Abstract
PURPOSE Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and Mycoplasma hominis (MH), the three most common treatable bacterial sexually transmitted infections (STIs) worldwide can lead to many complications if remain untreated. Screening of high-risk population with highly sensitive methods will lead to significant improvement in patient outcomes and will prevent downward transmission. The advantages of Polymerase chain reaction (PCR) based assay are not only high sensitivity and specificity, but also detection of multiple organisms in a single reaction which reduce the result turn-around time. The aim of the present study was to evaluate the feasibility of a multiplex PCR assay method targeting 16S rRNA gene for simultaneous detection of NG, CT and MH infection along with their trend and occurrence among high-risk population in Assam, Northeast India. METHODS A cross-sectional study was undertaken, where a total of 200 randomly selected patients from high-risk population were included. After validation of singleplex PCR, Multiplex PCR (M-PCR) was performed along with the traditional culture method for NG. RESULTS & CONCLUSION The overall agreement of M-PCR with singleplex PCR was very high (100%). The occurrence of STI was found to be very high (101/200; 50.5%). Furthermore, co-infection was detected in 10/200; 5%) individuals. Infection was more common among young individuals (p < 0.05) and males out-numbered females (p < 0.05). The most common organism detected was CT (42/200; 21%) followed by NG (41/200; 20.5%) and MH (20/200; 10%). The M-PCR assay workflow is simple, cost effective and can be used in routine diagnostic laboratories with basic molecular facilities.

Abstract
Monitoring astronauts' health during space missions poses many challenges, including rapid assessment of crew health conditions. Sensitive genetic diagnostics are crucial for examining crew members and the spacecraft environment. CRISPR-Cas12a, coupled with isothermal amplification, has proven to be a promising biosensing system for rapid, on-site detection of genomic targets. However, the efficiency and sensitivity of CRISPR-based diagnostics have never been tested in microgravity. We tested the use of recombinase polymerase amplification (RPA) coupled with the collateral cleavage activity of Cas12a for genetic diagnostics onboard the International Space Station. We explored the detection sensitivity of amplified and unamplified target DNA. By coupling RPA with Cas12a, we identified targets in attomolar concentrations. We further assessed the reactions' stability following long-term storage. Our results demonstrate that CRISPR-based detection is a powerful tool for on-site genetic diagnostics in microgravity, and can be further utilized for long-term space endeavors to improve astronauts' health and well-being.

Abstract
INTRODUCTION Neisseria gonorrhoeae causes gonorrhoea, a globally neglected but increasing disease. This systematic review and meta-analysis reviewed the epidemiology and economic burden of gonorrhoea in Latin America and the Caribbean (LAC). METHODS We searched PubMed, EMBase, Cochrane Library, EconLIT, CINAHL, CRD, LILACS, Global Health, Global Dissertations and Theses, SciELO, Web of Science databases, countries' ministries of health, and the IHME's Global Burden of Disease databases. Studies published in the last 10 years (20 years for economic studies) were included if conducted in any LAC country, without language restrictions. The main outcome measures were incidence/prevalence, proportion of co-infections, case fatality rates, specific mortality/hospitalisation rates, direct/indirect costs, and impact of gonorrhoea on quality of life. To assess evidence quality, we used a checklist developed by the US National Heart, Lung, and Blood Institute for observational studies and trial control arms, the Cochrane Effective Practice Organization of Care Group tool for randomised controlled trials, and the CICERO checklist for economic studies. RESULTS We identified 1290 articles; 115 included epidemiological studies and one included an economic study. Ministry of health data from Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay were identified. Gonorrhoea prevalence was 1.46% (95% confidence interval [CI] 1.00-2.00%) from 48 studies and 5.68% (95% CI 4.23-7.32%) from 58 studies for non-high-risk and high-risk populations, respectively. Cumulative incidence for the high-risk population was 2.05 cases per 100 persons/year. Few published studies were rated as "good" in the risk of bias assessments. Variations in the methodology of the sources and limited information found in the countries' surveillance systems hinder the comparison of data. CONCLUSION The burden of gonorrhoea in LAC is not negligible. Our results provide public health and clinical decision support to assess potential interventions to prevent gonorrhoea. TRIAL REGISTRATION The protocol is registered on PROSPERO (CRD42021253342). The study was funded by GlaxoSmithKline Biologicals SA (GSK study identifier VEO-000025).

