Improvement in sexual functioning and satisfaction in nonresponders to testosterone gel: clinical effectiveness in hypogonadal, HIV-positive males.

Impairment in gonadal function with reduced testosterone (T) levels is commonly associated with HIV infection and patients often complain of diminished libido and sexual dysfunction. The effectiveness of Testim 1% (Auxilium Pharmaceuticals, Inc., Norristown, Pennsylvania) topical T gel was evaluated in HIV-positive males who failed to experience satisfactory symptom relief following prior treatment with AndroGel 1% (Solvay Pharmaceuticals, Inc., Marietta, Georgia). In this open-label study, consecutive subjects were randomly assigned to experimental treatment with Testim 1% (5 g) or to maintenance therapy (control group) with AndroGel 1% (5 g). Twenty-four experimental subjects and 24 control subjects were followed for 4 weeks to evaluate improvements in sexual functioning and satisfaction. Changes from baseline in the 5 domains of the Brief Male Sexual Function Inventory (BMSFI) were compared between groups. The average percentage improvement favored the experimental treatment in all 5 comparisons of the BMSFI, including sexual drive (53% vs 18%, P < 0.001), erectile function (49% vs 7%, P < 0.004), ejaculatory function (15% vs 8%, P < 0.14), problem assessment (59% vs 12%, P < 0.003), and sexual satisfaction (58% vs 9%, P < 0.006). A greater percentage of subjects also reported satisfaction with the experimental treatment (85% vs 48%, P < 0.03), and these subjects were less likely to require upward dose titration at the final follow-up visit (30% vs 74%, P = 0.01). It is hypothesized that the results of the current study may be explained, in part, by an improved pharmacokinetic profile of the experimental intervention. Consideration of Testim 1% gel in HIV patients who have an inadequate response to prior T therapy is encouraged, although it is difficult to estimate the contribution of nonspecific study effects (eg, placebo) in this trial.
