RESUMEN

Peyronie's disease (PD) is a common benign condition characterized by superficial fibrosis and scar formation at the tunica albuginea of the penis, eventually leading to penile curvature. It is believed that penile micro-traumas during intercourse and subsequent activation of inflammatory processes constitute the pathogenetic basis of the disease. Routinely, PD is divided into acute and chronic phases, with pain during erection or flaccid state being the hallmark of the former. Surgical intervention should be avoided during the acute phase, as the risk of recurrence or progression of penile deformity during this stage might affect the optimal outcomes of the procedure. During this stage, many conservative treatment options have been suggested, including oral, topical, and intralesional therapies, extracorporeal shock wave therapy (ESWT), and penile traction therapy (PTT). Currently, the optimal treatment consists of a combined treatment strategy with phosphodiesterase type 5 inhibitors (PDE5Is), ESWT for pain management, PTT, and intralesional therapies. Large, well-designed randomized controlled trials (RCTs) are necessary to further elucidate the most efficient treatment option for acute phase PD.

RESUMEN

This article commemorates the 100th anniversary of the first issue of Cell & Tissue Research (CTR), the longest-running active journal dedicated to cell biology. Reflecting the significant contributions of spermatology and embryology to the early days of cell biology, the majority of articles in CTR's inaugural issue centered on plant and animal sperm cells. A brief synopsis of these articles provides a launching point for revisiting 100 years of research on the male germ cells and fertility in humans and animals and offers a perspective on the current state and future directions of the andrology field. Early technological advances in light and electron microscopy enabled descriptive studies that ushered in the era of mechanistic, biochemistry-based inquiry focused on the understanding of physiological sperm processes such as sperm capacitation, acrosomal exocytosis, and sperm-egg interactions. In the last 20 years, progress in flow cytometry, cell imaging, and omics revealed new information on sperm proteome, transcriptome, metabolome, and overall phenome of fertile and infertile spermatozoa. Going back to the journal's roots, recent advances in male germ cell isolation, transplantation, modification, and cryopreservation have been discussed on the pages of CTR. Newest trends such as gene editing and artificial intelligence/machine learning are now making inroads into andrological inquiry and assisted reproductive therapy of male infertility.

RESUMEN

Despite that the SARS-CoV-2 pandemic has been controlled, it has affected a large proportion of the population, raising some concerns about potential sequelae in men at reproductive age. To contribute to the clarification of this issue, we performed a retrospective study comparing semen parameters values before and after confirmed SARS-CoV-2 infection in a large cohort of infertile men, compared to a control group that did not undergo SARS-CoV-2 infection. Wilcoxon test on paired samples and general linear regression model showed that SARS-CoV-2 infection has a detrimental effect on semen volume values (p < 0.005). However, semen volume seems to be significantly lower only during the first spermatogenic cycle after SARS-COV-2 infection (p < 0.005) and mainly in unvaccinated patients (p < 0.05). In addition, we detected alterations in progressive motility in patients infected with the alpha SARS-COV-2 strain (p < 0.05). In conclusion, our results show that although SARS-CoV-2 has a small effect on semen volume and sperm motility in infertile men, depending on the infectious strain or vaccination status, pre-infection values of semen parameters appear to be restored over one spermatogenic cycle after infection.

RESUMEN

PURPOSE: Andrological pathologies in the adulthood are often the results of conditions that originate during childhood and adolescence and sometimes even during gestation and neonatal period. Unfortunately, the reports in the literature concerning pediatric andrological diseases are scares and mainly concerning single issues. Furthermore, no shared position statement are so far available. METHODS: The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving the Italian Society of Pediatric Endocrinology and Diabetology (SIEDP) to provide an updated guideline on the diagnosis and management of andrological disorders from childhood and adolescence to transition age. Derived recommendations were based on the grading of recommendations, assessment, development, and evaluation (GRADE) system. RESULTS: A literature search of articles in English for the term "varicoceles", "gynecomastia", "fertility preservation", "macroorchidism", "precocious puberty" and "pubertal delay" has been performed. Three major aspects for each considered disorder were assessed including diagnosis, clinical management, and treatment. Recommendations and suggestions have been provided for each of the mentioned andrological disorders. CONCLUSIONS: These are the first guidelines based on a multidisciplinary approach that involves important societies related to the field of andrological medicine from pediatric to transition and adult ages. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving andrological and general health of the transitional age.

