The document discusses expanding contraceptive choice by supporting the development of modern and effective methods of natural family planning. Since 1965, USAID has supported research into natural methods and broadening the mix of methods to meet the needs of couples who prefer natural options. Natural family planning methods are based on sound biological principles and have been tested in scientifically recognized clinical trials. They provide an alternative for women who want to use natural methods for medical or personal reasons without requiring contraceptive supplies.
