Abstract
Bladder dysfunction, particularly neurogenic detrusor overactivity (DO), poses a substantial challenge in multiple sclerosis (MS) patients, detrimentally impacting their quality of life (QoL). Conventional therapies often fall short, necessitating alternative approaches like posterior tibial nerve stimulation (PTNS) for effective management. This narrative review critically examines the application of PTNS in treating DO among MS patients, aiming to provide a comprehensive synthesis of its efficacy, underlying mechanisms, and clinical outcomes. By evaluating a spectrum of studies, including randomized controlled trials and long-term follow-up research, the review elucidates PTNS's role in enhancing bladder control and ameliorating symptoms of urgency and incontinence, thereby improving patient well-being. Despite its potential, the review acknowledges the limited scope of existing research specific to MS-induced neurogenic DO and calls for further investigation to optimize PTNS protocols and understand its long-term benefits. Highlighting PTNS's minimal invasiveness and favorable safety profile, the review advocates for its consideration as a viable third-line treatment option in MS-related bladder dysfunction management. Through this analysis, the review contributes to the broader narrative of seeking effective, patient-centered therapeutic strategies for MS-related complications, underscoring the importance of personalized care in improving patient outcomes.

Abstract
This study investigates the impact of pelvic floor muscle training (PFMT) on sexual function and distress in women with multiple sclerosis (MS), a prevalent chronic nervous system disorder associated with sexual dysfunction. This study's primary aim was to assess the effectiveness of PFMT at improving sexual function and alleviating sexual distress in this population. In a randomised controlled trial, 82 women with MS were divided into two groups: Group A (41 women) underwent 12 weeks of PFMT, while Group B (41 women) served as a control group with no intervention. Both groups were assessed at the beginning and end of this study using the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R). Statistical analysis, including Chi-square tests, was employed to compare the outcomes between the two groups, with a p-value of less than 0.05 considered significant. The results revealed no significant differences in baseline sexual function and distress between the groups. However, at the conclusion of the 12-week period, Group A exhibited statistically significant improvements in nearly all domains of FSFI and FSDS-R compared to Group B, except in the pain domain. This study concludes that PFMT can effectively enhance sexual function and reduce sexual distress in women suffering from MS. These findings underscore the potential of PFMT as a therapeutic intervention in managing sexual dysfunction associated with MS.

Abstract
Benign prostatic hyperplasia (BPH), a prevalent condition in older men, is often managed through various surgical interventions. This narrative review aims to explore the impact of these surgical treatments on sexual function, a critical aspect of patient quality of life often overlooked in BPH management. The methodology encompassed a thorough review of contemporary surgical techniques for BPH, including prostate resection, enucleation, vaporization, and minimally invasive therapies such as UroLift, Rezum, and Aquablation. Additionally, the focus was on patient-centered outcomes, with a special emphasis on sexual health following surgery. Findings reveal that, while surgical interventions effectively alleviate BPH symptoms, they often have significant repercussions in sexual function, including erectile and ejaculatory dysfunction. However, emerging techniques demonstrate potential in preserving sexual function, underscoring the need for patient-centric treatment approaches. The study highlights the complex interplay between BPH surgery and sexual health, with minimally invasive treatments showing promise in balancing symptom relief and sexual function preservation. In conclusion, the study advocates for an integrated, interdisciplinary approach to BPH treatment, emphasizing the importance of considering sexual health in therapeutic decision-making. This narrative review suggests a paradigm shift towards minimally invasive techniques could optimize patient outcomes, marrying symptom relief with quality-of-life considerations. The need for further research in this domain is evident, particularly in understanding long-term sexual health outcomes following different surgical interventions for BPH.

Abstract
Acquired hemophilia A (AHA) is a rare autoimmune disorder marked by autoantibodies against coagulation factor VIII, leading to bleeding complications. This case report explores a unique presentation of AHA, initially manifested as gross hematuria, a symptom often encountered in healthcare settings with a broad range of differential diagnoses. The background of this study highlights the rarity of AHA and its diverse clinical presentations. The case involves a 62-year-old man with no history of bleeding disorders, presenting with gross hematuria and later developing severe anemia and ecchymoses. Methods employed in the evaluation included urological assessments such as cystoscopy and computed tomography, alongside hematological investigations, which later revealed a prolonged activated partial thromboplastin time (aPTT) and a critically low factor VIII level, indicative of AHA. Results showed a lack of early recognition of coagulation abnormalities, underscoring the need for comprehensive initial assessments in cases of unexplained hematuria. The patient's management at a specialized Hemophilia Center involved inhibitor eradication therapy and management of acute bleeding episodes, resulting in significant clinical improvement. The conclusions drawn from this case emphasize the importance of considering rare conditions like AHA in the differential diagnosis of hematuria and the necessity for a broad diagnostic approach. It advocates for heightened awareness and early coagulation studies in unexplained cases of hematuria to prevent delayed diagnoses and improve patient outcomes. This case contributes to the understanding of AHA's clinical variability and the critical nature of early and comprehensive diagnostic approaches in hematuria evaluation.

