  2. 18 and 75 years of age, inclusive.
  3. The subject is willing and able to read, understand the Subject Information Sheet and provide written informed consent.
  4. The subject has a body mass index (BMI) within 18-30 kg/m2.
  5. The subject is in otherwise good health as determined by medical history and physical examination.
  6. The subject is a non-smoker.
  7. The subject must agree to comply with the placement of an indwelling catheter on two separate occasions and the drawing of blood samples for the pharmacokinetic assessments.
  8. The subject is willing and able to comply with all testing and requirements defined in the protocol.
  9. The subject is willing and able to return to the study site for all visits.

Exclusion Criteria:

  1. The subject has any relevant deviations from normal in physical examination, electrocardiogram (ECG), or clinical laboratory tests, as evaluated by the investigator, particularly an elevated PSA reading >4.0 ng/ml or ALT and AST greater than 2 times the upper limit of normal, clinically significant anemia (hematocrit <35%) or renal dysfunction (creatinine >2mg/dL), active deep vein thrombosis, thromboembolic disorders or history of these conditions.

5. Study Description

Brief Summary
This study is a continuation of previous studies done in healthy volunteers to prove the efficacy of delivering Testosterone, the male hormone, rapidly across intact skin in s series of doses from low to high in men with low-to-no natural testosterone production to measure their response to the varying doses. The results of this study will inform further studies which will be longer in length, as to the starting doses. The study will be conducted in London, U.K. at the Advanced Therapies Centre, The London Clinic.
Detailed Description
48 Patients will be enrolled following 2 independent verifying blood tests of their diagnosis of Hypogonadism. there will be 4 cohorts of 12 subjects, each receiving doses of the trail materials, titrated by means of number of sprays applied. Doses will range from 10 to 70 mgs Testosterone.
