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 ...

ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

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.

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

ABSTRACT Background As sex chromosome trisomies (SCTs), including 47, XXX, 47, XXY, and 47, XYY, are associated with increased risk for neurodevelopmental challenges, studying SCTs may help in understanding the role of early parental caregiving in shaping neurodevelopmental phenotypes of this genetically at‐risk population.

ABSTRACT Background Obesity and low testosterone levels are closely interconnected, with the FTO gene being the most robust genetic determinant of body mass index (BMI). However, whether this primary genetic driver of obesity directly influences the hypothalamic‐pituitary‐testicular (HPT) axis remains unclear.

ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...