Abstract
Sexually transmitted infections (STIs) represent a global health problem with
variable prevalence depending on the geographical region and the type of
population. Human papillomavirus (HPV) encompasses widespread virus types
related to cervical carcinogenesis. The present study investigated the molecular
prevalence of HPV and seven other important STIs in asymptomatic women working
or studying at a Brazilian university. A secondary aim was to assess cytological
abnormalities associated with HPV and other STIs coinfections. We recruited 210
women from a Brazilian university. HPV was detected using a single-round
polymerase chain reaction (sPCR) followed by a viral genotyping by restriction
fragment length polymorphism (RFLP-PCR). The presence of seven STIs:
Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum,
Trichomonas vaginalis, Mycoplasma genitalium, herpes simplex virus
(HSV)-1 and HSV-2 was detected by multiplex PCR (M-PCR). Furthermore,
cytological findings and epidemiological characteristics were evaluated.The mean
age of the participants was 27.1 years old. HPV prevalence was 33.8%, and HPV16
was the most frequently detected papillomavirus genotype. Moreover, multiple HPV
infections were common (42.2%). We detected at least one STI agent in 11.4% of
the tested women, most frequently C. trachomatis (6.7%). Among
HPV-positive women, 14.1% were coinfected with other STI agents. Cytological
abnormalities were observed in 9.5% of smears, and HPV-DNA, high-risk HPV
(HR-HPV), HPV16 and HPV multiple infections were associated with abnormal
cytological findings. There was a high prevalence of HPV, and C.
trachomatis was the most prevalent STI agent, with low rates of
cytological abnormalities. These findings highlight the need of timely STI
diagnosis in young asymptomatic women and of a public policy design for STI
prevention.

Abstract
OBJECTIVE To verify the association between HPV infection and the presence of coinfections (Chlamydia trachomatis, Trichomonas vaginalis, and Neisseria gonorrhoeae) in women in the state of Maranhão. METHODS HPV-DNA detection was performed by the nested PCR, using the primers PGMY09/11 and GP + 5/GP + 6. For the identification of sexually transmitted agents, conventional PCR was performed using the following primers: KL1/KL2 (Chlamydia trachomatis), TVA5/TVA6 (Trichomonas vaginalis), and HO1/HO3 (Neisseria gonorrhoeae). DNA-HPV positive samples were subjected to automated sequencing for genotyping. RESULTS Among the 353 women evaluated, 204 (57.8%) had HPV-DNA, of which 140 (68.6%) exhibited HPV/STIs, while 64 (31.4%) had the only HPV. T. vaginalis infection showed a positive association with HPV (p=0.003). Women without cervical lesions were predominant (327/92.6%); however, the largest number of lesions was reported in women who had HPV/coinfections (18/8.8%). Multiple regression analysis showed that both HPV only and the concomitant presence of HPV/STI were able to indicate the occurrence of epithelial lesions (R = 0.164; R2 = 0.027). CONCLUSION The findings suggest that the presence of T. vaginalis can contribute to HPV infection, and HPV/IST association may influence the development of cervical intraepithelial lesions that are precursors of cervical cancer.

Abstract
The frequently asymptomatic sexually transmitted infections (STIs) caused by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) are poorly diagnosed in Brazil and can lead to severe complications/sequelae without timely detection and treatment. We investigated prevalence of CT, NG, and MG infections and associated demographic, behavioral, and clinical factors in consecutive women attending a gynecology and obstetrics outpatient clinic in Pelotas, Southern Brazil. Vaginal swab samples were prospectively obtained from asymptomatic and symptomatic women (n = 498) from August 2015 to December 2016 and tested with Aptima Combo2 and Aptima M. genitalium assays (Hologic). The prevalence of CT, NG, and MG was 6.8% (34/498), 1.0% (5/498), and 4.2% (21/498), respectively. Three (0.6%) cases of CT and NG co-infection and one (0.2%) case of CT and MG co-infection were identified. The risk factors associated with these bacterial STIs were youth (<30 years), no steady sexual partner, infection with additional STI, and lack of income. Bacterial STIs, particularly CT and MG, were prevalent among women, including pregnant women (60% of positive cases), in Pelotas, Brazil. Sensitive and specific diagnostic testing and early treatment are essential to control STIs, limit transmission chains, avoid future complications/sequelae, and reduce health and cost burdens on the population.

