Emergency contraception has been called the best-kept contraceptive se
cret. Previous research shows that several regimens of postcoital cont
raception offer safe and effective ways for women to avoid pregnancy.
Yet the methods are typically unavailable to women in developing count
ries. In this article, the authors review the main methods of emergenc
y contraception and describe experience with them to date. The prevale
nce and urgency of the need for making these methods available to wome
n in developing countries are assessed. The necessary elements for cre
ating such access are described. In several developing countries, cond
itions for introducing the methods may be more favorable than in indus
trialized countries. These advantages are reviewed. Finally, the autho
rs describe the challenges anticipated for broadening the availability
of postcoital methods in the developing world. They conclude with a b
rief series of recommendations for policymakers.
