Medical history has so far paid hardly any attention to the longue durée, a history in which, according to Braudel, 'all change is slow'. It is therefore one of the challenges of the emerging field of the social history of medicine to work audaciously across time as well as across space. An interesting subject, for example, is the history of contraception. Throughout history, there has been almost nothing people have worried about more than having sex without fear of consequence. At (...) first sight, the story of contraception seems to be one of progress, from the Ancient Egyptian crocodile-dung pessary to the modern-day condom and contraceptive pill. A closer look, however, shows a pattern of remarkable continuities in the reproductive behaviour of men and women over the last two thousand years. In this paper, I shall attempt to show why traditional male-dominated contraceptive methods still linger on despite the sexual revolution brought about by the invention of the 'pill' in the late 1950s.
