testosterone therapy improves mood and energy
In plain terms: Will testosterone therapy fix low mood and energy?
Part of: 💊 Testosterone therapy (TRT)
This is genuinely uncertain. The best large trials found only small-to-no effect on energy and vitality, and studies in men with actual clinical depression mostly found no antidepressant benefit beyond placebo. Some symptom scores improve modestly, but the 'T will restore your drive' promise outruns the evidence.

How the studies fall
What the evidence shows
TRT appears to give a small, inconsistent lift to mood and energy — a weak leaning-positive signal, not the transformation it's often sold as. The most rigorous large trials (the Testosterone Trials, TRAVERSE) found only small-to-null effects on vitality and fatigue, and randomized trials in men with diagnosed clinical depression generally found no antidepressant effect beyond placebo.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
