PurposeYoung adult Latino testicular cancer survivors experience adverse impacts after treatment. We developed Goal-focused Emotion regulation Therapy (GET) to improve distress symptoms, goal navigation skills, and emotion regulation. This open pilot trial extended GET to Latino young adult survivors of testicular cancer and assessed feasibility and tolerability as well as changes in anxiety and depressive symptoms. Secondary outcomes included goal navigation, emotion regulation, and components of hope-related goal processes (i.e., agency and pathway mapping). To assess the extent to which GET is culturally congruent or in need of adaptation, the influence of simpatía and acculturative stress were also examined.MethodsThirty-five eligible young adult (age 18-39) survivors treated with chemotherapy were enrolled and assessed at baseline. Study acceptability, tolerability, and therapeutic alliance were examined. Preliminary efficacy was evaluated for changes in anxiety and depressive symptoms as well as psychological processes (goal navigation, agency, goal pathway skill, and emotion regulation) from baseline to immediate post- and 3-month post-intervention.ResultsAmong the 35 men assessed at baseline, 54% initiated intervention sessions. Among these, 94.7% completed all study procedures. Helpfulness ratings of intervention components and therapeutic alliance scores were strong. Repeated measures ANOVA revealed significant reductions in anxiety and depressive symptoms from pre- to post-intervention with sustained change at the 3-month follow-up. Favorable patterns of change were also observed in GET-related psychological processes. Simpatía was associated with less depressive symptoms at post-intervention, but not change in anxiety. Acculturative stress was associated with increased anxiety and depressive symptoms over time.ConclusionGET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adult Latino men. Results should be considered preliminary but suggest meaningful changes in emotional and psychological outcomes.

The genetic landscape of urologic cancers has evolved with the identification of actionable mutations that impact diagnosis, prognosis, and therapeutic strategies. This narrative review consolidates existing literature on genetic mutations across key urologic cancers, including bladder, renal, prostate, upper tract urothelial, testicular, and penile. The review highlights mutations in DNA damage repair genes, such as BRCA1/2 and PTEN, as well as pathway alterations like FGFR and PD-L1 overexpression. These mutations influence tumor behavior and therapeutic outcomes, emphasizing the need for precision oncology approaches. Molecular profiling, through tools like next-generation sequencing, has revolutionized patient care by enabling targeted treatment strategies, especially in cancers with distinct molecular subtypes such as luminal or basal bladder cancer and clear cell renal carcinoma. Emerging therapies, including FGFR inhibitors and immune checkpoint blockade, offer new treatment avenues, although resistance mechanisms remain a challenge. We also emphasize the importance of biomarker identification for personalized management, especially in metastatic settings where treatment intensification is often required. Future research is needed to further elucidate our understanding of the genetics affecting urologic cancers, which will help develop novel, individualized therapies to enhance oncologic outcomes.

Objective Materials and Methods Results Discussion To conduct a systematic review of the current literature to determine the current role of primary retroperitoneal lymph node dissection (RPLND) in stage II testicular seminoma and its associated oncological, functional and peri‐operative outcomes.A comprehensive literature search was conducted in Medline, Embase, and Scopus for publications from inception until November 2023. The systematic review was registered on PROSPERO (ID CRD42023449781), was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and utilised the Methodological Index for Non‐Randomised Studies (MINORS) tool.Six studies involving 385 patients were analysed, with 48.5% clinical stage IIA and 51.5% stage IIB seminomas. The patients’ mean (range) age was 37 (20–64) years. The median operation time was 187 min, median estimated blood loss was 150 mL and median length of hospital stay was 4 days. In all, 6.1% of patients developed complications that were greater or equal to Clavien–Dindo grade 3. Only four studies reported on anejaculation rate (median: 4.9%). Only one study had long‐term data, demonstrating a 92% 5‐year overall survival for stage IIA/B disease treated with RPLND. The remaining five studies had a median follow‐up of between 18.5 and 37 months and reported a mean recurrence rate of 15.6%. Most recurrences (78%) were not within the field of RPLND. Recurrence was associated with higher clinical and pathological lymph node stage, and metachronous or delayed development of retroperitoneal lymphadenopathy (initially stage I disease, as opposed to de novo stage IIA/B disease).Primary RPLND, performed by experienced surgeons, has good peri‐operative outcomes. Recurrence is more common than with standard treatment, but long‐term survival and functional data are limited, although promising. [ABSTRACT FROM AUTHOR]