Abstract
Background Chlamydia trachomatis may coinfect with human papillomavirus (HPV) and complicate the cervical pathogenesis. This study aimed to evaluate the prevalence, risk factors, and clinical outcomes of HPV/C. trachomatis coinfection in women from Inner Mongolia, China. Methods We performed a polymerase chain reaction (PCR)-based HPV/C. trachomatis screening and cervical samples were analyzed by thinprep cytologic test. Statistical analysis was used to assess the association between demographic factors and coinfection. Results Among the 2345 women recruited, the prevalences of HPV, C. trachomatis, and HPV/C. trachomatis coinfection were 36.0%, 14.3%, and 4.8%, respectively. The rate of multiple HPV genotypes was higher in coinfected women. HPV66 was the most frequently identified genotype in coinfected participants. The HPV DNA load was significantly higher in HPV monoinfected cases. In contrast, the DNA load of C. trachomatis was significantly higher in the coinfection group. Risk factors, including single women (odds ratio [OR] = 6.0, 95% confidence interval [CI], 4.044-8.782) and women with multiple sex partners (OR = 1.9, 95% CI, 1.324-2.824), were associated with coinfection. Importantly, coinfection was associated with increased risk for high-grade squamous intraepithelial lesions. Conclusions HPV and C. trachomatis coinfection is an important risk factor for the progression of cervical lesions.

Abstract
The aim of this study was to evaluate the prevalence of herpes simplex virus 2 (HSV-2) and HSV-2/human papillomavirus (HPV) co-infection by self-collected samples compared to clinician-collected samples in human immunodeficiency virus 1 (HIV-1)-infected and -uninfected women from the Tapajós region, Amazon, Brazil. A cross-sectional study was conducted with 439 anal and cervical scrapings and cervico-vaginal self-collected samples obtained from 153 eligible HIV-infected and -uninfected women. Real-time PCR for HSV-2 and nested PCR for HPV detection were performed. A multivariate analysis identified risk factors for HSV-2/HPV co-infection. The anogenital prevalence of HSV-2 was 9.2% (14/153), HPV was 67.3% (103/153) and HSV-2/HPV co-infection was 6.5% (10/153). There was a significant overall agreement (95.5%, 11/133, kappa 0.64, 95% CI 0.38–0.90, p < 0.0001) for HSV-2 detection by the self-collected and clinician-collected samples. HSV-2 genital infection was more prevalent than anal infection in all participants. HIV-infected women had a higher prevalence of HSV-2 and HSV-2/HPV. No woman with a cervical squamous intraepithelial lesion had HSV-2/HPV co-infection. Risk factors for HSV-2/HPV were age ≤25 years (aOR = 10.07) and being single (aOR = 3.79). In general, young and single women are at greater risk for HSV-2/HPV infection. Self-collection can be a useful strategy for the screening of HSV-2 and HPV in limited-resource settings.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the central factor for cervical cancer, whereas epithelial immune mechanisms contribute to the progression of HPV infection and its associated lesions. The authors evaluated the expression of indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) in cervicovaginal samples from women with normal cervical epithelium or with different degrees of squamous intraepithelial lesions (SILs) and cervical cancer. METHODS IDO expression was analyzed by immunocytochemistry in liquid-based cytology samples from 165 women, of whom 42 had cervical changes subclassified as low-grade SIL (n = 6), high-grade SIL (n = 30), or squamous cell carcinoma (SCC) (n = 6), and 123 had negative Papanicolaou smears. IDO and TDO expression also were analyzed by immunohistochemistry, and HPV and other genital pathogens were evaluated by polymerase chain reaction analysis. RESULTS Low IDO expression was observed in normal cervical epithelium irrespective of HPV status. Increased numbers of IDO-positive squamous cells and IDO-positive leukocytes were observed in women with SIL or SCC. TDO expression was detected in leukocytes infiltrating the stroma around intraepithelial or invasive cervical lesions. Higher IDO levels were detected in organotypic epithelial cultures established from keratinocytes transduced with the HPV16 E6/E7 oncoproteins. CONCLUSIONS The upregulation of IDO expression in leukocytes and squamous cells in HPV-associated SIL and SCC suggests that immunosuppressive mechanisms involving tryptophan metabolism may have a role in cervical carcinogenesis. Although previous studies have suggested the role of IDO in HPV pathogenesis, this is the first evidence of TDO involvement in the process. Furthermore, the current data emphasize the role of leukocytes, especially neutrophil-like cells, as an IDO source.

