Abstract
Despite the significant morphological changes that occur in the seminal vesicles with aging, the transcriptomic characteristics remain largely unexplored. To address this, we performed bulk RNA sequencing on seminal vesicle samples from mice aged 3, 13, and 21 months to uncover transcriptomic alterations. Our findings reveal that aged seminal vesicles display cystic dilatation, epithelial hypoplasia, disordered muscle layers, fibrosis, and reduced proliferation capability. A comparison between 3-month-old and 21-month-old mice indicated that leukocyte-mediated immunity and leukocyte migration were the most significantly upregulated biological processes among differentially expressed genes (DEGs). Notably, several DEGs associated with "leukocyte migration," such as Vcam1, Cxcl13, and Ccl8, exhibited an increasing trend in transcriptomic and protein expression at three different time points in the seminal vesicles of mice. Additionally, we identified multiple aging-associated DEGs, including P21 and Tnfrsf1b. Two genes (Cd209f and Ccl8) were consistently upregulated across all six regions of the male reproductive glands (testis, epididymis, and seminal vesicle) in the comparison of bulk RNA datasets from 3-month-old and 21-month-old mice. These analyses highlight an enhanced state of immune and inflammatory response in aged seminal vesicles. This study represents the first exploration of the overall transcriptome landscape of seminal vesicles in a murine model of natural aging, offering new insights into the mechanisms underlying aging-related seminal vesicle dysfunction.

Abstract
Male infertility has seen an increase in prevalence with cases of azoospermia estimated to affect 10%-15% of infertile men. Confirmation of azoospermia subsequently necessitates an early causal differentiation between obstructive azoospermia (OA) and nonobstructive azoospermia (NOA). Although less common when compared to NOA, OA can represent upward 20%-40% of cases of azoospermia. While there are a multitude of etiologies responsible for causing NOA and OA, correctly distinguishing between the two types of azoospermia has profound implications in managing the infertile male. This review represents an amalgamation of the current guidelines and literature which will supply the reproductive physician with a diagnostic armamentarium to properly distinguish between NOA and OA, therefore providing the best possible care to the infertile couple.

Abstract
The presence of microplastics (MPs) in human fluids and organs is a great concern, since, as highlighted by recent studies on animal models, they could cause alterations of several physiological functions, including reproduction. In this study, semen samples collected from men living in a polluted area of the Campania Region (Southern Italy), were analyzed to assess the presence of MPs. N. 16 pigmented microplastic fragments (ranging from 2 to 6 μm in size) with spheric or irregular shapes were found in six out of ten samples. All the detected MPs were characterized in terms of morphology (size, colour, and shape) and chemical composition by Raman Microspectroscopy. Chemical composition showed the presence of polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), polyvinylchloride (PVC), polycarbonate (PC), polyoxymethylene (POM) and acrylic, suggesting ingestion and/or inhalation as a route of exposure to environmental MPs. In this work, we propose for the first time a mechanism by which MPs pass into the semen most likely through the epididymis and seminal vesicles, which are the most susceptible to inflammation.

Abstract
Seminal vesicles play an important role in the male reproductive system, producing seminal fluid and thus adequate environment for sperm. However, mechanisms underlying secretory functions of the seminal vesicles’ epithelium have not been defined yet. The aim of the present study was to characterize expression and immunolocalization of selected membrane transporters and carriers in the seminal vesicles. The study included biopsy specimens collected from non-affected parts of seminal vesicles from 53 patients of Caucasian origin subjected for prostatectomy. RT-PCR was used to define expression of 15 genes coding for ABC-family and 37 genes encoding 37 SLC-family transporters/carriers. Immunohistochemistry was used to define localization of 6 transporters. In the seminal vesicles, the following membrane transporters and carriers were defined: ABCA1, ABCB1, ABCB5, ABCB6, ABCC1, ABCC2, ABCC3, ABCC4, ABCC5, ABCC6, ABCG2, SLC01C1, SLC02B1, SLC04A1, SLC04C1, SLC10A1, SLC15A1, SLC15A2, SLC16A1, SLC16A3, SLC19A1, SLC22A1, SLC22A3, SLC22A11, SLC22A18, SLC22A4, SLC22A5, SLC28A1, SLC2A9, SLC33A1, SLC47A1, SLC47A2, SLC51A, SLC51B, SLC7A5, SLC7A6. Age-dependent expression was evidenced for ABCB1, ABCG2, SLC04C1, SLC15A1, SLC16A1, SLC22A11, SLC22A18, SLC47A1 and SLC47A2. ABCG2, P-gp, MRP1, MRP3, MCT1 and LAT1 were localized in the apical membrane and P-gp in the basolateral membrane of the seminal vesicle epithelium. The expression of the membrane transporters and carriers in the seminal vesicle epithelium confirms its secretory and barrier functions.

