RESUMO

The 15th Network of Young Researchers in Andrology (NYRA) meeting, held at the Palace de Caux, Switzerland, served as a valuable platform to disseminate cutting-edge research and facilitate interactions among early-career researchers and trainees in andrology from around the world. Preceding the 22nd European Testis Workshop, the 2-day event brought together participants from a variety of countries to discuss a range of topics pertaining to men's reproductive health and biology. Specific focuses included piRNAs in mammalian reproduction, biomolecules enhancing sperm physiology, advances in in vitro spermatogenesis, reproductive strategies across species, and career development. A dedicated 'scientific speed-dating' social event also stood out, encouraging cross-disciplinary collaborations and strengthening ties within the scientific community. The high participation rate of the meeting highlighted its value in connecting the andrology community. Finally, the announcement of NYRA's merger with the European Academy of Andrology (EAA) marked a pivotal moment, enabling NYRA to support young researchers while collaborating with the EAA to advance andrology research. The 15th NYRA meeting played a crucial role in enhancing knowledge dissemination and andrology research, empowering young researchers, and addressing key challenges in male infertility.

RESUMO

Testing for AZoospermia Factor (AZF) deletions of the Y chromosome is a key component of the diagnostic workup of azoospermic and severely oligozoospermic men. This revision of the 2013 European Academy of Andrology (EAA) and EMQN CIC (previously known as the European Molecular Genetics Quality Network) laboratory guidelines summarizes recent clinically relevant advances and provides an update on the results of the external quality assessment program jointly offered by both organizations. A basic multiplex PCR reaction followed by a deletion extension analysis remains the gold-standard methodology to detect and correctly interpret AZF deletions. Recent data have led to an update of the sY84 reverse primer sequence, as well as to a refinement of what were previously considered as interchangeable border markers for AZFa and AZFb deletion breakpoints. More specifically, sY83 and sY143 are no longer recommended for the deletion extension analysis, leaving sY1064 and sY1192, respectively, as first-choice markers. Despite the transition, currently underway in several countries, toward a diagnosis based on certified kits, it should be noted that many of these commercial products are not recommended due to an unnecessarily high number of tested markers, and none of those currently available are, to the best of our knowledge, in accordance with the new first-choice markers for the deletion extension analysis. The gr/gr partial AZFc deletion remains a population-specific risk factor for impaired sperm production and a predisposing factor for testicular germ cell tumors. Testing for this deletion type is, as before, left at the discretion of the diagnostic labs and referring clinicians. Annual participation in an external quality control program is strongly encouraged, as the 22-year experience of the EMQN/EAA scheme clearly demonstrates a steep decline in diagnostic errors and an improvement in reporting practice.

RESUMO

BACKGROUND: Medical guidelines are defined as practical orientation and decision-making aids; they are legally defined as noncommittal recommendations. International guidelines are written in very general terms, especially in the case of heterogeneous clinical pictures (e.g., vesicoureteral reflux). OBJECTIVE: Could national guidelines based on international recommendations become authoritative as specific treatment recommendations for the various specialist groups? MATERIALS AND METHODS: The value of international and national guidelines was assessed using the example case history of a child affected with vesicoureteral reflux. RESULTS: Due to the various therapeutic possibilities according to various guidelines, the child received unfavorable, incongruent, delayed, and repeated unsuccessful attempts with different treatment regimes CONCLUSION: Due to the nonbinding nature of general guidelines, there is a risk of suboptimal therapy. National guidelines aimed at individualized treatment recommendations should aim for higher medical and legal status.

RESUMO

Introduction: The sexual life of a couple is a dynamic entity, in which the two influence each other mutually, thus the existence of female sexual dysfunction (FSD) can influence the treatment of the man who seeks clinical help. Identify sexual dysfunction in female partners of patients attending an andrology clinic may provide a therapeutic opportunity. The authors aim to assess proportion of FSD in this population by comparison with a control group. Material and methods: A longitudinal study over 12 months timespan. The female partners of patients attending the andrology clinic participating in the study (study group – SG) completed the Female Sexual Function Index (FSFI), as did the women serving as controls (control group – CG). Further data such as age, duration and quality of the relationship and previous relationships was also collected. Results: Of the 30 women included in the SG, 14 (46.6%) considered that their current sex life was worse than in previous relationships. Of the 20 women in the CG, 60% considered that their current sex life was better. In the SG, 22 (73.3%) had FSD, with a mean score in the FSFI of 20.5, whereas only 3 women in the CG (15%) had FSD, with a mean score of 30.7 (p<0.01). Conclusions: Our study demonstrated that the proportion of FSD in female partners of patients attending an andrology clinic is significantly higher than control group. FSD treatment should be considered as a therapeutic opportunity for the couple in this setting. (AU)


