RESUMO
INTRODUCTION: The Acute Cystitis Symptom Score (ACSS) questionnaire first developed in Russian and Uzbek languages and now available in many other languages can be used for clinical diagnostics and patient-reported outcome (PRO) in female patients with acute uncomplicated cystitis (AUC). The aim of the current study was the linguistic validation and cognitive assessment of the French version of the ACSS questionnaire according to internationally accepted guidelines. METHODS: After two forward translations from Russian into the French language and backward translation into Russian and Uzbek, the two original languages, the scientific committee (SC) performed a slightly adapted French version, which finally was cognitively assessed by female subjects with different ages and educational levels and medical professionals, such as nurses, physicians, and pharmacists. RESULTS: All comments of the female subjects and professionals were discussed within the SC and after slight, but necessary adaptations, the SC agreed on the final study version of the French ACSS. CONCLUSION: Now, the linguistically validated and cognitively assessed French version of the ACSS can be used for clinical studies and practice.

PURPOSE: Since symptomatic, non-antibiotic therapy has become an alternative approach to treat acute cystitis (AC) in women, suitable patient-reported outcome measures (PROM) are urgently needed. The aim of this part II of a larger non-interventional, case-control study was the additional assessment of the ACSS as a suitable PROM. METHODS: Data from 134 female patients with diagnosed acute uncomplicated cystitis were included in the current analysis with (1) a summary score of "Typical" domain of 6 and more; (2) at least one follow-up evaluation after the baseline visit; (3) no missing values in the ACSS questionnaire data. Six different predefined thresholds based on the scoring of the ACSS items were evaluated to define "clinical cure", also considering the draft FDA and EMA guidelines. RESULTS: Of the six different thresholds tested, a summary score of the five typical symptoms of 5 and lower with no symptom more than 1 (mild), without visible blood in urine, with or without including QoL issues was favoured, which partially also could be adapted to the draft FDA and EMA guidelines. The overall patient's clinical assessment ("Dynamic" domain) alone was not sensitive enough for a suitable PROM. CONCLUSIONS: Scoring of the severity of symptoms is needed not only for diagnosis, but also for PROM to define "clinical cure" of any intervention, which could be combined with QoL issues. Results of the study demonstrated that the ACSS questionnaire has the potential to be used as a suitable PROM and should further be tested in prospective clinical studies.

STUDY QUESTION: Is the regionalization of epididymitis related to epididymal segmentation? SUMMARY ANSWER: We show for the first time that luminal ascent of bacteria is strictly gated by epididymal segment boundaries, involving ductal constriction adjacent to the infected area. WHAT IS KNOWN ALREADY: The epididymal duct is a continuous, unbranched tube, coiled into segments that are divided by connective tissue septa. Sonographic analysis indicates that swelling associated with epididymitis is predominant in the cauda region. Epididymal segmentation has never been investigated in the context of pathological alterations. STUDY DESIGN, SIZE, AND DURATION: We analyzed segment-specific changes in the epididymal duct in a mouse model and in men. In the mouse epididymitis model (3 days post-infection, injection of bacteria into the lumen of the vas deferens), two Escherichia coli strains were tested: a uropathogenic strain CFT073 (UPEC, n = 7) and a fecal non-pathogenic strain NPEC470 (NPEC, n = 5). Two control groups: phosphate-buffered saline, sham-treated animals (n = 4) and untreated mice (n = 8). In addition, segmentation was verified by ex vivo injection of dye into the interstitial spaces of untreated mouse epididymides. Histological findings were compared with specimens from epididymitis patients (n = 10, age range 14-78, median 60 years) who underwent surgical intervention; control: samples from patients without epididymitis (n = 16, age range 38-87, median 73 years). PARTICIPANTS/MATERIALS, SETTING, AND METHODS: We investigated the ascending infections by detailed histological analysis in correlation with local infection status in a mouse epididymitis model. As a proof of concept, rare patient material from two archives was analyzed: epididymides from patients who underwent surgical intervention for persisting epididymitis, and for control, histologically normal epididymides from men who underwent orchiectomy for therapy of prostatic carcinoma. MAIN RESULTS AND THE ROLE OF CHANCE: Luminal ascent of E. coli in mice was strictly gated by epididymal segment boundaries. In the mouse model, both strains of E. coli were detected exclusively in the distal cauda segment associated with damage of the epithelium and muscle layer. Ductal constriction occurred in the non-infected upstream segments of infected area, putatively blocking further luminal ascent of bacteria in UPEC-infected animals. Corresponding histological and morphological changes were found in epididymitis patients. The caput region was found to be unaffected in patients and the mouse model. LIMITATIONS, REASONS FOR CAUTION: Patient samples represented advanced cases of epididymitis that made surgical intervention necessary. WIDER IMPLICATIONS OF THE FINDINGS: Our data demonstrate the impact of epididymal segmentation, presumably a protective response mechanism against infectious invasion and bacterial ascent, during epididymitis and affirm the importance of rapid intervention. STUDY FUNDING/COMPETING INTERESTS: This work was supported by grants from the State of Hessen (LOEWE-MIBIE) and the DFG (KFO 181). The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: No clinical trial involved.

