Abstract
Prostate wts. were reduced by 50%, with marked histological degeneration, following adrenalectomy in immature castrated rats. The prostate degeneration was not prevented when adrenalec-tomized castrated rats were maintained with a body growth rate 93% of that of castrated controls by means of desoxycorticosterone acetate. The rat adrenal evidently is capable of secreting physiologically appreciable amts. of androgens during a certain phase in the development of the sexually immature animal.
