Introduction: The epididymis creates an optimal acidic luminal environment for sperm maturation and storage. In epididymal principal cells (PCs), proton secretion is activated by the accumulation of the sodium-proton exchanger type 3, NHE3 (SLC9A3), in apical stereocilia. PCs also secrete ATP, which is hydrolyzed into adenosine by ectonucleotidases.

Background General practitioners (GPs) often expedite indeterminate scrotal lumps for urological evaluation. While a scrotal examination by a urologist is crucial, ultrasound (US) has become a routine component of clinical assessment regardless of the clinical examination findings and the nature of the symptoms. This study aimed to evaluate the efficacy of clinical examination compared to scrotal ultrasound, even when the suspicion of cancer was low.

Adipose tissue regulates energy homeostasis and metabolic function, but its adaptability is impaired in obesity. In this study, we investigate the impact of acute PPARγ agonist treatment in obese mice and find significant transcriptional remodeling of cells in the stromal vascular fraction (SVF). Using single-cell RNA sequencing, we profile the SVF of inguinal and epididymal adipose tissue of obese mice following rosiglitazone treatment and find an induction of ribosomal factors in both progenitor and preadipocyte populations, while expression of ribosomal factors is reduced with obesity.

Background Acute scrotum is a medical emergency commonly encountered in clinical practice, particularly in pediatric and adolescent populations. It is characterized by sudden onset of scrotal pain and may involve swelling, redness, or tenderness. The most common etiologies include testicular torsion, epididymo-orchitis, trauma, and, less frequently, tumors.

Background: Urethral obstruction is a common and life-threatening condition in male small ruminants.
Case Presentation: This case report describes a 3-year old 103 kg Zwartbles breeding ram, presented with the complaint of straining, suspected to have an urethral obstruction. The work-up included clinical examination, laboratory analyses, ultrasound imaging, (contrast) radiography and urine examination.

Sertoli cell tumors are a rare subtype of testicular tumors. This report describes a 55-year-old male who presented with scrotal pain and a palpable mass. Diagnostic imaging revealed a hypoechoic mass in the left epididymis and a hyperechoic mass in the right testis.

Mammalian sperm glycans directly mediate several key life events. However, previous studies have not focused on two key factors that regulate these processes, the terminal glycan pattern and the anchoring sites. Herein, we group the capping monosaccharide sialic acid (Sia) and its capping substrates galactose/-acetylgalactosamine (Gal/GalNAc) into a "correlated terminal glycan pair" (glycopair) and, for the first time, reveal the differences in the aglycone pattern of this pair on spermatozoa using glyco-selective in situ covalent labeling techniques.

Human islets can be transplanted into the portal vein for T1 diabetes, and a similar procedure is being used in a clinical trial for stem cell-derived beta-like cells. Efforts have been underway to find an alternative transplant site that will foster better islet cell survival and function. Although conceptually attractive, the subcutaneous (SC) site has yielded disappointing results, in spite of some improvements resulting from more attention paid to vascularization and differentiation factors, including collagen.

Background: Rete testis dysplasia is a cystic anomaly arising from the rete testis presenting normally in the pediatric population. These cases usually regress spontaneously without the need for surgical intervention. There are rare, reported cases of rete testis dysplasia in adulthood, which have been managed surgically.

The innovative techniques in ultrasound have added a new dimension to investigating superficially located areas such as the contents of the scrotal sac. High frequency transducers, improved technology with the addition of elastography, contrast enhanced ultrasound and microvascular imaging has resulted in a further improvement in diagnostic capabilities. The ability to clearly demonstrate the presence or absence of vascularity within the area under investigation adds an additional dimension to operator confidence in establishing the presence of infarction, global or segmental, or the walls and cavity of an abscess in the testis or epididymis.

Scrotoliths, or "scrotal pearls," are calcified fibrous loose bodies found within the tunica vaginalis, often seen during radiological evaluation or autopsies. Chronic inflammation due to trauma, parasitic infestations, and torsion and subsequent detachment of the appendices of the testis or epididymis are postulated mechanisms suggested for their formation. They are benign but can mimic a tumor.

Acute scrotum in a child is common, and the main underlying conditions are torsion of intrascrotal appendages, epididymitis, testicular torsion and idiopathic scrotal edema. The main diagnostic aim is to confirm or rule out testicular torsion, since this may lead to irreversible ischemia within hours. The diagnostics can be difficult, especially in prepubertal boys, but consist of a thorough history and clinical examination, the use of a clinical prediction score, and sometimes ultrasound with doppler.
