The Claim
T3 and hCG exert steroidogenic effects on StAR expression in mouse Leydig cells that are similar in magnitude and additive, indicating that they regulate StAR through independent but complementary pathways.
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.
Two different hormones, T3 and hCG, both make a key protein (StAR) in mouse testicle cells work harder to produce steroids, and when you use both together, they boost it even more — like two different keys that each unlock the same door, and using both at once opens it wider.

The steroidogenic effects of T3 and hCG on StAR expression are similar in magnitude and additive, suggesting independent but complementary pathways regulate StAR in mouse Leydig cells.
What the research says
1 studyStudy: Molecular Mechanisms of Thyroid Hormone-stimulated Steroidogenesis in Mouse Leydig Tumor Cells
The study found that two hormones, T3 and hCG, both boost a key protein (StAR) in mouse testicle cells in similar ways, and when used together, they work even better — like two different keys unlocking the same door at the same time.