RESUMEN

Azoospermia, the absence of sperm cells in semen, affects around 15% of infertile males. Sertoli cell-only syndrome (SCOS) is the most common pathological lesion in the background of non-obstructive azoospermia and is characterised by the complete absence of germinal epithelium, with Sertoli cells exclusively present in the seminiferous tubules. Studies have shown a correlation between successful spermatogenesis and male fertility with lipid composition of spermatozoa, semen, seminal plasma or testis. The aim of this research was to discover the correlation between the Johnsen scoring system and phospholipid expressions in testicular cryosections of SCOS patients. MALDI imaging mass spectrometry is used to determine spatial distributions of molecular species, such as phospholipids. Phosphatidylcholines (PCs), phosphatidylethanolamines (PEs) and sphingomyelins (SMs) are the most abundant phospholipids in mammalian cells and testis. SMs, the structural components of plasma membranes, are crucial for spermatogenesis and sperm function. Plasmalogens, are unique PCs in testis with strong antioxidative properties. This study, using imaging mass spectrometry, demonstrates the local distribution of phospholipids, particularly SMs, PCs, plasmalogens and PEs in human testicular samples with SCOS for the first time. This study found a strong relationship between the Johnsen scoring system and phospholipid expression levels in human testicular tissues. Future findings could enable routine diagnostic techniques during microTESE procedures for successful sperm extraction.

RESUMEN

IMPORTANCE: Findings from several high profile meta-analyses have raised concerns about an ongoing global decline in sperm concentration and male fertility. However, these studies exhibit considerable heterogeneity in key variables including study population, methodology, fertility status, and geographic region. OBJECTIVE: To perform a systematic review and meta-analysis exploring temporal trends in sperm concentration among fertile men and men unselected for fertility status in the United States. DATA SOURCES: A literature search performed in Scopus and PubMed databases for studies published between 1970 and 2023. Additional studies were included from citations of prior global meta-analyses and reviews evaluating temporal trends in sperm count. STUDY SELECTION AND SYNTHESIS: Studies were included if they presented original data on sperm concentration in US men without known infertility from 1970 to 2023. Aggregate data were assessed across all study populations, with additional subgroup analyses stratified by fertility status and US region. MAIN OUTCOMES: Weighted generalized linear models were generated to evaluate the association between mean sperm concentration and sample collection year. RESULTS: A total of 874 articles were screened, with 58 meeting the inclusion criteria. These represented 75 unique study populations totaling 11,787 men in the United States. Across all study populations, no change in sperm concentration was observed between 1970 and 2018 in unadjusted models (ß = 0.14 million/mL per year). When adjusting for US region, no statistically significant decline in sperm concentration was seen. When adjusting for both region and fertility status, a modest annual decline was observed to meet statistical significance (ß = -0.35 million/mL per year). Of the 49 study populations reporting adequate data to determine mean total sperm count, there was a significant increase in total sperm count of 2.9 million per year between 1970 and 2018. Subgroup analysis found no statistically significant change in mean sperm concentration among any US census region or fertility status cohort. CONCLUSION AND RELEVANCE: In contrast to prior global studies, this analysis suggests no clinically significant decline in sperm concentration among confirmed fertile men and the general male US population without known infertility. Although these findings provide some reassurance against a widespread rapid decline, further studies are necessary to better understand this important topic.

RESUMEN

We aimed to assess the reliability of Chat Generative Pre-training Transformer (ChatGPT)'s andrology information and its suitability for informing patients and medical students accurately about andrology topics. We presented a series of systematically organized frequently asked questions on andrology topics and sentences containing strong recommendations from the European Association of Urology (EAU) Guideline to ChatGPT-3.5 and 4.0 as questions. These questions encompassed Male Hypogonadism, Erectile Dysfunction and Sexual Desire Disorder, Disorders of Ejaculation, Penile Curvature and Penile Size Abnormalities, Priapism, and Male Infertility. Two expert urologists independently evaluated and assigned scores ranging from 1 to 4 to each response based on its accuracy, with the following ratings: (1) Completely true, (2) Accurate but insufficient, (3) A mixture of accurate and misleading information, and (4) Completely false. A total of 120 questions were included in the study. Among these questions, 50.0% received a grade of 1 (completely correct) (55.4% for 4.0 version). The combined rate of correct answers (grades 1 and 2) was 85.2% for frequently asked questions (88.8% for 4.0 version) and 81.5% for questions obtained from the guideline. The rate of completely incorrect answers (grade 4) was 1.8% for frequently asked questions (0% for 4.0 version) and 5.2% for questions based on strong recommendations. The response rate of version 4.0 to questions created from sentences containing strong recommendations from the EAU guideline was the same as version 3.5. ChatGPT provided satisfactory answers to the questions asked, although some responses lacked completeness. It may be beneficial to utilize ChatGPT under the guidance of a urologist to enhance patients' comprehension of their andrology issues.

