This study primarily aimed to investigate the prevalence of human papillomavirus (HPV) and other common pathogens of sexually transmitted infections (STIs) in spermatozoa of infertile men and their effects on semen parameters. These pathogens included Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae, Pseudomonas aeruginosa , and Staphylococcus aureus . A total of 1951 men of infertile couples were recruited between 23 March 2023, and 17 May 2023, at the Department of Reproductive Medicine of The First People's Hospital of Yunnan Province (Kunming, China). Multiplex polymerase chain reaction and capillary electrophoresis were used for HPV genotyping. Polymerase chain reaction and electrophoresis were also used to detect the presence of other STIs. The overall prevalence of HPV infection was 12.4%. The top five prevalent HPV subtypes were types 56, 52, 43, 16, and 53 among those tested positive for HPV. Other common infections with high prevalence rates were Ureaplasma urealyticum (28.3%), Ureaplasma parvum (20.4%), and Enterococcus faecalis (9.5%). The prevalence rates of HPV coinfection with Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae , and Staphylococcus aureus were 24.8%, 25.4%, 10.6%, 6.4%, 2.4%, 7.9%, 5.9%, 0.9%, and 1.3%, respectively. The semen volume and total sperm count were greatly decreased by HPV infection alone. Coinfection with HPV and Ureaplasma urealyticum significantly reduced sperm motility and viability. Our study shows that coinfection with STIs is highly prevalent in the semen of infertile men and that coinfection with pathogens can seriously affect semen parameters, emphasizing the necessity of semen screening for STIs.

Objective:
To analyze the relationship of Mycoplasma genitalium (MG) infection with routine semen parameters and sperm DNA integrity in male infertility patients.
METHODS:
Totally, 114 semen samples, 34 MG-positive and 80 MG-negative, were collected from male infertility patients and subjected to routine semen analysis with the computer-assisted sperm analysis system, Papanicolaou staining for observation of sperm morphology, and sperm chromatin diffusion (SCD) test for detection of sperm DNA integrity. Semen parameters and DNA integrity were compared between the MG-positive and MG-negative groups with SPSS 21.0 statistical software and the relationship between the semen parameters and DNA integrity analyzed by Pearson correlation analysis.
RESULTS:
The MG-positive samples, compared with the MG-negative ones, showed significantly decreased semen volume ([2.87 ± 0.37] vs [3.86 ± 0.43] ml, P < 0.01), sperm concentration ([29.05 ± 6.17] vs [32.56 ± 5.97] ×10⁶/ml, P < 0.01), and percentages of progressively motile sperm (PMS) ([15.86 ± 2.79]% vs [23.65 ± 3.47]%, P < 0.01) and morphologically normal sperm (MNS) ([6.35 ± 2.06]% vs [7.14 ± 1.89]%, P < 0.05), increased proportions of non-halo sperm ([15.02 ± 3.52]% vs [9.72 ± 2.94]%, P <0.01) and small-halo sperm ([16.37 ± 5.26]% vs [11.07 ± 1.65]%, P < 0.01) and sperm DNA fragmentation index (DFI) ([31.39 ± 3.16]% vs [20.79 ± 3.59]%, P < 0.01), and reduced proportion of large-halo sperm ([54.75 ± 8.74]% vs [64.15 ± 9.76]%, P < 0.01). DFI was negatively correlated with the percentages of PMS (r = -0.516, P < 0.05) and MNS (r = -0.429, P < 0.05) in the MG-positive group, but not correlated with any of the routine semen parameters in the MG-negative patients (P > 0.05).
CONCLUSIONS
MG infection may be an important factor affecting sperm quality in male infertility patients. Active prevention and treatment of MG infection can help prevent male infertility.

ObjectiveTo explore Mycoplasma genitalium (MG) infection in the urogenital tract of infertile men and its influence on semen quality.
METHODSSemen samples were collected from 352 infertile males in the Center of Reproductive Medicine of Nanjing General Hospital from March to July 2015. MG infection was detected by real-time fluorescence simultaneous amplification and testing and semen analyses were conducted according to the WHO Laboratory Manual for the Examination and Processing of Human Semen (5th Ed) on the semen pH value, semen volume, total sperm count, sperm concentration, total sperm motility, percentages of progressively motile sperm (PMS) and immotile sperm (IMS), and sperm DNA fragmentation index (DFI). The data obtained were subjected to statistical analysis by t-test and non-parametric test (Wilcoxon test).
RESULTSMG infection was found in 3.4% (12/352) of the infertile patients. Compared with the MG-positive cases, the MG-negative ones showed a significantly higher semen volume ([2.85 ± 0.14] vs [3.84 ± 0.12] ml, P = 0.008) and percentage of PMS ([15.86±1.72] vs [60.95 ± 5.63] %, P = 0.032) but a lower DFI ([30.73 ±2.24] vs [20.71 ± 1.55]%, P = 0.014). However, no statistically significant differences were observed between the two groups in the semen pH value (7.38 ±0.02 vs 7.39 ± 0.01, P = 0.774), sperm concentration ([52.96 ± 15.78] vs [60.05 ± 4.29]×10⁶/ml, P = 0.683), sperm count ([154.15 ± 46.37] vs [221.56 ± 15.43]×106, P = 0.236), total sperm motility ([29.04 ± 3.11] vs [33.52 ± 1.51] %, P = 0.626), or percentage of IMS ([23.57 ± 0.99] vs [62.34 ± 1.69] %, P = 0.691).
CONCLUSIONSUrogenital MG infection is common in infertile males and potentially affects the semen quality, especially sperm vitality of the patient.

