Abstract
INTRODUCTION Previous work has demonstrated a deficiency in urology resident education when it comes to andrology and male infertility. We analyzed the top 100 most frequently cited and influential articles published on testosterone deficiency and its associated therapy, allowing trainees and clinicians to review and understand the characteristics of impactful literature for self-directed learning purposes. METHODS The ISI Web of Knowledge database was used to find articles on testosterone deficiency, hypogonadism, and replacement therapies. Relevant, peer-reviewed, English articles were included. Article details, including title, citation count, publication year, and more, were gathered. Articles were classified based on content (e.g. clinical outcomes, anatomy, and trends) using defined criteria. RESULTS The top 300 most cited were reviewed with 100 included. The most cited article had 774 citations, averaging 234 in the top 100. Publication years had peaks in 2003-2004 and 2006-2007. The US led in publications (56), followed by England (16), Germany (14), and Italy (13). Common affiliations included US Department of Veteran Affairs, Veterans Health Administration, RIC Research Education Clinical Center, and University of California System. Articles were categorized as LOE 2 (47), LOE 1 (22), and LOE 5 (21). Articles focused on clinical outcomes (71.7%), anatomy/biomechanics/physiology (14.1%), clinical guidelines (8.1%), and screening (4%). The "Journal of Clinical Endocrinology & Metabolism" published 26 of the top 100 cited articles. CONCLUSIONS This analysis highlights influential articles regarding testosterone deficiency and management. The discussed articles have significant clinical and therapeutic implications for the practicing urologist which may bolster deficits in current resident education.

Abstract
CatSper affects sperm function and male fertilization capacity markers, including sperm motility and egg penetration. The study has aimed to evaluate the mRNA expression of CatSper1, and CatSper3 in the spermatozoa of men with normozoospermia and Asthenoteratozoospermia, and to assess the correlation between genes expression and sperm parameters, fertilization rate, and embryo quality in intracytoplasmic sperm injection (ICSI). Reverse transcription-polymerase chain reaction was utilized to evaluate the mRNA expression of CatSper1 and CatSper3 in sperm in two patient groups: Normozoospermia (NOR; n = 32), and Asthenoteratozoospermia (AT; n = 22). In all patients receiving intracytoplasmic sperm injection, the fertilization rate and embryo quality were evaluated. CatSper1, and CatSper3 mRNA expression in sperm was significantly lower in AT males than in NOR (P < 0.05). Levels of these genes demonstrated a significant positive correlation with sperm motility, mitochondrial membrane potential (MMP), capacitation, fertilization rate, cleavage rate, and embryo quality (P < 0.05) following ICSI. However, a negative correlation was found between mRNA expression of CatSper1, 3 and sperm DNA fragmentation (P < 0.05). Findings indicate low levels of CatSper1 and CatSper3 mRNA expression in men with Asthenoteratozoospermia, which resulted in poor sperm quality and impaired embryo development following ICSI therapy.

Abstract
Microplastics (MPs) are global environmental pollutants with potential toxicity concerns, and their effects on the reproductive system have attracted increasing attention. This study investigated the interaction between MPs and mammalian biomolecules, focusing on the relationship between the testosterone adsorption behavior of MPs and male reproductive health. The adsorption capacity of different types of MPs for testosterone was evaluated in vitro experiments. Polyamide (PA)-MPs exhibited stronger adsorption, while polymethyl methacrylate (PMMA)-MPs displayed the weakest adsorption. Sorption equilibrium between PA-MPs and testosterone was achieved within 6 h, fitting the Pseudo-2nd-order model and Langmuir isotherm. The effects of MPs on male reproduction in mice was determined in vivo experiments. Male mice were treated with 0.1 and 0.5 mg/d PA-MPs/PMMA-MPs by gavage once per day for 28 days. The results showed that only 0.5 mg/d PA-MP exposure induced decreased serum testosterone levels, increased testicular testosterone levels compared to the control, and more severe damage to seminiferous tubule structure, sperm motility and sperm morphology compared to the PMMA-MPs group. Meanwhile, PA-MPs could reduce intracellular nuclear translocation of androgen receptor (AR) mediated by testosterone, while PMMA-MPs had no impact. The study revealed that PA-MP adsorption reduced testosterone bioavailability and caused sperm quality to decline, offering new insights into the combined toxicity mechanism of MPs in male mammals.

