title: The hormonal and ecological correlates of lactation infertility.
abstract: Some factors that may influence the results of studies of breastfeeding behavior in different cultures are identified. Findings of some of the demographic studies of rural areas in the so-called less developed nations are contrasted with studies in urbanized areas of such nations, as well as with studies from developed nations. A review of the physiology of lactation, specifically the role of prolactin is given along with some preliminary findings from the author's ongoing research in Australia.