Abstract
Infertility is a global health concern, with male factors playing an especially large role. Unfortunately, however, the contributions made by reproductive urologists in managing male infertility under assisted reproductive technology (ART) often go undervalued. This narrative review highlights the important role played by reproductive urologists in diagnosing and treating male infertility as well as any barriers they face when providing services. This manuscript presents a comprehensive review of reproductive urologists' role in managing male infertility, outlining their expertise in diagnosing and managing male infertility as well as reversible causes and performing surgical techniques such as sperm retrieval. This manuscript investigates the barriers limiting urologist involvement such as limited availability, awareness among healthcare professionals, and financial constraints. This study highlights a decrease in male fertility due to lifestyle factors like sedentary behavior, obesity, and substance abuse. It stresses the significance of conducting an evaluation process involving both male and female partners to identify any underlying factors contributing to infertility and to identify patients who do not require any interventions beyond ART. We conclude that engaging urologists more effectively in infertility management is key to optimizing fertility outcomes among couples undergoing assisted reproductive technology treatments and requires greater education among healthcare providers regarding the role urologists and lifestyle factors that could have an effect on male fertility.

Abstract
The human microbiota in the genital tract is pivotal for maintaining fertility, but its disruption can lead to male infertility. This study examines the relationship between microbial dysbiosis and male infertility, underscoring the promise of precision medicine in this field. Through a comprehensive review, this research indicates microbial signatures associated with male infertility, such as altered bacterial diversity, the dominance of pathogenic species, and imbalances in the genital microbiome. Key mechanisms linking microbial dysbiosis to infertility include inflammation, oxidative stress, and sperm structural deterioration. Emerging strategies like targeted antimicrobial therapies, probiotics, prebiotics, and fecal microbiota transplantation have shown potential in adjusting the genital microbiota to enhance male fertility. Notably, the application of precision medicine, which customizes treatments based on individual microbial profiles and specific causes of infertility, emerges as a promising approach to enhance treatment outcomes. Ultimately, microbial dysbiosis is intricately linked to male infertility, and embracing personalized treatment strategies rooted in precision medicine principles could be the way forward in addressing infertility associated with microbial factors.

Abstract
Oxidative stress is a significant factor in male infertility, compromising sperm function and overall reproductive health. As male infertility garners increasing attention, effective therapeutic interventions become paramount. This review investigates the therapeutic role of antioxidants in addressing male infertility. A detailed examination was conducted on antioxidants such as vitamin C, E, B12, D, coenzyme Q10, zinc, folic acid, selenium, l-carnitine, l-arginine, inositols, and alpha-lipoic acid. This analysis examines the methodologies, outcomes, and constraints of current clinical studies. Antioxidants show notable potential in counteracting the negative effects of oxidative stress on sperm. Based on the evidence, these antioxidants, individually or synergistically, can enhance sperm health and reproductive outcomes. However, certain limitations in the studies call for careful interpretation. Antioxidants are integral in tackling male infertility attributed to oxidative stress. The current findings underscore their therapeutic value, yet there's a pressing need for deeper, comprehensive research. Future studies should focus on refining dosage guidelines, identifying potential side effects, and discerning the most efficacious antioxidant combinations for male infertility solutions.

Abstract
Several reports have been published during the last decade studying the effect of pelvic floor muscle training (PFMT) in treating urinary incontinence and sexual dysfunction in multiple sclerosis (MS) patients. The aim of the current study is to bring up-to-date findings of earlier systematic reviews, taking into account data published up till June 2023. Databases such as PubMed, Scopus, and EBSCOhost were screened for randomized controlled studies, clinical trials, and systematic reviews. The keywords for the current review were MS, urinary incontinence, sexual function, and PFMT. The implementation of predetermined eligibility criteria permitted an appropriate and convenient study selection. English language publications alone were considered. After removing duplicates and screening the initially recovered articles, an initial search within the present review identified 19 studies. Finally, 10 randomized control trials and two systematic reviews were eligible for evaluation and included in the current review. The outcome measures were the severity of incontinence or overactive bladder, leakage episodes, sexual dysfunction, health-related quality of life, and adherence to PFMT. PFMT is a convenient and effective treatment tool that can significantly improve health-related quality of life and reduce the severity of urinary incontinence and overactive bladder symptoms in people with MS. The present review confirms the effectiveness of specific exercises on leakage episodes, pad usage, sexual dysfunction, compliance to treatment, and treatment satisfaction. Further research is needed to strengthen the reported results.

