Primary Outcome Measures:

Percentage of oral TU treated patients with average serum testosterone (T)concentrations (Cavg) between 300 and 1000 ng/dL. [ Time Frame: Following 90 days of treatment ]

Secondary Outcome Measures:

Comparison of change from baseline in safety parameters between treatment groups. [ Time Frame: 365 days ]
- Number of subjects with adverse events during treatment of one year
- Change from baseline in safety laboratory parameters (i.e., clinical chemistry, hematology, cardiovascular biomarkers, PSA) for up to one year
- Change from baseline in prostate volume for up to one year
Percentage of treated patients with maximum serum T concentrations (Cmax) values that are (a) less than 1500 ng;dL, (b) between 1500 and 1800 ng/dl, (c) between 1800 and 2500 ng/dL, and (d) greater than 2500 ng/dL. [ Time Frame: 90 days ]

Study Completion Date:	September 2013
Primary Completion Date:	September 2013 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Oral testosterone undecanoate (TU)	Drug: oral testosterone undecanoate Starting dose: 200 mg T (as TU) BID. Doses may be titrated up to a maximum dose of 300 mg T (as TU) BID or down to a minimum dose of 100 mg T (as TU) BID based on serum T values collected at 4-6 hours post AM dose on Days 30 and 60.
Active Comparator: topical testosterone gel	Drug: topical testosterone gel 1% Starting dose: 5 g T applied once daily. Doses may be titrated up to a maximum dose of 10 g daily or down to a minimum dose of 2.5 g daily based on serum T values collected at 4-6 hours post AM dose on Days 30 and 60.

Eligibility


Ages Eligible for Study:	18 Years to 75 Years (Adult, Senior)