Abstract
Recent achievements in reproductive biomedicine have led to a revolution in infertility treatment. A comprehensive understanding of the current status of reproductive medicine is necessary for the development of a forward-looking plan by health policymakers, based on fundamental requirements. This study is a systematic review of the Scopus database to assess reproductive biomedicine publications within Iran and compared to the rest of the world from 1990 to 2020. The data were categorized by geographical distribution across five continents. National data were assessed in comparison with the world and with neighboring countries. Finally, prominent national research institutes in the field of reproductive biomedicine in Iran were identified, and their contributions to the field highlighted. Of the five continents, the highest number of publications and citations is from Europe (36% publications and 41.5% citations). Corresponding numbers for the other continents are 32 and 33% for America, and 26 and 18.4% for Asia respectively. The remaining publications and citations were from Australia (3.8 and 4.1%) and Africa (2.6 and 3.1%). In a national analysis, the highest-ranking institutes in reproductive biomedicine are in Tehran province (50.9% of all Iranian publications), Shiraz (8.8%), Yazd (7.8%), Isfahan (7.1%), and Tabriz (6.9%). More specifically, Tehran University of Medical Science (15.9%), the Royan Institute (12.2%), Shahid Beheshti Medical University (10.1%), Shahid Sadoughi University of Medical Sciences (6.9%), and Tarbiat Modares University (6.7%) account for more than 50% of all Iranian scientific publications. In recent decades, reproductive biomedical research has grown significantly in Iran. Reviewing publications in this field helps health policy decision makers to monitor the direction of research and adjust investment in the treatment of infertility. In addition, it is necessary to expand and organize inter-organizational and international collaborations to improve the research, gain the benefits of different experiences, and engage in international multicenter studies.

Front Endocrinol (Lausanne) 2023; 14:1266730. [PMID: 38027184 PMCID: PMC10650597 DOI: 10.3389/fendo.2023.1266730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 10/09/2023] [Indexed: 12/01/2023] Open
Abstract
Background Klinefelter's syndrome (KS) was once considered infertile due to congenital chromosomal abnormalities, but the presence of focal spermatozoa changed this. The key to predict and promote spermatogenesis is to find targets that regulate focal spermatogenesis. Objective To explore the trend of fertility changes in KS patients at different ages and identify potential therapeutic targets. Methods Bibliometric analysis was used to collect clinical research data on KS from the Web of Science Core Collection (WoSCC) from 1992 to 2022. A cross-sectional study was conducted on 75 KS patients who underwent microscopic testicular sperm extraction (mTESE) from 2017 to 2022 in the real world. The reproductive hormones, testicular histopathology, androgen receptors, insulin-like factor 3 (INSL3) receptors and sperm recovery rate (SRR) were analyzed. Results Male infertility, dysplasia, Sertoli cells, Leydig cells, testosterone and spermatogenesis were the research focuses related to KS. Luteinizing hormone (LH), testosterone, and INSL3 were evaluation indicators of Leydig cell function that fluctuate with age. Testosterone and LH peaked at ages 13-19 and 30-45, while INSL3 only peaked at ages 13-19. 27 patients (27/75) recovered sperm through mTESE and experienced SRR peaks at the ages of 20, 28, 34, and 37. The SRR of fibrosis patients was 46.15%, fatty degeneration was 7.14%, and melanosis was 40.00%. The INSL3 and androgen receptors were highly expressed and roughly balanced in focal spermatogenesis. Conclusion Abnormal metabolism of Leydig cells led to imbalanced expression of INSL3 and androgen receptors, which might be a potential target for spermatogenesis in KS.

[PMID: 37987419 PMCID: PMC10660474 DOI: 10.3390/clinpract13060118] [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: 09/13/2023] [Revised: 10/13/2023] [Accepted: 10/20/2023] [Indexed: 11/22/2023] Open
Abstract
The COVID-19 pandemic due to the SARS-CoV-2 coronavirus showed acute and prolonged effects on human health. In addition, over the past four years, there has been a tremendous surge in COVID-19-related scientific publications, as shown by bibliometric and scientometric studies. However, such analysis of the scientific literature is lacking in the area of male reproduction. The current scientometric study analyzes publication characteristics of articles related to male reproduction and COVID-19 infection. We used the Scopus database to analyze scientometric data (the number of publications, journals, countries, type of documents, and subject area) related to COVID-19 and male reproductive research. Our literature search identified 345 articles related to COVID-19 and male reproductive research. Most of the articles were published in the USA (n = 72), Italy (n = 55), and China (n = 51). Such research was mainly focused around medicine (57.1%), followed by biochemistry, genetics, and molecular biology (25.7%). Also, in the area of male reproduction, only 37.1% (n = 128) of the articles contributed towards original research, whereas 52.8% (n = 182) were review articles and editorials focusing more on sexual dysfunction than infertility. Such a small number of studies published on COVID-19-related effects on male reproduction warrants a significant increase in research, which is required to decipher the mechanism(s) underlying SARS-CoV-2 infection-associated impairment of male reproductive function.