Abstract
BACKGROUND Non-obstructive azoospermia (NOA) presents a challenge in male infertility management. This study aimed to assess the efficacy of diagnostic testicular biopsy (DTB) in predicting sperm retrieval success via therapeutic testicular biopsy (TTB) and to understand the role of systemic inflammation in microdissection testicular sperm extraction (mTESE) outcomes. METHODS A retrospective analysis was conducted on 50 NOA males who underwent mTESE at the University of Ioannina's Department of Urology from January 2017 to December 2019. All participants underwent thorough medical evaluations, including semen analyses and endocrinological assessments. RESULTS DTB did not detect spermatozoa in half of the patients who later showed positive sperm findings in TTB. Preoperative variables, such as age, plasma levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), prolactin (PRL), estradiol (E2), and inflammation biomarkers (neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-eosinophil ratio (MER)), were not consistently predictive of sperm retrieval success. Notably, TTB-negative patients had elevated NLR and PLR values, suggesting a possible link between systemic inflammation and reduced sperm retrieval during mTESE. CONCLUSIONS The findings question the necessity of an initial DTB, which might provide misleading results. A negative DTB should not deter further TTB or intracytoplasmic sperm injection (ICSI) attempts. The study emphasizes the need for further research to refine diagnostic approaches and deepen the understanding of factors influencing sperm retrieval in NOA patients, ultimately enhancing their prospects of biological parenthood.

Abstract
Post-hypospadias repair, hair growth within the urethra, and subsequent hair bezoar formation can lead to significant complications, including urinary tract infections (UTIs) and urinary flow obstruction. Using hair-bearing skin in hypospadias repair can cause these complications. We report a 55-year-old male who underwent two-stage penile hypospadias repair at age three, presenting with recurrent UTIs and lower urinary tract obstruction symptoms. Urethroscopy identified a hair bezoar in a wide-mouth diverticulum of the penile urethra. Post-extraction of the hair bezoar using a rigid cystoscope, transcutaneous neodymium-doped yttrium aluminum garnet (ND:YAG) laser epilation was employed to ablate urethral diverticular hair follicles. Hair bezoars in the urethra, although rare in modern practice, may obstruct urine flow and act as a nidus for UTIs. Transcutaneous ND:YAG laser has emerged as a minimally invasive technique, offering a simple, effective solution for urethral hair removal with minimal complications. Transcutaneous ND:YAG laser epilation serves as a viable first-line treatment for urethral hair follicles following hypospadias repair, emphasizing its significance in preventing recurrent complications in such patients.

Abstract
Oxidative stress (OS), which arises through an imbalance between the formation of reactive oxygen species (ROS) and antioxidant defenses, plays a key role in the pathophysiology of female infertility, with the latter constituting just one of a number of diseases linked to OS as a potential cause. The aim of the present article is to review the literature regarding the association between OS and female infertility. Among the reproductive diseases considered are endometriosis and polycystic ovary syndrome (PCOS), while environmental pollutants, lifestyle variables, and underlying medical conditions possibly resulting in OS are additionally examined. Current evidence points to OS likely contributing to the pathophysiology of the above reproductive disorders, with the amount of damage done by OS being influenced by such variables as duration and severity of exposure and the individual's age and genetic predisposition. Also discussed are the processes via which OS may affect female fertility, these including DNA damage and mitochondrial dysfunction. Finally, the last section of the manuscript contains an evaluation of treatment options, including antioxidants and lifestyle modification, capable of minimizing OS in infertile women. The prime message underlined by this review is the importance of considering OS in the diagnosis and treatment of female infertility. Further studies are, nevertheless required to identify the best treatment regimen and its ideal duration.

Abstract
Coronavirus disease 19 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), jeopardizes male fertility because of the vulnerability of the male reproductive system, especially the testes. This study evaluates the effects of the virus on testicular function and examines the potential role of antioxidants in mitigating the damage caused by oxidative stress (OS). A comprehensive PubMed search examined exocrine and endocrine testicular function alteration, the interplay between OS and COVID-19-induced defects, and the potential benefit of antioxidants. Although the virus is rarely directly detectable in sperm and testicular tissue, semen quality and hormonal balance are affected in patients, with some changes persisting throughout a spermatogenesis cycle. Testicular pathology in deceased patients shows defects in spermatogenesis, vascular changes, and inflammation. Acute primary hypogonadism is observed mainly in severely infected cases. Elevated OS and sperm DNA fragmentation markers suggest redox imbalance as a possible mechanism behind the fertility changes. COVID-19 vaccines appear to be safe for male fertility, but the efficacy of antioxidants to improve sperm quality after infection remains unproven due to limited research. Given the limited and inconclusive evidence, careful evaluation of men recovering from COVID-19 seeking fertility improvement is strongly recommended.