The objective of this study was to investigate spermatogenesis and testicular inflammation in a rat model of unilateral Escherichia coli epididymitis in a long-term follow-up. Unilateral epididymitis was induced in 30 Sprague-Dawley rats by injecting E. coli into the right ductus deferens. Oral antimicrobial treatment with sparfloxacin (50 mg kg(-1) body weight/7 days) was administered in half of the animals 24 h after infection. Five treated and five untreated rats were killed at 2 weeks, 3 months and 6 months after infection. Spermatogenesis was investigated using a histological semi-quantitative score. The presence of inflammatory cells (B- and T lymphocytes, macrophages and granulocytes) in the testicular tissues was evaluated by immunohistochemistry. The testes were sterile at all times. Over the course of 6 months, spermatogenesis underwent significant incremental impairment on the inoculated side as compared to the contralateral side (P < 0.001). However, overall spermatogenesis scores were not significantly different between treated and untreated animals (P > 0.3 at each time point). Finally, loss of testicular architecture on the inoculated side was not associated with any cellular inflammatory response. Thus, adjuvant therapies need to be studied, and research is necessary on how to prevent deterioration of testicular function in bacterial epididymitis.

As commonly used self-reported screening instruments for male hypogonadism demonstrated lack of specificity, a Hypogonadism Related Symptom Scale (HRS) was developed in 2009 as a novel self-rating screening tool. As the questionnaire has not been validated, the purpose of our study was to perform a validation in patients presenting with different disorders (e.g. infertility, HIV infection or metabolic syndrome) and disease-related risk to develop hypogonadism. Two hundred and eighteen patients aged 19-71 years (40.1 ± 9.5) who completed the HRS and other common questionnaires [International Index Of Erectile Function (IIEF), National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), Hospital Anxiety and Depression Scale (HADS), short form (SF)-12] were included. In all patients, blood levels of total testosterone, luteinizing hormone, follicle-stimulating hormone, oestradiol and sex hormone-binding globulin were determined and free testosterone was calculated. Cronbach's α for the scale was 0.896, split-half 0.871 for the 1st half and 0.807 for the 2nd half. Spearman-Brown coefficient was 0.767, and Guttman split-half coefficient was 0.759. Consistent correlations were found between HRS and IIEF5 (ρ = 0.57, P < 0.001), and HADS (ρ = -0.6, P < 0.001). In addition, HRS was significantly correlated with total testosterone (ρ = 0.135, P < 0.05), free testosterone (ρ = 0.148, P < 0.05) and oestradiol (ρ = -0.134, P < 0.05). Our validation study confirms the data from the initial development of the HRS questionnaire. Clinicians might have an additional advantage from the HRS when investigating males with suspected hypogonadism.

The Acute Cystitis Symptom Score - ACSS was originally developed in the Uzbek language and has demonstrated high reliability and validity. The study was aimed to develop a Russian version of the ACSS questionnaire and evaluate its psychometric properties. Translation and adaptation of the ACSS questionnaire containing 18 questions, 6 of them - for the typical symptoms of acute cystitis (AC), 4 - for the differential diagnosis; 3 - for the quality of life, and 5 - for the conditions that may affect the choice of treatment, were performed according to the recommendations developed by the Mapi Research Institute. Study involved 83 Russian-speaking women (mean age, 35.6 ±13.7 years); 38 (45.8%) patients were in the main group (patients with AC), and 45 (54.2%) - in the control group (without AC). Medical examination and appropriate treatment of the respondents were conducted in accordance with approved standards. After completing the course of therapy, 19 (50%) patients of the main group came for the control examination. There was statistically significant difference in the scores obtained in the two groups. Score profiles positively correlated with the results of laboratory tests (rho = 0.26-0.48). Cronbach's alpha for the Russian version of the questionnaire was 0.86 (95% CI, 0.81-0.91), area under the curve in the ROC analysis was 0.96. The results of testing the Russian version correspond to those of the original version. The Russian version of the ACSS questionnaire has high. reliability and validity, and can be recommended for clinical research and diagnosis of primary AC, and dynamic monitoring of the effectiveness of the treatment of the Russian-speaking population of patients.

