Significant reduction in left testicular volume shown by ultrasonography in infertile patients with left-side grade 2-3 varicocele as compared to less than grade 2: An evidence for indication of varicocelectomy. Int J Urol 2024; 31:670-677. [PMID: 38402451 DOI: 10.1111/iju.15436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Accepted: 02/14/2024] [Indexed: 02/26/2024]
Abstract
PURPOSE Testicular volume (TV) is known to be one of the main parameters for testicular function (TF). This study was conducted to re-evaluate the indications of a varicocelectomy based on a survey of preoperative TV results in left-side varicocele patients considered to reflect the detrimental effects of a varicocele on TF. METHODS TV results of infertile patients determined using ultrasonography by a single expert physician were retrospectively evaluated. RESULTS Of 590 examined patients, 424 had no varicocele findings (Group A), while 148 had a left-side varicocele (Group B). Group B was subdivided based on varicocele grade into Group B0 (subclinical), B1 (grade 1), B2 (grade 2), and B3 (grade 3). Comparisons of left-side TV showed no significant differences for grade among Group A, B0, and B1, whereas that for Group B2 and B3 was significantly lower as compared with Group A (p < 0.01, 0.02, respectively). The median TV of Group B I (composed of Groups B0 and B1) was 9.8 cm3, while that of Group B II (Groups B2 and B3) was significantly lower at 8.4 cm3 (p < 0.05). In contrast, a comparison of right TV values identified no significant differences among the groups (p = 0.918). CONCLUSION A varicocelectomy should be performed for patients with a grade 2 and 3 varicocele for ameliorating testicular function.

Abstract
OBJECTIVE To evaluate the clinical efficacy of microscopic internal spermatic-inferior epigastric vein anastomosis in the treatment of left varicocele and compare it with microscopic spermatic vein ligation for the same condition. METHODS A retrospective analysis of 74 patients with left varicocele between July 2020 and July 2022 was performed. The patients were divided into two groups based on the surgical method used. Group A consisted of 37 patients who underwent microscopic internal spermatic-inferior epigastric vein anastomosis, while Group B consisted of 37 patients who underwent microscopic spermatic vein ligation. Comparison of preoperative and postoperative semen quality, reproductive hormone levels, scrotal ultrasound results, duration of surgery, length of hospital stay, postoperative recurrence rate, and occurrence of complications with a follow-up time of 12 mo between two groups. RESULTS Both groups showed significant improvements in semen quality and serum reproductive hormone levels. The Group A demonstrated significantly improved sperm forward motility compared to Group B, but had longer operation times and hospital stays (P < 0.05). After 1 year of follow-up, 8 partners in Group A and 6 partners in Group B achieved natural conception, with no significant difference between the two groups. There were no recurrences observed in either group during the follow-up period, and no significant statistical differences were found in other postoperative observation indicators. CONCLUSIONS Both microscopic internal spermatic-inferior epigastric vein anastomosis and microscopic spermatic vein ligation are effective surgical methods for treating left varicocele. Anastomosis surgery provides greater improvement in sperm motility, although it is associated with longer operation times and hospital stays.

Abstract
Varicoceles are a common condition affecting up to 15% of men in the general population, and up to 40% of men with infertility. A varicocele is an abnormal dilation of the veins within the scrotum, which can lead to reduced sperm production and testicular damage, resulting in infertility. Despite the prevalence of varicoceles, much remains to be discovered about their diagnosis, treatment, and long-term impact. Varicoceles are considered the 'holy grail' of Andrology because they represent a complex, multifactorial condition that requires a comprehensive approach to diagnosis and treatment. While surgical repair of varicoceles has been shown to improve fertility outcomes in some cases, there is still debate about the best approach to diagnosis and treatment, and long-term outcomes are not well understood. Advances in diagnostic imaging, such as color Doppler ultrasound, have improved our ability to identify varicoceles, but more research is needed to fully understand the impact of this condition on male fertility and overall health. As such, varicoceles represent an ongoing area of investigation in Andrology with much progress to be made in terms of diagnosis, treatment, and long-term impact.