Toxicol In Vitro 2023; 92:105658. [PMID: 37544489 DOI: 10.1016/j.tiv.2023.105658] [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: 04/10/2023] [Revised: 07/16/2023] [Accepted: 07/30/2023] [Indexed: 08/08/2023]
Abstract
Aluminum chloride (AlCl3) exposure is pervasive in our daily lives. Numerous studies have demonstrated that exposure to AlCl3 can lead to male reproductive toxicity. However, the precise mechanism of action remains unclear. The objective of this study is to investigate the mechanism of aluminum-induced toxicity by analyzing the alterations in the global transcriptome gene profile of mouse spermatocytes (GC-2spd cells) exposed to AlCl3. GC-2spd cells were exposed to concentrations of 0, 1, 2, and 4 mM AlCl3, and high-throughput mRNA-seq was performed to investigate the changes in the transcriptome after exposure to 4 mM AlCl3. Our findings indicate that exposure to AlCl3 led to an increase in oxidative stress, disrupted glutathione metabolism, reduced cell viability, and altered gene expression in mouse spermatocytes. Gene enrichment analysis revealed that the differentially expressed genes (DEGs) were associated with various biological functions such as mitochondrial inner membrane, response to oxidative stress. Furthermore, these DEGs were found to be enriched in pathways including proteasome, glutathione metabolism, oxidative phosphorylation, and Hif-1 signaling pathway. Real-time PCR and western blot were employed to validate the expression alterations of pivotal genes, and the outcomes exhibited concordance with the mRNA-seq findings. This study provides a theoretical basis for revealing the potential mechanism of male reproductive toxicity caused by aluminum exposure.

Abstract
Background Penile cancer is a malignant tumor of the genitourinary system that mostly occurs in middle-aged and elderly men aged 50-70 years, which can seriously affect physical, psychological, and sexual health. Hundreds of original articles and reviews on penile cancer are published each year. However, a bibliometric analysis of these publications has not been performed. Objective This study aimed to systematically analyze and visualize penile cancer-related publications through bibliometrics and reveal identified topics, hotspots, and knowledge gaps in related fields. Methods Based on the Web of Science core collection database, we first analyzed the quantity and quality of publications in the field of penile cancer. Second, we profiled the publishing groups in terms of country, institution, author's publication, and cooperation network. Then, we systematized and summarized the hot topics of research. Results This bibliometric analysis was conducted from 2001 to 2022. The analysis identified 1,687 articles and reviews, which were published in 432 journals. The number of publications and citations on penile cancer-related research has steadily increased over the last two decades. Furthermore, academic institutions in Europe and the United States play a leading role in penile cancer research. The country, institution, journal, and author with the most publications were the United States (507), H Lee Moffitt Cancer Research Center (96), Journal of Urology (83), and Spiess P (87), respectively. The most frequently used keywords were penile cancer (743), squamous-cell carcinoma (717), cancer (380), carcinoma (232), lymphadenectomy (229). 16 keyword clustering information was obtained, including #0 male circumcision, #1 lichen sclerosus, #2 chemotherapy, #3 penile neoplasms, #4 targeted therapy, #5 resection margin, #6 cervical cancer, #7 lymph node dissection, #8 prognostic factor, #9 prostate cancer, #10 inguinal lymph node dissection, #11 human papillomavirus DNA, #12 gene, #13 penile intraepithelial neoplasia, #14 male sexual function, and #15 penile cancer. Conclusion More and more scholars are devoted to the research on penile cancer. This bibliometric analysis revealed that the main research topics and hotspots in penile cancer included risk factors and surgical treatment plans.

Yang Y, Tan X, Shi Y, Deng J. What are the core concerns of policy analysis? A multidisciplinary investigation based on in-depth bibliometric analysis. HUMANITIES & SOCIAL SCIENCES COMMUNICATIONS 2023; 10:190. [PMID: 37152400 PMCID: PMC10150689 DOI: 10.1057/s41599-023-01703-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 04/18/2023] [Indexed: 05/09/2023]
Abstract
Policy analysis provides multiple methods and tools for generating and transforming policy-relevant information and supporting policy evolution to address emerging social problems. In this study, a bibliometric analysis of a large number of studies on historical policy analysis was performed to provide a comprehensive understanding of the distribution and evolution of policy problems in different fields among countries. The analysis indicates that policy analysis has been a great concern for scholars in recent two decades, and is involved in multiple disciplines, among which the dominant ones are medicine, environment, energy and economy. The major concerns of policy analysts and scholars are human health needs, environmental pressures, energy consumption caused by economic growth and urbanization, and the resulting demand for sustainable development. The multidisciplinary dialog implies the complicated real-world social problems that calls for more endeavors to develop a harmonious society. A global profiling for policy analysis demonstrates that the central policy problems and the corresponding options align with national development, for example, developing countries represented by China are faced with greater environmental pressures after experiencing extensive economic growth, while developed countries such as the USA and the UK pay more attention to the social issues of health and economic transformation. Exploring the differences in policy priorities among countries can provide a new inspiration for further dialog and cooperation on the development of the international community in the future.

