In the United States, one of the primary ways that the feminist movement has worked to overcome gender bias has been through changes in the law and public policy. Technologies are "forms of legislation" (Winner 1977) that have not yet received the level of feminist attention they deserve. 1 As Winner observed, "Just as surely as. .. the laws and regulations of government, technological design is a place where some basic decisions are made about the identities and relationships, power and status, life chances and limits upon these chances" (2002, 1). Hence, it is important to work toward the achievement of feminist technologies (Layne, forthcoming). In this essay, I examine the home pregnancy test as a candidate for feminist technology. Home pregnancy tests have been promoted and greeted as libratory for women. They are relatively low cost and easy for women in the United States to obtain and use. In addition, they are noninvasive, pose no apparent health risks, and boast high levels of accuracy. In other words, they appear to be the very type of technology advocated by the women's health movement and by science and technology studies scholars who seek more democratic design and use of technoscience. Yet examination of ninety-two first-person accounts of use posted between 2003 and 2005 as part of a U.S. National Institutes of Health (NIH) project on the history of the test, accounts published on a pregnancy website, and the newsletters of two U.S. pregnancy loss support organizations spanning the period of 1981-2004 suggest that the presumed benefits of this technology are not so clear. 2 In fact, there are a number of hidden costs that come into relief when we examine how and by whom they are used. I conclude that home pregnancy tests do not offer women the benefits they purport to and, in fact, in some ways they disempower women by deskilling them, devaluing their self-knowledge, and enticing them to squander their buying power on frivolous consumer products. Despite all this, home pregnancy tests may be of value to some women in some circumstances, and thus, these information technologies should be improved to better serve women.
