Outcome Measures
Primary Outcomes (1)
Change in Arterial Stiffness
The primary outcome was the effect of 12 weeks testosterone replacement on arterial stiffness measured by ultrasound derived stiffness parameter β of the femoral artery. A reduction in ultrasound derived stiffness parameter β is clinically beneficial to patients and the study was looking for a reduction in this value. Stiffness index β was calculated from the diastolic carotid artery diameter (Dd), systolic carotid artery diameter (Ds), diastolic blood pressure (BPd) and systolic blood pressure (BPs) using the formula; Stiffness index β = (ln(Ps/Pd)) x Dd/(Ds-Dd). A full theoretical range of possible index scores does not exist.

- Ability to comply with all study requirements.
You may not qualify if:

- Current or previous prostate cancer.
- Raised prostate specific antigen (PSA) or abnormal per rectal examination unless prostate cancer excluded after specialist urology opinion.
- Severe symptoms of benign prostatic hypertrophy ('prostatism')
- Treatment with testosterone in the 3 months prior to the trial.
- Investigational drug treatment in the 3 months prior to the trial.

Limitations and Caveats
It was more difficult than anticipated to recruit patients to the trial and despite extension of the trial beyond expected completion date the target recruitment was not achieved.