Consensus and Diversity in the Management of Varicocele for Male Infertility: Results of a Global Practice Survey and Comparison with Guidelines and Recommendations. 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.

[PMID: 36177695 DOI: 10.1002/prca.202200060] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/12/2022] [Accepted: 09/21/2022] [Indexed: 01/28/2023]
Abstract
PURPOSE Azoospermia, as the most severe form of male infertility, no longer indicates sterility due to modern medical advancements. The current diagnostic procedure based on testicular biopsy has several drawbacks which urges the development of novel, non-invasive diagnostic procedures based on biomarkers. In the last two decades, there have been many proteomics studies investigating potential azoospermia biomarkers. In this review, we aimed to provide a critical evaluation of these studies. EXPERIMENTAL DESIGN Published articles were gathered by systematic literature search using Pubmed, Science Direct, and Google Scholar databases until March 2022 and were further preselected to include only studies on human samples. RESULTS A detailed review of these studies encompassed the proteomics platforms, sources of material, proposed candidate biomarkers, and their potential diagnostic specificity and sensitivity. In addition, emphasis was put on the top, most identified and validated biomarker candidates and their potential for discriminating azoospermia types and subtypes as well as predicting sperm retrieval success rate. CONCLUSIONS Proteomics research of azoospermia has laid the groundwork for the development of a more streamlined biomarker testing. The future research should be focused on well-designed studies including samples from all types/subtypes as well as further testing of the most promising biomarkers identified so far.

Are There Associations between Seminal Plasma Advanced Oxidation Protein Products and Selected Redox-Associated Biochemical Parameters in Infertile Male Patients? A Preliminary Report. Cells 2022; 11:cells11223667. [PMID: 36429095 PMCID: PMC9688436 DOI: 10.3390/cells11223667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 11/05/2022] [Accepted: 11/16/2022] [Indexed: 11/22/2022] Open
Abstract
Oxidative stress (OS) is one of the reasons for male infertility. Seminal plasma contains a multitude of enzymes and ions which influence OS and thus may affect male fertility. The aim of the study was to check for associations between seminal plasma advanced oxidation protein products (AOPP) concentrations and levels of selected biochemical parameters (total protein, iron, uric acid, magnesium, calcium) in infertile men, and establish whether they are associated with sperm disorders. Seminal plasma AOPP, as well as total protein, iron, uric acid, calcium, and magnesium concentrations, were determined for the following patient groups: normozoospermic (N; n = 33), teratozoospermic (T; n = 30), asthenoteratozoospermic (AT; n = 18), and oligoasthenoteratozoospermic (OAT; n = 28). AOPP concentrations were significantly higher in N and T groups in comparison to AT and OAT groups. Total protein concentrations were significantly lower in the T group in comparison to the AT and OAT groups, whereas iron concentrations significantly decreased in the OAT group in comparison to the T and N patients. AOPP differentiates AT patients from men with other sperm disorders. Our results suggest that asthenozoospermia may be connected with total protein levels. Insufficient iron levels may reflect a decrease in sperm count.

Abstract
BACKGROUND Bladder cancer is one of the most common urological cancers. Non-muscle invasive bladder cancer (NMIBC) accounts for about 75-85% of all newly diagnosed bladder cancers. Globally, there are many NMIBC-related publications. However, a bibliometric analysis of these publications has not been performed. OBJECTIVE This study aims to systematically analyze and visualize NMIBC-related publications through bibliometrics, and to reveal identified topics, hotspots, and knowledge gaps in related fields. METHODS Based on the Web of Science core collection database, we firstly analyzed the quantity and quality of publications in the field of NMIBC, secondly profiled the publishing groups in terms of country, institution, author's publication and cooperation network, and finally sorted out and summarized the hot topics of research. RESULTS This bibliometric analysis was conducted from 2001 to 2022. The analysis identified 2,185 articles and reviews, which were published in 402 journals. The number of publications and citations on NMIBC-related research has steadily increased over the last two decades. Furthermore, academic institutions in Europe and the United States play a leading role in NMIBC research. The country, institution, journal, and author with the most publications were the United States (559), Radboud University Nijmegen (88), Urologic oncology: Seminars and Original Investigations (141), and Witjes J (74), respectively. The most frequently used keywords were Bladder cancer (793), Recurrence (671), Urothelial carcinoma (593), Progression (523), Bacillus-calmette-guerin (411), Transitional-cell carcinoma (401), Carcinoma (366), Risk (297), Transurethral resection (286), and Non-muscle-invasive bladder cancer (280). CONCLUSION More and more scholars are devoted to the research of related NMIBC. This bibliometric analysis revealed that the main research topics and hotspots in NMIBC included pathological staging, clinical diagnosis and treatment, and bladder perfusion.

INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2022; 66:1829-1839. [PMID: 35779167 DOI: 10.1007/s00484-022-02323-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 06/20/2022] [Accepted: 06/28/2022] [Indexed: 06/15/2023]
Abstract
We evaluated the quantity and quality of scientific publications linked with water treatments using the Web of Science (WoS) database. The WoS was searching by using the following terms "hydrotherapy," "balneotherapy," "spa therapy," "spa treatment," "creno-balneotherapy," "water treatments," and "aqua therapy," on February 10th, 2022. The recorded data were the total number of articles, year of articles, country of articles, journal, document type, index data, and citation data. Also, the studies performed with natural source mineral water were marked to make a further subgroup analysis through quality and quantity. We obtained 816 articles; 667 (81.74%) were original research articles, and 149 (18.26%) were review articles. A statistically significant and increasing trend was shown in the publication about water treatments (p < 0.01). About three-quarters of the trials were sourced from high-income countries. Italy (n = 98; 12.01%); Turkey (n = 75; 9.19%); Australia (n = 65; 7.97%); Brazil (n = 46; 5.64%); and France (n = 38; 4.66%) were the most productive countries. Calculating the number of articles per million population, Hungary (3.38), Australia (2.53), and Italy (1.64) ranked in the top three. According to 100 billion dollars GDP, the top three countries were Brazil (24.41), Hungary (21.15), and Turkey (10.41). In the average citation calculation, the Netherlands (60.84), Israel (29.86), and Australia (29.06) were in the top three. The International Journal of Biometeorology was the leading journal for publication trials about water treatments. In the subgroup analysis, we found the total number of studies performed with natural source mineral water and non-specified source water trials as 430 and 386, respectively. We also presented that the natural source and non-specified water trials had a statistically significant and increasing trend between 2000 and 2021 (p < 0.01 and p < 0.01, respectively). The trials performed with natural source water mainly were sourced from Italy (n = 79; 18.37%), Turkey (n = 61; 14.19%), France (n = 38; 8.84%), Poland (n = 30; 6.98%), and Hungary (n = 29; 6.74%), the trials performed with non-specified water were sourced from Australia (n = 61; 15.80%), Brazil (n = 46; 11.92%), USA (n = 27; 6.99%), Italy (n = 19; 4.92%), and England (n = 18; 4.66%). The top journal of the natural source water trials was the International Journal of Biometeorology (n = 65; 15.12%), and for the non-specified water trials, it was the International Journal of Sports Physiology (n = 12; 3.11%).Our study presented an increasing trend in trial publications regarding water treatments between 2000 and 2021. Most of the trials were from high and upper-middle-income countries. We suggest that by demonstrating global productivity worldwide, our results can create more scientific attention on this topic and may promote the quantity and quality of the trials.

Comparative proteomics analysis of human FFPE testicular tissues reveals new candidate biomarkers for distinction among azoospermia types and subtypes. J Proteomics 2022; 267:104686. [PMID: 35914715 DOI: 10.1016/j.jprot.2022.104686] [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: 04/01/2022] [Revised: 07/05/2022] [Accepted: 07/11/2022] [Indexed: 10/16/2022]
Abstract
Understanding molecular mechanisms that underpin azoospermia and discovery of biomarkers that could enable reliable, non-invasive diagnosis is highly needed. Using label-free data-independent LC-MS/MS acquisition coupled with ion mobility, we compared the FFPE testicular proteome of patients with obstructive (OA) and non-obstructive azoospermia (NOA) subtypes hypospermatogenesis (Hyp) and Sertoli cell-only syndrome (SCO). Out of 2044 proteins identified based on ≥2 peptides, 61 proteins had the power to quantitatively discriminate OA from NOA and 30 to quantitatively discriminate SCO from Hyp and OA. Among these, H1-6, RANBP1 and TKTL2 showed superior potential for quantitative discrimination among OA, Hyp and SCO. Integrin signaling pathway, adherens junction, planar cell polarity/convergent extension pathway and Dectin-1 mediated noncanonical NF-kB signaling were significantly associated with the proteins that could discriminate OA from NOA. Comparison with 2 transcriptome datasets revealed 278 and 55 co-differentially expressed proteins/genes with statistically significant positive correlation. Gene expression analysis by qPCR of 6 genes (H1-6, RANBP1, TKTL2, TKTL1, H2BC1, and ACTL7B) with the highest discriminatory power on protein level and the same regulation trend with transcriptomic datasets, confirmed proteomics results. In summary, our results suggest some underlying pathways in azoospermia and broaden the range of potential novel candidates for diagnosis. SIGNIFICANCE: Using a comparative proteomics approach on testicular tissue we have identified several pathways associated with azoospermia and a number of testis-specific and germ cell-specific proteins that have the potential to pinpoint the type of spermatogenesis failure. Furthermore, comparison with transcriptomics datasets based on genome-wide gene expression analyses of human testis specimens from azoospermia patients identified proteins that could discriminate between obstructive and non-obstructive azoospermia subtypes on both protein and mRNA levels. Up to our knowledge, this is the first integrated comparative analysis of proteomics and transcriptomics data from testicular tissues. We believe that the data from our study contributes significantly to increase the knowledge of molecular mechanisms of azoospermia and pave the way for new investigations in regards to non-invasive diagnosis.

