NCT00434824

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

Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects were at least 50 years of age
  • A body mass index (BMI) between 18 and 34 kg/m\^2
  • Symptoms of androgen deficiency (as indicated by a positive Androgen Deficiency in Aging Males (ADAM) questionnaire)
  • Calculated free testosterone measurement of \<0.26 nmol/L in the morning

You may not qualify if:

  • Clinical symptoms of obstructive benign prostate hyperplasia (International Prostate Symptom Score (IPSS) \>14)
  • Prostate specific antigen (PSA) level \> 4 ng/mL at screening
  • Cause of androgen deficiency other than aging, e.g. 'classical' diagnosis of primary or secondary hypogonadism
  • Hyperprolactinaemia or treatment with prolactin-lowering drugs
  • History of known chronic polycythemia and/or hematocrit \>50% at screening
  • History or presence of severe sleep apnea
  • 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
