Salvage Strategies for Nonresponders to Phosphodiesterase-5 Inhibitor Treatment for Erectile Dysfunction in the Aging Male
Bibliographic record
Abstract
This article reviews contemporary treatment strategies for the aging male who does not demonstrate a satisfactory response to first-line oral phosphodiesterase-5 inhibitor agents for erectile dysfunction. More than half of men aged 40–70 years are unable to attain or maintain a penile erection sufficient for satisfactory sexual performance, with the prevalence of erectile dysfunction climbing to more than 75% among those aged over 70 years. However, the aging male may fail to respond to or express dissatisfaction with oral on-demand treatment. Clinically effective phosphodiesterase-5 inhibitor salvage strategies include patient re-education, lifestyle changes, correction of risk factors, dose adjustment, agent switching, androgen replacement and/or psychosexual or relationship counseling. Important new data supporting the safe and efficacious use of daily phosphodiesterase-5 inhibitor dosing schedules are reviewed. If required, progression to second- and third-line treatments is appropriate for most men, and may include intracavernous penile injections, vacuum erection devices, multimodality therapy or implantation of a penile prosthesis.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
