Abstract
Chronic stress (CS) is shown to decrease the semen quality with changed expression of tyrosine phosphorylated (TyrPho) proteins in testicular and seminal tissues. However, the alterations of such proteins and fluid contents in the epididymis, producing sperm maturation factors, have never been reported. Sixteen adult rats were randomly divided into 2 groups (n = 8). The control animals were not subjected to stressors whereas CS rats were immobilised within restraint cage (4 hr/day) before cold forced-water swimming (15 min/day) for 60 days. Corticosterone, testosterone, blood glucose level (BGL), malondialdehyde (MDA) and biochemical components in epididymal fluid were assayed. Expressions of heat shock protein 70 (HSP-70), androgen receptor (AR) and TyrPho protein were investigated in epididymal tissue and fluid. Significantly, CS increased the corticosterone and BGL but decreased testosterone and epididymal substance levels. MDA level in tail epididymal fluid and HSP-70 expression in both regions of epididymal tissues and fluids, except in head epididymal fluid of CS were increased. Epididymal tissues showed the decrease of AR expression. Presence and changes of many TyrPho proteins were observed in CS. In conclusion, CS could affect functional proteins particularly TyrPho in epididymis, resulted in low semen quality.

Abstract
Aims: It has been estimated that >30% of male infertility cases are of idiopathic etiology. Recent studies revealed a positive connection between periodontal pockets and sperm submotility, which proposes that periodontitis may have a role in male infertility and inadequate semen quality. The aim of the present investigation was to inspect the relationship between male fertility parameters and the periodontal status of male patients attending in vitro treatment (IVF) clinic. Materials and Methods: The study participants comprised 85 men going to the facility for sperm investigation before semen insemination. The nature of sperm was surveyed by the WHO 2010 criteria. On the same day, male patients were examined for periodontal parameters. Results: The patients were determined to have either gingivitis (24.7%) or periodontitis (75.3%). Normospermia was credited to 23.5% and oligozoospermia to 43.5%. Sperm submotility was seen in 76.4% of patients. A higher number of sites with clinical attachment loss showed a positive correlation with sperm submotility and sperm count. Conclusions: The findings of the present study showed a conceivable relationship between male infertility, decreased semen quality, and periodontal diseases in men visiting IVF centers. Periodontitis may subsequently play a role in male infertility.

Genes (Basel) 2017; 8:genes8120371. [PMID: 29292728 PMCID: PMC5748689 DOI: 10.3390/genes8120371] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Revised: 10/30/2017] [Accepted: 11/21/2017] [Indexed: 01/09/2023] Open
Abstract
The aim of the present study was to determine whether mesenchymal stem cell-conditioned medium (MSC-CM) modulates apoptotic and stress-related gene expression, and ameliorates maturation and developmental potential of immature human oocytes after artificial activation. A total of 247 surplus immature germinal vesicle (GV) oocytes obtained from infertile women were allocated into two in vitro maturation (IVM) groups: 1: GV oocytes (n = 116) matured in vitro (fIVM), and 2: GV oocytes (n = 131) that were vitrified, then in vitro matured (vIVM). Also, two maturation media were used: Alpha-minimum essential medium (α-MEM) and human umbilical cord-derived MSCs (hUCM). After 36 h of incubation, the IVM oocytes were examined for nuclear maturation. In IVM-matured oocytes, cytoplasmic maturation was evaluated after artificial activation through Ionomycin. Moreover, the quantitative expressions of B-cell CLL/lymphoma 2 (BCL2), BCL2-associated X protein (BAX), superoxide dismutase (SOD), and Heat shock proteins (HSP70) in matured oocytes were assessed by quantitative Real-time polymerase chain reaction (qRT-PCR) and compared with fresh and vitrified in vivo matured oocytes, which were used as fIVM and vIVM controls, respectively. The highest maturation rate was found in hUCM in fIVM, and the lowest maturation rate was found using α-MEM in vIVM (85.18% and 71.42%, respectively). The cleavage rate in fIVM was higher than that in vIVM (83.4% vs. 72.0%). In addition, the cleavage rate in α-MEM was lower than that in the hUCM (66.0% vs. 89.4%). Furthermore, the difference between parthenote embryo arrested in 4-8 cells (p < 0.04) and the quality of embryo arrested in 8-cell (p < 0.007) were significant. The developmental stages of parthenote embryos in hUCM versus α-MEM were as follows: 2-4 cell (89.45% vs. 66.00%, respectively), 4-8 cell (44.31% vs. 29.11%, respectively), morula (12.27% vs. 2.63%, respectively), and blastocysts (2.5% vs. 0%, respectively). The messenger RNA (mRNA) expression levels of BCL2, BAX and SOD were significantly different (p < 0.05) between the matured IVM oocytes. Overall, hUCM showed potential efficacy in terms of ameliorating oocyte maturation and in promoting the development and mRNA expression of BAX, BCL2, and SOD.

