Excerpt from Annual Report of Program Activities: National Institute of Child Health and Human Development, Fiscal Year 1979The program in contraceptive evaluation is concerned with the evaluation of the safety of various contraceptive methods which are currently in use, particularly with respect to long-term safety. Efforts are directed toward attaining improved safety of fertility regulation methods through identification of health risks associated with methods currently in use, delineation of particular circumstances which increase the risks of specific methods, and clarification of the mechanisms by which specific adverse effects of methods currently in use arise. The scope of the program includes the evaluation of health hazards associated with oral contraceptives and of intrauterine devices, and also the immediate and long - term risks associated with methods of sterilization for men and for women. In addition, studies are supported to ascertain the possible adverse consequences of pregnancy termination for the health of women, particularly regarding subsequent pregnancy performance. Among possible hazards or suspected health risks of steroid contraceptives being studied are cancer and other forms of tumors, heart disease, hypertension and thromboembolic disease, metabolic and nutritional disorders, birth defects, and also the understanding of the underlying mechanisms by which known complications arise.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