Background: Qualitative research has explored how some testicular cancer survivors (TCS) experience the psychological impacts of diagnosis and treatment. More research into the impacts of testicular cancer (TC) on adolescent and young adults (AYA) is needed due to the critical period of identity development. The present study aimed to explore how AYA with TC appraise and make sense of their experience and to develop a greater understanding of psychosexual identity development in AYA TCS. Method: Eight AYA TCS were interviewed. The results were analysed using Interpretative Phenomenological Analysis. The questions explored the experiences relating to diagnosis and treatment, how it affected their psychosexual identity development (e.g., sexual relationships and self-image) and the meanings attached to the experiences. Analysis: Four Group Experiential Themes were developed from the data; 'Dealing with the shock', 'Fear and weight of responsibility', 'those closest to me' and 'sense of change'. Discussion: The AYA TCS experiences may result in adoption of traditional masculine traits (e.g., stoicism) or abandonment of traditionally masculine traits (E.g. violence and aggression). AYA TCS also described feelings of insecurity when compared to other men. Psychology input could help manage stoicism and feelings of inferiority when compared to men with two testicles. Plain language summary: Background: Qualitative research has explored how some testicular cancer survivors (TCS) cope with the psychological impacts of diagnosis and treatment. However, there is a need for more research on the effects of testicular cancer (TC) specifically in adolescent and young adults (AYA), given the critical period of identity development during this stage. The present study aimed to explore how AYA with TC perceive and make sense of their experiences, with a focus on psychosexual identity development. Method: Eight AYA TCS were interviewed, and their responses were analyzed using Interpretative Phenomenological Analysis. The interviews covered topics related to diagnosis, treatment, and how these experiences influenced their psychosexual identity (including sexual relationships and self-image). Analysis: Four main themes emerged from the data: "Dealing with the shock": Participants discussed their initial reactions to the diagnosis. "Fear and weight of responsibility": AYA TCS grappled with fear and the burden of managing their health. "Those closest to me": Relationships with family and friends played a significant role in their experiences. "Sense of change": Participants described how their cancer journey impacted their sense of self. Discussion: AYA TCS may either adopt traditional masculine traits (such as stoicism) or abandon them (e.g., violence and aggression). Additionally, they expressed feelings of insecurity when comparing themselves to other men. Psychology support could help manage stoicism and address feelings of inferiority when compared to men with two testicles. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the potential effects of epigallocatechin-gallate (EGCG) against high-fat diet (HFD)-induced memory decline and testicular abnormalities in male Wistar rats using appropriate standard techniques. The findings showed that HFD consumption led to cognitive deterioration, an imbalance in inflammatory cytokines, an increase in the Lee index, and neuronal death. However, in HFD-exposed rats, EGCG treatment reduced corticosterone, leptin, and the Lee index, improved cognitive impairment, regulated inflammatory, autophagic, and apoptotic processes, increased adiponectin levels, raised brain and testes weight, and protected against neuronal atrophy. Thus, EGCG mitigated the adverse effects of HFD-induced non-spatial memory decline and testicular dysfunction, potentially by reducing hypercortisolism, modulating chemo-brain activity, regulating inflammatory, apoptotic, autophagic, and metabolic hormonal status, and preventing neuronal degeneration.

Seminoma is a malignant germ cell tumor that primarily develops in the testis but can occur in other extragonadal areas, most commonly the mediastinum and retroperitoneum. While generally offering a favorable prognosis, seminomas can sometimes clinically present with misleading characteristics resulting in delayed diagnosis. In this article, we report the case of a 31-year-old male diagnosed with grade IIIC intermediate risk testicular seminoma cTxN3M1bSx, who presented initially with a palpable cervical mass. We focus on the use of radiological modalities for an optimized diagnosis by coordinating our imaging with pathological findings and clinical presentation.

Manual detorsion is infrequently performed in pediatric emergency medicine, particularly in centers with urology coverage. In no other emergency condition does an emergency physician not take immediate action to alleviate pain and damage, even if definitive care is close by. A small number of case reports exist in which pediatric emergency physicians have performed manual detorsion. This review the literature presents the case for routine manual detorsion prior to definitive orchiopexy. [ABSTRACT FROM AUTHOR]

Ruminants are one of the world's economically important species, and their reproductive health is critical to the economic development of the livestock industry. In recent years, research on the relationship between microbiota and reproductive health has received much attention. Microbiota disruption affects the developmental health of the testes and epididymis, the male reproductive organs of the host, which in turn is related to sperm quality. Maintaining a stable microbiota protects the host from pathogens and increases breeding performance, which in turn promotes the economic development of animal husbandry. In addition, the effects and mechanisms of microbiota on reproduction were further explored. These findings support new approaches to improving and managing reproductive health in ruminants through the microbiota and facilitate further systematic exploration of microbiota‐mediated reproductive impacts.

Background: The Background: We evaluate the effects of radiofrequency electromagnetic field (RF-EMF) on rat brain and testicular tissue using histopathology, comet assay, and real-time quantitative PCR techniques. Materials and Methods: Two equal groups of fourteen rats one for sham-control and the other for exposure (n = seven) were created. For a duration of 14 days, the exposure group (2100 MHz, testicular tissue SAR values of 163 mW/kg for 10 g, brain tissue SAR values of 292 mW/kg on average) was subjected to five hours of exposure per day. Evaluations were conducted on tissue gene expression levels, histopathology, and DNA damage to brain tissue. Results: The histological examination of brain tissue from the exposed group revealed vascular alterations and significant edema (p < 0.05). It was determined that RF radiation-induced much more cellular damage in the exposed group (18.26% tail DNA) than in the control group (4.06% tail DNA). Signs of deterioration in spermatogenic cells in the testicular tissue of the exposed group also changed significantly (p < 0.05). The Bax and bcl-2 genes showed a significant difference (p < 0.05) in the mRNA level data, whereas the p53 genes showed no significant change (p > 0.05). Conclusion: These findings suggest that it may cause some histopathological and cellular damage in brain and testis tissue. [ABSTRACT FROM AUTHOR]

Testicular tumors (TTs) are rare in children, posing diagnostic and therapeutic challenges. This retrospective study evaluates the diagnostic and prognostic utility of SALL4 and OCT3/4 in pediatric TTs. We analyzed 18 cases of different types of TTs using immunohistochemistry (IHC) to assess SALL4 (Spalt-like transcription factor 4) and OCT3/4 (Octamer binding transcription factor 3/4) expression. SALL4 was positive in 83.3% of tumors, while OCT3/4 was positive in 38.9% of tumors, with a significantly higher prevalence in patients aged 12–18 years compared to those aged 0–11 years (p = 0.013). Mixed germinal cell tumors were significantly more frequently associated with OCT3/4 (p = 0.003), and a high immunostaining expression for SALL4 was observed primarily in yolk sac tumors and embryonal carcinoma. Our findings suggest that SALL4 and OCT3/4 immunostaining can aid in accurate diagnosis and treatment planning, and underscores the importance of OCT3/4 as a predictive factor in pediatric testicular tumors, highlighting its substantial correlation with tumor type and its impact on treatment response. These markers may guide personalized therapeutic strategies, potentially improving patient outcomes. [ABSTRACT FROM AUTHOR]