BACKGROUND: Urogenital infections and inflammation may contribute significantly to ejaculate parameters essential for male infertility. METHODS: For this review, data were acquired by a systematic search of the medical literature of the last 5 years. RESULTS: We address the andrological relevance of male urogenital infections and inflammation on ejaculate parameters. The different classification systems of the WHO and NIH are illustrated. In most cases, a separation of the different areas of the urogenital tract, for example, of the prostate, epididymis and testicles, is not possible. The significance of bacteriospermia with common bacteria is discussed. Furthermore, HIV, ascending chlamydial, mycoplasmal and gonococcal infections are relevant. Especially, the relevance of sexually transmitted microorganisms seems to be underestimated. Leukocytospermia is not well defined in its biological significance. Seminal plasma elastase and the cytokine expression reveal better insights into the inflammatory response of the seminal pathways. Sperm antibodies and reactive oxygen species are not usable as indicators for infection and inflammation. Different aspects for an impairment of ejaculate quality have been demonstrated although a direct ascension of microorganisms to the prostate has not been confirmed. Probably, lesions of the epididymis may sustain an ongoing disturbance of sperm parameters. A potential negative influence of urogenital infections and inflammation on sperm function is under discussion. However, the severity of impairment differs according to the underlying infections and the involved compartments. CONCLUSIONS: Signs of infections and inflammation in the ejaculate of infertile men are common, and the relevance is often doubtful in spite of microbiological, spermatological and immunological facilities.

BACKGROUND: In adults, human papillomaviruses (HPV), lichen sclerosus et atrophicus (LSA) and phimosis are considered to be major risk factors for penile cancer. In boys, a possible association between phimosis, LSA and HPV has been suggested. OBJECTIVE: To investigate the role of HPV in the persistence of phimosis in children. PATIENTS AND METHODS: Out of a cohort of 420 boys presenting with foreskin problems, we prospectively sampled the preputial tissue of 82 patients during circumcision: 46 with steroid-naïve and 36 with steroid-resistant phimosis. All foreskins were assessed clinically and histopathologically with regard to appearance, inflammation, oedema, epithelial degeneration and fibrosis. The viral status of the foreskins was determined by immunohistochemistry and highly sensitive PCR, with subsequent subtyping by DNA hybridization (HPV types 6, 11, 16, 18, 31, 33, 35, 39, 42, 44, 45, 51-54, 56, 58, 59, 61, 62, 66-68, 70, 72, 73, 81-84, 90, 91). RESULTS: The foreskins appeared normal in 62 boys and suggestive of LSA in one single case. Small cracks or white scars were present in seven steroid-naïve and 12 steroid-resistant foreskins. LSA was diagnosed microscopically in two of the steroid-naïve and six of the steroid-pretreated group. No evidence of HPV was found in any of the juvenile foreskins. CONCLUSIONS: Our prospective study has provided evidence that HPV is not usually present in the foreskin of boys with persistent phimosis after their first year of life and that topical glucocorticoid treatment failure is not associated with HPV or any specific histopathological changes.

AIM: The prostatitis syndrome is a frequent disease affecting men in their reproductive age. The prostatitis syndrome is classified according to the National Institutes of Health (NIH) definition. Andrological implications of the prostatitis syndrome might encompass fertility issues, sexual dysfunctions and endocrinological alterations and influences. METHODS: A medline query using the terms prostatitis AND andrological implication, fertility, sexual dysfunction or endocrinology was performed. RESULTS: Acute bacterial prostatitis and andrological implications have not been adequately addressed. Patients with chronic bacterial prostatitis and chronic pelvic pain syndrome have been investigated evaluating sperm parameters. Some studies showed impaired sperm parameters. In chronic bacterial prostatitis, half of the patients reveal significant bacteriospermia with still debatable deleterious effects on sperm quality. Few interventional studies have addressed fertility issues in those patients. Anti-inflammatory treatment perhaps could have a positive impact on sperm parameters. Sexual dysfunction can be described by different components such as erectile, ejaculatory, orgasmic and sexual desire dysfunctions. Sexual dysfunction in chronic prostatitis adds to the number of positive symptom phenotypes and correlates therefore with increasing symptom scores in patients with chronic prostatitis syndromes. However, prospective interventional studies on the role of sexual dysfunctions are missing. Hormones have been found to modulate the inflammatory response via different receptors, particularly via estrogen receptor alpha. This evidence, however, is mainly limited to pre-clinical studies currently. CONCLUSION: Andrological implications are heterogenous and frequently described in patients with chronic prostatitis syndrome. Nonetheless, andrological factors have not been routinely addressed as primary variables in the different studies, which makes further research necessary.

