Although the technical feasibility of male contraceptives was demonstrated as early as the late 1970s, there is, to date, no male pill. Ever since the idea of hormonal contraceptives for men was introduced, scientists, feminists, journalists, and pharmaceutical entrepreneurs have questioned whether men and women would accept a new male contraceptive if one were available. Professor Nelly Oudshoorn, Professor of Technology Dynamics and Health Care at the University of Twente in the Netherlands, will explore these and other issues in a lecture to be followed by discussion.
