Abstract
ABSTRACT An animal preparation has been developed which permits investigation of steroid secretion by the prostate of the dog. In this preparation the prostate is removed from the dog, placed in a metabolic chamber and infused with the animal's arterial blood via the prostatic arteries at a constant rate. This animal preparation secretes 5α-dihydrotestosterone into the prostatic venous blood. While testosterone is the most probable precursor for secreted 5α-dihydrotestosterone, data from experiments indicate that other steroids may serve as precursors for 5α-dihydrotestosterone in this animal preparation in vivo. The presence of »storage pools« and »secretory pools« for steroids in the infused canine prostate has been discussed.
