Fertility Awareness-Based Methods for Family Planning: A Literature Review

A review of 23 research articles to examine fertility awareness-based methods revealed biologic indicators and tracking methods to identify the fertile window in reproductive-aged women. This literature review indicated that a woman's cycle regularity is a major determinant of which method is best. Additionally, the woman's desire to achieve a pregnancy and her preference regarding the intensity of training are factors in method choice. Some evidence suggests that use of at least two biologic indicators is most effective for determining the fertility window. Recommended web and mobile applications also are discussed.
