(340) The Association Between Varicocele and Premature Ejaculation: Systematic Review
Bibliographic record
Abstract
Abstract Introduction Premature ejaculation (PE) is one of the most common sexual disorders that negatively impacts couple’s satisfaction. Varicocele on the other hand is a highly prevalent condition affecting men population. A higher incidence of PE is observed among patients with varicocele, which incited several authors to evaluate the possible correlation between varicocele and PE. Others went beyond that to investigate whether varicocele repair can lead to an improvement in PE. Objective To systematically review the literature for all the studies exploring the relationship between PE and varicocele. Methods A systemic review was performed utilizing (PRISMA) statement. The PubMed, Google scholar and Scopus databases were used to look for articles published up to June 2023 using the appropriate keywords. Articles reporting an association between the presence of varicocele and PE and exploring changes in ejaculation latency time after varicocele correction were included. Data including study design, sample size, varicocele details, PE diagnostic method, outcome measured and tools used to measure it were collected. The Newcastle-Ottawa scale was used for assessing the quality of the included studies. Results A total of eight studies were identified, two of them were retrospective and six were prospective. Intravaginal ejaculation latency time (IELT) was used as a diagnostic tool for PE in 5 studies, Premature Ejaculation Diagnostic Tool (PEDT) in 1 study, Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) scores in 1 study, and subjective assessment in 2 studies. Two studies looked for the prevalence of PE among patients with and without varicocele. Both studies showed a significantly higher frequency of PE among varicocele patients. Whereas six studies evaluated the improvement in ejaculatory function after varicocelectomy; five of them revealed a statistically significant improvement. Quality check: only one study was of strong quality while the remaining 7 studies were of fair quality. Conclusions Limited evidence suggests the presence of positive relation between varicocele and PE. The small number of studies and patients, lack of enough prospective clinical trials, short term follow up, heterogenous study design and absence or diversity in the diagnostic tools used prevent our ability to build strong evidence. For the purpose of supporting the relation and validate it, further prospective studies on a larger number of patients with long-term follow up are needed to reach a solid verdict. Disclosure No.

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.