RESUMEN

PURPOSE: The continuous improvement and development of fertility care, internationally, requires ongoing monitoring of current delivery processes and outcomes in clinical practice. This descriptive and exploratory mixed-methods study was conducted in eight countries (Brazil, China, France, Germany, Italy, Mexico, Spain and the United Kingdom) to assess the unmet needs of fertility patients (male and female), and existing challenges, barriers and educational gaps of physicians and laboratory specialists involved in human fertility care during the COVID-19 pandemic. MATERIALS AND METHODS: The study was deployed sequentially in two phases: 1) in-depth 45-minute semi-structured interviews (n=76), transcribed, coded and thematically analysed using an inductive reasoning approach, 2) an online survey (n=303) informed by the findings of the qualitative interviews, face validated by experts in reproductive medicine, and analysed using descriptive and inferential statistical methods. RESULTS: The integrated results of both phases indicated numerous areas of challenges, including: 1) investigating male-related infertility; 2) deciding appropriate treatment for men and selective use of assisted reproductive technology; and 3) maintaining access to high-quality fertility care during a pandemic. CONCLUSIONS: The paper presents a reflective piece on knowledge and skills that warrant ongoing monitoring and improvement amongst reproductive medicine healthcare professionals amidst future pandemics and unanticipated health system disruptions. Moreover, these findings suggest that there is an additional need to better understand the required changes in policies and organizational processes that would facilitate access to andrology services for male infertility and specialized care, as needed.

RESUMEN

OBJECTIVE: New indices of dyslipidemia, such as the Atherogenic Index of Plasma (AIP) or Castelli Risk Index I and II (CR-I/II), have been tested to predict erectile dysfunction (ED). The aim of this study was to assess the role of these lipidic scores in predicting severe ED and erectile function (EF) worsening in patients who underwent robot-assisted radical prostatectomy (RARP). METHODS: Data from 1249 prostate cancer patients who underwent RARP at our single tertiary academic referral center from September 2021 to April 2023 were reviewed. RARP patients with a complete lipid panel were included in the final analysis. Two independent multivariable logistic regression models (LRMs) were fitted to identify predictors of ED severity and worsening in RARP patients. RESULTS: Among the 357 RARP patients, the median age was 70 (interquartile range [IQR]: 65-74), and the median BMI was 28.4 (IQR: 26-30.4). According to the preoperative IIEF5, 115 (32.2%), 86 (24.5%), 26 (7.3%), and 40 (11.2%) were mild, mild-moderate, moderate, and severe ED patients, respectively. After multivariable LRMs predicting severe ED, only the nerve-sparing (NS) approach (odds ratio [OR]: 0.09) as well as the preoperative IIEF5 score (OR: 0.32) were independent predictors (p < 0.001). After LRMs predicting EF worsening, only preoperative IIEF5 was an independent predictor (OR: 1.42, p < 0.001). CONCLUSION: The power of novel lipidic scores in predicting severe ED and EF worsening in RARP patients was low, and they should not be routinely applied as a screening method in this patient subgroup. Only preoperative IIEF5 and nerve-sparing approaches are relevant in EF prediction after RARP.

RESUMEN

Background: The World Health Organization (WHO) recommends reporting sperm morphology in a standard semen analysis. However, the clinical utility and prognostic value of morphology is often debated. Methods: We reviewed and summarized studies that assessed both the benefits and limitations of sperm morphology in the context of natural fertility, assisted reproductive technologies, and recurrent pregnancy loss. We additionally describe possible environmental and anatomical etiologies of teratozoospermia. Results: Sperm morphology evaluation has continuously evolved since the release of the first WHO manual in 1980. Initially, several large studies reported significant inverse associations between fertility outcomes and teratozoospermia. Most recent studies, however, fail to show an association between sperm morphology and natural or assisted fertility outcomes. Conclusion: Sperm morphology analysis may have limited diagnostic and prognostic value. Providers should be aware of these limitations when counseling or managing infertile patients.