Abstract
Radiotherapy, a popular cancer management procedure, negatively impacts reproductive health particularly by reducing the fertility potential. The purpose of this study was to analyze the research trend in radiotherapy associated with male infertility over the past 20 years (2000-May 2021). SCOPUS database was used to retrieve relevant scientometric data (publication per year, affiliation, journals, countries, type of document and area of research) for different subgenres of radiotherapy and male infertility. A total of 275 articles were published related to radiotherapy and male infertility, with the United States being the most dominant country in research output in this field. Radiotherapy and male infertility research have shown positive growth over the last two decades. In-depth analysis revealed that publications (n) related to radiotherapy and male infertility research mainly focused its impact on semen parameters (n = 155) and fertility preservation techniques (n = 169). Our scientometric results highlight a limited research focus on the field of radiotherapy and its impact on male reproductive hormones. Furthermore, a significant lack of research was noticed in the area of omics and male reproductive organs linked to radiotherapy. Substantial research is warranted to further decipher the effect of radiotherapy, at molecular level, leading to male infertility.

Comprehensive Analysis of Global Research on Human Varicocele: A Scientometric Approach. World J Mens Health 2022; 40:636-652. [PMID: 35118839 PMCID: PMC9482861 DOI: 10.5534/wjmh.210202] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 10/13/2021] [Accepted: 10/25/2021] [Indexed: 12/05/2022] Open
Abstract
Purpose This study provides a comprehensive analysis of research trends on the etiology, mechanisms, potential risk factors, diagnosis, prognosis, surgical and non-surgical treatment of varicocele, and clinical outcomes before and after varicocele repair. Materials and Methods Varicocele studies published between 1988 and 2020 were retrieved from the Scopus database on April 5, 2021. Original studies on human varicocele were included, irrespective of language. Retrieved articles were manually screened for inclusion in various sub-categories. Bibliometric data was subjected to scientometric analysis using descriptive statistics. Network, heat and geographic mapping were generated using relevant software. Results In total, 1,943 original human studies on varicocele were published. These were predominantly from the northern hemisphere and developed countries, and published in journals from the United States and Germany. Network map analysis for countries showed several interconnected nodal points, with the USA being the largest, and Agarwal A. from Cleveland Clinic, USA, being a center point of worldwide varicocele research collaborations. Studies of adolescents were underrepresented compared with studies of adults. Studies on diagnostic and prognostic aspects of varicocele were more numerous than studies on varicocele prevalence, mechanistic studies and studies focusing on etiological and risk factors. Varicocele surgery was more investigated than non-surgical approaches. To evaluate the impact of varicocele and its treatment, researchers mainly analyzed basic semen parameters, although markers of seminal oxidative stress are being increasingly investigated in the last decade, while reproductive outcomes such as live birth rate were under-reported in the literature. Conclusions This study analyzes the publication trends in original research on human varicocele spanning over the last three decades. Our analysis emphasizes areas for further exploration to better understand varicocele’s impact on men’s health and male fertility.

