Summary

This trial will test if testosterone can improve the bone health of male veterans who have both low testosterone and diabetes.

Who is the study for?
This trial is for male veterans aged 35-65 with type 2 diabetes and low testosterone (T levels <300 ng/dl). They should have a BMI under 35, an A1C level below 10.5%, and be experiencing symptoms of hypogonadism. Men with severe prostate issues, certain blood conditions, or those on medications affecting bone metabolism are excluded.Check my eligibility
What is being tested?
The study tests if testosterone gel improves bone health in men who have both diabetes and low testosterone. Participants will either receive the testosterone gel or a placebo to compare effects on bone quality over time.See study design
What are the potential side effects?
Potential side effects of testosterone therapy may include skin reactions at the application site, mood swings, increased red blood cell count which can lead to complications like clotting disorders, and possible aggravation of sleep apnea.