Abstract
INTRODUCTION Varicocele is a condition in which the veins in the spermatic cord become enlarged and twisted. Varicocele is widely recognized as the leading cause of male infertility due to its significant impact on reproductive health in men. The aim of this study was to investigate the relationship between the diameter of the varicose vein and the recovery rate of the spermogram after varicocelectomy. Also, the effect of body mass index (BMI) on sperm parameters after varicocelectomy. METHODS This descriptive and analytical cross-sectional study was conducted in Valiasr Hospital's urology clinic in Qaemshahr, Iran from August 2018 to August 2019 and involved 27 men with unilateral left varicocele who met the inclusion criteria for surgical repair. Before the operation, we recorded demographic information, the maximum diameter of varicose veins in the pampiniform plexus, and spermogram results. We repeated semen analysis 3 months after the operation and analyzed the data using Statistical Package for the Social Sciences version 21 software. RESULTS Our findings showed that the diameter of the varicose vein before varicocelectomy was not significantly associated with the improvement of main semen parameters after the operation. Furthermore, our study suggested that a lower body mass index might contribute to a greater improvement in sperm motility, as individuals with lower BMI showed more significant improvement. DISCUSSION There is a significant inverse relationship between BMI and sperm motility improvement after surgery. Patients with a lower BMI showed greater improvement in sperm motility.

Abstract
Male-factor infertility is implicated in over half of the millions of cases of infertility worldwide, and varicoceles are the most common correctable cause of male-factor infertility. The pathophysiologic mechanism for varicoceles is complex and next-generation technologies offer promising insights into the molecular underpinnings of this condition. In this narrative review, we highlight historical and contemporary paradigms associated with varicoceles, with an emphasis on the biological underpinnings of this disease. Specifically, we review the literature describing the underlying causes of varicoceles, discuss the molecular and cellular mechanisms causing pathological changes in some (but not all) men, and highlight key articles regarding the next-generation analyses (e.g., transcriptome, epigenome, proteome, and microbiome) being applied to better understand the condition and its treatment. These data demonstrate an ongoing evolution of the knowledge of varicoceles and the potential for improved personalized care in the future for men with this condition.

Abstract
Pelvic congestion syndrome (PCS) in females and varicoceles in males may be regarded as closely related conditions since the main pathophysiological cause for both processes is pelvic venous insufficiency. Varicoceles are more prevalent amongst sub-fertile males, with an approximate incidence of 15% in the general male population. PCS is commonly diagnosed amongst premenopausal multiparous women, representing one of the leading causes of chronic pelvic pain. Both conditions appear to be predominantly left-sided and are associated with oxidative stress and pro-inflammatory cascades with subsequent effects on fertility. Clinical examination and pelvic ultrasonography play an essential role in the assessment of varicoceles, PCS and chronic pelvic pain. Venography is generally considered as a gold-standard procedure for both conditions. There is still much debate on how these conditions should be managed. This review article provides a comparative analysis of the underlying pathophysiological mechanisms of both PCS and varicoceles, their impact on fertility, as well as their clinical management.

Abstract
Varicocele is a major cause of male infertility. However, few studies have discussed the potential associations between the pain caused by varicocele and preoperative and intraoperative factors. The aim of this study was to evaluate factors potentially associated with changes in pain score after microsurgical varicocelectomy. This retrospective study was conducted between August 2020 and August 2022 at China Medical University Hospital in Taichung, Taiwan. Patient characteristics including age, body mass index, semen analysis, testicular volume, and the number of veins ligated were collected. Preoperative and intraoperative factors were analyzed to determine if they were correlated with changes in numeric rating scale (NRS) after microsurgical varicocelectomy. A total of 44 patients with clinical varicocele underwent subinguinal microsurgical varicocelectomy and were analyzed. The overall pain resolution rate was 91%, and the average satisfaction score after surgery was 9.2 according to their subjective feelings. Multivariate analysis revealed that severe varicocele grade (odds ratio [OR] 16.5, 95% confidence interval [CI] 3.01-90.47; P = .018) and the number of veins ligated (OR 6, 95% CI 1.6-22.48; P = .013), were significantly associated with changes in NRS after surgery. In addition, the area under the receiver operating characteristic curve for changes in NRS and the total number of veins ligated was 0.869. Microsurgical varicocelectomy had a high success rate for scrotal pain and satisfaction. Severe varicocele grade and the number of veins ligated in microsurgical varicocelectomy were associated with postoperative pain improvement.

Abstract
Intragastric balloons (IGBs) are commonly used for weight loss by mechanically distending the stomach. We present a case of a 35-year-old man who developed a left-sided varicocele 1 week after IGB insertion. Imaging revealed splenic vein compression and possible thrombosis. Urgent removal of the balloon was performed. After 1 week from removal, the patient showed significant improvement, with complete splenic vein recanalization. This case highlights the importance of early recognition of a rare complication of IGBs to avoid severe outcomes. To our knowledge, this is the first reported case linking IGBs to splenic vein compression and varicocele.

