Can low testosterone cause depression?

Short Answer

Low testosterone may contribute to mood changes in some men.

In Detail

Testosterone deficiency and depression share substantial symptom overlap — low energy, low motivation, anhedonia, irritability, and disrupted sleep. The relationship is bidirectional: low testosterone can produce depressive symptoms, and depression can lower testosterone.

In men with documented hypogonadism and depressive symptoms, testosterone optimization often produces meaningful mood improvement, sometimes within weeks. It is not a substitute for evaluation of true major depressive disorder, but it is a frequently missed contributor when men are placed on antidepressants without checking hormones first.

Our approach is to evaluate the whole picture — labs, sleep, life circumstances, and mental health history — and treat the contributors that show up. Testosterone therapy, mental health care, and lifestyle work are not mutually exclusive.
