Plasma testosterone concentration was determined at 8 am in 15 depressed men, ages 46 to 78, during illness and after recovery. There was no meaningful change for the group and in 11 cases illness and recovery values were essentially the same. Urinary testosterone excretion was also measured in seven of the men and there was no significant change for the group before and after recovery.