Abstract
Background: Male contraceptive approaches besides tubal sterilization involve vasectomy and represent the method of choice among midlife men in developing countries thanks to many advantages. However, the subsidiary consequences of this intervention are insufficiently explored since the involved mechanisms may offer insight into a much more complex picture. Methods: Thus, in this manuscript, we aimed to reunite all available data by searching three separate academic database(s) (PubMed, Web of Knowledge, and Scopus) published in the past two decades by covering the interval 2000–2023 and using a predefined set of keywords and strings involving “oxidative stress” (OS), “inflammation”, and “semen microbiota” in combination with “humans”, “rats”, and “mice”. Results: By following all evidence that fits in the pre-, post-, and vasectomy reversal (VR) stages, we identified a total of n = 210 studies from which only n = 21 were finally included following two procedures of eligibility evaluation. Conclusions: The topic surrounding this intricate landscape has created debate since the current evidence is contradictory, limited, or does not exist. Starting from this consideration, we argue that further research is mandatory to decipher how a vasectomy might disturb homeostasis.

Abstract
Varicocele is a frequently encountered urological disorder, which has a prevalence rate of 8 to 15% among healthy men. However, the incidence is higher in male patients with primary or secondary infertility, with up to 35 to 80% of varicocele cases occurring in this population. The clinical manifestations of varicocele typically include the presence of an asymptomatic mass that feels like a “bag of worms”, chronic scrotal pain, and infertility. Most patients with varicocele only undergo varicocelectomy after conservative treatments have failed. Unfortunately, some patients may still experience persistent scrotal pain due to a recurrence of varicocele, the development of hydrocele, neuralgia, referred pain, ureteral lesions, or nutcracker syndrome. Therefore, clinicians should consider these conditions as potential causes of postoperative scrotal pain, and take measures to address them. Several factors can assist in predicting surgical outcomes for patients with varicocele. Clinicians should consider these factors when deciding whether to perform surgery and what type of surgical intervention to use. By doing so, they can increase the likelihood of a successful surgical outcome and minimize the risk of complications such as postoperative scrotal pain.

Eligible patients were allocated by the investigators in a 1:1 ratio to receive intraoperative Doppler (group I) or intraoperative Doppler plus hydrodissection (group II). RESULTS Sixty men were included in each group. The two study groups showed a comparable number of ligated veins on the right (4.22 ±1.57 versus 4.42 ± 1.65; p = 0.49) and left side (6.77 ± 2.14 versus 6.98 ± 2.29; p = 0.59). On the contrary, group II showed a significantly higher number of preserved arteries on the right (2.42 ± 0.56 versus 1.47 ±0.5 in group I) and left side (2.6 ± 0.53 versus 1.63 ± 0.55 in group I), with p-value < 0.001. The sperm motility was significantly higher in group II than in group I (21.25 ± 13.73 versus 13.85 ± 12.25, respectively; p = 0.002). In both groups, the sperm motility increased significantly at the end of follow-up compared to the preoperative period. The postoperative sperm mortality remained significantly higher in group II than in group I (p = 0.008). CONCLUSIONS Intraoperative Doppler plus hydrodissection (D+IH-MSV) has advantages in preserving more arteries and enhancing the motility of sperms. Based on these findings, we strongly recommend D+IH-MSV when treating infertile men with varicocele.

World J Mens Health 2023; 41:164-197. [PMID: 35791302 PMCID: PMC9826919 DOI: 10.5534/wjmh.220048] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 03/15/2022] [Accepted: 03/20/2022] [Indexed: 02/06/2023] Open
Abstract
PURPOSE Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility. MATERIALS AND METHODS Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field. RESULTS The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available. CONCLUSIONS This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.

