Clinical practice guidelines for reproductive health care.

Amidst the rapidly changing landscape of diagnosis and management in reproductive medicine, it has become increasingly difficult to evaluate the usefulness of many clinical practices. Clinical practice guidelines are a way to incorporate the best evidence-based research with clinical experience, cost-effectiveness, and patient demands. However, there may be problems with the development, maintenance, and implementation of such guidelines. This series of papers describes existing guidelines in the American Society for Reproductive Medicine and internationally and provides clinician comments on how they should be used.
