Abstract

PURPOSE: We determined the effect of testosterone solution 2% on total testosterone level and the 2 symptoms of hypogonadism, sex drive and energy level. MATERIALS AND METHODS: This was a randomized, multicenter, double-blind, placebo controlled, 16-week study to compare the effect of testosterone and placebo on the proportion of men with a testosterone level within the normal range (300 to 1,050 ng/dl) upon treatment completion. We also assessed the impact of testosterone on sex drive and energy level measured using SAID (Sexual Arousal, Interest and Drive scale) and HED (Hypogonadism Energy Diary), respectively. A total of 715 males 18 years old or older with total testosterone less than 300 ng/dl and at least 1 symptom of testosterone deficiency (decreased energy and/or decreased sexual drive) were randomized to 60 mg topical testosterone solution 2% or placebo once daily. RESULTS: Of study completers 73% in the testosterone vs 15% in the placebo group had a testosterone level within the normal range at study end point (p <0.001). Participants assigned to testosterone showed greater baseline to end point improvement in SAID scores (low sex drive subset p <0.001 vs placebo) and HED scores (low energy subset p = 0.02 vs placebo, not significant at prespecified p <0.01). No major adverse cardiovascular or venous thrombotic events were reported in the testosterone group. The incidence of increased hematocrit was higher with testosterone vs placebo (p = 0.04). CONCLUSIONS: Once daily testosterone solution 2% for 12 weeks was efficacious in restoring normal testosterone levels and improving sexual drive in hypogonadal men. Improvement was also seen in energy levels on HED though not at the prespecified p <0.01. No new safety signals were identified.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
