Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that increasing testosterone levels in men produces measurable cognitive effects?

Yes. Multiple studies demonstrate that altering testosterone levels in men produces measurable cognitive effects, particularly impacting domains like executive function, memory, and cognitive reflection.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved literature contains several clinical studies and meta-analyses showing that testosterone administration, replacement therapy, or natural variations in testosterone levels correlate with and cause measurable cognitive changes in men, particularly in executive function, memory, and decision-making tasks. While some studies note nuanced or null effects under specific conditions like severe energy deficit, multiple robust sources support the claim that testosterone has measurable cognitive effects.
