Testosterone and diabetes: 10-year clinical, real-life data from a registry
Professor Saad presents 2017 data from a registry that started 2004 in a urological practice. Most patients were obese and approximately one third had type 2 diabetes. Treatment with testosterone undecanoate for 10 years reduced HbA1c from 9% to 6%, while in the non-treated control group HbA1c rose from 7.8% to 10.6%. Fasting insulin dropped from 30 to 14 µU/mL in the testosterone treated men, while it rose from 26 to 37 µU/mL in the non-treated control group. HOMA-IR followed a similar pattern, in the testosterone treated men it dropped from 10 to 3.8, while in the non-treated group it increased from 7.5 to 17. Among testosterone treated men, 81% achieved the HbA1c target of 6.5% and 91% achieved the HbA1c target of 7.0%. Notably, after 10 years of testosterone treatment 12% of men in the testosterone treated group were in remission, meaning that they don’t need any of their previous diabetes medications to stay below HbA1c of 6.5%. None of the patients in the non-treated group achieved the HbA1c targets. Weight loss in the testosterone groups was 20.2%, while weight gain in the non-treated group was 4.6%. In the testosterone group, there were 8 deaths (5.6%) – none due to cardiovascular events – while in the non-treated group there were 41 deaths (24.1%). There was no major cardiovascular event in the testosterone treated group. In contrast, in the non-treated group there were 47 (27.6%) myocardial infarctions and 37 (21.8%) stroke events. Prostate cancer was also lower in the testosterone treated group, 7 patients (5%) vs. 17 (10%) patients in the non-treated group. These data clearly show that long-term testosterone therapy is critical for improvement of type 2 diabetes and achievement of health benefits.
