so as to evaluate metabolism of catecholestrogens during pregnancy , changes in plasma unconjugated estradiol ( e2 ) , estrone ( e1 ) , 2-methoxyestradiol ( 2-me2 ) and 2-methoxyestrone ( 2-me1 ) concentrations were measured after a bolus injection of 40mg of estrone-sulfate ( e1-s ) or 100mg of dehydroepiandrosterone-sulfate ( dha-s ) to normal pregnant women near term .
