Is Testosteron useful for blood sugar?

The provided context does not contain information about testosterone's effect on blood sugar. In general, testosterone influences glucose metabolism: low levels are linked to insulin resistance, and supplementation in hypogonadal men may improve insulin sensitivity. However, evidence is mixed; some RCTs show benefit, others no effect. In women with PCOS, testosterone may worsen glycemic control. Without context-specific data, conclusions are limited. Testosterone testing or therapy should only be done under medical supervision due to risks (e.g., cardiovascular, prostate). Evidence: mechanistic/human-moderate (general), but not supported by given context. Safety note: Do not self-medicate; blood sugar management requires comprehensive evaluation.