Background A high proportion of men who have sex with men (MSM) use geosocial networking apps (Apps) to seek partners. However, the relationship of app use with HIV risk is unknown. Further, the risks of some sexually transmitted infection (STIs), including Mycoplasma genitalium, have seldom been studied among MSM. Methods MSM were enrolled at a community-based HIV testing site in Shenyang, China. After completing a questionnaire survey, we collected rectal swabs and venous blood specimens. We then simultaneously tested for ten STIs (Chlamydia trachomatis [CT], Neisseria gonorrhea [NG], Ureaplasma urealyticum [Uu], Ureaplasma parvum species [Up1, Up3, Up6, Up14), Mycoplasma hominis [Mh], Mycoplasma genitalium [Mg], and Herpes Simplex Virus Type 2 (HSV-2) using multiple PCR. We also performed blood tests for HIV, Syphilis, Hepatitis C antibody (HCV-Ab), Hepatitis B Surface Antigen (HBsAg), and Hepatitis A-IgM (HAV-IgM), etc. Results One hundred and eighty-three MSM participated in this study, of which 51.4% reported seeking partners through apps in the past year. The prevalence of HIV was 19.7%, Syphilis 12.0%, HAV 1.1%, rectal Mg 15.3% and Mh 7.1%. Multivariable logistic regression showed that HIV infection was independently correlated with app-using behavior (adjusted odds ratio[aOR] = 2.6), Mg infection (aOR = 3.2), Mh infection (aOR = 4.1) and Syphilis infection (aOR = 3.1) (each P < 0.05). Conclusions App use, Mg, Mh and Syphilis infection were correlated with higher HIV Risk in MSM. Geosocial networking apps should be utilized for HIV interventions targeting MSM. There is a need for more expansive STIs screening, particularly for Mg, Mh and Syphilis in MSM.

Abstract
The anogenital prevalence of sexually transmitted infections (STIs) and the use of cervico-vaginal self-collected vs. clinician-collected samples were evaluated for the diagnosis of human immunodeficiency virus (HIV)-infected and HIV-uninfected women in the Tapajós region, Amazon, Brazil. We recruited 153 women for a cross-sectional study (112 HIV-uninfected and 41 HIV-infected) who sought health services. Anal and cervical scrapings and cervico-vaginal self-collection samples were collected. Real-time polymerase chain reaction methods were used for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Mycoplasma genitalium. A syphilis test was also performed. Risk factors for STIs were identified by multivariate analysis. The overall prevalence of STIs was 30.4% (34/112) in HIV-uninfected women and 24.4% (10/41) in HIV-infected women. Anogenital Chlamydia trachomatis infection was the most prevalent in both groups of women (20.5% vs 19.5%). There was significant agreement for each STI between self-collected and clinician-collected samples: 91.7%, kappa 0.67, 95% confidence interval (CI) 0.49-0.85 for Chlamydia trachomatis; 99.2%, kappa 0.85, 95% CI 0.57-1.00 for Neisseria gonorrhoeae; 97.7%, kappa 0.39, 95% CI -0.16-0.94 for Trichomonas vaginalis; and 94.7%, kappa 0.51, 95% CI 0.20-0.82 for Mycoplasma genitalium. Women with human papillomavirus had coinfection or multiple infections with other STIs. Risk factors for STIs were being ≤ 25 years old, being employed or a student, reporting a history of STI and having a positive HPV test. A high prevalence of STIs in women in the Tapajós region was found. Cervico-vaginal self-collection is a useful tool for STI screening and can be used in prevention control programs in low-resource settings, such as in northern Brazil.

Abstract
RESEARCH QUESTION Is there an association between the presence of sexually transmitted pathogens in the lower (LGT) and upper (UGT) female genital tract with endometriosis and infertility? DESIGN Case-control study with 60 women submitted to gynaecological laparoscopic surgery. Samples from the UGT and LGT were collected and analysed by single polymerase chain reaction (PCR) for human papillomavirus (HPV) and by multiplex PCR for other sexually transmitted infections (STI). Patients were initially divided into two clinical groups: infertile patients (n = 25) with conjugal infertility and fertile control patients (n = 35). After the surgical findings patients were further divided for additional analysis: an endometriosis group (n = 29) and non-endometriosis control group (n = 31). RESULTS Sixty per cent of patients were positive for DNA-HPV in some of the genital tract sites sampled. Infertile patients were associated with high-risk HPV (hrHPV) positivity in the UGT sites (P = 0.027). The endometriosis group was associated with hrHPV positivity in the LGT and UGT sites (P = 0.0002 and P = 0.03, respectively). Only hrHPV types were detected in the UGT in both groups. It may be that there is a hrHPV infection continuum, from LGT to UGT, in infertile and endometriosis patients. No association was observed among the other seven STI studied. CONCLUSIONS This study shows both an association between hrHPV infections in the UGT with infertility and endometriosis, and a possible hrHPV infection continuum, from LGT to UGT. Larger studies are needed to fully investigate the role of hrHPV as a cause of endometriosis and infertility.

