[In vivo and in vitro hydroxylation of testosterone and dihydrotestosterone in rats after liver damage and starvation (author's transl)].

The in vivo C-2-hydroxylation of testosterone and 5-dihydrotestosterone in rats was measured by labilisation of tritium as HTO after injection of [1 alpha, 2 alpha-T]testosterone or [1 alpha, 2 alpha-T]5 alpha-dihydrotestosterone (radiospirometry). After experimental liver damage caused by CCl4 or after starvation for 60 h the hydroxylation of the androgens decreased. Similar results were gained by measuring the C-2-hydroxylation of testosterone, 5 alpha-dihydrotestosterone and estradiol.
