Objective: We compared 12-month continuation rates, menstrual bleeding patterns and other aspects of acceptability between users of Cyclofem and users of Depo-Provera.

Methods: The life-table method was used to calculate quarterly continuation rates. In all, 360 Kenyan women were randomly assigned to one of the two contraceptives.