Introducción: La vida sexual de una pareja es una entidad dinámica, en la que ambos se influyen mutuamente, por lo que la existencia de disfunción sexual femenina (DSF) puede influir en el tratamiento del hombre que busca ayuda clínica. Identificar la disfunción sexual en las parejas femeninas de los pacientes que asisten a una Clínica de Andrología puede brindar una oportunidad terapéutica. Los autores pretenden evaluar la proporción de DSF en esta población comparándola con un grupo de control. Material y métodos: Estudio longitudinal durante 12 meses. Las parejas femeninas de los pacientes que asistieron a la Clínica de Andrología y que participaron en el estudio (grupo de estudio) completaron el Índice de Función Sexual Femenina, de la misma forma que las mujeres, que sirvieron como control (grupo de control). También se recopilaron datos adicionales como edad, duración, calidad de la relación y las relaciones entre los anteriores. Resultados: De las 30 mujeres incluidas en el grupo de estudio, 14 (46,6%) consideraron que su vida sexual actual era peor que en relaciones anteriores. De las 20 mujeres del grupo control, el 60% consideró que su vida sexual actual era mejor. En el grupo de estudio, 22 (73,3%) tenían DSF, con una puntuación media de Índice de Función Sexual Femenina de 20,5, mientras que solo 3 mujeres en el grupo control (15%) tenían DSF, con una puntuación media de 30,7 (p <0,01). Conclusiones: Nuestro estudio demostró que la proporción de DSF en parejas femeninas de pacientes que acuden a una Clínica de Andrología es significativamente mayor que en el grupo control. El tratamiento de la disfunción sexual femenina debe considerarse como una oportunidad terapéutica para la pareja en este escenario. (AU)

RESUMO

The purpose of this article is to provide an explanation of the background behind a checklist that declares the laboratory methods used in a scientific study. It focuses primarily on implementing laboratory procedures to yield reliable results in basic semen examinations. While the World Health Organization (WHO) and international standards provide recommendations for basic semen examination, manuscripts submitted to Andrology frequently lack transparency regarding the specific techniques used. In addition, the terminology used for semen examination results often fails to provide a clear definition of the groups under study. Furthermore, the WHO's reference limits are often misinterpreted as strict boundaries between fertility and infertility. It is important to note that valid clinical andrological diagnoses and treatments cannot rely solely on semen examination results; they require proper laboratory procedures as a foundation for diagnosing and treating male patients. Therefore, scientific journals should promote the adoption of robust laboratory practices and an accurate definition of patient groups. A checklist can facilitate the design of high-quality studies and the creation of informative publications. Further, it can help journals assess submitted manuscripts and improve the overall quality of their publications.

RESUMO

Patient Health Questionnaire-9 (PHQ-9) is the most widely used tool for screening for major depressive disorder (MDD). Although its reliability and validity have been proven, missed or misjudged cases during MDD screening are often encountered. A nomogram that considers the weights of depressive symptoms was developed using data from premature ejaculation patients to improve screening accuracy. During a 33-month prospective study, a training cohort comprising 605 participants from Xijing Hospital was used to develop and internally validate the nomogram. A validation cohort comprising 461 patients from Xi'an Daxing Hospital was also used to externally test the nomogram. The nomogram was established by integrating the LASSO regression-based optimal predictors of MDD according to their coefficients in a multivariate logistic regression model. The nomogram was well-calibrated during internal and external validations. Moreover, it showed a better discriminatory capacity and yielded more net benefits in both validations than PHQ-9. With better performance, the nomogram may help reduce the number of missed or misjudged cases during MDD screening. This study is the first to weigh the direct indicators of MDD under the DSM-5 criteria, presenting a fresh concept that can be applied to other populations to enhance screening accuracy.

RESUMO

The andrological study of a species involves the macro- and microscopic analyses of the internal reproductive organs and the evaluation of seminal parameters and ultrastructural characteristics of the spermatozoa. As in other vertebrates, the male reproductive tract in chondrichthyans consists of testes and reproductive ducts (efferent duct, epididymis, Leydig's gland, ductus deferens and seminal vesicle). In this study the authors used three adult specimens of Zapteryx brevirostris from wild capture kept at the Ubatuba Aquarium, Brazil. Semen was collected by abdominal massage over the location of the seminal vesicle, preceded by ultrasonographic evaluation. The semen collected was diluted 1:200 and subject to quantitative and morphological analyses. Ultrastructural analysis was performed using transmission and scanning electron microscopy. Correlation was observed between successful collection and ultrasonographic image of an engorged seminal vesicle, as well as testicles with easily delimitable margins and higher echogenicity. It was possible to identify free spermatozoa with helical filiform appearance, as well as spermatozeugmata. The average sperm concentration resulted in 5 million packets per millilitre and 140 million spermatozoa per millilitre. The sperm nucleus is described as follows: cone shaped, parachromatin sheath less dense than the chromatin of the nucleus, smooth depression of the nuclear fossa, abaxial axoneme 9 + 2 and accessory axonemal columns in positions 3 and 8 and oval shaped, with flattened inner surface in cross-section. These results broaden the knowledge of the andrology of this species, contributing to ex situ breeding programmes.

