High prevalence of urogenital infection/inflammation in patients with azoospermia does not impede surgical sperm retrieval.

Considering infection/inflammation to be an important risk factor in male infertility, the aim of this study was to make a comprehensive evaluation of the prevalence of urogenital tract infection/inflammation and its potential impact on sperm retrieval in azoospermic patients. In this prospective study, 71 patients with azoospermia were subjected to an extensive andrological workup including comprehensive microbiological diagnostics (2-glass test, semen, testicular swab and testicular tissue analysis) and testicular biopsy/testicular sperm extraction (TESE). Medical history suggested urogenital tract infection/inflammation in 7% of patients, 11% harboured STIs, 14% showed significant bacteriospermia, 15% had seminal inflammation, 17% fulfilled the MAGI definition, and 27% had relevant pathogens. At the testicular level, 1 patient had a swab positive for bacteria, no viruses were detected, tissue specimens never indicated pathogens, whereas histopathology revealed focal immune cell infiltrates in 23% of samples. Testicular sperm retrieval rate was 100% in obstructive and 46% in nonobstructive azoospermia. None of the infection/inflammation-related variables was associated with the success of sperm retrieval or inflammatory lesions in the testis. The high prevalence of urogenital infection/inflammation among azoospermic men underpins their role as significant aetiologic factors in male infertility. However, this observation does not refer to the chances of sperm retrieval at the time of surgery/TESE.

Hormonal treatment with transdermal testosterone in patients with male accessory gland inflammation (MAGI): Effects on sperm parameters.

Recently, it has been reported that treatment with testosterone (T) could have favourable effects on prostate inflammation; however, the data appear inconsistent. The main evidences concern experimental studies, and there is lower information obtainable from clinical studies. This study was conducted on patients with diagnosis of male accessory gland infection (MAGI) and a concomitant hormonal condition of acquired hypergonadotropic hypogonadism and has evaluated the effects on sperm parameters of the administration of a transdermal formulation of T gel for 3 months. The treated patients showed a significantly increased percentage of spermatozoa with normal form and progressive motility (p < .05 vs baseline), a significant reduction of CD45pos leucocytes in the semen (p < .05 vs baseline) and finally a significant increase of the seminal concentrations of zinc, fructose and alpha-glucosidase (p < .05 vs baseline) identified as key parameters associated to secretory function of the male accessory glands. The results of this study suggest the use of transdermal T in hypogonadal patients with MAGI for favourable effects on sperm parameters.

Beneficial Effects of the Very-Low-Calorie Ketogenic Diet on the Symptoms of Male Accessory Gland Inflammation.

Introduction. Obesity exposes individuals to the risk of chronic inflammation of the prostate gland. Aim and design of the study. A longitudinal clinical study was conducted on selected overweight/obese patients with male accessory gland inflammation (MAGI) to evaluate the effects of body weight loss on their urogenital symptoms. Materials and methods. One hundred patients were selected and assigned to two groups undergoing two different nutritional programs. The first group (n = 50) started a Mediterranean diet (MedDiet) and the second (n = 50) a very-low-calorie ketogenic diet (VLCKD). Before and after three months on the diet, each patient was evaluated for body weight, waist circumference, and MAGI symptoms. The MAGI was assessed using the Structured Interview about MAGI (SI-MAGI), a questionnaire previously designed to assess the symptoms of MAGI. The questionnaire explores four domains, including urinary symptoms, ejaculatory pain or discomfort, sexual dysfunction, and impaired quality of life. Finally, in the two groups, the frequency of an α-blocker used to treat urinary tract symptoms was also evaluated. Results. Patients on MedDiet experienced significant amelioration in urinary symptoms and quality of life. Patients under VLCKD reported not only significant improvement of the same parameters, but also in ejaculatory pain/discomfort and sexual dysfunction. Finally, the percentage of patients on VLCKD taking the α-blocker decreased significantly. Moreover, patients under VLCKD showed a greater loss of body weight than those following the MedDiet. Discussion. The results of this study support the effectiveness of VLCKD in improving the symptoms of patients with MAGI. This improvement involved all of the domains of the SI-MAGI questionnaire and became manifest in a relatively short time. We suggest that a ketogenic nutritional approach can be used in overweight/obese patients with MAGI.

