The Short Version
While cholesterol is a necessary biochemical precursor for testosterone synthesis inside cells, the claim that "higher cholesterol levels in the body" lead to higher testosterone production is not supported by human evidence. Multiple population-level studies (including NHANES data) find no association—or even an inverse relationship—between circulating cholesterol and testosterone levels. The rate-limiting step is intracellular cholesterol transport into mitochondria, not the amount of cholesterol in the bloodstream. Research also shows that low testosterone can itself raise circulating cholesterol, reversing the claimed causal direction.