Soybean and bee drone milk are promising functional food candidates due to their bioactive compounds and health benefits. This study evaluated fortified soymilk with drone milk (BSDM) in mitigating cisplatin-induced testicular toxicity and explored the mechanisms involved. Different BSDM concentrations were analyzed for physicochemical properties, antioxidant capacity, and sensory attributes. Male Wistar rats were divided into control, BSDM, cisplatin, and cisplatin + BSDM groups. Sperm motility, hormone levels, oxidative stress markers, apoptosis, and inflammation were assessed. BSDM supplementation enhanced phenolic levels, antioxidant potential, nutritional characteristics, and consumer acceptance of soymilk. Rats treated with cisplatin showed reduced testes weight, sperm parameters, hormone levels, and testicular glutathione, along with increased malondialdehyde, total nitrite, NF-κB, caspase-3,and TNF-α expression. BSDM administration mitigated testicular toxicity, restored function, and repaired histological abnormalities by regulating oxidative stress, apoptosis, and inflammation. These findings suggest BSDM as a functional food for alleviating cisplatin-induced testicular toxicity.

ABSTRACT: Egg production performance is an important economic trait in the poultry industry. In previous studies, attention has often been paid to the growth and development of the ovaries, while there has been less research on the testicular tissue of male goose. Due to various factors, there are usually significant differences in the process of testicular spermatogenesis among different goose breeds. The Jilin white goose (JL) is a high-production local goose species in China, domesticated from Anser cygnoides, which has a high egg-laying performance and the egg-laying period can last from February to July. In the production of goose within Jilin Province, the female goose of Jilin White goose is considered as an important maternal parent of synthetic lines, and ganders from Hungarian white goose (HU), Wanxi white goose (WX) and Jilin white goose are the main male parents. Each year, all 3 gander species begin to exhibit breeding capacity in February and reach the peak of reproductive capacity by April, marked by high fertilization rates. With the gradual increase in temperature, the testicular tissue of Hungarian and Wanxi goose gradually diminishes in its ability to produce sperm. the testicular tissue undergoes significant shrinkage by the end of June, resulting in a near loss of sperm production capability, thereby yielding low fertilization rates. However, the Jilin White goose demonstrates the ability to maintain a stable sperm production capacity. Individuals with low sperm motility contribute to increased seed production costs and pose constraints on the industrial development of livestock and poultry varieties. In this study, transcriptomics and proteomics data from gooses testicular of 3 different goose breeds inclouding Jilin white goose, Wanxi white gooseand Hungary white goose sampled in 2 stages, peak of laying cycle (PLC) and end of laying cycle (ELC). In a comparative analysis between PLC and ELC groups (ELC vs. PLC) of 3 breeds, we identified 401,340,6651 differentially expressed genes (DEGs) and 18,225,323 differentially expressed proteins (DEPs), respectively. Differentially expressed genes and proteins were significantly enriched in Gene Ontology (GO) terms such as phosphotransferase activity, cytoskeletal protein binding, microtubule motor activity, channel activity and carbohydrate metabolic process. The KEGG enrichment analysis of the DEGs in testicular showed that most differentially expressed mRNAs participate in the KEGG pathways, including ECM-receptor interaction, MAPK signaling pathway, carbon metabolism, Cell cycle, VEGF signaling pathway, Lipoic acid metabolism and p53 signaling pathway. The differential expression of 4 selected DEGs (SPAG6, NEK2, HSPA4L, SERF1A) was verified by qRT-PCR, and the results were consistent with RNA-seq data. In conclusion, this study reveals the differences in gene expression regulation in testicular tissues of different goose species, and screening candidate genes and proteins related to spermatogenesis.

The article explores the characteristics and outcomes of patients with advanced germ cell tumors who undergo delayed orchidectomy after chemotherapy. The study found that a significant number of patients still had residual tumor or teratoma on histopathology post-chemotherapy. Factors such as pure seminoma diagnosis, IGCCCG risk stratification, and post-chemotherapy tumor markers may predict histological outcomes and help avoid unnecessary orchidectomies. The study suggests that orchidectomies should not be omitted in managing patients with advanced non-seminoma/mixed GCT. [Extracted from the article]

Toxic agents can adversely impact the male reproductive system mainly via activating oxidative stress affecting the seminiferous epithelia, spermatogenesis, sperms, and the testis. Toxic agents lead to the excessive generation of reactive oxygen species (ROS), such as hydroxyl radicals, hydrogen peroxide, and superoxide anions. ROS exert a cytotoxic effect and oxidative damage to nucleic acids, proteins, and membrane lipids. Hesperidin is a pharmacologically active phytoflavone abundantly occurring in citrus fruits, such as oranges and lemons. It has shown various pharmacological properties such as antioxidant, anti-inflammatory, anti-carcinogenic, analgesic, antiviral, anti-coagulant, hypolipidemic, and hypoglycemic effects. Hesperidin has been found to exert protective effects against natural and chemical toxins-induced organ toxicity. Considerable evidence has implicated the testicular protective effects of hesperidin against the toxicological properties of pharmaceutical drugs as well as biological and chemical agents, and in the present review, we discussed, for the first time, the reported studies. The resultant data indicate that hesperidin can exert testicular protective effects through antioxidant properties. [ABSTRACT FROM AUTHOR]

Purpose of Review: Our review delves into the progress across urological malignancies and discusses ongoing challenges and future directions in antibody–drug conjugate (ADC) development, emphasising their transformative potential in cancer care. Recent Findings: ADCs have advanced from hematologic to solid tumours, notably in breast cancer, and are now pivotal in metastatic urological cancers as both monotherapies and in combination regimens, underscored by the FDA's approval of enfortumab vedotin and sacituzumab govitecan for metastatic urothelial cancer. Progress in metastatic prostate cancer, particularly with ADCs targeting PSMA and STEAP1, is noteworthy, although renal cell cancer presents ongoing challenges. There is a continual search for agents in the metastatic, relapsed testicular cancer landscape. Summary: ADCs have emerged as a pivotal innovation in oncology, blending targeted antibody therapy with potent cytotoxic drugs, significantly advancing treatment options for urological malignancies.

