title: The effect of alcohol ingestion on hepatic aromatase activity and plasma steroid hormones in the rat.
abstract: Chronic alcohol ingestion in the rat resulted in increased hepatic aromatase activity, elevation of plasma estradiol, and a decrease in plasma testosterone levels. Testicular incubation studies indicated that the source of the estrogen was not of gonadal origin but was, most likely, due to increased peripheral conversion. The failure of HCG in vitro to restore testicular secretion of testosterone to normal levels suggested a direct action of alcohol, or a metabolic product, on gonadal secretory processes, as distinct from trophic hormone effects. This study demonstrates that many of the hormonal alterations seen in cirrhosis of the liver in man may be produced directly by alcohol feeding without cirrhotic changes in the rat.
