The Garden of Fertility is a guide to using fertility awareness-that is, reading fertility signals in order to prevent or achieve pregnancy. Certified fertility educator Katie Singer explains how to observe and chart fertility cycles to determine when a woman is most fertile to increase chances of conception, or to exercise birth control naturally-a method that, when followed precisely, is as effective as the Pill. Unlike other books on fertility awareness, The Garden of Fertility also describes how to use the charts to gauge gynecological health and offers nonmedical options for strengthening reproductive wellness. This book provides all the information women never learned in sex education class, but should have.