BackgroundFetus-in-fetu (FIF) represents an exceedingly rare disease, characterized as an encapsulated and pedunculated vertebrate neoplasm, typically lacking cerebral tissue. The prevalence shows no gender preference. Notably, FIF can cause compressive damage to adjacent organs and tissues, potentially impeding the host's development and maturation.Case presentationA four-month-old male infant was identified, during pregnancy, to have a left-sided pelvic mass on ultrasound. Subsequent evaluations suggested the mass could be a FIF, exhibiting active movement. Surgical exploration revealed that the mass's left boundary was connected to the left spermatic cord and vas deferens. Pathological analysis post-surgery showed the absence of testicular tissue, but the presence of skin tissue, cartilage-like structures, and gastrointestinal elements. Additionally, localized tissue resembling vertebrae confirmed the diagnosis of testicular FIF.ConclusionAn intraperitoneal testicular FIF is extremely rare, with its cause still unknown. This groundbreaking report details the diagnosis and management of such a case. Following a FIF diagnosis, prompt surgical removal is crucial, along with regular follow-up using ultrasound and tumor markers.

Spermatocytic tumors are rare testicular cancers, accounting for less than 1 % of all testicular neoplasms, usually affecting older men. This report details a 35-year-old male with a spermatocytic tumor featuring extensive lymphovascular invasion. The patient had a painless, slow-growing right testicular mass, with normal serum tumor markers. Ultrasound and CT scans suggested malignancy. Post-orchiectomy, histopathology confirmed a spermatocytic tumor with polymorphic cells and lymphovascular invasion. Immunohistochemical staining was positive for SALL4 and CD117, negative for OCT4, AFP, and CD30. The patient underwent chemotherapy and remained recurrence-free for a year, highlighting the need for accurate diagnosis and long-term monitoring.

About 8-12% of couples experience infertility, with male infertility being the cause in 50% of cases. Several congenital and acquired conditions, including chronic diseases and their treatments, can contribute to male infertility. Prostate cancer incidence increases annually by roughly 3%, leading to an increment in cancer treatments that have adverse effects on male fertility. To preserve male fertility post-cancer survival, conventional cancer treatments use sperm cryopreservation and hormone stimulation. However, these techniques are invasive, expensive, and unsuitable in prepubertal patients lacking mature sperm cells. Alternatively, nutritional therapies enriched with bioactive compounds are highlighted as non-invasive approaches to prevent male infertility that are easily implementable and cost-effective. In fact, curcumin and resveratrol are two examples of bioactive compounds with chemo-preventive effects at the testicular level. In this article, we summarize and discuss the literature regarding bioactive compounds and their mechanisms in preventing cancer treatment-induced male infertility. This information may lead to novel opportunities for future interventions. [ABSTRACT FROM AUTHOR]

Malignant germ‐cell‐tumours (GCTs) are characterised by microRNA (miRNA/miR‐) dysregulation, with universal over‐expression of miR‐371~373 and miR‐302/367 clusters regardless of patient age, tumour site, or subtype (seminoma/yolk‐sac‐tumour/embryonal carcinoma). These miRNAs are released into the bloodstream, presumed within extracellular‐vesicles (EVs) and represent promising biomarkers. Here, we comprehensively examined the role of EVs, and their miRNA cargo, on (fibroblast/endothelial/macrophage) cells representative of the testicular GCT (TGCT) tumour microenvironment (TME). Small RNA next‐generation‐sequencing was performed on 34 samples, comprising representative malignant GCT cell lines/EVs and controls (testis fibroblast [Hs1.Tes] cell‐line/EVs and testis/ovary samples). TME cells received TGCT co‐culture, TGCT‐derived EVs, and a miRNA overexpression system (miR‐371a‐OE) to assess functional relevance. TGCT cells secreted EVs into culture media. MiR‐371~373 and miR‐302/367 cluster miRNAs were overexpressed in all TGCT cells/subtypes compared with control cells and were highly abundant in TGCT‐derived EVs, with miR‐371a‐3p/miR‐371a‐5p the most abundant. TGCT co‐culture resulted in increased levels of miRNAs from the miR‐371~373 and miR‐302/367 clusters in TME (fibroblast) cells. Next, fluorescent labelling demonstrated TGCT‐derived EVs were internalised by all TME (fibroblast/endothelial/macrophage) cells. TME (fibroblast/endothelial) cell treatment with EVs derived from different TGCT subtypes resulted in increased miR‐371~373 and miR‐302/367 miRNA levels, and other generic (eg, miR‐205‐5p/miR‐148‐3p) and subtype‐specific (seminoma, eg, miR‐203a‐3p; yolk‐sac‐tumour, eg, miR‐375‐3p) miRNAs. MiR‐371a‐OE in TME cells resulted in increased collagen contraction (fibroblasts) and angiogenesis (endothelial cells), via direct mRNA downregulation and alteration of relevant pathways. TGCT cells communicate with nontumour stromal TME cells through release of EVs enriched in oncogenic miRNAs, potentially contributing to tumour progression. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the changes induced in testicular tissue by administration of dandelion (Taraxacum officinale) extract and its effects on the release of enzymatic antioxidants SOD-2 by immunohistochemical methods in rats with experimental diabetes. Degenerative changes in the seminiferous tubule structure were observed in the testicular sections of the diabetes group. Separations between the basement membrane and the seminiferous epithelium, disruptions in the structure and localization of spermatogenic cells toward the lumen of the seminiferous tubules, thickening of the basement membrane and tunica albuginea, changes in the shape of Sertoli cells, and shrinkage of the nucleus of Leydig cells were observed. While no immunopositivity was observed in spermatogonium and primary spermatocytes in the diabetes group, weak SOD-2 immunoreactivity was observed in other cells of the spermatogenic series and moderate SOD-2 immunoreactivity was observed in the diabetes+dandelion group. In conclusion, it was found that histopathological changes occurred in the testicular tissue and SOD-2 immunoreactivity decreased in diabetes, a chronic metabolic disease. It was concluded that dandelion administration may have beneficial effects on decreased SOD-2 immunoreactivity [ABSTRACT FROM AUTHOR]

