This study evaluated the diagnostic value of the glucose/potassium ratio (GPR) and a combined model for distinguishing between TT, EO, and non-specific acute scrotal pain. This retrospective study included 373 patients, who were divided into three groups: TT (n = 103), EO (n = 120), and non-specific pain controls (n = 150). GPR and systemic inflammatory indices were calculated from admission blood samples. A combined model incorporating independent predictors (age, GPR, and white blood cell (WBC) count) was constructed using binary logistic regression. Diagnostic performance was assessed using a receiver operating characteristic (ROC) curve and multivariate logistic regression analysis.</p><p><strong>Results: </strong>The median GPR was highest in the TT group (23.6), followed by the EO group (21.0) and the control group (20.4) (p < 0.001). A GPR cut-off value of > 21.8 was associated with a 3.52-fold increased risk of testicular torsion (OR: 3.52, 95% CI: 1.97-6.25; p < 0.001). Although the GPR demonstrated the greatest accuracy among the individual markers (AUC: 0.738), the combined model produced superior diagnostic results, with an AUC of 0.839 (sensitivity: 75.6%; specificity: 81.5%; positive predictive value (PPV): 60.9%; negative predictive value (NPV): 89.7%). Multivariate analysis identified the following as independent predictors of testicular torsion: younger age (OR: 0.92); higher WBC count (OR: 1.30); and higher GPR levels (OR: 1.14).</p><p><strong>Conclusions: </strong>GPR appears to be a biomarker that could reflect specific metabolic stress in testicular ischaemia, which is distinct from the inflammatory response in EO. The combined model demonstrated the highest diagnostic accuracy in our cohort, suggesting its potential usefulness as an adjunctive triage tool. However, these findings are preliminary and require external validation in future prospective, multicentre studies before routine clinical implementation.</p>","PeriodicalId":8730,"journal":{"name":"Basic and Clinical Andrology","volume":"36 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13137708/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147832580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unique among arboviruses, ZIKV can be sexually transmitted, with viral RNA persisting in semen beyond the acute phase, posing potential risks to male fertility and assisted reproduction. This narrative review provides clinicians with a contemporary understanding of ZIKV epidemiology, virology, and its implications for male reproductive care.</p><p><strong>Results: </strong>ZIKV transmission has stabilised into low-level endemicity in Central and South America, with Europe reporting sporadic travel-associated cases. Persistence in semen is underpinned by infection of immune-privileged testicular tissues, including Sertoli, Leydig, and germ cells, enabling RNA detection for months post-infection even after systemic symptoms resolve. While replication-competent virus is rarely isolated beyond 4-6 weeks, viral RNA has been detected in semen over 180 days in rare cases. Clinically, ZIKV infection is associated with transient declines in sperm count, motility, and increased DNA fragmentation, likely mediated by inflammation, blood-testis barrier disruption, and impaired testosterone biosynthesis. Human studies suggest recovery of semen quality in most cases, but animal models demonstrate more persistent testicular damage and subfertility, supporting potential long-term reproductive impact. Current WHO guidance recommends a 3-month deferral from conception for men with confirmed or suspected ZIKV exposure. In assisted reproduction, cryopreserved semen from recently exposed individuals may retain viral RNA, requiring stringent handling and closed-system storage. Routine semen PCR testing is not widely adopted due to sensitivity limitations and inability to distinguish infectivity; thus, risk stratification based on travel and exposure history remains central to decision-making. In clinical practice, this risk stratification typically applies to men undergoing fertility assessment with recent travel to ZIKV-endemic regions, particularly in Central or South America, with compatible symptom history or recent onset infertility.</p><p><strong>Conclusions: </strong>ZIKV remains a relevant consideration in andrology and fertility practice, particularly in regions with ongoing endemic transmission and in individuals with travel-related exposure. Awareness of its virological properties, reproductive implications, and guidance for pre-conception counselling, laboratory practice, and semen storage is crucial. With appropriate precautions and patient education, most couples can safely proceed with fertility planning following ZIKV exposure.</p>","PeriodicalId":8730,"journal":{"name":"Basic and Clinical Andrology","volume":"36 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12977812/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147430648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