Abstract
Age-related mitochondrial markers may facilitate the prognosis of artificial reproductive technology outcomes. In this report, we present our study concerning the ratio of cf-mtDNA/cf-nDNA, namely the amount of cell-free mitochondrial DNA relative to cell-free nuclear DNA, in the follicular fluid (FF) of women undergoing IVF, aiming to generate a molecular fingerprint of oocyte quality. The values of this ratio were measured and compared among three groups of women (101 in total): (A) 31 women with polycystic ovary syndrome (PCOS), (B) 34 women younger than 36 years, and (C) 36 women older than 35 years of age. Real-time quantitative PCR (qPCR) was performed to quantify the ratio by using nuclear- and mitochondrial-specific primers and analyzed for potential correlation with age and pregnancy rate. Our analysis showed that the level of FF-cf-mtDNA was lower in the group of advanced-age women than in the groups of PCOS and non-PCOS women. Moreover, a significant positive correlation between FF-cf-mtDNA and the number of mature (MII) oocytes was observed. Collectively, the data show that the relative ratio of cf- mtDNA to cf-nDNA content in human FF can be an effective predictor for assessing the corresponding oocyte's age-related performance in IVF.

Abstract
While conventional lipomas represent the most commonly seen benign mesenchymal tumor in adults, their occurrence in the bladder wall is exceptionally rare. This report details a rare case of a bladder lipoma, a benign tumor primarily composed of mature adipocytes, presenting as gross hematuria in a 68-year-old male. Despite the patient's previous history of left nephrectomy, no significant pathological findings were initially observed. The bladder lipoma was detected via cystoscopy as a polypoid mass on the posterior bladder wall and confirmed through transurethral resection of the bladder tumor (TUR-BT). Histopathological analysis verified the mass as a bladder lipoma composed of mature adipocytes. Following a specific postoperative follow-up period, no recurrence of the tumor was observed, suggesting successful treatment. This case underscores the clinical significance of considering bladder lipoma in differential diagnoses of bladder tumors, especially in patients presenting with gross hematuria, given its exceptional rarity.

Abstract
Paraganglioma of the urinary bladder is an exceptionally rare tumor. It originates from chromaffin cells, which are responsible for producing catecholamines. We report a unique case of a 74-year-old woman diagnosed with nonfunctional bladder paraganglioma, who presented with macroscopic hematuria and right-sided renal colic but lacked the usual symptoms associated with catecholamine excess. This case highlights the diagnostic challenges of nonfunctional variants of paraganglioma due to their histological similarity to urothelial carcinomas. It underscores the importance of a thorough histological examination and the need for a multidisciplinary approach to establish a diagnosis and determine the optimal treatment strategy. Our case contributes to the sparse literature on this rare condition, and it aims to enhance clinicians' awareness and understanding of urinary bladder paragangliomas.

Abstract
The average age of fathers at first pregnancy has risen significantly over the last decade owing to various variables, including a longer life expectancy, more access to contraception, later marriage, and other factors. As has been proven in several studies, women over 35 years of age have an increased risk of infertility, pregnancy problems, spontaneous abortion, congenital malformations, and postnatal issues. There are varying opinions on whether a father's age affects the quality of his sperm or his ability to father a child. First, there is no single accepted definition of old age in a father. Second, much research has reported contradictory findings in the literature, particularly concerning the most frequently examined criteria. Increasing evidence suggests that the father's age contributes to his offspring's higher vulnerability to inheritable diseases. Our comprehensive literature evaluation shows a direct correlation between paternal age and decreased sperm quality and testicular function. Genetic abnormalities, such as DNA mutations and chromosomal aneuploidies, and epigenetic modifications, such as the silencing of essential genes, have all been linked to the father's advancing years. Paternal age has been shown to affect reproductive and fertility outcomes, such as the success rate of in vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI), and premature birth rate. Several diseases, including autism, schizophrenia, bipolar disorders, and paediatric leukaemia, have been linked to the father's advanced years. Therefore, informing infertile couples of the alarming correlations between older fathers and a rise in their offspring's diseases is crucial, so that they can be effectively guided through their reproductive years.