5.Impact of Mycoplasma and Chlamydia infections on male reproduction.
National Journal of Andrology 2017;23(2):183-188
Infertility can be attributed to reproductive tract infections (RTI), most commonly nongonococcal urethritis, mainly including Mycoplasma and Chlamydia infections, which may directly or indirectly damage spermatozoa and spermatogenic cells. In addition, a series of immune responses caused by such infections are also associated with male infertility. Methods for the clinical detection of these microbial infections are being constantly improved for more specific and precise control over the impact of Mycoplasma and Chlamydia infections on male fertility.

Mycoplasma hominis (M. hominis) and Ureaplasma urealyticum (U. urealyticum) are important opportunistic pathogens that cause urogenital infections and complicate pregnancy. The aim of this study was to investigate the prevalence, effects on pregnancy outcomes, and antimicrobial susceptibilities of M. hominis and U. urealyticum. We tested vaginal swabs obtained from 1035 pregnant women for the presence of genital mycoplasmas between June 2009 and May 2014. The laboratory and clinical aspects of genital mycoplasmas infection were reviewed retrospectively, and the identification and antimicrobial susceptibility of genital mycoplasmas were determined using the Mycoplasma IST-2 kit. A total of 571 instances of M. hominis and/or U. urealyticum were detected. Of them, M. hominis was detected in two specimens, whereas U. urealyticum was detected in 472 specimens. The remaining 97 specimens were positive for both M. hominis and U. urealyticum. Preterm deliveries were frequently observed in cases of mixed infection of M. hominis and U. urealyticum, and instances of preterm premature rupture of membrane were often found in cases of U. urealyticum. The rates of non-susceptible isolates to erythromycin, empirical agents for pregnant women, showed increasing trends. In conclusion, the prevalence of M. hominis and/or U. urealyticum infections in pregnant women is high, and the resistance rate of antimicrobial agents tends to increase. Therefore, to maintain a safe pregnancy, it is important to identify the isolates and use appropriate empirical antibiotics immediately.

The role of atypical bacteria and the effect of antibiotic treatments in acute bronchitis are still not clear. This study was conducted at 22 hospitals (17 primary care clinics and 5 university hospitals) in Korea. Outpatients (aged > or = 18 yr) who had an acute illness with a new cough and sputum (< or = 30 days) were enrolled in 2013. Multiplex real-time polymerase chain reaction (RT-PCR) was used to detect five atypical bacteria. A total of 435 patients were diagnosed as having acute bronchitis (vs. probable pneumonia, n = 75), and 1.8% (n = 8) were positive for atypical pathogens (Bordetella pertussis, n = 3; B. parapertussis, n = 0; Mycoplasma pneumoniae, n = 1; Chlamydophila pneumoniae, n = 3; Legionella pneumophila, n = 1). Among clinical symptoms and signs, only post-tussive vomiting was more frequent in patients with atypical pathogens than those without (P = 0.024). In all, 72.2% of the enrolled patients received antibiotic treatment at their first visits, and beta-lactams (29.4%) and quinolones (20.5%) were the most commonly prescribed agents. In conclusion, our study demonstrates that the incidence of atypical pathogens is low in patients with acute bronchitis, and the rate of antibiotic prescriptions is high.

OBJECTIVETo investigate the changes in cytokines (IL-1beta, IL-2, TNF-alpha) of peripheral blood and cervical mucous of infertile women with mycoplasma infection and the effect of intervention of traditional Chinese medicines (TCMs).
METHODAccording to the results of culture of mycoplasma from genital tracts, 72 patients with positive mycoplasma were randomly divided into the TCM group (38 cases) and the western medicine group (34 cases). The western medicine group was treated with 0.5 g azithromycin for 3 days and consecutively treated for six courses of treatment, each course of treatment of 4 days. The TCM group were treated with Xiaozhi decoction twice every day for 6 weeks. The IL-1beta, IL-2 and TNF-alpha levels of the peripheral blood and cervical mucous of the two groups were measured by the Ria testing before and after the treatment, and the mycoplasma culture (-) of 32 infertile women as set for control.
RESULTBefore the treatment, TNF-alpha and IL-1beta in levels of the two treatment groups were higher than those of the control group (P < 0.01). In the TCM group, TNF-alpha and IL-1beta levels showed significant differences compared with those before the treatment (P < 0.05) and those of the western group after the treatment (P < 0.01); and IL-2 level didn't have significant change before and after the treatment. The cytokines in peripheral blood of the two treatment groups showed notable difference compared with those of the control group (P < 0.01). In TCM group, IL-2 level had remarkable difference compared with that before the treatment (P < 0.01) and compared with the control group after the treatment (P < 0.01).
CONCLUSIONCytokines (IL-1beta, IL-2, TNF-alpha) in the peripheral blood and cervical mucous increase in infertile women with the mycoplasma infection, suggesting that TCMs can effectively inhibit the levels of IL-1beta, IL-2, TNF-alpha in the peripheral blood and IL-1beta, TNF-alpha in cervical mucous. It is proved that Xiaozhi decoction can be used to treat infertile women with mycoplasma infection.
