This short monograph was prepared in an effort to assist the Second International Conference on Voluntary Sterilization, February 25 - March 1, 1973, in Geneva. In view of the uncertain state of the world's laws on voluntary contraceptive sterilization, it is hoped that this monograph, by pointing out the facts of the situation as it exists, may lead to some improvement. The Conference provides an excellent opportunity to draw attention to the facts. It is also hoped that this collection of legislation will be of practical assistance to people working in this field of fast growing importance.