Abstract
BACKGROUND Varicocele represents the most common correctable cause of male infertility. The presence of non-invasive imaging parameters providing evidence as to which patients with varicocele are at risk for infertility would be important. PURPOSE To explore the role of dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) using semi-quantitative parameters in the assessment of testicular perfusion in infertile men with clinical varicocele. MATERIAL AND METHODS The study cohort included 11 infertile men with clinical varicocele and six controls, with prior paternity. Subtraction DCE-MRI was performed after gadolinium administration, using a three-dimensional fast field-echo sequence. Time-signal intensity curves were created and semi-quantitative parameters were calculated. The independent samples t-test was used to compare basic T1 perfusion parameters between infertile testes with clinical varicocele and normal testes. Logistic regression analysis was performed to assess the most significant predictor of the diagnosis of clinical varicocele. RESULTS Both testes with clinical varicocele and normal testes enhanced moderately and homogeneously, with a linear increase of enhancement throughout the examination. Higher mean values of maximum enhancement (P = 0.026), maximum relative enhancement (P = 0.024), and wash-in rate (P = 0.013) were detected in the testes of infertile men with clinical varicocele, compared to the normal population. The wash-in rate proved the most significant predictor of the diagnosis of clinical varicocele (P = 0.013). CONCLUSION DCE-MRI may provide a valuable insight into the testicular perfusion of infertile men with clinical varicocele. The wash-in rate proved a strong and independent predictor of the diagnosis of clinical varicocele.

The objective of this review study is to evaluate the therapeutic role of PDE5 inhibitors (PDE5is) in the amelioration of oligoasthenospermia in infertile males. PDE5is have a beneficial influence on the secretory function of the Leydig and Sertoli cells, the biochemical environment within the seminiferous tubule, the contractility of the testicular tunica albuginea, and the prostatic secretory function. In several studies, the overall effect of sildenafil and vardenafil increased quantitative and qualitative sperm motility. Furthermore, some studies indicate that PDE5is influence positively the sperm capacity to undergo capacitation under biochemical conditions that are known to induce the sperm capacitation process. Additional research efforts are necessary in order to recommend unequivocally the usage of sildenafil, vardenafil, or avanafil for the alleviation of male infertility.

Abstract
Purpose Clean intermittent self-catheterization (CISC) is a safe and effective alternative to managing incomplete bladder emptying in patients afflicted with neurogenic bladder conditions. The Intermittent Catheterisation Difficulty Questionnaire (ICDQ) is a validated questionnaire concerning the assessment of catheter use and patient difficulties during CISC. The present study aimed to translate and validate the ICDQ into the Greek language. A subsequent outcome was to substantiate the requirement of both urologist consultation with patients undergoing CISC and the detailed evaluation of various therapeutic options with the consultation of other specialist physicians. Material and Methods The study was undertaken between March 2022 and July 2022 and involved patients in an outpatient department of a Rehabilitation Centre. Sixty-two neurologic patients suffering from spinal cord injury (SCI), multiple sclerosis (MS), cauda equina (CE), and myelitis represented a convenience sample. To calculate test-retest reliability, patients filled out two consecutive questionnaires; an initial one and a second after one week. The socio and demographic circumstances of all participants were evaluated. Results The mean ICDQ total score at the test and retest was 5.96±1.28 (mean total score ± standard deviation) and 5.91±1.29, respectively. Evaluation of the data concerning alterations between men and women did not reveal statistically significant differences. Cronbach’s alpha coefficient was 0.94, which proves the inter-correlation between the different topics. An ICC of 0.97 indicated very high intra-rater reliability. Conclusion ICDQ, a valid and reliable self-administered screening tool for CISC difficulties faced by patients using this procedure regularly, was successfully translated and validated into Greek. A more detailed evaluation and understanding of these difficulties would enhance the quality of CISC and allow for more suitable treatment and the selection of catheter types used. These improved treatment strategies are possible as repeated use and constant comparison of ICDQ scores determine treatment impact, facilitating treatment regimen modification, should it be required.

