Abstract
The male factor contributes approximately 50% to infertility-related cases in couples with an estimated 12%–35% of these cases attributable to male genital tract infections. Depending on the nature of the infection, testicular sperm production, sperm transport, and sperm function can be compromised. Yet, infections are potentially treatable causes of infertility. Male genital tract infections are increasingly difficult to detect. Moreover, they often remain asymptomatic (“silent”) with the result that they are then passed on to the relevant sexual partner leading to fertilization and pregnancy failure as well as illness of the offspring. With the worldwide increasing problem of antibiotic resistance of pathogens, proper diagnosis and therapy of the patient is important. This testing, however, should include not only aerobic microbes but also anaerobic as these can be found in almost all ejaculates with about 71% being potentially pathogenic. Therefore, in cases of any indication of a male genital tract infection, a semen culture should be carried out, particularly in patients with questionable semen quality. Globally, an estimate of 340 million new infections with sexually transmitted pathogens is recorded annually. Among these, the most prevalent pathogens including Chlamydia trachomatis, Ureaplasma urealyticum, Neisseria gonorrhoeae, and Mycoplasma hominis. Escherichia coli are considered the most common nonsexually transmitted urogenital tract microbes. These pathogens cause epididymitis, epididymo-orchitis, or prostatitis and contribute to increased seminal leukocyte concentrations.

Bacteriospermia and Its Impact on Basic Semen Parameters among Infertile Men. Interdiscip Perspect Infect Dis 2016; 2016:2614692. [PMID: 26880908 PMCID: PMC4736773 DOI: 10.1155/2016/2614692] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2015] [Revised: 12/15/2015] [Accepted: 12/20/2015] [Indexed: 11/18/2022] Open
Abstract
Introduction. Semen analysis is considered as the surrogate marker for male fecundity while assessing infertile men. There are several reasons for altered semen quality and bacteriospermia could be one among them. Thereby the aim of our work is to study the semen culture and its impact on semen parameters among infertile men. Materials and Methods. Semen samples were collected from men attending infertility clinic. Semen parameters were analysed based on WHO guidelines. Also, samples were subjected to culture using standard bacteriological techniques. Results. A total of 85 samples were collected. A number of 47 (55.30%) had normal sperm count, 37 (43.50%) had oligozoospermia, and one (1.17%) had azoospermia. Teratozoospermia was the most common abnormality observed (81.17%) followed by asthenozoospermia (28.23%). The prevalence of bacteriospermia was 35.3%. Enterococcus faecalis (30%) was the most common organism isolated followed by Coagulase negative Staphylococcus (23.33%), Staphylococcus aureus (20%), and E. coli (10%). Other less frequently isolated organisms were Klebsiella pneumoniae (6.66%), Proteus sp. (6.66%), and Citrobacter sp. (3.33%). Conclusion. The presence of asymptomatic bacteriospermia did not correlate with abnormal semen parameters.

Abstract
OBJECTIVES This study evaluated the association between pus cells and semen parameters in infertile Pakistani males. METHODS A cross-sectional descriptive study was carried out in the Department of Reproductive Physiology/Health, National Institute of Health, Islamabad, Pakistan, from 2004 to 2009. A total of 1,521 subjects were analysed, along with 97 proven fathers as controls. RESULTS The mean of pus cells was 7.43 ± 0.43, 4.35 ± 0.34, and 4.26 ± 0.17 per high field in teratozoospermic, oligoasthenozoospermic, and asthenozoospermic groups, respectively, while it was 3.25 ± 0.26, 3.10 ± 0.19, and 2.98 ± 0.04 per high field in azoospermic, oligozoospermic and the proven father groups, respectively. The fewest pus cells were observed among proven fathers, which varied non-significantly (P >0.05) with all cases, except with teratozoospermic, oligozoospermic, and oligoasthenozoospermic cases. Pus cells showed an inverse relationship to sperm motility and count, except in azoospemia cases. Similarly, the fewest pus cells were observed among groups where normal forms where significantly more frequent (P <0.05). More pus cells were observed in cases where motility, and concentration or morphology was compromised. Similarly, low pus cell counts were seen in cases where sperm had the fewest head and neck defects. All kinds of sperm defects varied non-significantly (P >0.05) between proven fathers and normal concentration cases. CONCLUSION High pus cell counts were observed in various subclasses of infertile patients. Ignorance of this pyospermic factor will make pyospermic patients to be misdiagnosed as normozoospermic. Therefore, the presence of pyospermia must be considered by physicians as a male infertility factor.