Abstract
Varicocele is the most common reversible cause of male infertility, affecting up to 20% of healthy men and 40% of men with primary infertility. The objective of this study was to investigate the prevalence of varicocele in men evaluated for infertility, and to determine rates of subsequent varicocele repair. Since reproductive endocrinologists are the first specialists seen for male infertility care in North America, we hypothesized that varicocele would be underdiagnosed when compared to its reported prevalence among men with infertility. TriNetX, a large, multicenter electronic health record (EHR) database was queried to establish a cohort of all men (above 18 years of age) with a diagnosis of male infertility. This cohort was used to identify those with ensuing varicocele diagnosis. Men who received varicocelectomy or venous embolization after a diagnosis of varicocele were then identified. Out of 101,309 men with a diagnosis of male infertility in the network, only 9768 (9.6%) had a diagnosis of varicocele. Mean age of men with varicocele was 34. Varicocelectomy or venous embolization was performed in 1699 (20.2%) and 69 (0.76%) of men with varicocele, respectively. In this cross-sectional EHR study, varicocele was underdiagnosed in men evaluated for infertility when compared with prior epidemiological studies.

Andrologia 2022; 54:e14512. [PMID: 35753722 DOI: 10.1111/and.14512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 05/26/2022] [Accepted: 06/13/2022] [Indexed: 11/30/2022] Open
Abstract
Varicocele (VCL) is a pathological dilation of the venous pampiniform plexus of the spermatic cord and is also classified as male factor infertility. The current experiment aimed to examine the protective effect of Fumaria parviflora (FP), as a powerful antioxidant, against reproductive damage induced by VCL. In this experimental study, 32 male rats were randomly allocated into four groups, namely sham (simple laparotomy without additional intervention), FP (healthy rats administered 250 mg/kg FP), VCL + FP (underwent VCL and received 250 mg/kg FP), VCL (underwent VCL without receiving any treatment). The results showed that the number of Sertoli and germ cells were markedly reduced in the VCL group in comparison to the FP-treated and sham groups. The VCl + FP group had significantly higher serum levels of testosterone (T), FSH, and LH hormones than the VCL group. The quality and motility of spermatozoa were reduced in the VCL group compared with other groups (p ≤ 0.05). Moreover, our findings demonstrated that the administration of FP considerably enhanced the mRNA levels of CatSper-1 and -2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR (p ≤ 0.05). Based on the obtained results, treatment with FP is capable of preventing testicular dysfunction and elevating the concentration of hormones and some crucial genes, such as CatSper1 and 2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR that contribute to the spermatogenesis process.

The Role of NLRP3 Inflammasome Activation and Oxidative Stress in Varicocele-Mediated Male Hypofertility. Int J Mol Sci 2022; 23:ijms23095233. [PMID: 35563625 PMCID: PMC9102453 DOI: 10.3390/ijms23095233] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 05/03/2022] [Accepted: 05/05/2022] [Indexed: 12/11/2022] Open
Abstract
Varicocele (VC) is the most common abnormality identified in men evaluated for hypofertility. Increased levels of reactive oxygen species (ROS) and reduced antioxidants concentrations are key contributors in varicocele-mediated hypofertility. Moreover, inflammation and alterations in testicular immunity negatively impact male fertility. In particular, NLRP3 inflammasome activation was hypothesized to lead to seminal inflammation, in which the levels of specific cytokines, such as IL-1β and IL-18, are overexpressed. In this review, we described the role played by oxidative stress (OS), inflammation, and NLRP3 inflammasome activation in VC disease. The consequences of ROS overproduction in testis, including inflammation, lipid peroxidation, mitochondrial dysfunction, chromatin damage, and sperm DNA fragmentation, leading to abnormal testicular function and failed spermatogenesis, were highlighted. Finally, we described some therapeutic antioxidant strategies, with recognized beneficial effects in counteracting OS and inflammation in testes, as possible therapeutic drugs against varicocele-mediated hypofertility.

Abstract
Physical and mental health and hormonal imbalance are associated with the problems related to infertility and reproductive disorders. The rate of infertility has increased globally over the years, due to various reasons. Given the psychosocial implications of infertility and its effects on the life of the affected people, there has been an increased focus on its treatment over the last several years. Assisted reproductive technology can only solve about 50% of the cases. Moreover, it contains significant risks and does not solve the fundamental problem of infertility. As pluripotent stem cells have the potential to differentiate into almost any type of cell, they have been widely regarded as a promising option in the development of stem cell-based fertility treatments, which could even correct genetic diseases in offspring. These advancements in reproductive biotechnology present both challenges and possibilities for solving infertility problems caused by various unexplainable factors. This review briefly presents the different types of infertility disorders and the potential applications of stem cells in the treatment of these reproductive diseases.