PURPOSE: To obtain ultrasonography-based reference values for testicular volume, epididymal head size and peak systolic velocity (PSV) of the testicular artery in adult males of all ages. MATERIALS AND METHODS: Between 2009 and 2011, 306 Caucasian adult males (median age: 51 years; range: 18-88 years) without scrotal pathology underwent prospective scrotal ultrasonography. The testicular volume was calculated from the length (L), width (W), and height (H) using three formulas: a) 0.52 × L × W × H, b) 0.52 × L × W², and c) 0.71 × L × W × H. Thickness and height of the epididymal head and PSV of the testicular artery were measured. RESULTS: The median testicular volumes on the right (left) side were 13.9 (12.7) ml, 18.1 (16.5) ml, and 18.9 (17.3) ml for formula a), b), and c) respectively, and thus significantly different (p < 0.01 for all). The left testes were significantly smaller than the right testes (p < 0.01). The thickness and height of the right (left) epididymal head measured 7.5 (7.7) mm and 11.6 (11.3) mm, respectively. Median PSV of the right (left) testicular artery was 8.7 (8.6) cm/sec. No significant side-specific differences were documented with respect to epididymal size and PSV. CONCLUSION: It was possible to obtain virtually age-independent reference values for testicular volume, epididymal head size and PSV of the testicular artery in adults. With regard to testicular volumetry, it is essential to consider which formula has been used, since the calculated volumes differ significantly from formula to formula.

Prostate biopsy has been at the center of controversy in recent years due to high infection complications associated with the transrectal route and the withdrawal of authorization for fluoroquinolones and fosfomycin trometemol as prophylaxis. The Urological Infections Guideline Group of the European Association of Urology (EAU) recently published a meta-analysis in two parts based on randomized controlled trials (RCTs) and annually updates the data for the EAU guidelines. The meta-analyses show that transperineal prostate biopsy is associated with significantly fewer infectious complications than transrectal biopsy and should therefore be preferred. If transrectal biopsy is still used, then intrarectal cleansing with povidone-iodine and antibiotic prophylaxis should be used. Antibiotic prophylaxis strategies include targeted prophylaxis after sensitivity testing of the rectal flora, augmented prophylaxis with several antibiotics and empirical monoprophylaxis. Data from RCTs are available for aminoglycosides and third-generation cephalosporins.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is defined as chronic pain or discomfort in the pelvic region for at least 3 of the past 6 months. It is variably associated with lower urinary tract symptoms, psychosocial consequences, and sexual dysfunction. Specific test systems or biomarkers for a definitive diagnosis are still not available. The purposes of the basic diagnostic assessment are to determine the individual spectrum of symptoms and to rule out differential diagnoses of pelvic pain. Patient-reported outcome measures (PROMs) like the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) are valuable instruments for the initial diagnostic assessment and to evaluate treatment response. Classification systems like UPOINTS (urinary, psychosocial, organ specific, infection, neurologic/systemic, tenderness of skeletal muscles, sexual dysfunction) are valuable tools to determine the individual spectrum of symptoms, to guide the adapted diagnostic assessment, and to identify relevant targets for a multimodal and tailored treatment. Close urological monitoring of CP/CPPS patients is usually necessary, especially to minimize the unwarranted use of antibiotics in the case of undulating complaints.

BACKGROUND: Urogenital infections and inflammation are a significant etiologic factor in male infertility. METHODS: Data for this review were acquired by a systematic search of the medical literature. Relevant cross-references were also taken into account. RESULTS: We address infectious and inflammatory diseases of different compartments of the male genital tract and discuss their andrological sequelae. Chronic urethritis might be responsible for silent genital tract inflammation with negative impact on semen quality. In chronic pelvic pain syndrome, morphological abnormalities of spermatozoa and seminal plasma alterations are detectable. In the majority of men with epididymitis, a transient impairment of semen quality can be found during the acute infection. However, persistent detrimental effects are not uncommon, even after complete bacteriological cure. The relevance of chronic viral infections as an etiologic factor in male infertility is believed to be underestimated. Data concerning the impact of HIV infection on male fertility are of increasing interest as with the improvement in life expectancy, issues of sexuality and procreation gain importance. Moreover, effects of noninfectious systemic inflammation on the male reproductive tract have to be considered in patients with metabolic syndrome, a disorder of growing relevance worldwide. Finally, microbiological and related diagnostic findings in urine and semen samples are reviewed according to their relevance for male infertility. CONCLUSIONS: Available data provide sufficient evidence that in men with alterations of the ejaculate, urogenital infections and inflammation have to be considered.

