Prior to the 1900s, this interest was somewhat episodic. Because of anxiety about infection, early attempts flourished only briefly and then were no more. In the twentieth century, however, as a result of renewed interest in intrauterine contraception, particularly in the developing countries, a number of individuals throughout the world began experiment­ ing with a variety of new intrauterine devices. Since then, a great number of these devices have been studied; a few have survived careful scrutiny, and IUDs now represent the second most commonly used form of medical contraception. It is estimated that approximately 15 million devices are in use at the present time, 3 to 4 million of them in the United States.
