A new document on critical aspects for designing and conducting extended one-generation reproductive toxicity (EOGRT) studies under REACH is now available.

Experts from ECHA and Member States have found critical issues in the design and conduct of extended one-generation reproductive toxicity (EOGRT) studies. The issues can compromise data analysis and may raise questions over compliance or requests for further studies if there is a concern. ECHA encourages registrants and test laboratories to consider the issues and improve ongoing and future EOGRT studies accordingly.