Beovich B, Olaussen A, Williams B. A bibliometric analysis of paramedicine publications using the Scopus database: 2010-2019. Int Emerg Nurs 2021; 59:101077. [PMID: 34571451 DOI: 10.1016/j.ienj.2021.101077] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Revised: 08/17/2021] [Accepted: 08/24/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Paramedicine is an evolving profession undergoing increases in scholarly activity and peer-reviewed publications. This study aims to complete the first extensive bibliometric examination of the worldwide paramedicine literature. METHOD Scopus was utilised to search for paramedicine-based articles published in peer-reviewed journals between 2010 and 2019 inclusive. The included articles were examined for citation count, journal, journal quartile, country of origin, university affiliation, collaboration, and topic. RESULTS Paramedicine-based publications have steadily increased and are predominantly published in prehospital or emergency healthcare journals. The majority of highly cited authors were located in Australia; however, only one of these authors was identified as a paramedic. Monash University (Australia) was the most productive institution (11.7% of total articles) and collaboration was mostly within national boundaries (53.2%). CONCLUSION This study demonstrates the progressive increase in paramedic scholarly activity over the past decade. Although a large number of articles originate from two countries (Australia and the USA) and one university, numerous nations and institutions are contributing to this body of knowledge. The growing literature base is indicative of the evolution of paramedicine; however, the high level of non-paramedic authors suggests the opportunity for further scholarly development within the paramedic discipline.

Abstract
Metabolic syndrome (MetS) and infertility are two afflictions with a high prevalence in the general population. MetS is a global health problem increasing worldwide, while infertility affects up to 12% of men. Despite the high prevalence of these conditions, the possible impact of MetS on male fertility has been investigated by a few authors only in the last decade. In addition, underlying mechanism(s) connecting the two conditions have been investigated in few preclinical studies. The aim of this review is to summarize and critically discuss available clinical and preclinical studies on the role of MetS (and its treatment) in male fertility. An extensive Medline search was performed identifying studies in the English language. While several studies support an association between MetS and hypogonadism, contrasting results have been reported on the relationship between MetS and semen parameters/male infertility, and the available studies considered heterogeneous MetS definitions and populations. So far, only two meta-analyses in clinical and preclinical studies, respectively, evaluated this topic, reporting a negative association between MetS and sperm parameters, testosterone and FSH levels, advocating, however, larger prospective investigations. In conclusion, a possible negative impact of MetS on male reproductive potential was reported; however, larger studies are needed.

Biomed Pharmacother 2021; 133:111085. [PMID: 33378981 DOI: 10.1016/j.biopha.2020.111085] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 11/06/2020] [Accepted: 11/28/2020] [Indexed: 12/12/2022] Open
Abstract
Obesity is a significant global health and socio-economic challenge, and considered an important risk factor for poor health outcomes including male reproductive dysfunction and infertility. As excess adiposity causes testicular dysfunction and infertility, novel therapeutic strategies require investigation. Nigella sativa (Ns) seed oil and metformin have both demonstrated a potential positive effect on obesity, although both remain poorly investigated in male fertility. Therefore, this study aimed to determine the effect of Ns oil and metformin on total body weight (TBW), mitochondrial membrane potential (MMP), serum testosterone and semen parameters in an obese animal model. Wistar rats (n = 54) were divided into six groups: normal chow (NC), high sugar diet (HSD) only, HSD and saline, HSD and metformin (75 mg/Kg/day), HSD and Ns (200 mg/Kg/day) (NS200), HSD and Ns (400 mg/Kg/day) (NS400). Intervention was force fed for the last 8 weeks of the 14 weeks dietary exposures. Results showed that the HSD increased TBW (P = 0.001) and reduced sperm concentration (P = 0.013) and progressive motility (P = 0.009) compared to the NC group. Metformin, NS200 and NS400 improved TBW (P = 0.035, P = 0.006 and P = 0.005, respectively) and testosterone (P < 0.001) compared to the HSD saline group, where metformin and NS400 improved sperm concentration (P < 0.001 and P = 0.049, respectively) and MMP (P < 0.001). There were no changes in sperm motility and viability for all experimental exposures, although NS400 (P = 0.047) negatively affected sperm viability. Metformin and Ns may be novel treatment options in obesity-induced infertility, although a potential negative impact on viability is cautioned for high dose Ns. These results warrant further investigation of Ns and Metformin for the management of obese infertile males.

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
Proteomics and metabolomics are emerging as promising tools to investigate the molecular mechanisms associated with male infertility. Proteins and metabolites play a pivotal role in regulating the molecular pathways associated with physiological functions of spermatozoa. Semen analysis, physical examination and laboratory work up cannot identify the etiology of infertility in 30%-40% of cases, which are classified as idiopathic. Therefore, the application of proteomics and metabolomics in the field of andrology will aid to overcome the limitations of the standard semen analysis. Understanding the molecular pathways associated with male infertility will help in planning ad hoc treatments, contributing to the clinical management of infertile patients. In this review, proteomics and metabolomics studies on spermatozoa and seminal plasma are discussed with a focus on molecular biomarkers associated with male infertility-related conditions.

