Brief Summary:

In this study we have evaluated the effects of three different doses of oral testosterone undecanoate in aging men presenting with a combination of symptoms suggestive of hypogonadism and low blood levels of the male hormone testosterone.

Specifically, we have studied the effects on:

  • symptoms suggestive of low testosterone levels
  • blood testosterone and other hormone levels
  • bone mass
  • muscle mass and fat mass
  • muscle strength
  • prostate
  • lipids, hematocrit

Condition or disease Intervention/treatment Phase

Criteria

Inclusion Criteria:

  • Unstable or untreated endocrine disorders
  • History or presence of clinically significant depression or other psychiatric disorder or any clinically relevant cardiovascular, cerebrovascular, endocrine, hepatic, renal or hematological disease, thromboembolism/thrombosis etc. which, in the opinion of the investigator, might compromise the subject's participation in the trial
  • Use of medication that would interfere with the efficacy and safety objectives of the trial
