Experiences and problems associated with usage of prostaglandins in countries other than the United States.

The prostaglandins have entered into commercial use with few complaints of problems resulting from action of the drug. Disappointments in the results obtained from their use have stemmed mainly from a lack of understanding or a lack of appreciation of their limitations. Before full realization of their potential benefit as a tool to aid in breeding management is gained, considerable education of the veterinary profession, artificial insemination personnel, extension reproductive advisors, and animal owners must be accomplished.
