Criteria
Inclusion Criteria:

1. Overweight (BMI 25 to 42 kg/m2 inclusive) males age 18 to 60 inclusive

2. All clinical laboratory tests within normal ranges (any clinically significant
deviation of laboratory results will require approval of sponsor)

3. Previously or concurrently diagnosed as having secondary hypogonadism characterized as
having 2 consecutive morning testosterone assessments < 300ng/dL, one of which must be
confirmed at Baseline.

4. LH < 9.4 mIU/mL (at Visit 1 only)

5. Sperm count ≥ 15 million per milliliter (assessed twice at least 48 hours apart)

6. Ability to complete the study in compliance with the protocol

7. Ability to understand and provide written informed consent

8. Agreement to provide a total of up to 6 semen sample in a sponsor-approved clinic on
up to 6 separate occasions.

Exclusion Criteria:

1. Any prior use of testosterone treatments within the last 6 months

2. Use of spironolactone, cimetidine, Clomid, 5α-reductase inhibitors, hCG, androgen,
estrogen, anabolic steroid, DHEA, or herbal hormone products during the study

3. Use of Clomid in the past year

4. Uncontrolled hypertension or diabetes mellitus based on the Investigator's assessment
at baseline. Subjects treated for Type II diabetes will be allowed into the study.
Newly diagnosed diabetics need to be treated for at least 48 hours before being
enrolled in the study.

5. Clinically significant abnormal findings at Screening (Visit 1) or Baseline, based on
the Investigator's assessment

6. A hematocrit >54% or a hemoglobin >17 g/dL (sponsor may approve enrollment of subjects
with hemoglobin up to 17.5 g/dL if the subject is at a location with a high elevation)

7. Use of an investigational drug or product, or participation in a drug or medical
device research study within 30 days prior to receiving study medication.

8. Known hypersensitivity to Clomid

9. Symptomatic cataracts (nuclear sclerosis cataract or cortical cataract grade > 2 based
on 0-4 scale or any trace of posterior subcapsular cataract)

10. Abnormal fundoscopy exam such as central retinal vein occlusion

11. Any condition which in the opinion of the investigator would interfere with the
participant's ability to provide informed consent, comply with study instructions,
possibly confound interpretation of study results, or endanger the participant if he
took part in the study

12. Irreversibly infertile or compromised fertility (cryptorchism, Kallman Syndrome,
primary hypogonadism, vasectomy, or tumors of the pituitary)

13. Current or history of breast cancer

14. Current or history of prostate cancer or a suspicion of prostate disease unless ruled
out by prostate biopsy, or a PSA>3.6

upper limit of normal

22. History of myocardial infarction, unstable angina, symptomatic heart failure,
ventricular dysrhythmia or know history of QTc interval prolongation
