The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Inhibition of HMGA2 Leads to Reduced Cell Proliferation and Increased Apoptosis in Human Embryonal Carcinoma Cell Lines

Andrology, EarlyView.
ABSTRACT Background The most prevalent solid tumors in young men are testicular germ cell tumors (TGCTs), and embryonal carcinoma is the most common subtype among non‐seminomatous germ cell tumors (NSGCTs). Despite the excellent cure rates of cisplatin‐based chemotherapy, resistance develops in 15%–30% of patients with metastatic cancer, which results ...

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Mesenchymal Stem Cells From a Klinefelter Syndrome Patient: Functional Characterization and Therapeutic Implications

Andrology, EarlyView.
ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Chromosome segregation and recombination in human meiosis: Clinical applications and insight into disjunction errors [PDF]

, 2015
Chromosome copy number errors (or aneuploidy) of gametes and embryos occurs in humans more frequently than in any other studied species, with a spectrum of manifestations from implantation failure to affected live births.

Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.
