Abstract
Background The impact of Chlamydia trachomatis on semen quality has been studied with varied results. Aim To determine the prevalence of antichlamydial antibodies and their relationship with sperm quality among male partners of infertile couples in Enugu, South-East Nigeria. Materials and Methods It was a cross-sectional study of infertile male partners of couples attending infertility clinics at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, Nigeria. Their sera were assayed for antichlamydial antibodies, and semen analysis and culture were done for each participant. Results Two hundred and eighty-two (282) male partners of infertile couples were studied. Infertility was commoner among participants aged 40 years or more (45.1%) and was mainly of the "primary type" (62.1%). Antichlamydia antibody was detected in 156 (55.3%) participants and was significantly associated with sperm quality (P = 002; OR = 2.294; 95% CI = 1.36-3.88). Overall, 81 (28.7%) had abnormal sperm quality. The sperm count, progressive motility, and vitality were significantly lower in participants with abnormal sperm quality than those with normal sperm quality (P < 0.001) while morphology, volume, and liquefaction time did not differ significantly (P > 0.05). Staphylococcus aureus was the predominant organism isolated from culture (122/282, 43.3%) while Streptococcus species were the least (4/262, 1.4%). There was significantly more Staphylococcus aureus isolated from the semen of participants that were seropositive to antichlamydial antibodies than those that were seronegative (80/156, 51.3% vs. 42/126, 33.3%; OR = 2.105; 95% CI = 1.30-3.42; P = 0.003). Conclusion The prevalence of antichlamydial antibodies among male partners of infertile couples in Enugu, Nigeria is high and there is a significant association with sperm quality, sperm count, and bacterial isolates in seminal culture. Male partners of infertile couples in Enugu should be screened for antichlamydial antibodies and appropriate treatment offered wherever indicated. There is a need for increased public awareness and advocacy campaigns on the impact of Chlamydia infection on male factor infertility. This primary preventive measure may help in reducing the burden of Chlamydia infection and male factor infertility.

Abstract
Although it is well established that chlamydial disease renders female koalas infertile, there has been limited research on its effects on male koala fertility, specifically sperm quality. This study determined whether chlamydial infection adversely affects semen quality of naturally infected koalas and spermatozoa recovered from Chlamydia negative koalas co-incubated in vitro with C. pecorum elementary bodies (EBs). Semen from 102 south-east Queensland sexually mature wild koalas exhibiting varying degrees of chlamydiosis and clinical signs of disease were assessed for semen quality and compared to 11 clinically healthy, Chlamydia-free captive male koalas. For in vitro studies, semen samples were collected from 6 Chlamydia-free captive koalas, and co-incubated over 24 h with high and low concentrations of C. pecorum EBs and sperm quality assessed. Wild koalas displaying severe signs of clinical disease with C. pecorum present in the semen had significantly greater sperm DNA damage (P = 0.0267). The total % of morphologically abnormal spermatozoa was highest in wild koalas that had severe signs of clinical disease but whose semen was negative for C. pecorum (P = 0.0328). This apparent contradiction is possibly associated with wild males having resolved the infection but still possessing underlining reproductive pathology. A higher incidence of loose head spermatozoa occurred in semen of wild koalas not infected with C. pecorum compared to those that were C. pecorum infected (P = 0.026). In vitro incubation of semen with C. pecorum significantly decreased sperm motility and viability over 24 h.

Abstract
STUDY QUESTION Can Chlamydia be found in the testes of infertile men? SUMMARY ANSWER Chlamydia can be found in 16.7% of fresh testicular biopsies and 45.3% of fixed testicular biopsies taken from a selection of infertile men. WHAT IS KNOWN ALREADY Male chlamydial infection has been understudied despite male and female infections occurring at similar rates. This is particularly true of asymptomatic infections, which occur in 50% of cases. Chlamydial infection has also been associated with increased sperm DNA damage and reduced male fertility. STUDY DESIGN, SIZE, DURATION We collected diagnostic (fixed, n = 100) and therapeutic (fresh, n = 18) human testicular biopsies during sperm recovery procedures from moderately to severely infertile men in a cross-sectional approach to sampling. PARTICIPANTS/MATERIALS, SETTING, METHODS The diagnostic and therapeutic biopsies were tested for Chlamydia-specific DNA and protein, using real-time PCR and immunohistochemical approaches, respectively. Serum samples matched to the fresh biopsies were also assayed for the presence of Chlamydia-specific antibodies using immunoblotting techniques. MAIN RESULTS AND THE ROLE OF CHANCE Chlamydial major outer membrane protein was detected in fixed biopsies at a rate of 45.3%. This was confirmed by detection of chlamydial DNA and TC0500 protein (replication marker). C. trachomatis DNA was detected in fresh biopsies at a rate of 16.7%, and the sera from each of these three positive patients contained C. trachomatis-specific antibodies. Overall, C. trachomatis-specific antibodies were detected in 72.2% of the serum samples from the patients providing fresh biopsies, although none of the patients were symptomatic nor had they reported a previous sexually transmitted infection diagnosis including Chlamydia. LIMITATIONS, REASONS FOR CAUTION No reproductively healthy male testicular biopsies were tested for the presence of Chlamydia DNA or proteins or Chlamydia-specific antibodies due to the unavailability of these samples. WIDER IMPLICATIONS FOR THE FINDINGS Application of Chlamydia-specific PCR and immunohistochemistry in this human male infertility context of testicular biopsies reveals evidence of a high prevalence of previously unrecognised infection, which may potentially have a pathogenic role in spermatogenic failure. STUDY FUNDING/COMPETING INTEREST(S) Funding for this project was provided by the Australian NHMRC under project grant number APP1062198. We also acknowledge assistance from the Monash IVF Group and Queensland Fertility Group in the collection of fresh biopsies, and the Monash Health and co-author McLachlan (declared equity interest) in retrieval and sectioning of fixed biopsies. E.M. declares an equity interest in the study due to financing of fixed biopsy sectioning. All other authors declare no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
Considering infection/inflammation to be an important risk factor in male infertility, the aim of this study was to make a comprehensive evaluation of the prevalence of urogenital tract infection/inflammation and its potential impact on sperm retrieval in azoospermic patients. In this prospective study, 71 patients with azoospermia were subjected to an extensive andrological workup including comprehensive microbiological diagnostics (2-glass test, semen, testicular swab and testicular tissue analysis) and testicular biopsy/testicular sperm extraction (TESE). Medical history suggested urogenital tract infection/inflammation in 7% of patients, 11% harboured STIs, 14% showed significant bacteriospermia, 15% had seminal inflammation, 17% fulfilled the MAGI definition, and 27% had relevant pathogens. At the testicular level, 1 patient had a swab positive for bacteria, no viruses were detected, tissue specimens never indicated pathogens, whereas histopathology revealed focal immune cell infiltrates in 23% of samples. Testicular sperm retrieval rate was 100% in obstructive and 46% in nonobstructive azoospermia. None of the infection/inflammation-related variables was associated with the success of sperm retrieval or inflammatory lesions in the testis. The high prevalence of urogenital infection/inflammation among azoospermic men underpins their role as significant aetiologic factors in male infertility. However, this observation does not refer to the chances of sperm retrieval at the time of surgery/TESE.

