Designed for the general public, these three learning modules utilize text, illustrations, and exercises to describe various methods of birth control. The first module, "All about Contraception for the Teenage New Mother" by Rose Mary Pries, discusses the desirability of planned pregnancy and reviews the effectiveness and side effects of birth control pills, intrauterine devices, condoms, and foams. The second module, "Birth Control Pills" by Diann DeJong, describes how the pill prevents pregnancy, identifies the physical conditions which indicate that a woman should not take the pill, examines side effects, and discusses the menstrual changes to expect when taking the pill. The third module, "Functional Aspects of Vasectomy" by Louis G. Audette, details the physiology of the sperm transport and ejaculatory mechanism, explains the effects of a vasectomy on this mechanism, and refutes the popular beliefs that vasectomies are irreversible, result in castration, and cause hormonal imbalances. Each of the illustrated modules provides sequential reinforcement exercises with immediate feedback and concludes with a post-test and accompanying answer key. The length of time required to complete each module ranges from 15 to 20 minutes. (JP)