Abstract
Oxidative stress is a condition due to an imbalance between the concentrations of oxidants and antioxidants, and it is a well-recognized contributor in several male infertility conditions. Varicocele, a common vascular condition, may cause male infertility due to hyperthermia, hypoxia and/or exposure to toxic adrenal and renal metabolites. In this review, the mechanisms by which oxidative stress can affect cellular integrity and functions are described, along with molecular markers of cellular oxidative damage, and the most commonly performed techniques for their detection in seminal fluid. Moreover, we focus on the role of oxidative stress in the pathophysiology of varicocele based on recently published evidence from omics based studies, such as proteomics and genomics. Finally, we discuss strategies for the management of oxidative stress and the clinical guidelines for testing oxidative stress-related sperm DNA fragmentation in this group of patients.

Abstract
Infertility affects 10%-15% of couples worldwide. Of all infertility cases, 20%-70% are due to male factors. In the past, men with severe male factor (SMF) were considered sterile. Nevertheless, the development of intracytoplasmic sperm injection (ICSI) drastically modified this scenario. The advances in assisted reproductive technology (ART), specifically regarding surgical sperm retrieval procedures, allowed the efficacious treatment of these conditions. Yet, before undergoing ICSI, male factor infertility requires careful evaluation of clinical and lifestyle behavior together with medical treatment. Epidemiologically speaking, women whose male partner is azoospermic tend to be younger and with a better ovarian reserve. These couples, in fact, are proposed ART earlier in their life, and for this reason, their ovarian response after stimulation is generally good. Furthermore, in younger couples, azoospermia can be partially compensated by the efficient ovarian response, resulting in an acceptable fertility rate following in vitro fertilization (IVF) techniques. Conversely, when azoospermia is associated with a reduced ovarian reserve and/or advanced maternal age, the treatment becomes more challenging, with a consequent reduction in IVF outcomes. Nonetheless, azoospermia seems to impair neither the euploidy rate at the blastocyst stage nor the implantation of euploid blastocysts. Based on the current knowledge, the assessment of male infertility factors should involve: (1) evaluation - to diagnose and quantify seminologic alterations; (2) potentiality - to determine the real possibilities to improve sperm parameters and/or retrieve spermatozoa; (3) time - to consider the available "treatment window", based on maternal age and ovarian reserve. This review represents an update of the definition, prevalence, causes, and treatment of SMF in a modern ART clinic.

Abstract
Our study aimed to assess for predictors of varicocele-associated pain and whether it predicts semen parameters after microsurgical varicocelectomy. We assessed all men diagnosed with a varicocele by two surgeons from 2017 to 2020, excluding those who did not undergo surgical treatment. Patients were stratified based on the presence of pain at clinical assessment, and these groups were compared. Logistic regression models were utilised to assess for predictors of pain. A total of 313 men were included, with relatively similar proportions completed by both surgeons (48.2% and 51.8%). A total of 98 (31.3%) had typical varicocele-associated pain at the time of assessment. The pain group was younger than the no pain group (30.5 versus. 35.0, respectively, p < .01), and those with pain had greater varicocele grades (p = .008). Although not statistically different, there was a greater portion of left-sided only varicoceles in the pain group (p = .09). No significant differences were demonstrated between sperm concentration, motility, volume or morphology pre-operatively, or post-operatively between groups. Younger age and varicocele grade were predictive of varicocele-associated pain. In conclusion, almost 1/3 of men presented with varicocele-associated pain. Pain does not predict response to varicocelectomy, but these men tend to be younger, and have higher grade varicoceles.

Abstract
PURPOSE Several diseases have been identified as stressful factors for herpes zoster (HZ) infection. In this study, we investigated the risk of HZ infection in men with varicocele. METHODS We enlisted the data of patients with newly diagnosed varicocele between 2000 and 2012 from the Taiwanese National Health Insurance Research Database as case cohort. Four control patients were matched as per age and index year to a case patient. HZ diagnosis was the primary end point, and the follow-up period was considered as the time interval from the index date to the main outcome, withdrawal from the National Health Insurance program, or end of the study (31 December 2013). RESULTS In total, 8720 patients were recruited (1744 with varicocele and 6976 controls); the overall mean age was 36 years. Majority (85%) of the participants were 20-49 years old. HZ incidence was higher in patients with varicocele (5.60 per 1,000 person-years) than in the control group (4.01 per 1,000 person years). Patients with varicocele were 1.37 times more likely to develop HZ than the controls after adjustment. Compared with the control cohort, the adjusted hazards ratio (HR) of the varicocele cohort was higher in patients younger than 49 years old (adjusted HR = 1.60). CONCLUSION Men with varicocele had a higher risk of HZ development than those without varicocele, particularly those aged ≤49 years. Thus, stress from varicocele cannot be ignored in young men.