Abstract
Conventional sperm analysis (i.e., motility and fertility) has been used to evaluate sperm quality. Understanding the quality of sperm on the molecular level in the sturgeons, Acipenser baerii and A. schrenckii, is essential for the improvement of the conservation of genetic resources and farming performance. In this study, we used the iTRAQ proteomics approach to perform proteomic profiling of spermatozoa associated with sperm quality in sturgeons (Data are available via ProteomeXchange with identifier PXD006108). The results showed 291 and 359 differentially expressed proteins in A. baerii and A. schrenckii, respectively, of which 72 were common to both species and all were upregulated in high quality compared with low quality samples. The differentially expressed proteins were mainly categorized into the generation of precursor metabolites and energy and oxidation, and they were localized to the mitochondria. Three distinguishing pathways, Arginine and proline metabolism, Pyruvate metabolism and the Citrate cycle (TCA cycle) were found to play an important role in energy metabolism, and some substrates could be used in the sperm medium for storage and cryopreservation. The quantity levels of two proteins, CKMT1 and LDHB, were verified by western blot analysis. Moreover, other potential biomarkers involved in oxidation reduction, ubiquitin-proteasome-dependent proteolysis, chaperones and binding activity were also discussed. Our study is the first to use the iTRAQ-based proteomics approach to analyse the sturgeon spermatozoa proteome, and the results that we obtained are valuable for the prediction of sperm quality and reproduction management in these threatened species.

Abstract
The ability to predict male fertility is of paramount importance for animal breeding industries and for human reproduction. Conventional semen analysis generally provides information on the quantitative parameters of spermatozoa, but yields no information concerning its functional competence. Proteomics have identified candidates for male fertility biomarkers, but no studies have clearly identified the relationship between the proteome and sperm fertility. Therefore, we performed a proteomic analysis to investigate small and large litter size boar spermatozoa and identify proteins related to male fertility. In this study, 20 proteins showed differential expression levels in small and large litter size groups. Nineteen of these proteins exhibited decreased expression in large litter size samples and increased expression in the small litter group. Interestingly, only one protein was highly expressed in the large litter size spermatozoa. We then identified signaling pathways associated with the differentially expressed protein markers. Glutathione S-transferase Mu3 and glutathione peroxidase 4 were related to the glutathione metabolic pathway and arginine vasopressin receptor 2 was linked to vasopressin R2/STAT. In summary, this is the first study to consider negative fertility biomarkers, and the identified proteins could potentially be used as biomarkers for the detection of inferior male fertility.

Abstract
OBJECTIVE To determine whether seminal B7-H3 levels are correlated to semen parameters and affect human sperm functions. METHODS A total of 83 healthy donors of proven fertility (aged 22-37 years) and 176 infertile men (aged 21-38 years) were recruited. Computer-assisted semen analysis and enzyme-linked immunosorbent assay were used to assess the correlations between seminal B7-H3 levels and semen parameters. Flow cytometry and fluorescence microscopy were used to detect the putative receptor for B7-H3. Computer-assisted semen analysis and FITC-conjugated pisum sativum agglutinin staining were performed for assessing sperm motility, capacitation, and acrosome reaction (AR) after incubation with various concentrations of B7-H3 for 0-4 hours in vitro. RESULTS Seminal B7-H3 level was significantly higher in the healthy donors than that in the infertile men (P <.05), and closely associated with sperm concentrations and progressive motility (all P <.05), but not the other parameters examined (all P >.05). A putative receptor for B7-H3 was detected on the surface of sperm, with no significant differences in expression between the healthy donors and infertile men (P >.05). Seminal B7-H3 promoted sperm progressive motility in a time- and dose-dependent manner in vitro, although having no significant influence on sperm capacitation and AR. CONCLUSION B7-H3 showed a favorable effect on human sperm motility, without affecting sperm capacitation and AR.

