Subjects who have baseline severe urinary symptoms, as defined by AUA symptom score >19 (alpha-blocker medication allowed except if taking tamsulosin 0.8mg daily at baseline which indicates compensated severe symptoms and also can affect sexual function). 13. Subjects who have a history of significant psychiatric illness that would confound informed consent. 14. Severe, active co-morbidity, defined as follows: 1.
