Norplant is a long-acting contraceptive that has been introduced into family planning programs all over the world. Its efficacy, safety and acceptability in the introductory phases have been widely tested, and most studies point to the need for good provider training in insertion and removal; good client counseling on side effects, suitable client selection to limit early removal, and attention to client access to removal services. Some problems with the method in the developed world, and a belief that it is too costly for developing countries, have led to a waning of support by international donors. Few studies have examined how service delivery expansion in the developing world can minimise and address potential problems as well as maintain Norplant's cost-effective edge against other methods. We examine the expansion of Norplant services in Kenya between 1992 and 1996, specifically in relation to client access to services, removal issues, and cost. Well-supervised and careful expansion has resulted in quality services being provided at more than 70 sites in the country. Early removal is limited, removals seem to have posed few problems, and Norplant offers a welcome and cost-effective addition to the family planning method mix.
