Abstract: | Biomedical research on a rare hermaphroditic condition among males of the rural Dominican Republic has supported biologically reductionist explanations of male gender identity development. I reinterpret this research by comparison to a parallel case among the Sambia of Papua New Guinea. Meanings of mistaken gender are reviewed to contrast sex assignment and socialization in two-sex and three-sex cultural systems. I refute the unicausal biological model and suggest that psychocultural factors in these cultures are more salient in the explanation of hermaphroditic sex-role change. |
