Microtox toxicity screening test

For reproductive endpoints, it is envisaged that, as a first step and when available, information from repeat-dose studies (including screening reproductive toxicity studies, e.g. OECD TG 422 (32)), or short term endocrine disrupter screening assays, (e.g. Uterotrophic assay — test method B.54 (36); and Hershberger assay — test method B.55 (37)) is used to detect effects on reproductive organs for males and females.