Abstract
Heat shock protein 70 (HSP70) is a member of molecular chaperones and is important for reproductive biological processes in eukaryotes. In this regard, a full length HSP70 comprised of 2366 nucleotides from the red claw crayfish Cherax quadricarinatus (CqHSP70) was characterized, which with an open-reading frame of 1959 bp encoded 652 amino acid residues. Its mRNA transcript expression in the testes was measured by real-time quantitative PCR. CqHSP70 mRNA transcripts were detected in all organs especially high in the testes. Furthermore, the greatest transcript levels were found during the spermatogonial preparation phase, while the lowest levels were found during the resting stage of the reproductive cycle. In addition, its distribution in the testes was determined by Western blot and immunohistochemistry. Western blot results revealed a single immunoreactive band with an estimated molecular mass of 70 kDa in different phases of testes development. The strongest immunolabeling positive signal was found in spermatogonia, with lower positive staining in secondary spermatocytes, and weak or absent level in the mature sperm. Interestingly, CqHSP70 was mainly located in the cytoplasm of sperm cells. Thus, our results indicate that CqHSP70 is an essential protein in spermatogenesis, with a crucial reproductive function during sperm maturation in invertebrates.

Abstract
Emergence of chronic inflammation in the urogenital tract induced by Chlamydia trachomatis infection in females is a long-standing concern. To avoid the severe sequelae of C. trachomatis infection, such as pelvic inflammatory diseases (PID), ectopic pregnancies, and tubal infertility, antibiotic strategies aim to eradicate the pathogen even in asymptomatic and uncomplicated infections. Although first-line antimicrobials have proven successful for the treatment of C. trachomatis infection, treatment failures have been observed in a notable number of cases. Due to the obligate intracellular growth of C. trachomatis, reliable antimicrobial susceptibility assays have to consider environmental conditions and host cell-specific factors. Oxygen concentrations in the female urogenital tract are physiologically low and decrease further during an inflammatory process. We compared MIC testing and time-kill curves (TKC) for doxycycline, azithromycin, rifampin, and moxifloxacin under hypoxia (2% O2) and normoxia (20% O2). While low oxygen availability only moderately decreased the antichlamydial activity of azithromycin in conventional MIC testing (0.08 μg/ml versus 0.04 μg/ml; P<0.05), TKC analyses revealed profound divergences for antibiotic efficacies between the two conditions. Thus, C. trachomatis was significantly less rapidly killed by doxycycline and azithromycin under hypoxia, whereas the efficacies of moxifloxacin and rifampin remained unaffected using concentrations at therapeutic serum levels. Chemical inhibition of multidrug resistance protein 1 (MDR-1), but not multidrug resistance-associated protein 1 (MRP-1), restored doxycycline activity against intracellular C. trachomatis under hypoxia. We suggest careful consideration of tissue-specific characteristics, including oxygen availability, when testing antimicrobial activities of antibiotics against intracellular bacteria.

METHOD OF STUDY Semen samples from 80 men attending an andrologic clinic were evaluated to determine the presence of leukocyte, bacteria, antibodies against Chlamydia trachomatis, levels of IL-6, IL-8, IL-10, and TNF-alpha, HSP-60, anti-HSP-60 antibodies, and anti-sperm antibodies. RESULTS Leukocytes in semen significantly correlated with an increase in IL-6, IL-8, and TNF-alpha. The simultaneous presence of pathogens and leukocytes was associated with high levels of IL-8 and TNF-alpha, whereas IL-6 was more associated with the presence of leukocytes. Anti-HSP-60 antibodies positively correlated with IL-6 and IL-8. The presence of anti-sperm antibodies highly associated with an increase in anti-HSP-60 antibodies. CONCLUSIONS The type of cytokines present in the semen will depend on the single or simultaneous presence of leukocytes and/or pathogens. Chronic male genital tract infections could be associated with the development of anti-HSP-60 antibodies and anti-sperm antibodies.

