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

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

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

The management of young patients with cancer presents several unique challenges. In general, these patients are ill prepared for the diagnosis and the impact on their fertility. With the improved survival for all tumour types and stages, the need for adequate fertility counselling and a multidisciplinary approach in the reproductive care of these patients is paramount. Recent advances in cryopreservation techniques allow for the banking of spermatozoa, oocytes, embryos and ovarian tissue without compromising survival. This Canadian Fertility and Andrology Society (CFAS) guideline outlines the current understanding of social and medical issues associated with oncofertility, and the medical and surgical technologies available to optimize future fertility.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: The number of studies in the field of andrology is increasing day by day, but a bibliometric study covering the entire literature on andrology has not yet been conducted. This bibliometric study aims to shed light on the question of where we came from and where we are going in andrology from past to present. It also aimed to summarize the intellectual structure of andrology to reveal global productivity and identify and map the latest trends of scientific articles published in the field of andrology. MATERIALS AND METHODS: 16,659 articles published between 1980 and 2022 were extracted from the Web of Science and analyzed using various statistical methods. Bibliometric network visualization maps revealed trending topics, global productivity, the most influential studies, and international collaborations. Spearman's correlation analysis was used for determining correlations. RESULTS: The top three productive countries were United States of America (3,452; 20.7%), China (2,300; 13.8%), and Germany (1,069; 6.4%). The top two most productive authors were Agarwal A. (n=130) and Nieschlag E. (n=130). The most productive institution was the Egyptian Knowledge Bank (n=422). From past to present, the most studied subjects were testis, male infertility, spermatozoa, testosterone, infertility, erectile dysfunction, spermatogenesis, sperm, prostate cancer (PCA)/neoplasms, oxidative stress, fertility/fertilization, semen, rat(s), apoptosis, azoospermia, sperm motility, human and varicocele. CONCLUSIONS: The trend topics that have been researched more in recent years include erectile dysfunction, oxidative stress, prostate cancer, sperm quality, sperm parameters, infertility, premature ejaculation, diabetes mellitus, obesity, prognosis, sperm DNA fragmentation/damage, antioxidant, asthenozoospermia, varicocelectomy, COVID-19, inflammation, prostatectomy, metabolic syndrome, hypogonadism, benign prostatic hyperplasia, lower urinary tract symptoms, meta-analysis, sexual dysfunction, peyronie's disease, and proliferation. We identified the research leadership of China, Japan, Turkey and India, in addition to Western countries, such as the USA and European countries.

RESUMEN

Introducción: Durante años, el varicocele se ha propugnado como la causa más común de infertilidad, siendo esta patología la de mayor incidencia en los varones como factor causal (19 - 41%). Material y Métodos: Se evaluaron 228 pacientes, sexo masculino (18 y 39 años) con subfertilidad primaria con o sin varicocele. Se realizó historia clínica, examen físico, laboratorio y espermograma por duplicado. Se dividieron un grupo de 120 pacientes con subfertilidad primaria, varicocele izquierdo y por lo menos un parámetro seminal alterado en dos muestras sometidos a varicocelectomía y control seminal 6 y 9 meses post-operatorio y otro grupo 108 pacientes de iguales características pero sin varicocele. Se utilizaron criterios OMS en concentración, motilidad y morfología espermática. Estudio de casos y controles. Resultados: La mejoría en la concentración de espermatozoides tras el tratamiento quirúrgico fue de 20,06% (p‹ 0,0001) a los 6 meses y 26,31% (p‹ 0,0001) a los 9 meses. La motilidad aumentó 21,32% (p‹ 0,001) a los 6 meses y 28,28% (p‹ 0,0001) a los 9 meses y la morfología mejoró un 26,8% (p‹ 0,0001) a los 6 meses y 57,38% (p‹ 0,0001) a los 9 meses. Todas las variables resultaron estadísticamente significativas tras el tratamiento quirúrgico. No hubo diferencia estadísticamente significativa en ninguna de las variables entre el grupo pre-quirúrgico y el grupo control, y si las hubo en todas las variables estudiadas entre el grupo control comparado con el post- quirúrgico, a favor de este último. Los porcentajes de mejoras entre el grupo post-quirúrgico a los 6 meses y 9 meses de la cirugía, a favor de este último fueron 7,5% (p‹ 0,0001) en la concentración, 5,28 % (p‹ 0.0001) en la motilidad y 25,32% (p‹ 0.0001) en la morfología... Conclusiones: Los parámetros seminales evidenciaron cambios positivos luego de la varicocelectomia y más aún con el transcurrir del tiempo.


