Many national and institutional family planning policies explicitly include fertility awareness-based methods among the method options that should be made available, but these methods are often not offered for a variety of reasons. After testing the efficacy of the Standard Days Method (SDM), which is a fertility awareness-based method that identifies Days 8–19 of the menstrual cycle as fertile for women with cycles lasting between 26 and 32 days, pilot studies were conducted to introduce it into programs. Through 14 pilot studies around the world, ministries of health, family planning associations and community development organizations introduced the SDM. Follow-up interviews with users and other data collection methodologies were used to track user characteristics and experiences. Supervision data and simulated clients assessed the effects on service delivery.
