title: Contraception: a social revolution.
abstract: Modern contraceptive technology is more than a technical advance: it has brought about a true social revolution, the 'first reproductive revolution' in the history of mankind. This latter was followed in rapid succession by other major changes in human reproductive strategies. In the human species, sexual activity began to lose its exclusive reproductive meaning at an early stage of its evolution. Human beings must have practiced non-conceptive sex from the outset and therefore must have had a need to avoid, rather than to seek conception during intercourse from time immemorial. The search for methods to control fertility went on for millennia, but a valid solution was only found during the twentieth century, when the population explosion had forever changed the shape of humanity: in only one century the total population of the planet had grown from some 1.6 billion to more than 6 billion. That increase will remain unique in the history of Homo sapiens. At the global level, contraception provided a tool to deal with overpopulation and, in only 50 years, went a long way towards its resolution. However, to solve the problem, national and international family planning initiatives were required. For individuals, contraception also meant a revolution. It allowed sexual intercourse without reproduction. Only 25 years later, in vitro fertilisation permitted childbearing without sexual intercourse. Other advances followed and now cloning, that is, reproduction without the two gametes, looms on the horizon. Such a series of rapid, major changes in human reproductive strategies has confused many. For this reason, a constructive dialogue between sociology and biology is mandatory. Contraception is a powerful tool to promote equity between sexes; it improves women's status in the family and in the community. Avoiding pregnancy during the teens increases opportunities for a young woman's education, training and employment. By controlling their fertility, women get a chance to contribute economically to their household, which in turn may give them a greater share in decision-making. There are other specific areas in which contraception has produced beneficial social effects, first and foremost in reducing the need for induced abortion. It has also helped avoiding sexually-transmitted infections and is a very useful tool for educating youngsters to adopt more responsible sexual behaviors. Interventions in the field of family planning are among the most cost-effective health interventions.