Abstract
A reliable overview of data on the prevalence of Chlamydia trachomatis (CT) in Russia is lacking and needed. All the available data on CT prevalence were analyzed in a systematic literature review on CT prevalence in Russia, strengthened with data from the multicenter study among 1263 people in the second-largest Russian megalopolis, St. Petersburg, testing for CT DNA in urethral, anal, cervical and prostate samples. A total of 10 articles met the inclusion criteria. The overall average prevalence of genital CT infections in Russian populations ranged from 2.9% to 33%. Risk factors included being symptomatic (P = 0.004; in men P < 0.001), being younger than 30 years (P = 0.001) and being a man who has sex with men (MSM) (P = 0.0084). Main limitations included the lack of studies in MSM. CT prevalence was higher in the groups where urethral and prostate secretion samples were pooled (5.2%-7.3% vs 3.2% in the urethra only). The data on CT prevalence in a range of Russian populations are analyzed and reported. Prostate secretions represent an additional sampling material for the study of CT infection in men. CT detection in some settings in St. Petersburg yielded levels of reliability comparable with internationally available tests. The initiation of screening programs for Chlamydia infections in Russia should be considered.

Abstract
In this prospective study, the fully automated cobas 4800 CT/NG and the cobas TaqMan CT tests were compared for Chlamydia trachomatis detection in urine and in genital specimens collected with Copan flocked swabs in culture media. A protocol was also established for the highly sensitive detection of C. trachomatis in semen specimens using the cobas 4800 CT/NG test. A total of 708 consecutive urogenital samples (293 male urine samples and 356 vaginal, 45 cervical and 14 urethral swabs) obtained from the Bacteriology Department, as well as 100 consecutive semen samples collected from patients attending the Reproduction Biology Department, Bordeaux University Hospital, France, from July to September 2010, were analysed. Positive and negative agreements between the cobas 4800 CT/NG and cobas TaqMan CT tests were 92.7 % [95 % confidence interval (CI), 82.7-97.1 %] and 99.2 % (95 % CI, 98.2-99.7 %), respectively, with an overall agreement of 98.7 % (699/708). The clinical sensitivity of the cobas 4800 CT/NG assay for C. trachomatis ranged from 90.9 to 100 % depending on specimen type, with an overall prevalence of 7.2 % (51/708). The clinical specificity ranged from 99.1 to 100 % depending on specimen type. Dilution of 25 µl semen samples in cobas PCR medium proved to be the most sensitive protocol with the lowest inhibition rate. In conclusion, the cobas 4800 CT/NG test was found to be an effective method for detection of C. trachomatis in semen, male urine and genital swab samples collected dry or in universal transport medium.

Male rat genital tract infection with Chlamydia muridarum has no significant consequence on male fertility. J Urol 2012; 187:1911-7.

Abstract
PURPOSE Chlamydia trachomatis infection of the male genital tract was proposed to alter male fertility. We studied the putative consequences of chlamydial male genital tract infection on semen quality and male fertility in an experimental rat model of infection. MATERIALS AND METHODS We used 36 male and 40 female Wistar rats. Male genital infection was created by inoculating Chlamydia muridarum in the meatal urethra. The presence of C. muridarum was evaluated by polymerase chain reaction in semen and male genital tract organs early (15 days) and late (80 days) after infection. Sperm quality parameters were assayed in seminal and epididymal sperm from sham infected and infected rats. Mating studies with sexually mature females were performed and fertility parameters were assayed, including potency, fecundity and fertility indexes, fetal size, and pre-implantation and post-implantation embryo loss. RESULTS Male rats showed ascending, disseminated infection 15 days after infection. Bacteria persisted in the prostate and seminal vesicles 80 days after infection. C. muridarum was detected in semen in most rats regardless of acute or chronic infection. Seminal or epididymal sperm quality did not differ in infected and sham infected rats 15 or 80 days after infection. Sperm apoptosis was also minimal in infected rats. No differences were observed in fertility parameters between infected and sham infected rats. CONCLUSIONS C. muridarum infects the rat male genital tract and persists mainly in the prostate. Although C. muridarum was detected in semen during acute and chronic infection, no alterations in sperm quality were observed. C. muridarum infection does not impair male fertility.
