Introduction

Abstract

In the 1960s, prompted by concern over the unprecedented rate of world population growth, particularly in the underprivileged, nonindustrialized countries of the Third World, physicians and scientists began to reevaluate the neglected subject of intrauterine contraception. Many obstetricians, and others, designed devices and proclaimed their virtures, sometimes without the benefit of substantiating data. Christopher Tietze entered this arena and proceeded to bring order out of chaos.
