“…Corroborating some [5,14], but not all studies [11][12][13], the data showed that temperature on days that patients presented with TT was not significantly lower than the mean atmospheric temperature in Fort Worth, Texas. Additionally, the mean atmospheric temperature did not differ by surgical outcome.…”

“…It has been suggested that, as the number of spermatic cord turns increases, blood flow to the affected testis decreases and time to inflict testicular vascular injury decreases [10]. Most controversially, some authors have found a higher number of TT during colder months [11][12][13], whereas others have not found this relationship [5,14].…”

“…[15][16][17] However, Cost et al 17 Brazil reported an increase in the occurrence of torsion during the winter, 18 but it included patients with testicular torsion presumed on admission, thus making it difficult to establish precise conclusions, because only 16% to 42% of boys with acute scrotal pain have surgically confirmed testicular torsion. [19][20][21] Hypothesizing that cold weather is the main initiating event for acute testicular torsion would be too simplistic.…”

CONTEXT AND OBJECTIVE: Testicular torsion is a medical and urological emergency because it can lead to loss of the organ. The theory of seasonal testicular torsion occurrence is based on studies from institutions located in cold and temperate regions. The objective here was to determine whether cold weather is associated with higher incidence of testicular torsion in a tropical country, such as Brazil. DESIGN AND SETTING: Retrospective study, conducted in a tertiary and teaching hospital. METHODS:Patients with acute testicular torsion confirmed by surgery between April 2006 and March 2011 were studied. Information on weather conditions at the time of symptom onset was collected. RESULTS: A total of 64 testicular torsion cases were identified. The months with the highest incidences of testicular torsion were June (16%), July (19%) and August (11%), which had the lowest mean temperatures, of 17.6 °C, 16.4 °C and 18.2 °C, respectively. Eleven percent of cases occurred during spring (October to December), 16% occurred in summer (January to March), 34% occurred in fall (April to June) and 39% occurred in winter (July to September). There was a significant association between the incidence of testicular torsion and the season (fall and winter), P < 0.001. CONCLUSIONS: Testicular torsion follows a seasonal association even in a tropical country, and is more frequent in the colder months of the year, namely fall and winter, when almost three-quarters of the cases occurred. These observations add further evidence that cold weather has an etiologic role in testicular torsion occurrence. RESUMO

“…In contrast, Grushevsky et al in USA, determined that testicular torsion occurrence were more likely in the winter compared with the summer [18]. This finding was similar to the two decades study of Korkes et al in Brazil [22]. It was also demonstrated that temperature and humidity correlated the risk of testicular torsion according to findings of Srinivasan et al [5].…”

Introduction: Testicular torsion is a surgical emergency which requires early diagnosis and prompt surgical management to avoid testicular damage. The aim of this study is to survey the clinical findings and outcome of the patients treated for testicular torsion in a university hospital in Babol, northern Iran. Methods: In this cross sectional study, a retrospective survey of all cases presenting with acute scrotum and primarily diagnosed as testicular torsion was conducted during 2001 and 2012 in Babol, northern Iran. All 103 cases were reviewed and several clinical data, including duration of symptoms and operative findings were collected. Findings: Of 103 patients who presented to the emergency department with acute scrotum, the median age of the cases was 16.0 years. Thirty four percent of the patients presented emergency unit less than 6 hours from symptom exposure. Pain (95.1%) was the major symptom in all patients. Surgery revealed that 72 (70.9%) cases were diagnosed firmly as testicular torsion that 23 patients underwent orchidectomy for a necrotic torsed testis. There were significant differences between orchiectomized versus non-orchiectomized torsion cases in affected side, symptom presentation to operation time. Conclusion: According to our results more than half of the cases presented more than in the golden time. Late presentation to hospital was the major cause of delay leading to orchidectomy in patients with testicular torsion. Greater effort in health education and direct or selfreferal to hospital may reduce this delay.