RESUMEN

INTRODUCTION: Andrology and urogenital reconstruction are emerging disciplines in French urology. The aim of our study was to evaluate the evolution of andrological surgical procedures over the period 2013-2022 using national data. MATERIALS AND METHODS: We collected national common classification of medical acts (CCAM) coding data for all procedures involving andrological surgery from the Scansanté internet platform set up by the Technical Agency for Information on Hospitalisation, which collects prospectively from healthcare structures all procedures coded according to CCAM coding. All surgical procedures in andrology were selected. The inclusion period extended from 2013 to 2022. RESULTS: In 10 years, the number of vasectomies has increased tenfold, with 29,890 cases in 2022. Vaso-vasostomies remain marginal, with 80 cases per year. Trans-identity surgeries are rising sharply. Vaginoplasties have multiplied by 4 (333 in 2022) and masculinising surgeries have multiplied by 10 (234 in 2022). Penile prosthesis surgery has increased slightly over 10 years. The number of testicular biopsies has remained stable over time, as has the number of surgeries for curvature of the penis. CONCLUSION: Two andrological surgeries are showing very strong growth: vasectomy and transgender surgery. The emergence of these 2 activities is linked to societal aspirations. Urologists need to be trained to meet this demand. NIVEAU DE PREUVE: Grade 4.

RESUMEN

BACKGROUND: The widespread interest in male reproductive health (MRH), fueled by emerging evidence, such as the global decline in sperm counts, has intensified concerns about the status of MRH. Consequently, there is a pressing requirement for a strategic, systematic approach to identifying critical questions, collecting pertinent information, and utilizing these data to develop evidence-based strategies. The methods for addressing these questions and the pathways toward their answers will inevitably vary based on the variations in cultural, geopolitical, and health-related contexts. To address these issues, a conjoint ESHRE and Male Reproductive Health Initiative (MRHI) Campus workshop was convened. OBJECTIVE AND RATIONALE: The three objectives were: first, to assess the current state of MRH around the world; second, to identify some of the key gaps in knowledge; and, third, to examine how MRH stakeholders can collaboratively generate intelligent and effective paths forward. SEARCH METHODS: Each expert reviewed and summarized the current literature that was subsequently used to provide a comprehensive overview of challenges related to MRH. OUTCOMES: This narrative report is an overview of the data, opinions, and arguments presented during the workshop. A number of outcomes are presented and can be summarized by the following overarching themes: MRH is a serious global issue and there is a plethora of gaps in our understanding; there is a need for widespread international collaborative networks to undertake multidisciplinary research into fundamental issues, such as lifestyle/environmental exposure studies, and high-quality clinical trials; and there is an urgent requirement for effective strategies to educate young people and the general public to safeguard and improve MRH across diverse population demographics and resources. LIMITATIONS REASONS FOR CAUTION: This was a workshop where worldwide leading experts from a wide range of disciplines presented and discussed the evidence regarding challenges related to MRH. While each expert summarized the current literature and placed it in context, the data in a number of areas are limited and/or sparse. Equally, important areas for consideration may have been missed. Moreover, there are clear gaps in our knowledge base, which makes some conclusions necessarily speculative and warranting of further study. WIDER IMPLICATIONS: Poor MRH is a global issue that suffers from low awareness among the public, patients, and heathcare professionals. Addressing this will require a coordinated multidisciplinary approach. Addressing the significant number of knowledge gaps will require policy makers prioritizing MRH and its funding.

RESUMEN

PURPOSE: Platelet-rich plasma (PRP) as a regenerative therapy has gained interest in the field of andrology for the treatment of erectile dysfunction (ED) and Peyronie's disease (PD). This systematic review aims to critically evaluate the current evidence on the use of PRP for these conditions. METHODS: We performed a systematic literature search according to the PRISMA guidelines using PubMed and Scopus databases in December 2023. Studies were included if they evaluated the effect of PRP therapy for ED or PD in humans. RESULTS: We identified 164 articles, 17 of which were included, consisting of 11 studies on ED, 5 studies on PD, and 1 study on both. We included four randomized controlled trials, 11 prospective cohort studies, and three retrospective cohort studies including a total of 1099 patients. The studies on ED and PD generally showed small to moderate benefits with mild and transient side effects and no major adverse events were reported. General limitations included variations in PRP protocols, small sample sizes, short follow-up periods, and lack of control groups except in the three randomized trials on ED and the one on PD. CONCLUSION: The literature on PRP therapy in andrology is limited and difficult to interpret due to variations in protocols and methodological drawbacks. Further research is necessary to determine the optimal preparation and treatment protocols for PRP therapy and clarify its effectiveness in andrology.

