Abstract
The purpose of this symposium is to educate the scientists working in the various areas of research and regulation in developmental and reproductive toxicology regarding differences and commonalities in regulatory needs and concerns. Multiple agencies and professional societies are attempting to develop guidelines for performing safety evaluations that will allow single tests to meet the requirements of more than one agency in order to reduce animal usage and decrease testing costs. This presentation, and the two that follow, describe some of the problems addressed, the approaches used, and the current regulatory requirements of Japan and the U.S. EPA.