Abstract
Purpose Coronavirus disease (COVID-19) is a multi-organ viral infection with many manifestations. However, its impact on the genitourinary system is nowadays under investigation. This study aimed to evaluate the consequences on bladder function in patients suffering from post-acute COVID-19 syndrome (PACS) transferred to inpatient rehabilitation for long-term care after initial treatment for COVID-19 pathophysiology. Materials and Methods All the patients were initially asked the question (after having recovered from the acute stage of COVID-19 disease): “Have you noticed a sudden, uncontrolled need to urinate and sometimes a urine leakage accompanying the voiding desire?” Sixty-six out of 147 patients responded positively to this question and were assessed with the AUA Urology Care Foundation Overactive Bladder Assessment Tool (AUA-OAB-tool). All included men were evaluated with the IPSS score. Results The median age of patients was 59.5 (range 44–72). We identified 44 patients with newly diagnosed OAB (Group A; post-COVID assessment) and 22 with worsening OAB symptoms (Group B). The mean symptom score ± standard deviation in Group A patients was 18.25 ± 2.11 (using the above AUA OAB tool). In the patients of Group B, there was an increase in the above score from 10.43 ± 1.52 (pre-COVID condition) to 17.87 ± 1.89 (post-COVID assessment). In patients of Group A, the total quality of life (QOL) score was 17.74 ± 2.34. Patients in Group B presented an escalation in total QOL score from 9.04 ± 1.41 (pre-COVID) to 18.84 ± 1.96 (post-COVID condition). There was no statistically significant difference in symptoms and QOL scores between men and women in groups A and B. There were 11 men in Group A and 5 in Group B with an IPSS score >20. Conclusion OAB symptoms may be essential to PACS syndrome and influence quality of life, delaying full recovery.

Abstract
The knowledge on male reproduction is constantly expanding, especially in treating infertility due to non-obstructive azoospermia (NOA). Varicocele is occasionally diagnosed in a subpopulation of males with NOA. Varicocele repair in NOA-men may contribute to the reappearance of spermatozoa in semen. However, spontaneous pregnancies are observed in only a small percentage of NOA-men post-varicocelectomy. Additionally, it has been reported that the repair of varicocele in NOA-men (before the performance of sperm retrieval techniques) may increase the testicular sperm recovery rate. In addition, it increases the pregnancy rate in intracytoplasmic sperm injection (ICSI) programs in NOA-men without spermatozoa in the semen post-varicocelectomy. In addition, to the improvement in Sertoli cellular secretory function, varicocelectomy may increase the secretory function of Leydig cells, which subsequently results in improved androgen production, raising the probability to negate the need for testosterone replacement therapy in cases of late-onset hypogonadism. On the other hand, the benefit of varicocelectomy in patients with NOA is still debatable. The current review study aims to provide a critical and extensive review of varicocele repair in males with NOA. This study additionally focuses on the impact of varicocele repair on sperm retrieval rates and its influence on the ICSI outcomes for those couples who remain negative for spermatozoa in their semen samples post-varicocelectomy.

Abstract
BACKGROUND & OBJECTIVE Significant advances in the field of male infertility have been witnessed during the last years. Given the well-known detrimental effects of reactive oxygen species (ROS), the administration of antioxidants has emerged as a promising solution for oxidative stress (OS)-induced male infertility. Nevertheless, this perception seems largely oversimplified, and the existing literature fails to recognize a notable superiority of the excessive use of these widely available nutritional compounds. Taking into consideration that several trials have shed light on the so-called "antioxidant paradox" phenomenon, we recognize that over-the-counter consumption of such supplements might be harmful. METHODS The relevant studies indexed in PubMed, Google Scholar and Scopus databases, published until September 2019 were identified and reported. CONCLUSION In this setting, we acknowledge that there is an urgent need for more elaborate studies in the future that will efficiently elucidate the risks and benefits of antioxidants on semen parameters and their impact on fertility potential.

Abstract
The therapeutic range of cyclic nucleotide phosphodiesterase 5 inhibitors (PDE5) inhibitors is getting
wider in the last years. This review study focuses on the potential employment of PDE5 inhibitors as an adjunct
tool for the therapeutic management of male infertility. The literature tends to suggest a beneficial effect of PDE5
inhibitors on Leydig and Sertoli cells secretory function. It also appears that PDE5 inhibitors play a role in the
regulation of the contractility of the testicular tunica albuginea and the epididymis. Moreover, scientific data
suggest that PDE5 inhibitors enhance the prostatic secretory function leading to an improvement in sperm motility.
Other studies additionally demonstrate the role of PDE5 inhibitors in the regulation of the sperm capacitation
process. Placebo-controlled, randomized, blind studies are necessary to unambiguously incorporate PDE5 inhibitors
as an adjunct tool for the pharmaceutical treatment of semen disorders and male infertility.