Post-traumatic testicular torsion is a rare condition, accounting for approximately 4%-8% of all reported cases of testicular torsion in the literature. Prompt clinical suspicion and intervention are crucial; as testicular torsion is considered a medical and surgical emergency that may lead to testicular necrosis. Ultrasound imaging plays an important role in assessing the integrity of the traumatized scrotum and facilitating early detection of associated testicular torsion. In this case report, we present a neglected post-traumatic testicular torsion in a 13-year-old child that led to orchiectomy.

Testicular tumors (TTs) are rare in children, posing diagnostic and therapeutic challenges. This retrospective study evaluates the diagnostic and prognostic utility of SALL4 and OCT3/4 in pediatric TTs. We analyzed 18 cases of different types of TTs using immunohistochemistry (IHC) to assess SALL4 (Spalt-like transcription factor 4) and OCT3/4 (Octamer binding transcription factor 3/4) expression. SALL4 was positive in 83.3% of tumors, while OCT3/4 was positive in 38.9% of tumors, with a significantly higher prevalence in patients aged 12–18 years compared to those aged 0–11 years (p = 0.013). Mixed germinal cell tumors were significantly more frequently associated with OCT3/4 (p = 0.003), and a high immunostaining expression for SALL4 was observed primarily in yolk sac tumors and embryonal carcinoma. Our findings suggest that SALL4 and OCT3/4 immunostaining can aid in accurate diagnosis and treatment planning, and underscores the importance of OCT3/4 as a predictive factor in pediatric testicular tumors, highlighting its substantial correlation with tumor type and its impact on treatment response. These markers may guide personalized therapeutic strategies, potentially improving patient outcomes.

Shortwave radiation has been reported to have harmful effects on several organs in humans and animals. However, the biological effects of 27 MHz shortwave on the reproductive system are not clear. In this study, we investigated the effects of shortwave whole-body exposure at a frequency of 27 MHz on structural and functional changes in the testis. Male Wistar rats were exposed to 27 MHz continuous shortwaves at average power densities of 0, 5, 10, or 30 mW/cm2 for 6 min. The levels of insulin-like factor 3 (INSL3) and anti-sperm antibodies (AsAb) in the peripheral serum, sperm motility, sperm malformation rate, and testicular tissue structure of rats were analyzed. Furthermore, the activity of superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) content, calpain, and Cdk5 expression were analyzed at 1, 7, 14, and 28 days after exposure. We observed that the rats after radiation had decreased serum INSL3 levels (p < 0.01), increased AsAb levels (p < 0.05), decreased percentage of class A+B sperm (p < 0.01 or p < 0.05), increased sperm malformation (p < 0.01 or p < 0.05), injured testicular tissue structure, decreased SOD and CAT activities (p < 0.01 or p < 0.05), increased MDA content (p < 0.01), and testicular tissue expressions of calpain1, calpain2, and Cdk5 were increased (p < 0.01 or p < 0.05). In conclusion, Shortwave radiation caused functional and structural damage to the reproductive organs of male rats. Furthermore, oxidative stress and key molecules in the calpain/Cdk5 pathway are likely involved in this process. Shortwave radiation has been used in communications, medical and military applications, and its damaging effects on several organs of the human body have been reported in the literature. However, the biological effects of shortwave radiation on the male reproductive system are unknown. The present study, by constructing an animal model of short-wave radiation and analyzing the experimental results, revealed that shortwave radiation could cause functional and structural damage to the reproductive organs of male rats, and that oxidative stress and key molecules in the calpain/Cdk5 pathway might be involved in this process. It will provide organizational data for further studies on the mechanisms of male reproductive damage by shortwave radiation. [ABSTRACT FROM AUTHOR]

Abstract Background The testicular appendix is a residual of the paramesonephric and mesonephric duct, most commonly found close to the superior pole of the epididymis as Morgagni’s cyst. Torsion of such cysts is a common event in children, and the patient usually presents with a palpable testis with a tender mass in its upper pole. The co-existence of two or more appendices is very rare. In addition to the fact that Morgagni’s cyst was the non-twisted one and vas aberrans was, made clinical and radiological diagnosis difficult. Case presentation Our patient, a 15-year-old boy, presented with persistent pain in the right scrotum, a significant palpable mass accompanied by vomiting. Upon surgical exploration, a large dark cyst was found located on the right side of the right testicle with a 720-degree torsion. The cyst was straightened and excised along with a Morgagni’s cyst. The testis was fixed in the right hemiscrotum due to a “bell clapper” deformity that was also a finding. Conclusions Pathological findings were consistent with a twisted cyst of a testicular appendix (vas aberrans). Co-existence of two or more appendices is very rare in addition to the fact that Morgagni’s cyst was the non-twisted one. Usually and in very few cases, a second appendix is found randomly, during surgical exploration for acute scrotum due to torsion of Morgagni’s cyst.

