Study summary

The purpose of this study is to examine the effects of testosterone deficiency in men with diabetes on atherogenesis, inflammation, cardiovascular Risk factors And adiposity .

Read the detailed description

The purpose of this study is to examine the effects of testosterone deficiency in men with diabetes on atherogenesis, inflammation, cardiovascular Risk factors And adiposity . This will be done by comparing the changes in several body response indicators following treatment with testosterone in diabetic men with low testosterone levels and comparing them to diabetic men with low testosterone who are not treated with testosterone. These groups will also be compared with diabetic men who have normal testosterone levels

Inclusion criteria

  • Males with age 30-60 years inclusive.
  • PSA \< 2.6 ng/ml or \< 3.75 ng/ml with a negative prostate biopsy in the last 6 months.
  • IPSS ≤ 19. The lower age limit was decided on the fact that in our study on hypogonadotrophic hypogonadism in type 2 diabetic patients, the youngest subject was 31 years old. The upper age limit has been restricted to 60 to avoid including subjects with significant age-related declines in testosterone concentrations.Subjects on thiazolidinediones, statins, ACE inhibitors, angiotensin receptor blockers or antioxidants will be allowed as long as they are on stable doses of these compounds and the dosage in not changed during the study. Subjects on insulin, metformin or sulfonylureas can participate in the study, provided that minimal changes are made to the doses during the study

  • h/o prostate carcinoma;
  • Hepatic disease (transaminase > 3 times normal) or cirrhosis;
  • Renal impairment (serum creatinine > 1.5);
  • HIV or Hepatitis C positive status;
  • Participation in any other concurrent clinical trial;
  • Any other life-threatening, non-cardiac disease;
  • Use of over the counter health supplements which contain androgens;