Abstract
BACKGROUND Little is known about the role of the genitourinary and gastrointestinal microbiota in the pathogenesis of male infertility. OBJECTIVE To compare the taxonomic and functional profiles of the gut, semen, and urine microbiomes of infertile and fertile men. DESIGN, SETTING, AND PARTICIPANTS We prospectively enrolled 25 men with primary idiopathic infertility and 12 healthy men with proven paternity, and we collected rectal swabs, semen samples, midstream urine specimens, and experimental controls. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We performed comprehensive semen analysis, 16S rRNA sequencing for quantitative high-resolution taxonomy, and shotgun metagenomics with a median of 140 million reads per sample for functional metabolic pathway profiling. RESULTS AND LIMITATIONS We identified a diverse semen microbiome with modest similarity to the urinary microbiome. Infertile men harbored increased seminal α-diversity and distinct β-diversity, increased seminal Aerococcus, and decreased rectal Anaerococcus. Prevotella abundance was inversely associated with sperm concentration, and Pseudomonas was directly associated with total motile sperm count. Vasectomy appeared to alter the seminal microbiome, suggesting a testicular or epididymal contribution. Anaerobes were highly over-represented in the semen of infertile men with a varicocele, but oxidative stress and leukocytospermia were associated with only subtle differences. Metagenomics data identified significant alterations in the S-adenosyl-L-methionine cycle, which may play a multifaceted role in the pathogenesis of infertility via DNA methylation, oxidative stress, and/or polyamine synthesis. CONCLUSIONS This pilot study represents the first comprehensive investigation into the microbiome in male infertility. These findings provide the foundation for future investigations to explore causality and identify novel microbiome-based diagnostics and therapeutics for men with this complex and emotionally devastating disease. PATIENT SUMMARY We explored the resident populations of bacteria living in the gut, semen, and urine of infertile and fertile men. We found several important bacterial and metabolic pathway differences with the potential to aid in diagnosing and treating male infertility in the future.

Abstract
Nonobstructive azoospermia, (NOA) is the most common cause of azoospermia. NOA is characterized by hypergonadotropic hypogonadism, testicular failure, and impaired spermatogenesis. The recent development of surgical sperm retrieval techniques such as microsurgical testicular sperm extraction (mTESE) has, for the first time, allowed some men with NOA to father biological children. It is common practice for endocrine stimulation therapies such as gonadotropins, selective estrogen receptor modulators (SERMs), and aromatase inhibitors to be used prior to mTESE to increase intratesticular testosterone synthesis with the aim of improving sperm retrieval rates; however, there is currently a paucity of data underpinning their safety and efficacy. We present 2 cases of men with NOA undergoing endocrine stimulation therapy and mTESE. We also discuss the current evidence and controversies associated with the use of hormonal stimulation therapy in couples affected by this severe form of male infertility.

Abstract
Assisted reproductive technologies (ART) are considered as one of the primary management options to address severe male factor infertility. The purpose of this study was to identify the research trends in the field of male infertility and ART over the past 20 years (2000-2019) by analysing scientometric data (the number of publications per year, authors, author affiliations, journals, countries, type of documents, subject area and number of citations) retrieved using the Scopus database. We used VOS viewer software to generate a network map on international collaborations as well as a heat map of the top scientists in this field. Our results revealed a total of 2,148 publications during this period with Cleveland Clinic Foundation contributing the most (n = 69). The current scientometric analysis showed that the research trend on ART has been stable over the past two decades. Further in-depth analysis revealed that density gradient centrifugation (46%) and intracytoplasmic sperm injection (59.2%) are the most reported techniques for sperm separation and ART, respectively. Additionally, azoospermia was the most studied clinical scenario (60.6%), with majority of articles reporting pregnancy rate (47.25%) as the primary reproductive outcome for ART. This study provides insight into the current focus of research in the area of male infertility and ART as well as the areas that require further research in future.