PURPOSE: Investigating the diagnostic value of color Doppler ultrasound for defining the varicocele grade according to WHO criteria. METHODS: A total of 217 men (129 with clinical varicocele and 88 without clinical varicocele) were investigated by physical examination and color Doppler ultrasound and categorized according to WHO varicocele criteria (0, subclinical, I, II, and III). Diameter and reflux of the largest vein in the pampiniform plexus were measured bilaterally with the patient in the supine position in rest and during the Valsalva maneuver. To assess the possibility of differentiating varicocele grade by venous diameter, optimal cut-point values were determined by receiver-operator characteristic (ROC) analysis. RESULTS: With increased varicocele grade, a larger vein diameter was more significant in rest and during Valsalva (in all cases P < 0.05), except between grade I and grade II. Retrograde peak flow velocities were similar in every group (in all cases P > 0.1). Only grade III varicoceles demonstrated significantly increased peak flow values compared with all other grades (P < 0.001). There were no side-related differences when comparing identical varicocele grades (in all cases P > 0.1). Venous diameters above 2.45 mm in rest (sensitivity 84%, specificity 81%) or 2.95 mm during Valsalva (sensitivity 84%, specificity 84%) predicted the presence of a clinical varicocele. CONCLUSIONS: Our findings support the hypothesis that clinical varicoceles can be predicted with high accuracy based only on the diameter of testicular veins using cut-point values of >2.45 mm in rest or >2.95 mm during Valsalva maneuver in the supine position.

INTRODUCTION: The COVID (coronavirus disease 2019) pandemic has shown impressively that infectious diseases can have an enormous impact on the healthcare system and beyond. In the specialty of urology, patients present in daily practice with viral infections that are associated with numerous diseases. METHODOLOGY: The aim of this review is to describe viral infections relevant for urology, and in particular to emphasize vaccination prevention. A selective literature search was carried out on the subjects of "COVID and urology", "urogenital viral infections", "viral urological infections in transplant medicine", and "vaccination prevention of viral diseases". RESULTS: Coronaviruses have already caused two local epidemics: SARS (severe acute respiratory syndrome) epidemic and MERS (Middle East respiratory syndrome) epidemic. The fact that the SARS-CoV2 (SARS coronavirus 2) disease is contagious even without symptoms has essentially led to the rapid spread and global pandemic. A large number of viruses, which can also induce viremia, have been detected in the ejaculate and are thus associated with a possible urogenital infection. These include the mumps virus, Coxsackie viruses or enteroviruses, among others. It has also been shown that a Zika virus infection can also be sexually transmitted via the sperm as a carrier. Viruses therefore also play an important role in reproduction. When performing kidney transplants, urologists are often confronted with viral infections. The most effective weapon against viruses is prevention by vaccination. CONCLUSION: In terms of ethiopathogenesis, the genitourinary tract is most often affected by viruses, in the context of viremia or through reactivation due to immunosuppression. Immunomodulation and vaccination prophylaxis play a leading role in therapy.