Abstract
BACKGROUND Human herpesvirus 2 (HHV-2) have DNA genome with a limited genetic variability and have been classified into two clades. OBJECTIVES To identify and characterise six HHV-2 isolates derived from Brazilian women. METHODS HHV-2 isolates were performed polymerase chain reaction (PCR) and sequencing of 2250 pb of the glycoprotein B (gB) coding regions. FINDINGS Four HHV-2 isolates were classified into clade B, while the remaining two, derived from HIV-1 co-infected women, showed a notable genetic divergence (> 1%). MAIN CONCLUSION The results reveal novel HHV-2 variants. The impact of these novel variants on HHV-2 pathogenesis and HIV/HHV-2 coinfection need to be investigated.

Abstract
Trichomonas vaginalis infections have been associated with other diseases so that epidemiological studies of the parasite are important and help to prevent the spread of the disease. This study aimed to determine the prevalence of T. vaginalis in female patients of 19 counties in southwestern Rio Grande do Sul, Brazil. For diagnosis, was used direct examination, followed by applying a socio-epidemiological questionnaire. We analyzed 300 women and 9% were infected by Trichomonas vaginalis. The highest frequency occurred in women between 18 and 39 years old, single/divorced/widowed, whose family income was at one minimum wage or less, and they had not completed the primary school. Statistically significant risk factors were: women reporting two or more sexual partners in the last year were 3.3 times more likely to acquire the parasite, and those in use of oral contraceptives were 2.7 times more likely to have T. vaginalis. Importantly, 33% of the asymptomatic women were infected, and most of the negative results were from women presenting symptoms consistent with the infection. The findings emphasize that it is necessary to expand the knowledge of individuals about the disease, especially among women with the above mentioned risk factors and also to include the regular screening of Trichomonas vaginalis infections in health centers.

Abstract
The link between high-risk human Papillomavirus (HR-HPV) and other sexually transmitted diseases (STDs) in the risk of developing cervical cancer still unclear. Thus, in this report we investigated the rates of co-infections between HPV and other important non-HPV STDs in different cervical findings using a multiplex polymerase chain reaction (M-PCR) to simultaneously detect Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, HSV-1 and -2, and Treponema pallidum. A total of 838 women aged 18 to 68 years were screened using Papanicolaou smears for cervical abnormalities, HPV and non-HPV STDs using PCR and M-PCR methods. A total of 614 (73.3%) of the women had normal cytology (NILM) and 224 (26.7%) women exhibited abnormal cytology (≥ ASC-US). HPV-DNA prevalence was 33.9%, and HPV-16 was the most prevalent genotype in women with NILM and ≥ ASC-US cytology. Non-HPV STDs were detected in 30.4% women and T. vaginalis was the most prevalent one (11.6%). A higher increased risk of ≥ ASC-US and HSIL occurred in co-infections of HR-HPV with C. trachomatis and N. gonorrhoeae. Co-infections of HPV-DNA and HR-HPV with HSV-2 exhibited a similar increased risk but only with ≥ ASC-US. Co-infections of HPV-DNA and HR-HPV with T. vaginalis demonstrated a similar increased risk of ≥ ASC-US and HSIL. We found that C. trachomatis and N. gonorrhoeae were the primary pathogens associated with HR-HPV for the increased risk for all grades of cervical abnormalities but mainly for HSIL, suggesting a possible synergistic action in cervical lesions progression. Our results reinforce the hypothesis that some non-HPV STDs might play a role as co-factors in HPV-mediated cervical carcinogenesis. These data improve our understanding of the etiology of SCC and may also be useful for disease prevention.

