Excretion of 19-nor-steroids from consumption of pork meat and offal:
ثبت نشده
چکیده
Extremely low levels of 19-norandrosterone can be naturally excreted in human urine. Sensitive methods being applied for the detection and identification of anabolic agents, the International Olympic Committee safely recommended in 1998, a threshold in males and females for reporting positive results. However, as it is the case with the other androgens, which could be endogenous in human, natural factors are systematically invoked to challenge the positive test results. The inadvertent intake of 1 9nortestosterone by eating contaminated meat of animals treated with growth promoters or from animals in which I 9-nortestosterone has been suspected to be endogenously formed, is a recurrent argument.

Some studies include poultry under the definition of meat, while others exc...
