Steroids are important for sex differentiation in amphibian species Pleurodeles waltl. Besides, sex reversal can be induced by different factors, like the rearing temperature or exogenous steroids. This study has a double objective: to analyze effects of estrogen mimic chemicals and to characterize expression of estrogens and androgens receptors. The sex reversal in larvae of genotype male is induced by ethynylestradiol. This chemical is also more efficient than oestradiol. At the concentration, which could be found in the nature, the development of mullerian duct is induced. Thus, oviduct differentiation in male larvae could be a good marker of endocrine potentiql of estrogen mimic chemicals. The estrogen receptor alpha and androgen recept...
