Eligibility Criteria:
Inclusion Criteria:
1. Subjects currently on stable testosterone replacement therapy for 3 months' duration using either the approved transdermal products Androgel® or Testim®, or injections of testosterone enanthate or cypionate with a morning serum testosterone concentration within the normal range (300 - 1000 ng/dl). These will dispensed either by prescription or for injections by the PI or co-PI in the office.
2. Total Serum PSA \>1.5 - 10 ng/mL
* If the total serum PSA is \>4ng/mL, the investigator, or a qualified urologist, will perform a 12-core prostate biopsy prior to entry unless such a biopsy has already been performed within the past 6 months.
* If the PSA rises above 4 during any time of the study, the patient will be referred to urology for biopsy.
* Patients with any suspicious rise in PSA of \>1.0 ng/ml/yr will have a repeat PSA performed within one month of the original value. If the rise in PSA remains \>1.0 ng/ml/yr, the patient will undergo a prostate biopsy.
* b. If the individual has had a negative biopsy more than 6 months previously, with documentation of stable PSA since that time, ie, no sustained increase \>1.0ng/ml.
3. Subject is able to read and comprehend the informed consent document.
4. If the subject is on current replacement therapy for hypopituitarism or other multiple endocrine abnormalities, the subject must be on stable doses of thyroid hormone and/or adrenal replacement hormones for at least 14 days prior to enrollment.
Exclusion Criteria:
1. Use of medications including those interactive with dutasteride from prior studies
2. Hematocrit greater than 51%
3. Prostate cancer in men found to have a prostate nodule on initial exam and subsequent positive biopsy
4. No prostate surgery within 2 months of entry
5. No prior use of finasteride, dutasteride within 6 months prior
6. A history of hepatic impairment or abnormal liver function tests (defined as ALT, AST, alkaline phosphatase or bilirubin \>1.5 times the upper limit of normal) with the exception that bilirubin elevations up to 2.0 times the upper limit of normal in the presence of normal liver enzymes will be permitted in patients with documented Gilbert's Disease. Subjects with Gilbert's disease not to be excluded.
7. No serum creatinine greater than 2.0 times upper limit of normal
8. No history of alcohol abuse with last 12 months
9. Has received any medication in a clinical trial within 2 months of enrollment
10. Use of anti-androgens, estrogens or coumadin
11. A history or evidence of newly discovered prostate cancer (e.g. positive biopsy or ultrasound, suspicious DRE). In patients with suspicious ultrasound or DRE, including patients with a focal nodule, biopsy shall be performed by a qualified urologist upon study entry unless one was performed and found to be negative within the preceding 6 months.
12. History of or current prostate or breast cancer
13. Baseline EKG with clinically significant abnormal rhythm or abnormal QT interval
14. Systolic blood pressure above 170mmHg or diastolic blood pressure above 90 mm Hg on baseline physical exam
15. Clinically significant peripheral edema on baseline physical exam
16. History of sleep apnea
17. History of psychiatric disorders or major depression
18. Consumption of grapefruit juice within 7 days of enrollment or is unwilling to eliminate use of grapefruit juice during the study period
