Outcome Measures
Primary Outcomes (1)
Gonadotropin Suppression
To quantify the gonadotropin suppressive activity of 4 weeks daily therapy of a combination transdermal gel containing 8.3 mg Nestorone® (NES) gel and 62.5 mg (1.62%) testosterone (T) gel, and of T gel (1.62%) alone. Specifically, the proportion (and 95% CI) of men who suppress both gonadotropins (luteinizing hormone \[LH\] and follicle-stimulating hormone \[FSH\]) to ≤ 1 IU/L in each group, will be quantified.
4 weeks
Secondary Outcomes (16)
Gonadotropin and Follicle-stimulating Hormone Suppression