Abstract
OBJECTIVE To determine the incidence of bacteriospermia and elevated seminal leukocytes (ESL) in a subfertile male population and correlate these results with semen parameters. DESIGN Retrospective cohort study. SETTING Canadian tertiary-level male infertility clinic and university-affiliated andrology and microbiology laboratories. PATIENT(S) Four thousand nine hundred thirty-five nonazoospermic subfertile men. INTERVENTION(S) Analysis and concurrent culture of 7,852 semen samples. MAIN OUTCOME MEASURE(S) Incidence of bacteriospermia and ESL and comparison of semen parameters between these groups. RESULT(S) The rate of bacteriospermia was 15% (22 species), and the rate of ESL was 19%, with no statistical correlation between these groups. Bacteriospermic patients (without ESL) had a statistically significant deterioration in DNA fragmentation index (DFI) only, compared with patients without bacteriospermia and ESL (24.1 vs. 21.8%). ESL alone was associated with a statistically significant deterioration in sperm concentration (20.6 vs. 55.3 × 10(6)/mL), motility (21.8 vs. 26.9%), normal morphology (12.3 vs. 17.4%), and DFI (26.5 vs. 21.8%), with no additional deterioration identified with bacteriospermia. CONCLUSION(S) Bacteriospermia and ESL were prevalent, but not statistically associated, in subfertile men. Bacteriospermia alone was associated with an increase in DFI only, but the presence of ESL was the dominant factor associated with deterioration in semen parameters.

Abstract
Prostatitis and infertility are common disorders in men and many researchers have investigated a possible link between the two disorders. After almost 3 decades of research the answer to this question remains unknown, although ample evidence exists to support a relationship between male infertility and prostatitis. This paper discusses this evidence and then derives a rational treatment approach to the man with infertility and prostatitis.

Abstract
OBJECTIVES An association between prostatitis and male infertility has been suspected, yet is poorly understood. Prostatitis is often associated with granulocytes in the prostatic fluid that generate reactive oxygen species (ROS), known to impair male fertility. We compared ROS, the total antioxidant capacity (TAC), and a novel index of oxidative stress (ROS-TAC score) in patients with chronic prostatitis and in healthy controls. METHODS Semen specimens from 36 men with chronic prostatitis (National Institutes of Health category IIIa), 8 men with prostatodynia (National Institutes of Health category IIIb), and 19 controls attending our urologic clinic were examined according to the World Health Organization criteria. Leukocytospermia was measured by the Endtz test (myeloperoxidase assay). ROS and TAC production was measured by chemiluminescence assay. A composite ROS-TAC score was also calculated in patients and controls. RESULTS The sperm concentration, percentage of motility, and morphology among the groups did not differ. The mean +/- standard error log-transformed ROS level was significantly higher in patients with leukocytospermia (3.2 +/- 0.6) than in patients without leukocytospermia (1.8 +/- 0.2; P = 0.04) and controls (1.3 +/- 0.3, P = 0.01). TAC was significantly lower in patients with or without leukocytospermia (859.69 +/- 193.0 and 914.9 +/- 65.2, respectively) than in controls (1653.98 +/- 93.6, P = 0.001). The mean ROS-TAC score of controls (50.0 +/- 4.1) was significantly higher than those of patients with chronic prostatitis and leukocytospermia (8.2 +/- 9.2) and those without leukocytospermia (34.2 +/- 2.9; P <0.001). CONCLUSIONS Men with chronic prostatitis or prostatodynia have seminal oxidative stress, irrespective of their leukocytospermia status. These observations may help shed light on the long-standing controversy surrounding prostatitis and infertility.

Abstract
Immunoinfertility is an important problem, involving a significant number of infertile couples. Although the presence of antibodies on sperm has better prognostic value than those in serum or seminal plasma, it may not be the sole authentic evidence of immunoinfertility. Infertility from antisperm antibodies is likely only when they bind to a relevant sperm antigen involved in a specific fertility function. The variance in functional deficits seen in immunologic infertility is most likely related to antibodies directed at different sperm antigens or different class, subclass, or isotypes. Antibodies to FA-1 seem to be of significant importance in human immunoinfertility. In approaching couples with infertility, a high index of suspicion for antibodies is necessary to avoid misdiagnosis. In the optimal situation, all semen analyses should be screened for sperm-bound antibodies, but if this is impractical, testing should be performed on high-risk individuals (Table I). In couples in which the man has sperm-bound antibodies, and in whom there is no identifiable female factor, treatment should be instituted. Most treatments for immunoinfertility have been disappointing because of poor results, adverse effects, or high cost. Corticosteroid therapy has shown some promise in published reports (mostly poorly designed studies), but increase in pregnancy rate is modest and adverse effects may be significant. In our opinion, informed consent should be documented prior to institution of corticosteroid therapy, and subjects should be closely monitored. Advanced reproductive technologies offer a higher safety profile, and, with increasing technology, higher pregnancy rates. We recommend progressing from "low-tech" procedures, such as IUI and reserving the higher level procedures, such as IVF and ICSI, for those couples in whom pregnancy does not occur. The highest level reproductive technologies give the best current prospects for pregnancy in patients with this difficult problem but also are invasive and costly. It is hoped that further work in the laboratory will give rise to newer, safer, and less expensive effective treatments in the very near future.