Abstract
Clinically, infertility is defined as the inability to conceive after a certain period. In contrast, sterility is defined as the inability to produce a biological child; however, this is not a practical definition that can be applied in a clinical setting to a patient’s diagnosis. Unlike infertility, sterility is rarely discussed in biomedical and clinical literature and is often used synonymously with infertility. Infertility affects about 10% of couples globally, but the prevalence of sterility remains unknown. We divide sterility into three subtypes natural, clinical, and hardship. To estimate sterility prevalence, we analyzed primary literature and meta-analysis papers on the rates of live births and pregnancies throughout several treatments of infertile couples (e.g., untreated patients, in vitro fertilization-treated, and patients administered other treatments). This analysis indicates that all treatments fail in delivering a biological child to most couples, suggesting that most infertile couples may fail to conceive. More comprehensive primary studies are needed to provide a precise estimate of sterility. Furthermore, research is needed to study the causes of sterility, as well as develop methods for diagnosis and treatment that are financially affordable and emotionally tolerable. Altogether, sterility is an under-discussed condition that is more common than expected, as many infertile couples are unable to conceive and are, in effect, sterile.

Abstract
Varicocele is one of the leading causes of male infertility in which oxidative stress induces DNA damages in spermatozoa of patients with varicocele. Recent studies indicated that the treatment with antioxidant agents has protective effects against the formation of reactive oxygen species (ROS). Our research aimed to evaluate the impact of Fumaria Parviflora (FP) on the varicocele-induced testicular injury. For this purpose, 32 adult male Wistar rats (n = 8 per group) were randomly assigned to four groups as follows: sham group, varicocele group, varicocele treatment group and the control treatment group. The experimental groups daily received FP (250 mg/kg) for 8 weeks. The induction of varicocele was conducted by partial occlusion on the left renal vein. The diameter of seminiferous tubules, Johnsen's score and the epithelium thickness improved in the treated-varicocele group as compared to the varicocele group. FP extract could increase the biochemical parameters including superoxide dismutase and glutathione peroxidase, and also decrease malondialdehyde level in the varicocele group. Furthermore, varicocele markedly increased both mRNA and intensity of Bax, while treatment with FP could alleviate them. We concluded that FP could alleviate varicocele, possibly by lowering oxidative stress and testicular damage.

Abstract
Since autophagy was suspected to occur in the pathological situation of varicocele (VCL), we have attempted to confirm it here using a surgical model of varicocele-induced rats. Thirty Wistar rats were divided into three groups (varicocele/sham/control) and analyzed two months after the induction of varicocele. Testicular tissue sections and epididymal mature sperm were then monitored for classic features of varicocele, including disturbance of spermatogenesis, impaired testicular carbohydrate and lipid homeostasis, decreased sperm count, increased sperm nuclear immaturity and DNA damage, oxidative stress, and lipid peroxidation. At the same time, we evaluated the Atg7 protein content and LC3-II/LC3-1 protein ratio in testis and mature sperm cells, two typical markers of early and late cellular autophagy, respectively. We report here that testis and mature sperm show higher signs of autophagy in the varicocele group than in the control and sham groups, probably to try to mitigate the consequences of VCL on the testis and germ cells.

Abstract
Varicocele is the most common correctable cause for male infertility, but not all men with varicocele are affected equally by this condition. The pathophysiology of varicocele-induced fertility remains ill-defined. While evidence suggests that oxidative stress remains a central factor, other mechanisms likely include scrotal hyperthermia, reflux of metabolites, hypoxia and cadmium accumulation. Microsurgical varicocelectomy remains the gold standard treatment option for infertile men with a clinically palpable varicocele and abnormal semen parameters. Newer evidence suggests a potential role for antioxidant supplementation and a meaningful role of varicocelectomy for patients destined for ART to improve pregnancy outcomes.

Abstract
Significance: Male reproductive research at molecular level has gained more attention as it offers the cellular mechanisms and biological pathways implicated in the reproductive physiology. Several researchers across the world have used global proteomic approach in conjunction with advanced bioinformatics software to identify putative biomarkers for various male infertility conditions. Recent Advances: Introduction of advance proteomic platforms has made it easier to generate enormous amount of data in a short period of time. In this article, we have reviewed the functional and comparative proteomic studies in the area of male reproductive research. We have discussed the key proteins and associated cellular pathways such as oxidative phosphorylation and mitochondrial dysfunction implicated in the various male infertility conditions. Furthermore, for the first time scientometric approach was used to analyze the publication trends and hot topics in proteomics of male reproductive research. Critical Issues: Analysis of publication trends revealed that majority of the published studies were focused on varicocele and asthenozoospermia, while very limited research has been conducted on assisted reproductive technology (ART). This area of research requires more attention as it would facilitate identification of novel biomarkers to catalogue proteomic characteristics of spermatozoa for achieving better results in ART. Future Directions: Future research should be focused on the development and validation of a biomarker panel for specific male infertility scenarios based on etiology. Translation of validated proteomic biomarkers into tests or assays for male infertility conditions would enable the physician to provide better management for the patients.