Abstract
An ejaculatory duct cyst is a rare and challenging problem for a urologist. Diagnosing these cases may be difficult as prior case reports showed that the condition has various clinical presentations from asymptomatic to major complications, such as recurrent urinary tract infections and infertility. We aimed to report a 26-year-old married man with seemingly unknown infertility, which was confirmed to be due to an ejaculatory duct cyst obstructing both ejaculatory ducts.

Abstract
The differential diagnosis between obstructive and nonobstructive azoospermia is the first step in the clinical management of azoospermic patients with infertility. It includes a detailed medical history and physical examination, semen analysis, hormonal assessment, genetic tests, and imaging studies. A testicular biopsy is reserved for the cases of doubt, mainly in patients whose history, physical examination, and endocrine analysis are inconclusive. The latter should be combined with sperm extraction for possible sperm cryopreservation. We present a detailed analysis on how to make the azoospermia differential diagnosis and discuss three clinical cases where the differential diagnosis was challenging. A coordinated effort involving reproductive urologists/andrologists, geneticists, pathologists, and embryologists will offer the best diagnostic path for men with azoospermia.

Abstract
PURPOSE OF REVIEW The aim of this review is to provide an overview of surgical treatment options for male infertility including varicocelectomy, treatment of ejaculatory duct obstruction, vasovasostomy, and sperm extraction, and to review recent advances in techniques and technologies that may improve operative outcomes. RECENT FINDINGS Microscopic subinguinal varicocelectomy has been shown to have the highest success rates with lowest rates of complications, and may be facilitated by the use of Doppler, indocyanine green angiography, and the 4K3D operating video microscope. The standard treatment for ejaculatory duct obstruction by transurethral resection of the ejaculatory ducts has changed little over time, but vesiculoscopy may allow for temporary dilation of an obstruction to allow for natural conception, while also offering diagnostic capabilities. Use of the robotic platform has gained popularity for vasectomy reversals but controversy remains regarding the cost-effectiveness of this option. Recently, a reinforcing suture technique has been described for vasovasostomy to minimize anastomotic breakdown and reversal failure. Finally, gray-scale and color-enhanced ultrasound may improve ability to predict successful sperm retrieval during extraction procedures. SUMMARY Though the fundamentals of surgical treatment options for male infertility have changed little with time, technological advancements have contributed to improved surgical outcomes over recent years.

Abstract
Posterior urethral valves (PUVs) are frequently recognized during the perinatal period. Delayed diagnosis is reported usually within the first decade of life with diverse clinical presentations. In the current case report, we describe a 45 years old man patient who presented with aspermia and primary infertility for 8 years in whom his diagnostic workup revealed radiological imaging suggestive of PUVs. This phenomenon was confirmed by cystourethroscopy that showed obstructive valve. Endoscopic ablation resulted in significant improvement of his seminal parameter with successful conception.

Abstract
Background/Aims Seminal vesicle (SV) stones are a rare, and thus readily misdiagnosed condition in practice. Understanding the etiology, diagnosis, and management are crucial to guide a urologist's care, and are provided in this literature review. Methods The inclusion criteria for the literature search, using the search engines MEDLINE® and PubMed was conducted using a combined query of "seminal vesicle stone" and the following keywords: calculi, hematospermia, calcification, and transrectal ultrasound (TRUS). Results The etiology of SV stones is currently unknown where majority of the patients present with having painful ejaculation and hematospermia. However, clinicians have reported potential etiologies by categorization as an inflammatory or non-in-flammatory. A majority of the previous cases had shown multiple stones being present in the SV duct system that are typically diagnosed through radiological examination such as TRUS, MRI, or plain radiographs. Amongst the many imaging approaches, TRUS remains the primary imaging diagnoses of SV calculi. Transurethral seminal vesiculoscopy has shown to be used in an abundant of the case reports to be an ideal surgical approach for managing small SV stones. In regard to larger stones, a transperitoneal laparoscopic protocol is proper. Conclusion The current imaging techniques have increased the case reports and diagnosis of SV calculi; however, more research is warranted for understanding the pathogenesis of the formation of SV stones. An optimal management of the extraction of SV stones depends on a number of factors such as size and location.
