The Claim
T3 stimulates testosterone production in primary cultures of adult mouse Leydig cells, thereby extending its steroidogenic effect beyond tumor cell lines to normal Leydig cell physiology.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A hormone called T3 makes normal mouse testicle cells produce more testosterone, which means it doesn’t just work in cancer cells—it also works in healthy ones.

What the research says
1 studyStudy: Molecular Mechanisms of Thyroid Hormone-stimulated Steroidogenesis in Mouse Leydig Tumor Cells
Scientists found that a thyroid hormone called T3 makes normal mouse testicle cells produce more testosterone, just like the claim says — and they proved it wasn’t just in cancer cells, but in healthy ones too.
