Global Andrology Forum (GAF) Clinical Guidelines on the Management of Infertile Men with Varicocele
Bibliographic record
Abstract
PURPOSE: Varicocele is among the most common reversible causes of male infertility. Although varicocele is prevalent and there is a growing body of literature on the subject, there are still numerous debates surrounding the matter. This study presents Global Andrology Forum (GAF) clinical guidelines on the management of infertile men with varicocele. MATERIALS AND METHODS: A team of clinicians and reproductive experts reviewed contemporary evidence on all aspects of varicocele, including systematic reviews, meta-analyses, and the results of the GAF global survey of practices. They then formulated expert statements and recommendations, subject to a modified Delphi process until a consensus was reached. The final statements and recommendations were rated using the GRADE system. RESULTS: A total of 31 statements and recommendations on the evaluation and management of varicocele were introduced and scored by 24 experts. All experts agreed with the final statements. Varicocele is a significant contributor to male infertility. Its diagnosis is based mainly on physical examination, although imaging can be used in certain cases. Clinical varicocele associated with abnormal sperm parameters is the primary unanimous indication of varicocele repair. However, other indications can still be considered, and recommendations for a tailored approach to controversial situations have been presented. There is inadequate evidence on the use of medical therapy for varicocele. CONCLUSIONS: These clinical guidelines on the management of infertile men with varicocele, based on the GAF surveys, systematic reviews, and meta-analyses, point out the pivotal importance of varicocele in modern Andrology. Continued research is crucial to improving diagnostic accuracy and treatment outcomes, ultimately enhancing reproductive health for men with varicocele. Therefore, the current guidelines allow clinicians to develop effective management strategies for a common issue and address practical questions where evidence is lacking.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