Abstract
The influence of different infectious agents and their association with human papillomavirus (HPV) in cervical carcinogenesis have not been completely elucidated. This study describes the association between cytological changes in cervical epithelium and the detection of the most relevant aetiological agents of sexually transmitted diseases. Samples collected from 169 patients were evaluated by conventional cytology followed by molecular analysis to detect HPV DNA, Chlamydia trachomatis, herpes simplex virus 1 and 2,Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, andTreponema pallidum, besides genotyping for most common high-risk HPV. An association between cytological lesions and different behavioural habits such as smoking and sedentariness was observed. Intraepithelial lesions were also associated with HPV and C. trachomatis detection. An association was also found between both simple and multiple genotype infection and cytological changes. The investigation of HPV and C. trachomatisproved its importance and may be considered in the future for including in screening programs, since these factors are linked to the early diagnosis of patients with precursor lesions of cervical cancer.

Abstract
Bacterial vaginosis (BV) is characterized by a polymicrobial proliferation of anaerobic bacteria and depletion of lactobacilli, which are components of natural vaginal microbiota. Currently, there are limited conventional methods for BV diagnosis, and these methods are time-consuming, expensive, and rarely allow for the detection of more than one agent simultaneously. Therefore, we conceived and validated a multiplex polymerase chain reaction (M-PCR) assay for the simultaneous screening of thirteen bacterial vaginosis-associated agents (BV-AAs) related to symptomatic BV: Gardnerella vaginalis, Mobiluncus curtisii, Mobiluncus mulieris, Bacteroides fragilis, Mycoplasma hominis, Atopobium vaginae, Ureaplasma urealyticum, Megasphaera type I, Clostridia-like bacteria vaginosis-associated bacteria (BVABs) 1, 2, and 3, Sneathia sanguinegens, and Mycoplasma genitalium. The overall validation parameters of M-PCR compared to single PCR (sPCR) were extremely high, including agreement of 99.1% and sensitivity, specificity, and positive predictive values of 100.0%, negative predictive value of 97.0%, accuracy of 99.3%, and agreement with Nugent results of 100.0%. The prevalence of BV-AAs was very high (72.6%), and simultaneous agents were detected in 53.0%, which demonstrates the effectiveness of the M-PCR assay. Therefore, the M-PCR assay has great potential to impact BV diagnostic methods in vaginal samples and diminish associated complications in the near future.

Abstract
Sexually transmitted diseases (STDs) are caused by several pathogens, including bacteria, viruses and protozoa, and can induce male infertility through multiple pathophysiological mechanisms. Additionally, horizontal transmission of STD pathogens to sexual partners or vertical transmission to fetuses and neonates is possible. Chlamydia trachomatis, Ureaplasma spp., human papillomavirus, hepatitis B and hepatitis C viruses, HIV-1 and human cytomegalovirus have all been detected in semen from symptomatic and asymptomatic men with testicular, accessory gland and urethral infections. These pathogens are associated with poor sperm quality and decreased sperm concentration and motility. However, the effects of these STD agents on semen quality are unclear, as are the effects of herpes simplex virus type 1 and type 2, Neisseria gonorrhoeae, Mycoplasma spp., Treponema pallidum and Trichomonas vaginalis, because few studies have evaluated the influence of these pathogens on male infertility. Chronic or inadequately treated infections seem to be more relevant to infertility than acute infections are, although in many cases the exact aetiological agents remain unknown.

Abstract
Sexually transmitted diseases (STDs) may impair sperm parameters and functions thereby promoting male infertility. To date limited molecular studies were conducted to evaluate the frequency and type of such infections in semen Thus, we aimed at conceiving and validating a multiplex PCR (M-PCR) assay for the simultaneous detection of the following STD pathogens in semen: Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, Herpes virus simplex (HSV) −1 and −2, and Treponema pallidum; We also investigated the potential usefulness of this M-PCR assay in screening programs for semen pathogens. In addition, we aimed: to detect human Papillomavirus (HPV) and genotypes by single PCR (sPCR) in the same semen samples; to determine the prevalence of the seven STDs, HPV and co-infections; to assess the possibility that these infections affect semen parameters and thus fertility. The overall validation parameters of M-PCR were extremely high including agreement (99.2%), sensitivity (100.00%), specificity (99.70%), positive (96.40%) and negative predictive values (100.00%) and accuracy (99.80%). The prevalence of STDs was very high (55.3%). Furthermore, associations were observed between STDs and changes in semen parameters, highlighting the importance of STD detection in semen. Thus, this M-PCR assay has great potential for application in semen screening programs for pathogens in infertility and STD clinics and in sperm banks.