Abstract
BACKGROUND Despite the limited evidence about the effect of micronutrient supplementation on the semen quality, many micronutrient supplements have been used to improve male fertility. Approximately, 40%- 50% of male infertility cases in general and up to 80% in men with idiopathic infertility cases are caused by oxidative stress and decreased level of seminal total antioxidant capacity. OBJECTIVE To investigate the beneficial effects of micronutrient supplementation on sperm concentration, motility and morphology. METHODS A PubMed, Google Scholar, Embase data, Web of Science and Cochrane Library database extensive research of the randomized controlled studies utilizing micronutrient vitamins and supplements was performed. RESULTS The existent international literature is rather heterogeneous and a definitive is difficult to be drawn. Several micronutrients have beneficial effects on sperm parameters. Rational use of micronutrients might be helpful for infertile patients. CONCLUSION Further randomized, controlled clinical trials are required to elucidate the efficacy and safety of micronutrients and propose proper protocols for their use. A well-rounded, balanced diet is more preferable than the widespread use of micronutrient supplements beyond the recommended doses. Future studies should concern the pregnancy rate as a primary outcome in their designs. Further research should be done to determine the appropriate antioxidant compounds, the duration of the treatment, as well as a certain dose of antioxidants in clinical practices. The pre-treatment evaluation of the seminal oxidative status is also an important parameter to proceed with micronutrient supplementation without the risk of reductive stress. Under these conditions, supplements could support the quality of sperm and help to alleviate male infertility.

Abstract
BACKGROUND Testicular magnetic resonance imaging parameters, including apparent diffusion coefficient, fractional anisotropy, magnetization transfer ratio, and normalized metabolite concentrations represent useful noninvasive fingerprints of nonobstructive azoospermia. Nonobstructive azoospermia etiology might correlate with the spermatogenesis status. OBJECTIVES To assess the possible association between apparent diffusion coefficient, fractional anisotropy, magnetization transfer ratio, and normalised metabolite concentrations with nonobstructive azoospermia etiology. MATERIALS AND METHODS This retrospective study included 48 consecutive men with nonobstructive azoospermia and 18 age-matched controls. All participants underwent scrotal magnetic resonance imaging. The testicular apparent diffusion coefficient, fractional anisotropy, magnetization transfer ratio, and normalized metabolite concentrations were calculated. nonobstructive azoospermia men were classified into three groups, based on etiology: group 1, idiopathic; group 2, genetic causes; and group 3, non-genetic causes. Parametric and nonparametric statistical tests were used to evaluate differences in magnetic resonance imaging parameters between nonobstructive azoospermia groups and normal testes (group 4). Regression analysis was performed to assess the most predictive magnetic resonance imaging factor of nonobstructive azoospermia etiology. RESULTS Differences in mean apparent diffusion coefficient (p < .001), fractional anisotropy (p < .001), magnetization transfer ratio (p < .001), and normalized concentrations of total choline (p = .005), glucose (p = .012), myo-inositol (p = .024), and lipids (p = .010) were observed among groups. Regression analysis failed to identify the most discriminating magnetic resonance imaging feature for nonobstructive azoospermia etiology. DISCUSSION AND CONCLUSION Apparent diffusion coefficient, fractional anisotropy, magnetization transfer ratio, and normalized concentrations of total choline, glucose, myo-inositol, and lipids are helpful in discriminating nonobstructive azoospermia etiology. Magnetic resonance imaging may provide useful, noninvasive information on the microstructural and biochemical milieu of nonobstructive azoospermia testes.

Abstract
Purpose The present study aimed to translate the Targeting the individual's Aetiology of Nocturia to Guide Outcomes Questionnaire (TANGO) into the Greek language to create TANGO-Gr. A relative reliability study in prospective samples of community dwellers and rehabilitation centre residents was undertaken in order to validate the translation. In terms of nocturia severity, these groups were considered to be representative of patients at both ends of the scale, and therefore suitable validation purposes. Patients and Methods The prospective descriptive study took place between 07 and 09/2020. Fifty residents in a rehabilitation centre and thirty-seven community dwellers were included in the study. All participants had more than one episode of nocturia per night. They were asked to complete the newly translated TANGO-Gr Questionnaire twice (test-retest procedure). TANGO-Gr includes three possible answers ("yes", "no", and "DK/NA") to facilitate increased validity. The study group evaluated the socio and demographic characteristics, the level of independence and the comprehensive frailty of all participants. Results Both groups satisfactorily completed questionnaire responses. The overall Cronbach's alpha coefficient was 0.753 (community-dwelling people: 0.776; rehabilitation centre residents: 0.531). A test-retest statistical analysis to determine reliability found an overall median Kappa of 0.88 (IQR: 0.79-0.94) in community dwellers and 0.91 (IQR: 0.84-1.00) in rehabilitation centre residents, thereby confirming an almost perfect respective agreement. Conclusion The validity of the newly translated TANGO-Gr Questionnaire was proven. It should be considered to be a reliable, self-administered screening tool suitable for clinical practice, and therefore invaluable for Greek-speaking people. The study also determined that certain environment-related variables may contribute to nocturia in rehabilitation centre populations, which is a finding which invites further study.