[PMID: 19482415 DOI: 10.1016/j.eururo.2009.05.015] [Citation(s) in RCA: 59] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2009] [Accepted: 05/06/2009] [Indexed: 12/13/2022]
Abstract
BACKGROUND The impact of chronic prostatitis resulting from Chlamydia trachomatis infection on male fertility is controversial. OBJECTIVE To investigate the correlation between C. trachomatis infection and semen quality in young male patients affected by chronic prostatitis resulting from C. trachomatis infection and to evaluate the correlation between anti-C. trachomatis immunoglobulin (Ig) A against heat shock protein 60 (HSP60), heat shock protein 70 (HSP70), and semen parameters. DESIGN, SETTING, AND PARTICIPANTS All patients with clinical and instrumental diagnosis of chronic prostatitis underwent microbiological cultures for common bacteria, DNA extraction, mucosal and serum antibody evaluation for C. trachomatis, and semen parameter analysis. Western blot analysis of mucosal anti-C. trachomatis IgA was performed. INTERVENTIONS Subjects were split into two groups: Group A consisted of patients with chronic prostatitis resulting from common bacteria (uropathogens), and group B consisted of patients with chronic prostatitis resulting from C. trachomatis infection. MEASUREMENTS The relationship between C. trachomatis infection and semen parameters as well as the correlation among IgA levels, IgA characterisation, and semen analysis were determined. RESULTS AND LIMITATIONS We enrolled 1161 patients (mean age: 36.5 yr). Of these, 707 patients were placed in group A, and 454 were placed in group B. Significant statistical differences were reported between groups in terms of sperm concentration (p<0.001), percentage of motile sperm (p<0.001), and normal morphologic forms (p<0.001). Strong correlations between mucosal anti-C. trachomatis IgA and sperm concentration (p<0.001) and normal morphologic forms (p<0.001) were reported. Correlations among positivity to HSP60, HSP70, and sperm concentration (p<0.003) and normal morphologic forms (p<0.001) were also reported. CONCLUSIONS This study demonstrated the role of chronic prostatitis resulting from C. trachomatis in male fertility decrease, highlighting probable immunomediated damage to germinal cells because of C. trachomatis infections.

Abstract
OBJECTIVE To identify Chlamydia trachomatis DNA by polymerase chain reaction in the upper genital tract of men with obstructive azoospermia compared with men seeking vasectomy reversal. DESIGN Case-control study. SETTING Tertiary referral center, Aberdeen Royal Infirmary, Aberdeen, United Kingdom. PATIENT(S) Cases were men with idiopathic obstructive azoospermia, and controls were men with azoospermia secondary to vasectomy. INTERVENTION(S) Chlamydia trachomatis-specific DNA test by polymerase chain reaction on testicular and epididymal biopsy samples, as well as epididymal aspirate. MAIN OUTCOME MEASURE(S) Presence of Chlamydia trachomatis DNA. RESULT(S) We did not detect the presence of Chlamydia trachomatis-specific DNA by polymerase chain reaction in the epididymis or testis of 36 asymptomatic men with obstructive azoospermia (14 cases, 22 controls). CONCLUSION(S) Our hypothesis that unrecognized, asymptomatic chlamydial infection will lead to complete bilateral obstruction of the male genital tract remains unproven.

Abstract
Aim: Antisperm antibodies (ASA) in males cause the autoimmune disease 'immune infertility'. The present study intended to detect the presence of ASA and their incidence in men with unexplained infertility, as well as to evaluate the correlation between the presence of ASA and semen parameter alterations. Methods: Blood and sperm assessment were collected to carry out a direct and indirect mixed antiglobulin reaction (MAR) test and semen analysis in infertile and fertile men from the University Hospital of the Faculty of Medicine, Sao Paulo State University, Sao Paulo. Results: In the MAR test, 18.18% of infertile men were positive for ASA. In fertile men, no positivity was found. A significant correlation between the presence of ASA with an increased white blood cell count plus a decreased hypoosmotic swelling test result was observed. Conclusions: The results indicate that ASA are involved in reduced fertility. It is not ASA detection per se that provides conclusive information about the occurrence of damage to fertility. The correlation between infertility and altered seminal parameters reinforce the ASA participation in this pathology. (Reprod Med Biol 2007; 6: 33-38).

Abstract
PROBLEM Establishing the correlation between antichlamydial antibodies (AchAbs) and antisperm antibodies (ASA) in patients with chlamydial infections. METHOD OF STUDY ASA were studied in sera from patients (142 with genital, 57 with ocular chlamydial infections) and control group (n = 100) by gelatin and tray agglutination test (TAT), sperm immobilization test (SIT) and ELISA. AchAbs were revealed by ELISA. RESULTS A significantly higher (P < 0.05) ASA incidence was noted in patients with genital infections as compared with controls and patients with ophthalmologic infection (P < 0.0001), but not between patients with ophthalmologic infection and controls (P > 0.05). A significant correlation was established between AchAbs and ASA for TAT (r = 0.8214, P = 0.0341), SIT (r = 0.797, P = 0.032) and ELISA (r = 0.8519, P = 0.0313) in patients with genital infections only. CONCLUSIONS The genital Chlamydia infection may play a role in the induction of ASA. This is probably a result of the inflammatory process, but not of cross-reactivity between sperm and Chlamydia trachomatis antigens.

