Estimated Enrollment: 60
Study Start Date: April 1997
Study Completion Date: January 2007
Detailed Description:

A reliable form of androgen substitution therapy regarding kinetics, tolerance and restoration of androgenicity is paramount in hypogonadal men. Intramuscular injection of the long-acting ester testosterone undecanoate (TU) offers a new modality.

The objective is to assess safety of TU regarding metabolic and pharmacogenetic confounders in hypogonadal men treated with this new formulation.

This is a longitudinal prospective one-arm open intervention and observation trial. A minimum of 5 individual assessments is a prerequisite. Investigated modulators of safety parameters entering regression models are: nadir and/or delta total testosterone concentrations, body mass index (BMI), and age.

The setting Andrological outpatient department.
