In men with type 2 or type 1 diabetes, lower testosterone levels (both total and calculated free testosterone) are independently associated with higher insulin resistance, and longitudinal changes in testosterone inversely correlate with changes in insulin sensitivity.

If you have diabetes and low testosterone, it is likely linked to your insulin resistance rather than just aging. Improving insulin sensitivity through weight loss and exercise may help normalize testosterone levels, though testosterone replacement therapy is not yet proven to be the primary solution.

Low testosterone levels were independently associated with insulin resistance in men with type 1 diabetes as well as type 2 diabetes. Serial measurements also revealed an inverse relationship between changes in testosterone levels and insulin resistance.
