on women's bodies and bodily processes. Women, according to a widespread (and controversial) paradigm, are grounded in nature by virtue of the dictates of their bodies: menstruation, pregnancy, birth (Levi-Strauss 1966Ortner 1974;Ardener 1975;MacCormack and Strathern 1986).This conception of female sexuality and procreation as natural (that is, wild, untamed, raw, dangerous) seems at times to justify existing orders of power and domination. Textured in images of mastery over nature, cultural representations of gender stress the legitimacy of male authority (Bloch and Parry ). Men, as divine or sacred actors, establish symbolic monopoly over human reproductive processes by the simultaneous denigration and emulation of female sexuality. Blood is a focal metaphor in these imageries of power (Brain