BACKGROUND: Scrotal color Doppler ultrasound (CDUS) still suffers from lack of standardization. Hence, the European Academy of Andrology (EAA) has promoted a multicenter study to assess the CDUS characteristics of healthy fertile men (HFM) to obtain normative parameters. OBJECTIVES: To report and discuss the scrotal organs CDUS reference ranges and characteristics in HFM and their associations with clinical, seminal, and biochemical parameters. METHODS: A cohort of 248 HFM (35.3 ± 5.9years) was studied, evaluating, on the same day, clinical, biochemical, seminal, and scrotal CDUS following Standard Operating Procedures. RESULTS: The CDUS reference range and characteristics of the scrotal organs of HFM are reported here. CDUS showed a higher accuracy than physical examination in detecting scrotal abnormalities. Prader orchidometer (PO)- and US-measured testicular volume (TV) were closely related. The US-assessed TV with the ellipsoid formula showed the best correlation with the PO-TV. The mean TV of HFM was ~ 17 ml. The lowest reference limit for right and left testis was 12 and 11 ml, thresholds defining testicular hypotrophy. The highest reference limit for epididymal head, tail, and vas deferens was 12, 6, and 4.5 mm, respectively. Mean TV was associated positively with sperm concentration and total count and negatively with gonadotropins levels and pulse pressure. Subjects with testicular inhomogeneity or calcifications showed lower sperm vitality and concentration, respectively, than the rest of the sample. Sperm normal morphology and progressive motility were positively associated with epididymal head size/vascularization and vas deferens size, respectively. Increased epididymis and vas deferens sizes were associated with MAR test positivity. Decreased epididymal tail homogeneity/vascularization were positively associated with waistline, which was negatively associated with intratesticular vascularization. CDUS varicocele was detected in 37.2% of men and was not associated with seminal or hormonal parameters. Scrotal CDUS parameters were not associated with time to pregnancy, number of children, history of miscarriage. CONCLUSIONS: The present findings will help in better understanding male infertility pathophysiology, improving its management.

BACKGROUND: Infectious complications following prostate biopsy are increasing and fluoroquinolone prophylaxis has recently been suspended in Germany by the national authorities. OBJECTIVES: This review is intended to highlight current strategies for reducing infectious complications following prostate biopsy. MATERIALS AND METHODS: The European Association of Urology (EAU) guideline group on urological infections recently published a meta-analysis in two parts based on randomized controlled trials (RCTs). The most important contents shall be presented here. RESULTS: Transperineal prostate biopsy is associated with significantly reduced infectious complications than transrectal biopsy. If transrectal biopsy is performed, intrarectal cleaning with povidone-iodine and antibiotic prophylaxis without fluoroquinolones should be chosen. Antibiotic prophylactic strategies include targeted prophylaxis after susceptibility testing of the rectal flora, augmented prophylaxis with multiple antibiotics and empiric monoprophylaxis with nonfluoroquinolones. Here data from RCTs are available for aminoglycosides, third generation cephalosporines, and fosfomycin trometamol. CONCLUSIONS: The transperineal approach is preferred to reduce prostate biopsy-related infections. Fluoroquinolones are no longer approved for prophylaxis. Thus, alternative antibiotics based on local resistance, or targeted prophylaxis, in conjunction with povidone-iodine rectal preparation are recommended for transrectal prostate biopsy.

INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT) on the male accessory gland function are controversial. MATERIALS AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 groups according to their diagnosis: chronic prostatitis NIH type II (n = 38), chronic epididymitis (n = 12), and chronic urethritis (n = 21). RESULTS: The bacteriological analysis revealed 9 different types of microorganisms, considered to be the etiological agents, isolated in different secretions, including: urine, expressed prostatic secretions, semen and urethral smears: E. Coli (n = 20), Klebsiella (n = 2), Proteus spp. (n = 1), Enterococcus (n = 20), Staphylococcus spp. (n = 1), M. tuberculosis (n = 2), N. gonorrhea (n = 8), Chlamydia tr. (n = 16) and, Ureaplasma urealyticum (n = 1). The infection group had significantly (p < 0.05) lower: semen volume, alpha-glucosidase, fructose, and zinc in seminal plasma and, higher pH than the control group. None of these parameters was sufficiently accurate in the ROC analysis to discriminate between infected and non-infected men. CONCLUSION: Proven bacterial infections of the MRT impact negatively on all the accessory gland function parameters evaluated in semen, suggesting impairment of the secretory capacity of the epididymis, seminal vesicles and prostate. These findings were associated with an infectious related significant increase of semen pH. None of the semen parameters evaluated can be suggested as a diagnostic tool for infection.

Orchitis can be acutely symptomatic or chronically asymptomatic. Among the acute forms is the rarer isolated orchitis, which is of viral origin in most cases as well as the more frequent secondary orchitis, which is usually the result of an ascending bacterial epididymitis. In addition, sterile forms of orchitis are also seen in patients with systemic autoimmune comorbidities. Chronic asymptomatic orchitis is the term used to describe cellular immune infiltrates in the testes, which are observed in approximately 25% of cases of azoospermia during testicular biopsy. The etiopathogenesis of these infiltrates is largely unknown with postinfection and primary pathogen-independent autoimmune reactions being discussed. Animal experimental models of orchitis may be helpful to investigate the immunological mechanisms involved as well as the therapeutic possibilities.