Abstract
Purpose Older people, especially women, have the highest known prevalence of urinary incontinence (UI) of any other age-group. Continual care provision for elderly incontinent females is an incredibly arduous process, yet only very few studies have investigated the issue. Aim of the study was to evaluate the impact of mirabegron’s treatment on the degree of burden experienced by caregivers of elderly female patients with UI. Patients and Methods A hundred and eighty-six caregivers of older females with mixed or urgency UI besides various conditions (strokes, post-operative recovery after major surgery, etc.) were included in the study. Group A comprised 91 patients that did not want to receive any treatment for UI. Group B consisted of 95 elderly females treated for UI with mirabegron 50 mg/daily for three months. All caregivers completed the Zarit Burden Scale (ZBS) questionnaire at the outset and after the three months. All patients completed a bladder diary at the beginning and at the end of the observation/medication period. Results Patients receiving mirabegron presented a statistically significant improvement in UI parameters. Their caregivers showed a statistically significant decrease in the ZBS total score as well as separate domains. Conclusion This pilot study confirms that mirabegron administration can improve the quality of life of older females suffering from UI while substantially relieving caregiver burden. Recognizing the physical and emotional reactions of caregivers may help health providers deliver better support and resources to meet the needs of caregivers and patients alike.

Abstract
BACKGROUND Bladder leiomyomas are rare and benign tumors of the bladder. They account for 0.43% of all bladder tumors, and only 250 cases have been reported in English literature. Based on the size and localization of the lesion, their symptoms vary considerably. Women seem to be more affected, and obstructive symptoms predominate. Surgical treatment is almost always highly effective, leaving a low recurrence rate. CASE PRESENTATION We present a clinical case of a 52-year old man with macroscopic hematuria and obstructive lower urinary tract symptoms due to a large bladder trigone leiomyoma. CT and MRI showed a well-defined large bladder leiomyoma and cystoscopy established the initial findings. The patient underwent successful transurethral resection of the lesion, and pathology findings confirmed the diagnosis. CONCLUSIONS This case report demonstrates that transurethral resection of a large bladder trigone leiomyoma is a feasible and successful procedure. Long term follow-up proves that there is neither scarring distortion of the bladder trigone area nor damage in the ureteral orifices, even though there was a thorough removal of the trigone wall.

Abstract
PURPOSE To evaluate the potential of prostate cancer detection on the basis of prostate-specific antigen (PSA)-level and percent free PSA (% fPSA) according to the outcome of prostate needle biopsy. METHODS This was a retrospective study of 1040 patients that underwent a prostate biopsy in the Urologic Clinic of the University Hospital of Ioannina, Greece. The patients underwent needle biopsy after abnormal finding in digital rectal examination (DRE). Tissue samples were extracted using a 12-core TRUS-GB. The patients were divided into four groups according to the biopsy outcome. Total serum and free PSA were measured. RESULTS The mean PSA concentration of cancer versus noncancer groups was significantly higher (p<0.05). The positive predictive value (PPV) of PSA for serum concentration >10 ng/ml was 47% while the negative predictive value (NPV) in patients with PSA levels <4 ng/ml was 81%. The diagnostic accuracy of % fPSA for patients with PSA level between 4-10 ng/ml was 0.651 (95% CI, 0.549-0.754) (p<0.05). A statistically significant difference in mean PSA concentration was recorded between prostate cancers classified as grade 2 (3+4=7) and 3 (4+3=7) and grade 4 (8) and 5 (9-10) (p<0.05). CONCLUSIONS Though informative and suggestive, PSA and % fPSA are not definitive for cancer or non-cancer determination. The differentiation of PSA level between tumours classified as grade 2 (3+4=7) and grade 3 (4+3=7) could support the determination of treatment by backing pathologist's interpretation of the histological diagnosis.

Abstract
Mycobacterium marinum is a photochromogenic mycobacterium that is ubiquitous in the aquatic environment. In the general population, exposure to aquaria is the most common cause of M. marinum infection. Known as "swimmer's granuloma" or "fish tank granuloma," M. marinum is an occupational hazard for aquarium cleaners and fishermen. There are several reports in the literature of M. marinum infection in immunocompromised hosts, including those with solid organ transplants, but none in patients who have received stem cell transplants (SCTs). To our knowledge, this is a first report of disseminated M. marinum infection in an SCT recipient who continued to develop new skin lesions even after months of targeted therapy. The implications are that elderly patients who receive T-cell-depleted SCTs may be at prolonged risk for pathogens dependent on cellular immunity, and the presentation of illness with such pathogens may be more severe and widely disseminated than might otherwise be expected.
