Enrollment: 180
Study Start Date: July 2012
Study Completion Date: May 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Testosterone gel (FE 999303)

Subjects received a starting dose of 46 mg (two actuations) of testosterone gel (2%) daily in the morning. The dose was further titrated (increased or decreased - three actuations [69 mg] or single actuation [23 mg], respectively) based on serum testosterone concentrations.

Testosterone gel was applied using an applicator, to the shoulder/upper arm in a contralateral fashion.

Drug: Testosterone gel (FE 999303)
