Infertile men with nonobstructive azoospermia (NOA) associated with varicocele may benefit from varicocele repair with recovered sperms in semen. Currently, there is no clinically applied method to predict the success of seminal sperm recovery in this subset of azoospermic men. <i>Objective</i>. We aimed to evaluate the predictive role of the seminal testis expressed protein (TEX101) in sperm recovery in the semen of NOA men with palpable bilateral varicocele after microsurgical varicocelectomy. <i>Patients and Methods</i>. This prospective cross-sectional cohort study included 40 patients with NOA and bilateral varicocele. Seminal TEX101 levels were measured followed by subinguinal microsurgical varicocele repair. Two seminal analyses were carried out at 3- and 6-month follow-up periods to evaluate seminal sperm recovery. <i>Results</i>. After varicocele repair, sperms were recovered in the semen of 10/40 patients (25%) along the follow-up periods (seven patients after 3 months and additional three patients after 6 months). The preoperative median seminal TEX101 level was significantly higher in NOA men with seminal sperm recovery compared with NOA patients without seminal sperm recovery (13.5 vs. 9.8 ng/ml, <i>p</i> = 0.014). Besides, the serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) median levels were significantly higher in NOA men without seminal sperm recovery compared with NOA men with seminal sperm recovery (<i>p</i> = 0.001, <i>p</i> = 0.01). There were nonsignificant differences comparing the preoperative testicular volume or serum testosterone levels between the two investigated groups (<i>p</i> = 0.072, <i>p</i> = 0.272). A cutoff value of 9.9 ng/ml was demonstrated to have preoperative TEX101 prediction of seminal sperm recovery (sensitivity of 90% and specificity of 57%). <i>Conclusion</i>. Preoperative seminal TEX101 could be considered as a biomarker for sperm recovery for seminal sperm recovery in NOA cases associated with varicocele after its surgical repair. Further work at this point with larger number of cases should be carried out to verify its potential importance.</p>\u0000 </div>","PeriodicalId":7817,"journal":{"name":"Andrologia","volume":"2023 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2023/5652572","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136017132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although immunotherapy has been applied in clinic, the response rate is not high, and also there is a lack of effective biomarkers. In this study, through high-throughput transcriptome sequencing and public data mining, the expression of hepatitis A virus cellular receptor 2 (HAVCR2) was found to be significantly upregulated in TGCT tissue and correlated with poor prognosis. Additionally, the expression level of HAVCR2 was negatively correlated with its DNA methylation but positively correlated with its copy number level. The HAVCR2 expression level was significantly positively correlated with the infiltration of six types of immune cells, including B cells, CD4+ T cells, CD8+ T cells, neutrophils, macrophages, and myeloid dendritic cells. Also, the higher its expression level, the higher the immune cell abundance. Tumor immune dysfunction and exclusion (TIDE) scoring analysis showed that HAVCR2 was related to the responsiveness to TGCT immunotherapy.

Acrylamide is a poisonous chemical produced under the oxidative stress as a result of intracellular reactive oxygen species formation and toxicity. Heating carbohydrates-rich meals give acrylamide that is widely used in the industry. The precise mechanism of acrylamide toxicity is unknown. The current study aimed to examine the impacts of Taify pomegranate juice (TPJ) from Taif area (<i>Punica granatum L</i>.) on acrylamide-induced testicular stress and dysfunction. Twenty four male of adult Wistar rats, were divided into four groups: Group 1 was a negative-control received only saline; Group 2 was a positive-control that received orally acrylamide (20 mg/kg/bw) for consecutive 4 weeks; and Group 3 received TPJ; 2 mL/kg/bw, orally for 4 weeks. Rats in Group 4 received pomegranate juice and acrylamide as described in Groups 2 and 3, with the TPJ delivered 1 week before the acrylamide. Acrylamide elevated serum levels of inflammatory cytokines (interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-<i>α</i>)). Moreover, acrylamide decreased concentrations of follicle stimulating hormone (FSH), leutinizing hormone (LH), and testosterone and altered semen characteristics (decreased sperm viability and concentration, and increased sperm abnormalities). Acrylamide increased malondialdehyde levels (MDA), while it decreased antioxidant activities (superoxide dismutase; SOD and reduced glutathione; GSH). The inflammation associated cytokines were restored by TPJ administration to acrylamide rats. GSH and SOD were significantly recovered to near control levels in TPJ plus acrylamide group compared to acrylamide-administered rats. TPJ preadministration to rats restored semen profiles, alteration in testis pathology, and normalized the changes on the male reproductive hormones affected by acrylamide. Furthermore, the TPJ reversed the upregulation in caspases-3 and the decrease in B-cell lymphoma-2 (Bcl-2) gene expressions affected by acrylamide, with significant upregulation of hemoxygenase-1 (HO-1) and nuclear factor erythroid-2 (Nrf2) mRNA expression.

The recent emergence of next-generation sequencing offers an opportunity to analyze many genes and their interactions at once, and whole-exome sequencing (WES) together with whole-genome sequencing (WGS) was recently suggested for implementation of diagnosis workup in severe infertility cases. However, the reports on WES in conjunction with burden tests and gene network analysis are scarce or lacking in cases of severe male infertility.

Histopathological evaluation was performed using the Johnsen and Cosentino scores for seminiferous tubules. Malondialdehyde, superoxide dismutase, and total glutathione levels were determined in testicular tissues. Moreover, Nrf2, heme oxygenase 1 (HO-1), NAD(P)H quinone dehydrogenase 1 (NQO1), nuclear factor kappa B (NF-<i>κ</i>B), and inflammatory cytokine (interleukin 1b (IL1b), IL6, and tumor necrosis factor alpha (TNF-<i>α</i>)) levels were determined through quantitative polymerase chain reaction. Nuclear Nrf2 and cytoplasmic HO-1 and NQO1 protein levels were also evaluated. DMF significantly improved the testis-to-body weight ratio and reduced histopathological damage in the testes. Moreover, it significantly improved the concentration of malondialdehyde, superoxide dismutase, and total glutathione. Furthermore, it inhibited NF-<i>κ</i>B and inflammatory cytokine mRNA expression compared with the findings obtained in untreated rats with IRI (all <i>p</i> &lt; 0.05). Nrf2, HO-1, and NQO1 expressions (mRNA and protein) were markedly elevated following DMF treatment in rats with IRI (all <i>p</i> &lt; 0.05). DMF administration activated the Nrf2 signaling pathway and induced antioxidant and anti-inflammatory effects, thereby improving IRI-induced testicular damage. Thus, DMF may prevent IRI following testicular torsion.</p>\u0000 </div>","PeriodicalId":7817,"journal":{"name":"Andrologia","volume":"2023 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2023/7086044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42792938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
