Brief Summary
Deficiency of testosterone, growth hormone, or both hormones can result in osteoporosis. If either hormone is replaced, the condition of the bones improves. The purpose of this study is to determine if dual hormone treatment for men deficient in testosterone and growth hormone improves bone structure more than testosterone treatment alone.

Outcome Measures
Primary Outcomes (1)
MicroMRI-derived Structural (Bone Volume Fraction-BVF) of the Distal Tibia at Baseline and After One and Two Years of Treatment.
Increased bone volume fraction (the fraction of bone that is bone, as opposed to the fraction that is marrow), as determined by magnetic resonance of the distal tibia
baseline, one year, two years
Other Outcomes (3)
Increased Trabecular Thickness, as Determined by Magnetic Resonance of the Distal Tibia
2 years
Improved Architectural Parameters of Trabecular Bone Reflecting Connectivity, as Determined by Magnetic Resonance Imaging
2 years
Increased Cortical Thickness and Cortical Density, as Determined by Peripheral Quantitative Computed Tomography of the Tibial Metaphysis
2 years

Eligibility Criteria
You may qualify if:
- Documented hypothalamic or pituitary hormone deficiency
- Testosterone deficiency, defined as total serum testosterone less than 250 ng/dL at two 8 AM readings
- Growth hormone deficiency, defined by either of the following:
- For subjects who have thyroxine and cortisol deficiencies, either a subnormal age-specific IGF-1 or a peak GH response to arginine-GHRH of less than 4.1 ng/mL
- For subjects who do not have thyroxine and cortisol deficiencies, either a subnormal age-specific IGF-1 or a peak GH response to arginine-GHRH of less than 4.1 ng/mL
- Duration of testosterone and growth hormone deficiencies of two years or more
- Replacement of cortisol and/or thyroxine deficiencies
- Able to give informed consent
You may not qualify if:
- Current testosterone treatment or treatment during the two years prior to study entry
- Current growth hormone treatment or treatment during the three years prior to study entry
- Use of other prescription or over-the-counter androgens (androstenedione, DHEA), estrogens, or antiandrogens (spironolactone, ketoconazole)
- Diseases that could influence bone, such as hyperparathyroidism
- Medications that could influence bone, such as anticonvulsants or glucocorticoids (prednisone greater than 20 mg/day for longer than 2 weeks/year). Calcium and over-the-counter vitamin D supplements are allowed.
- Cancer that could limit life expectancy to fewer than 5 years
- Neuromuscular disease or history of stroke with residual neurological defect
- Severe or uncontrolled psychiatric illness or dementia
- Noncancerous enlargement of the prostate gland (American Urological Association symptom score greater than 21)
- Prostate cancer by history, prostate nodule on digital rectal exam (DRE), or prostate specific antigen (PSA) greater than 4
- Current alcohol or drug dependence
- Heart failure (New York class III or IV)
- Unstable angina
- Myocardial infarction within 3 months of study entry
- Liver disease (ALT greater than 3 x normal)
- +8 more criteria
