THE ANDROGENIC ACTIVITY OF 11-KETOTESTOSTERONE: A STEROID IN SALMON PLASMA

Abstract
The androgenic activity of 11-ketotestosterone, which occurs at a high concentration in the plasma of postspawned male sockeye salmon, has been compared with that of testosterone propionate. The potency of 11-ketotestosterone was 58% as compared with standard testosterone propionate when a chick comb growth assay was employed.
