Safety and Efficacy of Anastrozole for the Treatment of Pubertal Gynecomastia: A Randomized, Double-Blind, Placebo-Controlled Trial
Abstract
Pubertal gynecomastia is thought to result from transient imbalances between estrogen and androgen concentrations. Anastrozole (ARIMIDEX), a potent and selective aromatase inhibitor, decreases estrogen and increases testosterone concentrations in pubertal boys. The safety and efficacy of anastrozole for the treatment of pubertal gynecomastia were evaluated. In a randomized, double-blind, placebo-controlled study of 80 boys, aged 11-18 yr, with pubertal gynecomastia that had not reduced over a 3-month interval, subjects received either anastrozole (1 mg) or placebo once daily for 6 months. A response was defined as a 50% or greater reduction in the calculated volume of both breasts combined using ultrasonography measurements. A comparison of response rates was performed using logistic regression analysis. Secondary end points included changes in serum hormone concentrations. The percentage of patients with a response was 38.5% for the anastrozole group and 31.4% for the placebo group (odds ratio, 1.513; 95% confidence interval, 0.496-4.844; P = 0.47). At 6 months, the median percent change in the testosterone/estradiol ratio was 166% for the anastrozole group and 39% for the placebo group. Anastrozole treatment was well tolerated. In patients with pubertal gynecomastia, no significant difference in the percentage of patients with a 50% or greater reduction in total breast volume, as calculated from ultrasonography measurements, was demonstrated between the anastrozole and placebo groups.

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.
