The Claim
In men aged 42–99 years, higher thyroid stimulating hormone (TSH) levels are inversely associated with depressed mood as measured by the Beck Depression Inventory (BDI), with a statistically significant but small effect size (B = -0.36, p = 0.03), and this association is not observed in women and may be confounded by differential medication use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In men aged 42–99 years, higher levels of thyroid stimulating hormone are linked to lower scores on the Beck Depression Inventory, indicating less depressed mood, but this pattern does not occur in women and may be influenced by differences in medication use.

In older men, higher levels of TSH increase activity in brain regions that control mood by boosting the release of serotonin and norepinephrine, which reduces symptoms of depression. This effect does not happen in women, and medications can change how the brain responds to TSH.

In older men, slightly higher thyroid hormone levels were linked to slightly lower depression scores, just like the claim said — but this link wasn’t seen in women and might be influenced by medications.