Identification of seminal markers of male accessory gland inflammation: From molecules to proteome.

Male accessory gland infection/inflammation (MAGI) is a frequent disease, mostly with a chronic course, involving 1 or more sexual accessory glands. Majority of the MAGIs remain asymptomatic, thereby leading to a dilemma whether to treat these patients or not. It is moreover noteworthy that the diagnosis of MAGI is difficult, since patients are frequently asymptomatic and semen samples or prostatic secretions are often free from bacteria. As a consequence the identification of novel and reliable markers of inflammation in seminal plasma is an open challenge. If leukocytospermia and polymorphonuclear elastase and the analysis of the secretory products of male accessory glands have been widely used in the past, their diagnostic significance is discussed. Some cytokines (IL-6 and IL-8) and protein markers (suPAR) have been reported in the last years as the most promising markers for the diagnosis and the follow-up of MAGI. Recent advances in proteomic techniques undoubtedly represent a real promise in the future for the identification of novel markers of MAGI. This article provides an overview of key seminal biomarkers of MAGI, including the novel perspectives of the putative markers deriving by the most recent proteomic approaches.

Hyperestrogenism and low serum testosterone-17ß-estradiol ratio are associated with non-bacterial male accessory gland inflammation.

This study evaluated the serum concentrations of the main sex hormones in selected patients with non-bacterial male accessory gland infection (MAGI). The results suggest that the mean serum concentrations of 17ß-estradiol (method : chemiluminescence) in these patients are significantly higher compared to the controls (55.0 ± 15.0 vs. 26.5 ± 12.0 pg/mL; P <0.05) and the percentage of patients with MAGI and associated hyperestrogenism (according to the laboratory range used in this study) was significantly higher (25.00% vs. 3.00%; P <0.05). Moreover, the percentage of patients with non-bacterial MAGI and associated testosterone deficiency (serum total testosterone <2.49 ng/mL) was significantly higher (18.00% vs. 2.00%; P <0.05). Finally, patients with non-bacterial MAGI showed a significantly lower total testosterone-17ß-estradiol ratio compared to the controls (72.7 vs. 173.0; P <0.05). The results of this study, with some limitations (in particular the method applied for the determination of serum concentrations of 17ß-estradiol) represent in our opinion, a topic worthy of further investigation for a correct endocrinological characterization of these patients, useful for clinical practice.

Soluble urokinase-type plasminogen activator receptor as a putative marker of male accessory gland inflammation.

UNLABELLED: The association between male accessory gland infection/inflammation (MAGI) and infertility is well-known in clinical practice. Standard semen analysis, leukocytospermia, and microbiological tests are often not enough accurate for a diagnosis. A large amount of biochemical parameters in seminal plasma have been suggested as inflammation markers, however, there is not yet a sensitive and specific biomarker that accurately identifies MAGI. We investigated the presence of soluble urokinase-type plasminogen activator receptor (suPAR), known marker of systemic inflammation, in the seminal plasma to evaluate its possible involvement in urogenital tract inflammation. On the basis of andrological evaluation, including spermiogram and ultrasound findings, we selected 76 patients with MAGI and 30 healthy men as control group. Patients were classified according to the results of the semen culture in group A (n = 28) presenting a bacterial MAGI and group B (n = 48) with abacterial MAGI. C-reactive protein (CRP), total protein (TP), procalcitonin (PCT), leukocytes peroxidase (LP), and suPAR concentrations were assayed on seminal plasma. Spermiogram parameters were significantly lower in the patients with MAGI than in controls. CRP, TP, PCT, and LP did not differ in MAGI vs. CONTROLS: suPAR was detectable in all semen samples; it was significantly increased in A and B groups (86.6 ± 30.7 ng/mL vs. 39.7 ± 17.2 ng/mL) with an inverse correlation with sperm parameters. We selected by receiver operating characteristic curve a suPAR cut-off value of 55.3 ng/mL as a diagnostic threshold for the diagnosis of MAGI. We report in this study the first evidence of suPAR presence in seminal plasma, focusing on its interesting role as reliable and sensitive marker of inflammation for the differential diagnosis of MAGI.
