Scientific criteria for assessment of the reproductive toxicity of che
micals have been proposed by a Nordic group of experts and regulatory
representatives. The criteria take into account the results of clinica
l studies as well as of experimental research. The criteria should be
useful in, for example, product control and labeling and planning of a
safe work environment. The proposed Nordic criteria and examples of t
he assessment of the reproductive toxicity of some chemicals are prese
nted.
