An in vivo screening test for oestrogenicity was developed jointly by three laboratories by measuring vitellogenin in fathead minnows after up to 21 days exposure. This method will be further refined by determination of (anti-)androgens and aromatase inhibitors in the fish so as to widen the scope to other mode of action. This method will soon be validated with a further set of test compounds by Cefic/LRI-EMSG funded laboratories. The results of this ongoing work have been successful in helping the OECD in developing future fish test guidelines for assessing endocrine modulators.
