low plasma dehydroepiandrosterone sulfate ( dhea-s ) and androstenedione ( delta4 a ) concentrations , low urinary 17-ketosteroid and particularly low dehydroepiandrosterone ( dhea ) excretion and the minimal rise of plasma dhea-s and delta4 a and of urinary dhea in response to acth in conjunction with a normal response of other serum and urinary c-21 steroids are consistent with 17,20-desmolase deficiency .
