Molybdenum strongly inversely correlated to testosterone in men

Urinary molybdenum inversesly correlated to testosterone in nationally representative sample

Ram study: Molybdenum sulfate suppelementation reduces testosterone - perhaps due to creating a copper deficiency
- Molybdenum alone didn't seem to have much effect (but I'll need to see full text to confirm). Molybdenum sulfate did induce defficiency. Is it the sulfate???
