Physicians use prenatal genetic tests on pregnant women to gain an inc
reasing amount of information about fetuses before birth. These tests
do more than predict the future health of the developing fetuses, howe
ver; they transform the culture of motherhood-society's expectations o
f pregnant women and women's expectations of themselves. Decisions to
undergo genetic testing-and control or lack of control over disseminat
ion of the results of testing-affect women's self-image, personal rela
tionships, and how women are judged by institutions such as insurers a
nd employers. This article reviews psychological, anthropological, and
sociological research on the impacts of genetic testing and argues th
at healthcare providers and policymakers should consider these impacts
as they develop social policies for the use of prenatal testing.
