Family planning needs: new opportunities, emergency contraception and other new technologies.
Modern contraception is considered to be one the major advances of the 20th century. Yet, as the next century begins, it is estimated that there is still a largely unmet need for contraception, with millions of couples worldwide who express a wish to limit the number of their children but do not use or are not satisfied with their contraceptive method. While the reasons are numerous, it is clear that there is a need for improved and new methods which are easier to use, under the user's control, with fewer side-effects and responding to the needs of different groups of users, including men. To respond to this need, current contraceptive research and development efforts focus on five main areas: emergency post-coital methods, user-controlled long-acting methods, dual protection methods against both pregnancy and sexually transmitted infections, methods for men, and methods with fewer side-effects including some that are more targeted to specific reproductive biological events. A number of leads are presented which are at various stages of development. Concluding remarks stress the numerous challenges of contraceptive development, not the least of which is the vision required of what the needs of future generations will be, since it takes 10-15 years to bring a new contraceptive to the market. More fundamentally, overall progress towards reducing the unmet need for contraception will depend on the status of women, specifically their decision-making power, and access to education and income.
