The introduction of Cyclofem into national family planning programmes: experience from studies in Indonesia, Jamaica, Mexico, Thailand and Tunisia. Task Force on Research on Introduction and Transfer of Technologies for Fertility Regulation, Special Programme of Research, Development and Research Training in Human Reproduction, World Health Organization, Geneva, Switzerland.

Studies on the introduction of Cyclofem into family planning programmes have been undertaken in Indonesia, Jamaica, Mexico, Thailand and Tunisia. Cyclofem is a once-a-month injectable contraceptive containing 25mg medroxyprogesterone acetate and 5mg estradiol cypionate. A total of 7927 subjects were followed in close to routine service delivery conditions in primary and secondary family planning outlets. The studies confirmed the high efficacy of the method with 12-month pregnancy rates ranging from 0 to 0.7%. Major differences were seen in reasons and rates of discontinuation between countries, the overall 12-month life table discontinuation rates ranging from 33.5% in Indonesia to 71.8% in Tunisia. The reasons for discontinuation in each of the five countries are described, differences between countries contrasted, and service delivery issues which should be addressed further, raised.