Abstract
Alongside an increasing prevalence of couple and male infertility, evidence suggests there is a global declining trend in male fertility parameters over the past few decades. This may, at least in part, be explained through detrimental lifestyle practices and exposures. These include alcohol and tobacco consumption, use of recreational drugs (e.g., cannabis, opioids and anabolic steroids), poor nutritional habits, obesity and metabolic syndrome, genital heat stress (e.g., radiation exposure through cell phones and laptops, prolonged periods of sitting, tight-fitting underwear and recurrent hot baths or saunas), exposure to endocrine-disrupting chemicals (e.g., pesticide residue, bisphenol A, phthalates and dioxins) and psychological stress. This review discusses these lifestyle practices and the current evidence associated with male infertility. Furthermore, known mechanisms of action are also discussed for each of these. Common mechanisms associated with a reduction in spermatogenesis and/or steroidogenesis due to unfavourable lifestyle practices include inflammation and oxidative stress locally or systemically. It is recommended that relevant lifestyle practices are investigated in clinical history of male infertility cases, particularly in unexplained or idiopathic male infertility. Appropriate modification of detrimental lifestyle practices is further suggested and recommended in the management of male infertility.

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
BACKGROUND This article describes the research trends in sperm DNA fragmentation (SDF) over the past 20 years (1999-2018) using a scientometric approach. METHODS A stepwise approach was adopted to retrieve scientometric data (articles per year, authors, affiliations, journals, countries) from Scopus and analyze the publication pattern of SDF with reference to key areas of research in the field of Andrology. RESULTS A total of 2121 articles were retrieved related to SDF. Our data revealed an increasing research trend in SDF (n = 33 to n = 173) over the past 20 years (R2 = 0.894). Most productive country in publications was the USA (n = 450), while Agarwal A. (n = 129) being the most productive author. Most of the articles in SDF were primarily focused on lifestyle (n = 157), asthenozoospermia (n = 135) and varicocele (130). Mechanistic studies on SDF were published twice as much as prognostic/diagnostic studies, with significant emphasis on oxidative stress. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) was the most widely used technique to evaluate SDF. Publications on SDF related to assisted reproductive techniques also showed a linear increasing trend (R2 = 0.933). CONCLUSIONS Our analysis revealed an increasing trend in SDF publications predominantly investigating lifestyle, asthenozoospermia and varicocele conditions with TUNEL being the most widely used technique. A substantial increase in research is warranted to establish SDF as prognostic/diagnostic parameter to evaluate clinical scenarios and ART outcomes.

Abstract
Plagiarism is a common form of academic misconduct that extensively jeopardises the quality of scientific publication. The purpose of this study is to determine the extent of plagiarism in the most influential andrology articles. A total of 77 highly cited andrology articles were analysed for their similarity index using iThenticate and Turnitin. The articles were categorised based on the year (before and on/after 2000) and type of publication (review and research articles), and the similarity indices were compared. Furthermore, the analysed articles were categorised based on the level of similarity using an arbitrary similarity index range (low: ≤10, moderate: 11-20, high: 21-50 and very high: >50) and average incidence rate (%) was determined. Our analysis revealed a higher percentage of the similarity indices for reviews than research articles. We noticed a higher similarity index for articles published on/after 2000 than those published before. The majority of the influential articles in the field of andrology showed a low similarity index, while some articles exhibited moderate to high levels of similarity. These findings support the need for the development of similarity index guidelines as a major pre-requisite for establishing a more transparent and efficient system to address plagiarism in scientific publications.

Abstract
Semen quality plays a pivotal role in maintaining healthy fertilizing ability of spermatozoa. Male infertility is a rising global problem with an increasing declining in male semen quality among men living in Africa, Europe, North American, and Asia. Though the sperm acquire proactive mechanisms during spermatogenesis and their epididymal maturation, they still remain viable for toxic insult. Declining semen quality is a major contributor to infertility. Studies have postulated that different factors, such as exposure to pesticides, industrial chemicals, heavy metals, obesity, alcoholism, tobacco smoking, sedentary lifestyles, poor nutrient intake, oxidative stress, physiological factors, genetic factors can influence male fertility. Routine semen analysis and assays for sperm chromatin integrity are the most widely utilized and best studied adjunctive diagnostics in male infertility. Over the years, scientists have developed different treatment options for male infertility. Male infertility with known etiology can be treated successfully, but other causes like genetic factors require pragmatic approaches. This article summarizes protective mechanisms of spermatogenesis, causes, diagnosis, and both modern and traditional treatment approaches of male infertility. Further, this article highlights present issues and direction for future exploration of the male infertility problem.
