This scientific monograph provides a comprehensive summary of the clinical characteristics of Jadelle levonorgestrel (LNG) rod implants, as observed during clinical trials conducted by the Population Council. The monograph also reviews lessons learned about how to provide Jadelle, based partly on conclusions gleaned from the extensive experience with Norplant, the earlier implant system, and suggests practical ways in which to introduce Jadelle into family planning programs. The extensive question-and-answer section presents some of the scientific information in an easy- to- understand format that serves as a counseling tool. The section includes language from the Jadelle product labeling and also reflects the postmarketing, as well as clinical, experience with Norplant. In addition, the monograph summarizes new results from a fiveyear postmarketing study of Norplant in eight developing countries—information with direct relevance to Jadelle. Finally, a bibliography documents the extensive published research about contraceptive implants over more than four decades.

The monograph is written for health care professionals and policymakers interested in learning more about Jadelle as a possible addition to the contraceptives available in national family planning programs and in private practice.
