Popis: The disposition of 4-14C dehydroepiandrosterone (D) and 7α-3H dehydroepiandrosterone sulfate (DS) (3H/14C =5.0) was studied in 11 subjects, 5 of whom had biliary fistulas. The mixture of D and DS was injected intravenously in 9 subjects and taken orally by 2 subjects. About 2% of 14C appeared in the bile, whereas 11% of 3H was excreted by that route. Urinary excretion in intact subjects was 45% of the 14C and 55% of the 3H. The total recovery of radioactivity was the same in all groups, indicating intestinal absorption of D and DS. This conclusion was confirmed by the results of oral ingestion, which closely resembled those following intravenous administration. The 3H/14C ratio of urinary testosterone glucosiduronide was initially 1/10 of that injected, suggesting that of the 2 steroids administered DS is a poorer precursor of testosterone.
