The Derogatis Interview for Sexual Functioning measures sexual desire.
The FACIT scale measures fatigue.
PANAS is a 20-item, self-reported measure of mood by 2 scales (positive and negative affect).
Delayed paragraph recall was measured with the Wechsler Memory Scale-Revised Logical Memory II test.
BVRT error scores were inverted so that higher scores reflect better performance for all cognitive outcomes, except Trail-Making Test A, B, and B − A wherein higher time in seconds reflects poorer performance.
The only significant difference between testosterone and placebo groups was Trail-Making Test B and Trail-Making Test B − A, wherein scores were better in the placebo than testosterone group for all men (P < .05).
Immediate paragraph recall was measured with the Wechsler Memory Scale-Revised Logical Memory I test.
