Brief summary

Patients with diagnosed hypogonadism will be studied at baseline and then after 2 weeks of testosterone replacement initiation at usual therapeutic doses (10 g Testogel). The study will involve measurements of urea metabolism, and whole body protein breakdown and oxidation, and how much of the amino acids are being recycled for new protein synthesis.

Interventions

Participants are studied at baseline, and then after two weeks of transdermal testosterone (Testogel; Besins Healthcare Australia Pty Ltd, 10mg /g) administration on upper back/shoulders at a dose of 100 mg/day once daily in the morning. Adherence will be monitored by empty drug packet return.
