Role of oxidative stress in pathology of chronic prostatitis/chronic pelvic pain syndrome and male infertility and antioxidants function in ameliorating oxidative stress.

BACKGROUND: The relationship between chronic prostatitis and fertility has been controversial for many years. We have previously shown the presence of a cellular autoimmune response against prostate antigens in a group of chronic prostatitis patients. Our main goal was to investigate whether chronic prostatitis (either caused by an infection or an autoimmune response to the prostate gland) could have a deleterious effect on semen quality. METHODS: Forty-four patients diagnosed as suffering from chronic prostatitis were included and divided into groups according to the presence of infection and/or cellular autoimmune response against prostate antigens. Healthy normal individuals were included as controls. Measurements for sperm concentration, motility, morphology, prostate and seminal vesicle markers, antisperm antibodies, white blood cells and pro-inflammatory cytokines were performed accordingly. RESULTS: The most severe abnormalities were seen in patients with no evident infection and an autoimmune response against prostate antigens. Moreover, significantly increased levels of pro-inflammatory cytokines were detected in seminal plasma from these patients. CONCLUSIONS: This study shows that chronic prostatitis patients with cellular autoimmune response to prostate antigens present important alterations in their semen quality parameters. We speculate that an autoimmune response against prostate antigens and the inflammatory process involved may affect male fertility.

Reduced semen quality in chronic prostatitis patients that have cellular autoimmune response to prostate antigens

The role of urogenital inflammation in causing infertility and sexual dysfunctions has long been a matter of debate in the international scientific literature. The most recent scientific evidences show that male accessory gland infection/inflammation could alter, with various mechanisms, both conventional and biofunctional sperm parameters, and determine worst reproductive outcome. At the same time, the high prevalence of erectile dysfunction and premature ejaculation in patients with male accessory gland infection/inflammation underlines the close link between these diseases and sexual dysfunctions. The aim of this review was to provide the reader the basis for a correct diagnosis of male accessory gland infection/inflammation and a subsequent appropriate therapeutic approach, particularly in patients with infertility and/or sexual dysfunction.

Male accessory gland inflammation, infertility, and sexual dysfunctions: a practical approach to diagnosis and therapy.

Although it is widely considered, in many cases, to involve two separable stages (poor placentation followed by oxidative stress/inflammation), the precise originating causes of preeclampsia (PE) remain elusive. We have previously brought together some of the considerable evidence that a (dormant) microbial component is commonly a significant part of its etiology. However, apart from recognizing, consistent with this view, that the many inflammatory markers of PE are also increased in infection, we had little to say about immunity, whether innate or adaptive. In addition, we focused on the gut, oral and female urinary tract microbiomes as the main sources of the infection. We here marshall further evidence for an infectious component in PE, focusing on the immunological tolerance characteristic of pregnancy, and the well-established fact that increased exposure to the father's semen assists this immunological tolerance. As well as these benefits, however, semen is not sterile, microbial tolerance mechanisms may exist, and we also review the evidence that semen may be responsible for inoculating the developing conceptus (and maybe the placenta) with microbes, not all of which are benign. It is suggested that when they are not, this may be a significant cause of PE. A variety of epidemiological and other evidence is entirely consistent with this, not least correlations between semen infection, infertility and PE. Our view also leads to a series of other, testable predictions. Overall, we argue for a significant paternal role in the development of PE through microbial infection of the mother via insemination.

Immunological Tolerance, Pregnancy, and Preeclampsia: The Roles of Semen Microbes and the Father.

Background 
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the risk factors of impaired male fertility potential. Studies have investigated the effect of CP/CPPS on several semen parameters but have shown inconsistent results. Hence, we performed a systematic literature review and meta-analysis to assess the association between CP/CPPS and basic semen parameters in adult men.


Methods 
Systematic literature searches were conducted with PubMed, EMBASE and the Cochrane Library up to August 2013 for case-control studies that involved the impact of CP/CPSS on semen parameters. Meta-analysis was performed with Review Manager and Stata software. Standard mean differences (SMD) of semen parameters were identified with 95% confidence intervals (95% CI) in a random effects model.


Results 
Twelve studies were identified, including 999 cases of CP/CPPS and 455 controls. Our results illustrated that the sperm concentration and the percentage of progressively motile sperm and morphologically normal sperm from patients with CP/CPPS were significantly lower than controls (SMD (95% CI) −14.12 (−21.69, −6.63), −5.94 (−8.63, −3.25) and −8.26 (−11.83, −4.66), respectively). However, semen volume in the CP/CPPS group was higher than in the control group (SMD (95% CI) 0.50 (0.11, 0.89)). There was no significant effect of CP/CPPS on the total sperm count, sperm total motility, and sperm vitality.


Conclusions 
The present study illustrates that there was a significant negative effect of CP/CPPS on sperm concentration, sperm progressive motility, and normal sperm morphology. Further studies with larger sample sizes are needed to better illuminate the negative impact of CP/CPPS on semen parameters.

The Effect of Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) on Semen Parameters in Human Males: A Systematic Review and Meta-Analysis

The aim of this article was to discuss by means of a review of the literature and own study material the multifactorial aetiology of male infertility, extrapolate this hypothesis to male accessory gland infection (MAGI) and relate it to chronic prostatitis and its treatment. Infertility is a multifactorial disease and diagnosis and therapy must be oriented as such. Although the relationship between prostatitis and infertility remains unclear, bacteria, viruses, leucocytes, reactive oxygen species, cytokines, obstruction and immunological abnormalities must be seen as cofactors in the development of infertility in patients with MAGI and prostatitis. Infection, trauma, allergy, neurogenic damage, chemical or mechanical factors can lead to a long-lasting inflammation of the prostate or pelvic organs even after eradication of the aetiological agent, and is potentially related to infertility through cytokines. In relation to treatment of infertility, antibiotics play a role in bacterial prostatitis whereas in abacterial prostatitis other treatments like antioxidants, sacral nerve stimulation and anti-inflammatory treatment are worth to be studied in the future.