A 63-year-old male presented with left scrotal swelling and the ultrasound showed a large heterogeneous mass consistent with a testicular malignancy. The patient underwent left-sided orchiectomy which showed diffuse large B-cell lymphoma. The patient was then referred for whole-body F-18 fluorodeoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) imaging which showed multiple hypermetabolic foci extending along the left inguinal canal to the retroperitoneum and the left perinephric space, suggesting direct contiguous spread of the tumor along the gonadal vessels, a form of metastasis unique to primary testicular lymphoma, and demonstrated for the first time on FDG PET/CT imaging.

Epidermoid cysts are benign lesions occurring on the skin usually; however, it rarely occurs in the scrotum or testicular area, and even more rarely the association of multiple epidermal cysts on the scrotum and testis. We report a case of multiple epidermal cysts on the scrotum and testis of a 40-year-old man who consulted for scrotal nodules. To our best knowledge, this is the first case to be reported in the literature. In this paper, we will discuss the histogenesis, the ultrasound features, and the complications of scrotal and testicular epidermal cysts.

Aim To determine the effect of red algae extract on the gene expression of catalase and caspase-3 in testicules of rats induced by boric acid (BA). Methods This is experimental research with post-test control group design. Twenty four healthy male Wistar rats were divided into four treatment groups: a healthy group, negative control group, two treatment groups with red algae extract 400mg/kgBW/day (T1) and red algae extract 800mg/kgBW/day (T2). Each group was treated with BA 500mg/kgBW/day for 14 days, whereas the healthy group did not receive BA. In the treatment groups T1 and T2 were given red algae extract for 14 days. On day 15 all treatment groups were terminated and catalase and caspase-3 gene expression were analysed using qRT-PCR. Results In the healthy group, the expression of the catalase gene was 1.39±0.67 and the expression of the caspase-3 gene was 1.06±0.17. In the negative control group, there was a significant decrease in catalase gene expression, 0.68±0.27 (p<0.05), and a significant increase in caspase-3 gene expression, 5.71±2.47 (p<0.05). Treatment groups T1 and T2 showed a significant increase in catalase gene expression, 2.67±0.69; and 2.85±0.64, respectively (p<0.05) and caspase-3, 3.96±1,16 and 1.89±0.84, respectively, compared to the control group. Conclusion: The administration of red algae extract had a significant effect on increasing the expression of the catalase gene and decreasing the expression of the caspase-3 gene. This suggests that red algae extract has the potential to be developed as a protective agent against exposure to the effects of BA. [ABSTRACT FROM AUTHOR]

PRIMETEST did not reach its primary endpoint; thus, primary retroperitoneal lymph node dissection for stage IIA/B seminoma cannot be recommended outside of clinical trials. Nevertheless, surgical treatment of stage IIA/B seminoma seems feasible and may avoid systemic treatment in selected patients. Primary retroperitoneal lymph node dissection (RPLND) for clinical stage (CS) IIA/B seminoma without adjuvant treatment is an experimental treatment to avoid radiotherapy- or chemotherapy-related toxicity from standard treatment. The PRIMETEST trial aimed to prospectively evaluate the oncological efficacy and surgical safety of primary RPLND. PRIMETEST is a single-arm, single-center prospective phase 2 trial. Patients with seminoma, unilateral retroperitoneal lymph node metastases <5 cm, and human chorionic gonadotropin levels <5 mU/ml were included. Patients with CS IIA/B seminoma at initial diagnosis, and recurrence under active surveillance or following adjuvant carboplatin for CS I disease were eligible. Unilateral open or robot-assisted primary RPLND was performed. The primary endpoint of the study was progression-free survival (PFS) after 36 mo. The trial was considered positive if <30% of patients experienced a recurrence. Between 2016 and 2021, 33 patients were accrued (nine with primary CS IIA/B, 19 recurrences during active surveillance, and five recurrences following adjuvant carboplatin). Thirteen and 20 patients had CS IIA and IIB, respectively. Open and robot-assisted RPLND procedures were performed in 14 (42%) and 19 (58%) patients, respectively. After a median follow-up of 32 mo (interquartile range 23–46), ten recurrences were detected (30%, 95% confidence interval: 16–49%); thus, the primary endpoint was not met. Infield recurrences occurred in three of ten patients. The current analysis of risk factors could not identify the predictors of recurrence. Three of 33 patients (9%) presented with pN0. The PRIMETEST trial did not meet its primary endpoint. Nevertheless, PFS of 70% after a median follow-up of 32 mo suggests this approach to be of interest for highly selected patients. Selection criteria, however, need to be defined and validated in a larger prospective cohort of patients. Until then, surgery alone for the treatment of patients with CS IIA/B seminoma cannot be recommended outside of a clinical trial setting. In this study, we investigated primary surgery as an alternative to conventional treatment (chemotherapy or radiation therapy) in patients with metastatic seminoma. The primary objective of the study, to prevent at least 30% of patients from recurrence, was not met. However, certain patients may benefit from this approach and thereby avoid chemotherapy or radiation therapy. Predictive factors need to be analyzed to better select patients for this surgery-only approach. [ABSTRACT FROM AUTHOR]

Background: This study was performed to evaluate the effect of chlorogenic acid (CGA) on spermatogenesis in ionizing irradiated (IR) mice.Methods: In this experimental study, 45 mice were divided into 3 equal groups including group 1 (normal saline), group 2 (IR + normal saline), and group 3 (IR + 5, 10, 20, 40, and 80 mg/kg CGA). After 35 days, the histomorphometry of testicular tissue, cells count in different developmental stages, viability of sperms and finally, fertilization capacity was evaluated. Data were analyzed by ANOVA one-way analysis of variance and post hoc Turkey’s tests.Findings: The results showed that testicular weight, germinal layer thickness and diameter of seminiferous tubules in the IR group were significantly different from the sham and IR + CGA (40 mg/kg) groups. In addition, in the IR group, the number of spermatogonia cells, primary spermatocytes, spermatid and Leydig cells were significantly decreased compared to the sham group. These changes were significantly ameliorated in the IR + CGA (40 mg/kg) group and histological studies did not show any tissue damage. At the same time, the number of germ cells, the thickness of the epithelium of the seminiferous tubules and the diameter of the seminiferous tubules didn’t showe significantly difference with the sham group.Conclusion: The present study shows that CGA (40 mg/kg) can be beneficial against the harmful effects of X-ray exposure by improving histopathological changes in the testis.

