The advent of reversible long-acting contraceptives-IUDs, injectables
and implants-has provided women throughout the world with valuable new
fertility regulation options. These highly effective methods, togethe
r with male and female sterilization, have proven to be enormously pop
ular and are now used by the majority of women and men who are current
ly contracepting worldwide. Despite their remarkable popularity, long-
acting contraceptives have engendered considerable controversy. Politi
cal, ethical, and safety questions have emerged, stemming from the way
s in which these contraceptives have been developed and used over the
course of this century. At the heart of the concern is the issue of re
productive rights and freedom. This paper reviews the history of the d
evelopment of long-acting contraceptives, including the prospect of ne
w methods that will likely emerge from ongoing research and developmen
t. It also examines the history, in the United States and in developin
g countries, of the use and abuse of long-acting methods, including st
erilization, in the context of eugenics and population control policie
s. It then describes a new paradigm of reproductive health and rights
that has emerged from the International Conference on Population Devel
opment in Cairo, and which offers an enlightened approach to future po
licies and programs. In light of the wide variety of ways in which lon
g-acting contraceptives have been provided, the paper examines the rig
hts and responsibilities of governments, family planning providers, an
d individuals. An ethical framework for the use of long-acting methods
is discussed, and public policies for the future are proposed.
