3. Meets the study definition of clinical hypogonadism, as evidenced by serum testosterone concentrations:

   1. Two serum testosterone concentrations < 300 ng/dL collected in the morning (between 0630 hours and 1000 hours local time) on at least 2 days separated by a minimum of 48 hours.
   2. Presence of at least 1 sign or symptom that may be related to low testosterone values and is/are consistent with hypogonadism

10. Prostate-specific antigen (PSA) > 3.0 ng/mL; men treated with 5-alpha reductase inhibitors (eg, dutasteride, finasteride) are eligible for participation as long as PSA levels are not > 1.5 ng/mL.

11. Body mass index > 50 kg/m2.

12. Sitting SBP < 80 mm Hg and > 150 mm Hg or sitting DBP < 50 mm Hg and > 100 mm Hg at any point during screening.

13. HbA1c > 11% at screening.

14. A current condition, therapy, laboratory abnormality, history of clinically significant medical or psychiatric conditions or other circumstance or reasons which, in the opinion of the investigator or the study staff, might pose a risk to the subject, make participation not in the subject's best interest, confound the results of the study (eg, if subject cannot comply with requirements of the study), make the subject an unsuitable candidate to receive study drug, or interfere with the subject's participation for the full duration of the study.