Background: Klinefelter Syndrome (KS) is a sex chromosomal syndrome usually with an extra X chromosome (47, XXY) in males, which has various phenotype (mosaicism 47, XXY/46, XY, or more chromosomes 48, XXXY, 49, XXXXY) and clinical features, including eunuchoid body proportions, abnormally long legs and arm span, gynecomastia, ynecomastia, absent or decreased facial and pubic hair, small hyalinized testes, small penis, below-normal verbal intelligence quotient, and learning difficulties. At present, there are no studies on the correlation between the clinical characteristics of patients with KS and the ultrastructural changes of intracellular organelles in testicular tissue in China. Case presentation: Here we report the ultrastructure manifestation of the testis tissues in a KS patient with hypogonadism and androgen deficiency, to find a relationship between ultrastructural changes of organelles and spermatogenic dysfunction, clinical features, timing of surgery and metabolic abnormalities. It has been shown that the spermatocytes are absent and the ultrastructure of Sertoli cells and Leydig cells is obviously abnormal, which may lead to spermatogenic dysfunction, androgen deficiency, impaired glucose tolerance (IGT), and abdominal fat accumulation. Conclusions: Based on the European Academy of Andrology (EAA) Gudilines on Klinefelter Syndrome, this study conducted a retrospective study on the diagnosis and treatment of one adult patient with KS, aiming to provide a standardized diagnosis and treatment for patients with KS. This study is also highly concerned with the correlation between the ultrastructural changes of target organs and clinical symptoms.

Background: The testicular appendix is a residual of the paramesonephric and mesonephric duct, most commonly found close to the superior pole of the epididymis as Morgagni’s cyst. Torsion of such cysts is a common event in children, and the patient usually presents with a palpable testis with a tender mass in its upper pole. The co-existence of two or more appendices is very rare. In addition to the fact that Morgagni’s cyst was the non-twisted one and vas aberrans was, made clinical and radiological diagnosis difficult. Case presentation: Our patient, a 15-year-old boy, presented with persistent pain in the right scrotum, a significant palpable mass accompanied by vomiting. Upon surgical exploration, a large dark cyst was found located on the right side of the right testicle with a 720-degree torsion. The cyst was straightened and excised along with a Morgagni’s cyst. The testis was fixed in the right hemiscrotum due to a “bell clapper” deformity that was also a finding. Conclusions: Pathological findings were consistent with a twisted cyst of a testicular appendix (vas aberrans). Co-existence of two or more appendices is very rare in addition to the fact that Morgagni’s cyst was the non-twisted one. Usually and in very few cases, a second appendix is found randomly, during surgical exploration for acute scrotum due to torsion of Morgagni’s cyst. [ABSTRACT FROM AUTHOR]

During fatal development, the testes grow in the abdomen and descend into the scrotal sac. It can be stopped at any point along its path (cryptorchidism) or migrate to an atypical side (ectopic testis).A 47-year-old man from Somalia's lower Shabelle region was presented to the urology OPD, He had a history of non-tender abdominal mass for the previous four months, An examination revealed a mass in his abdomen that was firm, non-tender, and immobile, an abdominal ultrasound and a contrast enhanced CT abdomen showed a 15-cm heterogeneous bean-shaped mass above the bladder.After patient counseling and informed written consent, a laparotomy was done to remove the tumor. A seminoma of the undescended testis was identified during a histological examination.An intra-abdominal mass with empty scrotum should raise concerns about an intra-abdominal testicular tumor. To prevent/early discover these types of tumors, cryptorchidism should be treated at a young age, particularly before to the first year.

46, XX testicular differences of sex development (DSD) is a rare cause of DSD presenting as a phenotypical male with chromosomal sex of 46, XX. Sex-determining region of the Y chromosome (SRY)-positive 46, XX DSDs have a well-characterized pathogenetic mechanism, whereas in SRY-negative 46, XX DSDs, the pathogenesis is not clearly delineated. Herein, we present a case of a 3 1/2-year-old child who presented with ambiguous genitalia and bilateral palpable gonads. On the basis of a karyotype and fluorescent in situ hybridization, we arrived at a diagnosis of SRY-negative 46, XX testicular DSD. Basal serum estradiol and human menopausal gonadotrophin stimulated estradiol levels and inhibin A blood levels were against the presence of any ovarian tissue. Imaging of the gonads showed bilateral normal-looking testis. A clinical exome sequencing revealed a heterozygous missense variant NR5A1:c275G>A (p. Arg92gln) located at exon 4 in the affected child. Protein structure analysis was further performed, and the variant was found to be highly conserved. Sanger's sequencing showed that the mother was heterozygous for the variant detected in the child. This case highlights the rarity of SRY-negative 46, XX testicular DSD with a unique variant. Largely under characterized, this group of DSDs needs to be reported and analyzed to add to the spectrum of presentation and genetic characteristics. Our case is expected to add to the database, knowledge, and approach to cases of 46, XX testicular DSD. [ABSTRACT FROM AUTHOR]