Abstract
OBJECTIVE To analyze the data available on the biologic significance of white blood cells (WBC) in semen of infertility patients. DATA RESOURCES The relevant literature was reviewed. RESULTS It is not possible to identify reliably WBC by conventional sperm staining techniques. The peroxidase method is sufficient for quantification of granulocytes, but immunocytology is the gold standard for the detection of all WBC populations in semen. Granulocytes are the most prevalent WBC type in semen (50% to 60%), followed by macrophages (20% to 30%) and T-lymphocytes (2% to 5%). The prevalence of leukocytospermia (> 10(6) WBC/mL semen) among male infertility patients is approximately 10% to 20%. There is controversy on the significance of WBC in semen. Whereas some authors did not observe sperm damage in the presence of leukocytospermia, others have found evidence that WBC are significant cofactors of male infertility: [1] seminal WBC numbers were higher in infertility patients than among fertile men; [2] leukocytospermia was associated with decreased sperm numbers and impaired sperm motility; [3] WBC damaged sperm function and hamster ovum penetration in vitro and were important prognostic factors for IVF-ET failure. Because of absence of clinical symptoms, the origin of WBC is difficult to determine. Normally, most WBC appear to originate from the epididymis because vasectomized men show very few WBC in semen. On the other hand, leukocytospermic samples show low citric acid levels, pointing to asymptomatic prostatitis as a source of WBC in semen. Surprisingly, approximately 80% of leukocytospermic samples are microbiologically negative. In some cases Chlamydia trachomatis might have triggered a persistent inflammatory reaction leading to leukocytospermia. Sperm damage by WBC can be mediated by reactive oxygen species, proteases and cytokines. Furthermore, genital tract inflammation facilitates the formation of sperm antibodies. As seminal plasma has strong anti-inflammatory properties and because there is only short contact between sperm and WBC in prostatitis and seminal vesiculitis, inflammations of the epididymis and testis are likely to have the largest impact on sperm. CONCLUSIONS There is ample evidence that WBC can affect sperm function. Further studies are needed to define cofactors that increase or decrease the risk of sperm damage by WBC.

Abstract
PROBLEM The prevalence of anti-sperm antibodies (ASAs) in the general population is 0 to 2%; the prevalence in infertile men is much higher at 7 to 26%. However, the role of ASAs in male infertility remains controversial to date. Although several risk factors for ASA development have been defined (such as testicular torsion, varicocele, cryptorchidism, vasectomy, and genital tract infection), there are no specific indications for ASA testing. METHOD In order to examine if a single parameter exists identifying patients with elevated ASA titers, serum ASA testing was performed with an enzyme-linked immunosorbent assay (ELISA) in 226 consecutive male patients. The new assay, synchron ELISA (Synelisa) used in our study represents a new type of ELISA without fixation of the sperm surface antigens by formaldehyde or glutaraldehyde. Therefore, the quantitative assay is highly sensitive and reproducible since the structure of sperm surface antigens is not altered by the fixation process. CONCLUSIONS The prevalence of ASAs in this population was 14%, while the prevalence of the control group was 2.5%. Of all factors analyzed only a history of vasectomy, an acute epididymitis, and an abnormal result in the bovine mucus penetration test was associated with elevated ASA titers (P < .001). In addition, we could demonstrate a time related formation of ASAs in men after vasectomy.

Abstract
The role of antisperm antibodies in human infertility remains controversial. Indications for antisperm antibody testing of male partners of infertile marriages have been based upon anecdotal reports and studies using outdated assays. In an effort to define the indications for antisperm antibody testing of the male partner, the immunobead assay for antisperm antibodies was performed upon 100 consecutive men referred for evaluation of male factor infertility. The prevalence of antisperm antibodies in this patient population was 18% and only 9% when patients with a history of vasectomy were excluded. Of all the factors analyzed, only a history of vasectomy and sperm agglutination on semen analysis were predictive of antisperm antibody status (p < 0.001). Use of the aforementioned parameters as an indication for antisperm antibody testing would have resulted in a sensitivity of 94%, specificity 73% and negative predictive value 98% in this patient population. The only way to identify all patients with significant levels of antisperm antibody activity (sensitivity 100%) would have been to test every patient.
