Primary Outcome Measures:
  • Confirmation of time to reach steady-state when oral testosterone undecanoate is administered twice daily. [ Time Frame: One month ]

Enrollment: 15
Study Start Date: July 2009
Study Completion Date: January 2010
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Testosterone undecanoate
    Oral testosterone undecanoate, twice daily for one month.
Detailed Description:
Serum testosterone levels will be obtained in hypogonadal (serum testosterone <300 ng/dL) males receiving testosterone undecanoate capsules administered twice daily. Serum samples will be obtained consecutively in the morning on several days during one month of open-label treatment to confirm the time at which steady-state is reached.
