The Claim
In healthy older adults, a single oral dose of triiodothyronine (T3) is associated with a 13.8% increase in total testosterone and an 11.8% increase in sex hormone-binding globulin (SHBG) within 96 hours, suggesting that elevation of thyroid hormone levels may enhance androgen-related hormone production in aging men.
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.
Taking one pill of a thyroid hormone called T3 might cause older men to temporarily produce more testosterone and a related hormone, which could help explain why thyroid and sex hormones might be connected as men age.

What the research says
1 studyScientists gave older men a single pill of a thyroid hormone (T3) and found that their testosterone and SHBG levels went up by about 12-14% within four days — exactly what the claim said.