Abstract
PROBLEM To assess the association between antibodies to Chlamydia trachomatis heat shock proteins 60 and 10 (Hsp60 and Hsp10) and subfertility in a general population sample. METHOD OF STUDY A nested case (n = 146)-control (n = 278) study in a population-based birth cohort. Serum immunoglobulin (Ig)G and IgA antibodies against C. trachomatis Hsp60 and Hsp10, explanatory factors, were measured by enzyme immunoassay, using recombinant proteins as antigens. The main outcome variable was subfertility (time to pregnancy > or =12 months). RESULTS The prevalence and medians of serum IgA antibodies to Hsp60 and Hsp10 were significantly higher in the female partners of subfertile couple than in their fertile controls. On the contrary, among male partners of subfertile couple, especially among smokers serum antibody levels to Hsp antigens were lower than in the controls. CONCLUSION The results indicate a serological association of antibodies to chlamydial Hsp antigens with female subfertility in a population-based sample.

Abstract
Heat shock protein 70 (HSP70) is part of a superfamily of molecular chaperones, which protect cells from chemical and heat shock. The objectives of this study were to determine the presence of HSP70 in bovine spermatozoa and its subcellular localization during different stages of spermatogenesis. Analysis of sperm proteins by Western blotting using a monoclonal antibody to the inducible form of HSP70 revealed a single immunoreactive band with an estimated molecular weight of 70 kDa in samples from 18 of 18 bulls. Using immunofluorescence microscopy and the same antibody, HSP70 was localized to the cytoplasm of prophase spermatocytes and elongating spermatids, to cytoplasmic droplets of caput epididymal spermatozoa, and to cytoplasmic droplets, acrosome, post-acrosomal region and middle piece of corpus and cauda epididymal spermatozoa. The pattern of distribution changed in freshly ejaculated spermatozoa as HSP70 was detected on the acrosome only. During capacitation and acrosome reaction, HSP70 was once again redistributed, and was localized to the equatorial segment, post-acrosomal region and middle piece. Thus, HSP70 is present in the spermatozoa of mature bulls and redistribution of the protein occurs during capacitation and the acrosome reaction.

Abstract
With approximately 90 million cases annually, infection with Chlamydia trachomatis is the most prevalent sexually transmitted bacterial disease in the world. Considering that these infections are often asymptomatic and cause major complications like acute pelvic inflammatory disease, ectopic pregnancy, infertility or infant pneumonia, the estimated costs for diagnosis and treatment in the USA amounts to 2.2 million US dollars for each 500 cases. Therefore, there is a high need for correct, quick and cost-effective diagnosis and treatment of this urogenital tract infection. New innovative therapies provide good results with regard to efficacy and patients' compliance. The success rates of treatments are at least 95%. However, the occurrence of antibiotic resistance should not be ignored and new treatment schemes must be developed. The state-of-the-art of diagnosis and treatment of chlamydial infections as well as the pathophysiology is discussed in this review. In conclusion, infections with C. trachomatis is an important public health problem, especially in third world and developing countries, and more socio-economic studies linking secondary prevention of chlamydial infections, infertility and adverse pregnancy outcome are needed to understand more of its aetiology. In addition, diagnosis and treatment should be improved. Data in men revealed that past infections but not present infections are more related to male infertility. There is still controversial results. In future studies, function of the seminal vesicles and evaluation of the antioxidant capacity should be taken into account when role of C. trachomatis infection on male fertility is assessed.

Abstract
Diagnostic potential of the Chlamydia trachomatis ligase chain reaction system (LCx) to assess the presence of C. trachomatis in urine and semen specimens was evaluated. Paired urine and semen specimens from 153 asymptomatic male partners of subfertile couples attending our Center for Reproductive Medicine were examined by LCx. As controls, 19 semen samples from four donors who were participating in the programme for artificial insemination were used. Of these, 12 samples had previously been shown to be C. trachomatis-positive by an in-house PCR. C. trachomatis was detected by LCx in seven of 153 (5 %) urine samples. None of the 153 semen samples tested positive by LCx. Also, none of the 12 C. trachomatis-containing control semen samples were positive by LCx. By in-house PCR, seven urine specimens and two of 153 (1 %) semen samples tested positive. The corresponding urine samples of these male partners were also C. trachomatis-positive, as well as the 12 C. trachomatis-containing samples from donors. In conclusion, LCx is not sensitive enough to assess the presence of C. trachomatis in semen specimens; therefore, this method is not recommended to routinely screen semen specimens from donors who participate in programmes for artificial insemination or male partners of subfertile couples for C. trachomatis.
