A Systematic Review on the Presentation and Management of Segmental Testicular Infarction
ABSTRACT Background Segmental testicular infarction (STI) is a rare and likely underdiagnosed cause of acute scrotal pain. Its clinical and imaging presentation often mimics testicular torsion or malignancy, frequently leading to unnecessary surgical intervention.

ABSTRACT Background Male accessory gland inflammation (MAGI) comprises a heterogeneous group of inflammatory conditions that may differentially affect the seminal microenvironment and sperm function. However, whether transrectal ultrasound (TRUS)‐defined MAGI phenotypes correspond to distinct biological profiles remains insufficiently characterized ...

Associations Between Sperm DNA Fragmentation and Lifestyle Factors
ABSTRACT Background Sperm DNA fragmentation index (DFI) has been proposed as a supplementary biomarker to traditional semen parameters in the evaluation of male infertility. However, its determinants and clinical relevance remain unclear, particularly regarding modifiable lifestyle factors.

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Father–Son Comparison of Reproductive Traits
ABSTRACT Background Little is known about the relative contribution of genetic and environmental factors on male reproductive function. Objectives We studied in a cross‐sectional setting, whether testicular function and genital size correlate in father–son pairs.
