The exact process by which the fertilized mammalian ovum becomes implanted upon the uterine surface remains something of a mystery, and yet successful reproduction depends upon it. Two methods of contraception—the intrauterine device and the “morning-after pill”—are thought to be effective because they disrupt or prevent the process of implantation, but the biological basis of their effect is still imperfectly understood.

This book brings together authoritative accounts by leaders in the field of reproductive biology, researchers who have closely investigated implantation. The subject is approached from several angles: biochemical, endocrinological, pharmacological, anatomic, and immunological. A review of recent studies on implantation serves to put the individual reports in context. This book provides a needed perspective on an important area of reproduction research.
