However, recent evidence suggests that retractility may predispose individuals to acquired cryptorchidism and complications such as torsion, testicular atrophy, and impaired fertility. This review aims to synthesize the current literature on the clinical features, natural history, complications, and management of retractile testes, and to evaluate whether conservative management remains appropriate. Methods: A structured narrative review was performed. PubMed (MEDLINE), Embase, Scopus, and the Cochrane Library were searched from database inception to 15 December 2025, and screening was reported using a PRISMA-style flow diagram. To our knowledge, this is the first review focusing exclusively on the retractile testis in the pediatric population, with a primary emphasis on management and treatment. Results: Prevalence among school-aged boys ranges from 1.2% to 3.9%. Reported progression rates to acquired cryptorchidism and orchiopexy vary widely, from 2% to 50%, with risk factors including inelastic spermatic cord, ipsilateral hernia, and younger age at presentation. Histological and sonographic studies demonstrate reduced testicular volume, seminiferous tubule degeneration, and impaired spermatogenesis, paralleling congenital cryptorchidism. Short-term complications include acute torsion, with abnormal gubernacular attachment and patent processus vaginalis frequently observed intraoperatively. Evidence for malignancy risk remains inconclusive. Conclusions: The available evidence, drawn largely from retrospective and observational studies, suggests possible associations between retractility and short- and long-term outcomes such as acute torsion, testicular atrophy, and impaired fertility, whereas an independent link with testicular malignancy remains unproven. This evidence is not yet sufficient to establish causation, and current professional-society guidelines continue to favor surveillance for the true retractile testis, reserving orchiopexy for documented ascent or other defined indications. Pending prospective data, these findings support structured, guideline-consistent follow-up, so that boys in whom ascent or atrophy develops are identified promptly.<\/jats:p>","DOI":"10.3390\/jcm15155846","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T09:47:41Z","timestamp":1785145661000},"page":"5846","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Retractile Testis in the Pediatric Population: Clinical Outcomes, Complications, and Management Implications"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2166-4338","authenticated-orcid":false,"given":"Maria","family":"Florou","sequence":"first","affiliation":[{"name":"Second Department of Pediatric Surgery, \u201cPapageorgiou\u201d General Hospital, Aristotle University of Thessaloniki, 564 29 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4435-3532","authenticated-orcid":false,"given":"Triantafyllia","family":"Koletsa","sequence":"additional","affiliation":[{"name":"Department of Pathology, School of Medicine, Aristotle University of Thessaloniki, 541 24 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-1703-6980","authenticated-orcid":false,"given":"Sophia","family":"Tsokkou","sequence":"additional","affiliation":[{"name":"Second Department of Pediatric Surgery, \u201cPapageorgiou\u201d General Hospital, Aristotle University of Thessaloniki, 564 29 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgia","family":"Raptou","sequence":"additional","affiliation":[{"name":"Department of Pathology, School of Medicine, Aristotle University of Thessaloniki, 541 24 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ioannis","family":"Spyridakis","sequence":"additional","affiliation":[{"name":"Second Department of Pediatric Surgery, \u201cPapageorgiou\u201d General Hospital, Aristotle University of Thessaloniki, 564 29 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0375-0005","authenticated-orcid":false,"given":"Christos","family":"Kaselas","sequence":"additional","affiliation":[{"name":"Second Department of Pediatric Surgery, \u201cPapageorgiou\u201d General Hospital, Aristotle University of Thessaloniki, 564 29 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1016\/j.jpurol.2011.03.016","article-title":"Retractile Testes: A Review of the Current Literature","volume":"8","author":"Keys","year":"2012","journal-title":"J.
