Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

Andrology, EarlyView.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.
