A randomized, placebo-controlled, double-blinded study on 40 men with type 2 DM.

Type 2 diabetes mellitus (T2DM) is a common endocrine disorder characterized by hyperinsulinaemia and insulin resistance.

Hypothesis Testosterone therapy increases lean body mass and insulin sensitivity in men with low normal levels of bioavailable testosterone and type 2 DM.

Type 2 Diabetes Mellitus Hypogonadism Drug: Testosterone Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Testosterone Therapy of Men With Type 2 Diabetes Mellitus (T2DM) - a Randomised, Doubleblinded and Placebocontrolled Trial of Men With Subnormal Testosterone Levels and T2DM.

Detailed Description:
Background Inadequate levels of androgens have been associated with an increased risk of chronic illnesses including obesity and diabetes. Moreover, testosterone treatment has been shown to increase lean body mass and lipid oxidation as well as insulin sensitivity in hypogonadal men.