RESUMEN

The evolving prevalence of anabolic androgenic steroids (AAS) abuse among nonathletes is alarming because of the known harm to an individual's health. Among the adverse effects of AAS abuse, male infertility and sexual dysfunction have been often reported in the literature, but little is known regarding its actual prevalence, possible underpinning mechanisms, and potential treatments either during or post-AAS usage. Thus, the current narrative review summarizes the state-of-art regarding the effects of AAS on male fertility and sexual function. Evidence was gathered from the latest reviews and recent original studies, specifically from prospective cohorts and clinical trials, ultimately resulting in five main topics of discussion. First, AAS usage is briefly characterized by its historical background, main physiological mechanisms, and the most frequently used AAS substances. Second, data on the prevalence of AAS-induced male infertility and sexual dysfunction are described. Third, some new insights on possible underpinning mechanisms of AAS-induced male infertility and sexual dysfunction are thoroughly discussed, with particular attention to histological data derived from animal models and the latest insights from prospective cohorts in humans. Fourth, the potential treatments during and after the AAS usage are presented, highlighting the odds of resolving male infertility and sexual dysfunction. Fifth, future directions on this topic are discussed, focusing on the methodological robustness of scientific studies.

RESUMEN

OBJECTIVE: AI-derived language models are booming, and their place in medicine is undefined. The aim of our study is to compare responses to andrology clinical cases, between chatbots and andrologists, to assess the reliability of these technologies. MATERIAL AND METHOD: We analyzed the responses of 32 experts, 18 residents and three chatbots (ChatGPT v3.5, v4 and Bard) to 25 andrology clinical cases. Responses were assessed on a Likert scale ranging from 0 to 2 for each question (0-false response or no response; 1-partially correct response, 2- correct response), on the basis of the latest national or, in the absence of such, international recommendations. We compared the averages obtained for all cases by the different groups. RESULTS: Experts obtained a higher mean score (m=11/12.4 σ=1.4) than ChatGPT v4 (m=10.7/12.4 σ=2.2, p=0.6475), ChatGPT v3.5 (m=9.5/12.4 σ=2.1, p=0.0062) and Bard (m=7.2/12.4 σ=3.3, p<0.0001). Residents obtained a mean score (m=9.4/12.4 σ=1.7) higher than Bard (m=7.2/12.4 σ=3.3, p=0.0053) but lower than ChatGPT v3.5 (m=9.5/12.4 σ=2.1, p=0.8393) and v4 (m=10.7/12.4 σ=2.2, p=0.0183) and experts (m=11.0/12.4 σ=1.4,p=0.0009). ChatGPT v4 performance (m=10.7 σ=2.2) was better than ChatGPT v3.5 (m=9.5, σ=2.1, p=0.0476) and Bard performance (m=7.2 σ=3.3, p<0.0001). CONCLUSION: The use of chatbots in medicine could be relevant. More studies are needed to integrate them into clinical practice.

RESUMEN

Benign prostatic hyperplasia (BPH) is an androgen-related non-neoplastic enlargement of the prostate gland that commonly affects both reproductive capabilities and the general health of intact dogs. The subclinical form of BPH can be challenging to diagnose due to a lack of clinical signs, even if rectal palpation is performed. Left untreated, this condition poses risks to the dogs' health and breeding status. This study, involving 65 male dogs, aimed to investigate subclinical BPH through rectal palpation, ultrasonography, and analysis of canine prostatic-specific esterase (CPSE). Of the participants, 35 had subclinical BPH, and 30 served as a healthy control group. Dogs suspected of subclinical BPH, as determined by examination results from ultrasonography and CPSE analysis, underwent fine needle aspiration (FNA) guided by ultrasound to enhance diagnostic precision. Findings revealed distinct differences in rectal palpation and ultrasonography between subclinical BPH and healthy dogs. This study established diagnostic thresholds based on prostatic volume and CPSE values and proposed new thresholds for subclinical BPH. Additionally, results showed that prostate gland volume depended on the weight and the age of the dog. In conclusion, early detection of this condition is possible through various examinations, such as changes in ultrasound features, CPSE levels, and rectal palpation. All together, these methods can aid practitioners in early detection of BPH and assist with scheduling screening programs for dogs, ultimately promoting their overall health and reproductive well-being. In conclusion, we advocate for routine, non-invasive prostate screenings in breeding males, underlining the effectiveness of a combination of various multiple techniques for early subclinical BPH detection.