Abstract
Purpose This study evaluated the relationships of varicocele characteristics and surgical methods with the pain resolution rate post-varicocelectomy. Materials and Methods A literature search was conducted using PubMed (MEDLINE) and Embase (1980 to December 2018). The keywords used for the search were “varicocele,” “varicocelectomy OR ligation OR repair,” and “pain OR painful.” Two authors independently reviewed the titles and abstracts of the retrieved articles. Studies were evaluated for eligibility, and those that fulfilled all of the inclusion criteria and none of the exclusion criteria were selected for full-text review. Results Fourteen studies were included in the analysis. There were no significant differences in the postoperative pain resolution rate with respect to varicocele grades I, II, and III. The resolution rate was significantly higher for dull pain than for dragging and sharp pain (odds ratio [OR], 5.73; 95% confidence interval [CI], 1.78–18.41; p=0.003 and OR, 8.72; 95% CI, 2.91–26.08; p=0.0001, respectively). In terms of the surgical approach, subinguinal ligation was significantly more effective in terms of pain resolution than high ligation (OR, 2.73; 95% CI, 1.54–4.85; p=0.0006). Microsurgical varicocelectomy showed a significantly higher likelihood of pain resolution than laparoscopic varicocelectomy (OR, 7.12; 95% CI, 3.78–13.44; p<0.0001). Conclusions Patients with varicocele complaining of dull pain preoperatively had a higher likelihood of postoperative pain resolution than those complaining of dragging or sharp pain. Furthermore, subinguinal ligation was more effective for pain resolution than high ligation, and microsurgical varicocelectomy showed better surgical outcomes than laparoscopic varicocelectomy.

Abstract
To investigate whether bilateral surgery can bring more benefits to infertile patients with bilateral varicocele than unilateral surgery. A search of PubMed, Web of Science, EMBASE and the Cochrane Library on 13 January 2019 was conducted to identify studies published in English that used varicocelectomy. The protocol of the present meta-analysis was pre-published on PROSPERO (registration number CRD42019093894). Primary outcomes were spontaneous pregnancy rates. A total of eleven articles were finally enrolled in, with a total of 1,743 patients. Spontaneous pregnancy rate was higher in patient with bilateral varicocelectomy than unilateral varicocelectomy with an odds ratio (OR) of 1.89 (95% CI 1.52-2.35; I2 = 0%; p < .00001). The results indicated bilateral is superior than unilateral varicocelectomy concerning sperm concentration (SMD: 2.88 × 106 /ml; 95% CI: 1.06, 4.70; I2 = 93%), sperm motility (SMD: 5.08; 95% CI: 2.65, 7.50; I2 = 0%), progression of sperm motility (SMD: 6.48; 95% CI: 5.16, 7.81; I2 = 0%) and sperm morphology (SMD: 2.38%; 95% CI: 0.72, 4.03; I2 = 94%) between bilateral and unilateral varicocelectomy. Bilateral varicocelectomy may be superior to unilateral in regard to spontaneous pregnancy rate and sperm motility for infertile male with bilateral varicocele (both left clinical and right subclinical varicocele and bilateral clinical varicocele).

Abstract
We investigated the clinical characteristics of patients with varicocele according to the presence or absence of scrotal pain. We retrospectively reviewed the records of patients who underwent varicocelectomy. The age, body mass index, grade, laterality of varicocele, testicular volume difference, time to hospital visit, serum testosterone level and semen parameters were evaluated. A total of 954 patients were included. The painful group had lower mean age, lower BMI, higher grade of varicocele, smaller testicular volume difference and shorter time to hospital visit than the painless group. In addition, the median serum total testosterone level and total sperm count, concentration and motility were higher in the painful group than in the painless group. In multivariate analysis, there were significant differences between the two groups in age, grade of varicocele, testis volume difference, time to hospital visit, total sperm count and concentration. Patients with painful varicocele visited hospital earlier because of the pain and tended to start treatment sooner. They were also younger, had smaller testis atrophy and had higher sperm concentration, even though they had a higher grade of varicocele than patients without pain. Although scrotal pain in varicocele patients is difficult to treat, it leads to early diagnosis and treatment.
