RESUMO

BACKGROUND: Digital health has surged during the Covid health crisis, and the use of social media, already prevalent in medicine, has significantly increased. There are Social Networks groups dedicated to physicians with an educational purpose. These groups also facilitate peer discussions on medical questions and the sharing of training materials. OBJECTIVES: The aim of our study was to assess the value of these new tools and their contribution to medical education. METHODS: An anonymous questionnaire was conducted among members of a Social Networks community group for physicians. The survey received responses from 1451 participants. RESULTS: The majority of participants believed they had enriched their medical knowledge and accessed documents they would not have accessed without the group. Subgroup analysis showed that the contribution of this tool is more pronounced for general practitioners and doctors practicing in limited healthcare access. CONCLUSION: It is essential to develop digital tools that enhance physician training, and social networks represent a valuable educational tool.

RESUMO

PURPOSE: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls. This study aimed to evaluate the effect of VR on conventional semen parameters in infertile patients with clinical varicocele compared to untreated controls. MATERIALS AND METHODS: A literature search was performed using Scopus, PubMed, Embase, and Cochrane databases following the Population Intervention Comparison Outcome (PICOS) model (Population: infertile patients with clinical varicocele; Intervention: VR [any technique]; Comparison: infertile patients with clinical varicocele that were untreated; Outcome: sperm concentration, sperm total count, progressive sperm motility, total sperm motility, sperm morphology, and semen volume; Study type: randomized controlled trials and observational studies). RESULTS: A total of 1,632 abstracts were initially assessed for eligibility. Sixteen studies were finally included with a total of 2,420 infertile men with clinical varicocele (1,424 patients treated with VR vs. 996 untreated controls). The analysis showed significantly improved post-operative semen parameters in patients compared to controls with regards to sperm concentration (standardized mean difference [SMD] 1.739; 95% CI 1.129 to 2.349; p<0.001; I²=97.6%), total sperm count (SMD 1.894; 95% CI 0.566 to 3.222; p<0.05; I²=97.8%), progressive sperm motility (SMD 3.301; 95% CI 2.164 to 4.437; p<0.01; I²=98.5%), total sperm motility (SMD 0.887; 95% CI 0.036 to 1.738; p=0.04; I²=97.3%) and normal sperm morphology (SMD 1.673; 95% CI 0.876 to 2.470; p<0.05; I²=98.5%). All the outcomes showed a high inter-study heterogeneity, but the sensitivity analysis showed that no study was sensitive enough to change these results. Publication bias was present only in the analysis of the sperm concentration and progressive motility. No significant difference was found for the semen volume (SMD 0.313; 95% CI -0.242 to 0.868; I²=89.7%). CONCLUSIONS: This study provides a high level of evidence in favor of a positive effect of VR to improve conventional semen parameters in infertile men with clinical varicocele. To the best of our knowledge, this is the first SRMA to compare changes in conventional semen parameters after VR with changes in parameters of a control group over the same period. This is in contrast to other SRMAs which have compared semen parameters before and after VR, without reference to a control group. Our findings strengthen the available evidence and have a potential to upgrade professional societies' practice recommendations favoring VR to improve conventional semen parameters in infertile men.

RESUMO

Background: Human sperm chromatin condensation is a sum of epigenetic events that allows for the near-complete replacement of histones with protamines. Under high-magnification microscopy, nuclear vacuoles have been described as thumbprints with poor chromatin condensation. The objective of this study is to examine whether vacuolated spermatozoa carry specific epigenetic marks, which may influence embryo development. Methods: The presence and three-dimensional distribution of ten epigenetic marks (protamine-P2, histone-H3, H3K4me1/me2/me3, H3K9me1/me2/me3, H3K27me3, H4k20me2) were evaluated and compared in morphometrically normal spermatozoa according to the presence or absence of a large vacuole occupying more than 15% of the head surface (n = 4193). Results: Vacuolated spermatozoa were significantly more frequently labelled with H3 and H3K4me3 than normal spermatozoa (88.1% ± 2.7 and 78.5% ± 5.2 vs. 74.8% ± 4.8 and 49.1% ± 7.4, respectively; p = 0.009 and p < 0.001) and significantly less marked by P2 and H3K27me3 (50.2% ± 6.2 and 63.9% ± 6.3 vs. 82.1% ± 4.4 and 73.6% ± 5.1, respectively; p < 0.001 and p = 0.028). In three dimensions, vacuoles are nuclear concavities filled with DNA carrying the H3K4me3 marker. Conclusion: High-magnification microscopy is a simple tool to estimate in real time the sperm epigenetic profile. The selection of normal spermatozoa without vacuoles and the deselection of spermatozoa with vacuoles appear to be epigenetically favorable to embryo development and safe offspring.

RESUMO

BACKGROUND: A very small number of studies have indicated that azoospermia or negative testicular sperm extraction (TESE) outcomes are linked to depression or erectile dysfunction. However, the data are often weak, conflicting and gathered with non-validated questionnaires. Hence, we performed a cross-sectional study of 44 men with non-obstructive azoospermia. Levels of self-esteem and the quality of the couple's sex life and overall relationship were assessed with validated questionnaires before and after the TESE procedure as a function of the TESE outcome. RESULTS: A positive TESE outcome (n = 24) was associated with a statistically significant increase in self-esteem (particularly with regard to family aspects), sexual health and couples' adjustment quality. In contrast, a negative TESE outcome (n = 20) was associated with statistically significant decreases in self-esteem, erectile function, intercourse satisfaction, orgasmic function, couples' adjustment quality and all aspects of the couple's relationship (consensus, cohesion, satisfaction and affection). CONCLUSION: For men with non-obstructive azoospermia (NOA), negative TESE outcomes may have a negative impact on self-esteem and the quality of the couple's sex life and overall relationship. This should be borne in mind when counselling men with NOA and their partners to (ideally) help them to cope with and decrease the harmful impacts of azoospermia and negative TESE.


RESUME: INTRODUCTION: Quelques études concernant l'azoospermie ou les résultats négatifs de l'extraction de sperme testiculaire (TESE) montrent que ces résultats peuvent être liés à la dépression ou aux dysfonctions érectiles. Cependant, les données sont souvent faibles, contradictoires et recueillies à l'aide de questionnaires non validés. Nous avons donc réalisé une étude transversale auprès de 44 hommes atteints d'azoospermie non obstructive (ANO). Les niveaux d'estime de soi et la qualité de la vie sexuelle du couple et de la relation globale ont été évalués à l'aide de questionnaires validés avant et après la procédure TESE en fonction du résultat de la TESE. RéSULTATS: Un résultat positif de TESE (n = 24) a été associé à une augmentation statistiquement significative de l'estime de soi (en particulier en ce qui concerne les aspects familiaux), de la santé sexuelle et de la qualité de l'adaptation du couple. En revanche, un résultat négatif de TESE (n = 20) a été associé à une diminution statistiquement significative de l'estime de soi, de la fonction érectile, de la satisfaction des rapports sexuels, de la fonction orgasmique, de la qualité de l'adaptation du couple et de tous les aspects de la relation de couple (consensus, cohésion, satisfaction et affection). CONCLUSION: Chez les hommes atteints d'ANO, une TESE négative peut avoir un impact négatif sur l'estime de soi et la qualité de la vie sexuelle et de la relation globale du couple. Il convient de garder cela à l'esprit lors du conseil aux hommes atteints d'ANO et à leurs partenaires afin de les aider (idéalement) à faire face aux impacts néfastes de l'azoospermie et de la TESE négative et à les réduire.