The aim of this work is to assess DNA damage in the somatic and germ cells in root voles living for a long time under conditions of an increased radiation background and to examine the of manifestation of long-term consequences in their offspring. Using the DNA comet assay (neutral version), we assessed the proportion of cells with DNA damage in the cells of the thyroid, bone marrow and testicular in root voles (Microtus oeconomus Pall.) that lived under conditions of increased radiation background (exposure dose rate − 0.50–20 μSv/h; Komi Republic, Russia) and in their offspring (F1–F3) that were reproduced in a vivarium with a normal radiation background. In animals caught in a radioactively contaminated area, the level of DNA fragmentation in the thyroid gland, bone marrow and testicular remained within the range of values of control animals. The studies that we continued on the offspring of irradiated root voles that were developing in the vivarium under normal radiation background allowed us to identify an increase in the level of DNA DSBs in the thyroid gland in the F1 generation, in the bone marrow and testicular cells in the F2 generation. The modifying effect of urethane showed a similarity in the response of somatic cells in voles that lived for a long time in a radioactively contaminated area and in their offspring that developed with a normal radiation background. The effect of urethane was more conspicuous in thyroid cells that, than in bone marrow cells. The data obtained on voles from the experimental site indicate adaptation to habitat conditions in a radioactively polluted environment. The provocative effect of urethane made it possible to reveal different response of organs with different proliferative activity. Long-term habitation of voles under conditions of an increased radiation background led to genome instability in their offspring. [ABSTRACT FROM AUTHOR]

Testicular tumours in prepubertal children tend to be pure yolk sac tumours detected in stage I and have good prognosis. We describe a case of a 2-year old male child with a mixed testicular tumour presenting with stage IIC disease and managed with retroperitoneal lymph node dissection for residual retroperitoneal disease post adjuvant chemotherapy.

Objective: To analyze the imaging features of primary testicular tumor. Methods: The CT imaging data of 46 cases of testicular tumor confirmed by pathology were retrospectively reviewed. Combined with the other data, the location, attenuation, size, shape, edge, and enhancement patterns of lesions were comprehensively analyzed. Result: All 46 cases of testicular tumor were unilateral. There were 24 cases of seminoma, among whom 16 cases showed uneven mild septal enhancement; 10 cases of endodermal sinus tumor, and 8 cases showed multiple tortuous and thickened blood vessels; 4 cases of teratoma, spot or irregular calcification; 2 cases of mixed germinoma, obvious heterogenous enhancement with no calcification or fat; 2 cases of leiomyoma with clear border, homogeneous density and nhomogeneous enhancement in enhanced scan; 3 cases of diffuse large B cell lymphoma, 2 cases showed clear boundary, uniform density and homogeneous enhancement, 1 case of patchy low density area, with unclear boundary, persistent enhancement, the low density area showed no enhancement; 1 case of malignant mesenchymal cell tumor with thick calcification and moderate enhancement of solid components, accompanied by retroperitoneal lymph node and lung metastasis. Conclusion: CT can distinguish the imaging features of different types of testicular tumors, and have high value in the diagnosis and differential diagnosis of testicular tumors. Thus CT can provide a more accurate basis for clinical treatment.

Egg production performance is an important economic trait in the poultry industry. In previous studies, attention has often been paid to the growth and development of the ovaries, while there has been less research on the testicular tissue of male goose. Due to various factors, there are usually significant differences in the process of testicular spermatogenesis among different goose breeds. The Jilin white goose (JL) is a high-production local goose species in China, domesticated from Anser cygnoides, which has a high egg-laying performance and the egg-laying period can last from February to July. In the production of goose within Jilin Province, the female goose of Jilin White goose is considered as an important maternal parent of synthetic lines, and ganders from Hungarian white goose (HU), Wanxi white goose (WX) and Jilin white goose are the main male parents. Each year, all 3 gander species begin to exhibit breeding capacity in February and reach the peak of reproductive capacity by April, marked by high fertilization rates. With the gradual increase in temperature, the testicular tissue of Hungarian and Wanxi goose gradually diminishes in its ability to produce sperm. the testicular tissue undergoes significant shrinkage by the end of June, resulting in a near loss of sperm production capability, thereby yielding low fertilization rates. However, the Jilin White goose demonstrates the ability to maintain a stable sperm production capacity. Individuals with low sperm motility contribute to increased seed production costs and pose constraints on the industrial development of livestock and poultry varieties. In this study, transcriptomics and proteomics data from gooses testicular of 3 different goose breeds inclouding Jilin white goose, Wanxi white gooseand Hungary white goose sampled in 2 stages, peak of laying cycle (PLC) and end of laying cycle (ELC). In a comparative analysis between PLC and ELC groups (ELC vs. PLC) of 3 breeds, we identified 401,340,6651 differentially expressed genes (DEGs) and 18,225,323 differentially expressed proteins (DEPs), respectively. Differentially expressed genes and proteins were significantly enriched in Gene Ontology (GO) terms such as phosphotransferase activity, cytoskeletal protein binding, microtubule motor activity, channel activity and carbohydrate metabolic process. The KEGG enrichment analysis of the DEGs in testicular showed that most differentially expressed mRNAs participate in the KEGG pathways, including ECM-receptor interaction, MAPK signaling pathway, carbon metabolism, Cell cycle, VEGF signaling pathway, Lipoic acid metabolism and p53 signaling pathway. The differential expression of 4 selected DEGs ( SPAG6, NEK2, HSPA4L, SERF1A ) was verified by qRT-PCR, and the results were consistent with RNA-seq data. In conclusion, this study reveals the differences in gene expression regulation in testicular tissues of different goose species, and screening candidate genes and proteins related to spermatogenesis.
