Abstract
CONTEXT: Low T levels have been associated with ejaculatory dysfunction (EjD) in cross-sectional studies; however, the efficacy of T replacement in improving EjD has not been studied in a randomized controlled trial. OBJECTIVE: To evaluate the efficacy of T replacement in androgen-deficient men with EjD. DESIGN: A multicenter, double-blind, randomized, placebo-controlled, 16-week trial with T solution 2% versus placebo. SETTING: Medical centers in the United States, Canada, and Mexico. PATIENTS OR OTHER PARTICIPANTS: Seventy-six men with one or more EjD symptoms, including delayed ejaculation, anejaculation, reduced ejaculate volume, and/or reduced force of ejaculation, and two total T levels <300 ng/dL (<10.41 nmol/L) measured with liquid chromatography tandem mass spectrometry. INTERVENTIONS: Sixty milligrams of T solution 2% or placebo applied to the axillae for 16 weeks. MAIN OUTCOME MEASURES: The primary outcome was a change in the score of the three-item Male Sexual Health Questionnaire-Ejaculatory Dysfunction-Short Form (MSHQ-EjD-SF); secondary outcomes included measured ejaculate volume, scores of the bother/satisfaction item of the MSHQ-EjD-SF, the orgasmic function domain of the International Index of Erectile Function Questionnaire, and the sexual activity log. RESULTS: Seventy-six participants were randomized; 66 completed the study. Baseline demographic and clinical characteristics were comparable between the treatment arms. T replacement improved the MSHQ-EjD-SF score (mean score change, +3.1); however, this effect was not statistically different from placebo (mean score change, +2.5; P = .596). No differences were seen in any of the secondary outcomes or frequency of adverse events. CONCLUSION: T replacement was not associated with significant improvement in EjD in androgen-deficient men.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
