A little over 12 years ago I wrote a small volume entitled Infertility. It seemed to me at that time that significant advances in the field called for the publication of such a volume. The following is from the preface to that volume: During the past 15 years considerable progress has been made in the field of infertility diagnosis and management. It is perhaps a paradox that much of this increased knowledge has come about because of Western medicine's preoccupation with the search for a means to control reproduction. As a result, we have achieved new insights into the physiologic mechanisms involved in reproduction, and we have found better methods for measuring physiologic changes in reproductive health and disease. To these advances can be added improvements in the utilization of endoscopic and surgical techniques, in the diagnosis and treatment of infections and endometriosis, and in the treatment of hormonal disorders. During this period, too, through workshops and conferences and in journals and texts, these latest advances have been made available to physi­ cians, an outstanding example being the two volumes of Progress in Infer­ tility, edited by Drs. Jan Behrman and Robert Kistner. As necessary as these publications are, they do not offer an overall view of infertility diag­ nosis and management.
