Abstract
In this article I use literature from the medical and social sciences, as well as interviews with women and couples with fertility impairments, to argue against locating the compelling character of conceptive technology exclusively in pronatalist or patriarchal agendas. I suggest that the attraction to this technology derives not only from these broader cultural values but also from the way that the technology itself works (or does not work). Studying conceptive techniques helps illuminate why enough never seems to be enough for couples and physicians in pursuit of fertility.