RESUMO

The 14th Network of Young Researchers in Andrology (NYRA) meeting was a 2-day conference held at the University of East Anglia in Norwich, UK, organized by the NYRA. The meeting brought together researchers and experts to discuss and exchange ideas on male infertility and spermatogenesis. The meeting covered a wide range of topics related to male germline research, including the impact of mutations in the male germline on future generations, the use of innovative sequencing tools for the study of male infertility, and the intricate germline epigenome. The impact of aging on spermatogenesis was also discussed, with a focus on the increased DNA fragmentation rates, changes in DNA methylation patterns, and longer telomeres associated with aging sperm. Additionally, progress on fertility preservation options for children undergoing gonadotoxic cancer treatments was presented. The meeting also featured workshops on leadership and career development strategies in science, providing a valuable opportunity for young researchers to learn from experts in the field and exchange ideas with their peers. Overall, the meeting provided a platform for researchers to discuss the latest developments in male germline research, highlighting the importance of empowering young researchers to tackle male reproductive health.

RESUMO

BACKGROUND: Telemedicine gained wide acceptance during the COVID-19 pandemic, as it was deemed critical for patient care when lockdowns were implemented worldwide. While there is evidence to suggest that urology patients were receptive to telemedicine, no systematic review has been done to date on andrology patients and their perception of telemedicine. METHODS: Three electronic databases, PubMed, Scopus, and Web of Science, were searched from their inception until June 2022 for relevant articles. Two independent teams reviewed abstracts and extracted data from the selected manuscripts. A meta-analysis was completed in line with PRISMA 2020 and AMSTAR Guidelines. For our study, we limited telemedicine to communication through videoconferencing or telephone encounters between patients and medical professionals. Positive response to telemedicine was defined as patients "wishing for telemedicine consultation", "preferring telemedicine over in person", "accepting the current telemedicine arrangement", "having needs addressed with teleconsultation", or "willingness to do a teleconsultation". RESULTS: Of the 1128 retrieved abstracts, 56 underwent full-text review and 12 were included in the final analysis, comprising a total cohort of >4021 cases. Video visits were evaluated in 5 studies, telephone encounters were analyzed in 2 studies, and both methods were examined in 1 randomized control study. Three studies showed that andrology and sexual medicine are compatible with telemedicine, with few 30- and 90-day in-person revisit rates. Telemedicine was shown to save an average cost of US$149-$252 per patient, and 8 studies that directly assessed andrology patient perceptions of telemedicine showed that most patients had a "positive perception."Pooled analyses of the positive responses to telemedicine were 68.7% (95% CI, 49.4%-83.1%, P = 0.057), and those of patients who recommended telemedicine were 65.1% (95% CI, 18.4%-93.9%, P = 0.577). While the percentage of patients recommending telemedicine was high among studies using videoconferencing, the percentage dropped in studies using telephone visits only. The difference between recommending video and telephone practices was statistically significant, with 84.6% pooled proportion for recommending video practice compared to 38.9% pooled proportion for recommending telephone practice, P = 0.035. In the telephone-only encounters, up to 27.1% of patients preferred in-person visits, as security and privacy of any mode of telecommunication were of concern. CONCLUSIONS: Most patients have a positive perception of telemedicine, particularly with videoconferencing and less so with telephone visits. These results suggest that telemedicine will likely continue to play a pivotal role in andrology and sexual medicine practices.

RESUMO

Abnormal body mass index (BMI) is associated with an increased risk of erectile dysfunction (ED). However, the relationship between different BMI categories and the levels of ED severity remains unclear. In the current study, 878 men from the andrology clinic in Central China were recruited. Erectile function was assessed by the International Index of Erectile Function (IIEF) scores. Questionnaires included questions about demographic characteristics (age, height, weight, educational status), lifestyle habits (drinking, smoking, sleep time), and medical history. Logistic regression was used to examine the association between ED risk and BMI. The incidence of ED was 53.1%. BMI was significantly higher in men from the ED group than in those from the non-ED group (P = 0.01). Compared with the normal weight group, obese men had a higher risk of ED (OR = 1.97, 95% CI = 1.25-3.14, P = 0.004), even after adjustment for potential confounders (OR = 1.78, 95% CI = 1.10-2.90, P = 0.02). Moreover, the positive correlation between obesity and moderate/severe ED severity was confirmed by logistic regression analysis (moderate/severe ED, OR = 2.71, 95% CI = 1.44-5.04, P = 0.002), even after adjusting for potential confounders (OR = 2.51 95% CI = 1.24-5.09, P = 0.01). Collectively, our findings indicate a positive correlation between obesity and the risk of moderate/severe ED. Clinicians could pay more attention to moderate/severe ED patients to maintain a healthy body weight to improve erectile function.