Introduction: Varicocele has been proposed for years as the most common cause of infertility, and this condition is the prevalent incidence as causal factor. (19-41%) Material and methods: 228 male patients (between 18 and 39 years old) were evaluated with primary sub fertility with or without varicocele. The records included history, physical examination and two spermogram for patient. The population was divided in two groups. The first one of 120 patients with primary subfertility, left varicocele and at least one abnormal seminal parameter in two samples, with surgical resection of varicocele and final seminal post-surgical evaluation at 6 and 9 months. The other group included 108 patients with similar characteristics but without varicocele. The WHO criteria for spermatic concentration, motility and morphology were applied. Evaluation of cases and controls. Results: The improvement in spermatozoa concentration after treatment was of 20.06% (p<0,0001). The motility improved 21,32% at 6 months (p<0,0001) and 28,28% at 9 months (p<0,0001).The morphology improved 26,8% at 6 months (p<0,0001) and 57,38% at 9 months (p<0,0001)All the parameters were statistically significant after surgery. While there were no significant differences in any parameter between the pre-surgical group and the control group, there were differences in all the parameters evaluated between the control group and the post-surgical group, with best results in the latter.The percentages of improvement in the post-surgical group were 7,5%(p < 0,0001) in concentration, 5,28% in motility and 25,32% in morphology...Conclusions: The seminal parameters showed positive changes after varicocelectomy, especially over time.

RESUMEN

ABSTRACT This study describes a new method of microcentrifugation as an improved, viable, cost-effective option to the classical Cytospin apparatus to confirm azoospermia. Azoospermic semen samples were evaluated for cryptozoospermia by a centrifugation method similar to that of World Health Organization guidelines (2010; entire specimen centrifuged at 3000g for 15 min, and aliquots of the pellet examined). Then, if no sperm were detected, the pellet from that procedure was resuspended in culture medium, centrifuged (2000g for 15 min), and the entire pellet spread on a 4 X 6mm area of a slide and stained using the Christmas tree method (Nuclear-Fast solution and picric acid). The entire stained area was examined for the presence or absence of sperm. A total of 148 azoospermic samples (after standard WHO diagnosis) were included in the study and 21 samples (14.2%) were identified as sperm-positive. In all microcentrifugation slides, intact spermatozoa could be easily visualized against a clear background, with no cellular debris. This novel microcentrifugation technique is clearly a simple and effective method, with lower cost, increasing both sensitivity and specificity in confirming the absence or presence of spermatozoa in the ejaculate. It may represent a step forward of prognostic value to be introduced by andrology laboratories in the routine evaluation of patients with azoospermia in the initial semen analysis.

RESUMEN

A sexualidade como função fisiológica e o desejo sexual como necessidade orgânica primária. A educação sexual – para homens e mulheres – como estratégia para solucionar não só o problema das doenças venéreas, mas outros como a desarmonia conjugal e as perversões sexuais. A legitimação e institucionalização da andrologia, a ciência do homem. A crítica à abstinência sexual socialmente imposta às mulheres solteiras e viúvas. Essas eram algumas das ideias defendidas pelo autoproclamado sexólogo e andrologista brasileiro José de Albuquerque, médico que, embora tenha enfrentado tabus, levantado polêmicas e causado rebuliço na elite carioca nos anos 1930, ficou esquecido ao longo das décadas seguintes. Mas agora esse importante personagem da história da sexualidade no Brasil volta à cena com a publicação de sua autobiografia até então inédita. Enfim, para além das peripécias de uma vida bastante agitada e de uma singular trajetória profissional, a autobiografia desvela aspectos interessantíssimos do desenvolvimento das ciências médicas no Rio de Janeiro do entreguerras. Nela, aparecem seus principais personagens, a vida em suas escolas e o universo de sua prática, afirmam os organizadores. Sua leitura na segunda década dos anos 2000 permite colocar em uma nova perspectiva a própria história da sexualidade no Brasil, um campo que hoje, como nos anos 1930, continua tensionado por inúmeros dilemas, conflitos e impasses.

RESUMEN

Bull breeding soundness evaluation (BBSE) is a method applied to reduce the risk of using subfertile bulls in herds. There are currently two BBSE systems, those of the Society for Theriogenology (SFT) and the Western Canadian Association of Bovine Practitioners (WCABP). Scrotal circumference (SC), sperm motility (SM) and normal sperm (NS) of 454 bulls aged between 12 and 15 months of a Spanish beef breed were used to compare both systems, and since there is no agreement on that BBSE system must be applied in Spain, a single one was proposed for its consideration. SC was adjusted to 15 months (SC15) and the mean of the BBSE traits was: SC15 (34.2±2.4cm), SM (76.6±14.6%) and NS (76.8±12.3%). In the PROPOSED system, the SM and NS thresholds were those defined by the WCABP system, while the SC15 thresholds were set by combining the SFT threshold and SC15±1SD in order to establish four classification categories, the three proposed by the WCABP system: unsatisfactory, questionable and satisfactory, and other category, called superior, for bulls with SM≥60%, NS≥70% and SC15≥Mean+1SD. The PROPOSED system scored fewer bulls as unsatisfactory than the SFT and the WCABP systems (8.6%, 23.6% and 22.5%, respectively; P<0.01), while the percentage of bulls from worst to best in the other three categories under the PROPOSED system was: 26.0%, 54.2% and 11.2%, respectively. In conclusion, the PROPOSED system gives more emphasis to SC, sets differences between bulls classified as satisfactory by the other systems and can be considered a good system for Spain and for other countries that have no defined their own system...
